Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a bed for blood collection used when collecting blood to save a third person's life, and particularly relates to a bed for blood collection in which the bed body is swingable. .

[Conventional technology]

Conventionally manufactured blood collection vehicles are mainly of closed type, and due to their structure, the blood sample recipient lies on a fixed bed to receive the blood sample.

By the way, recently, with the adoption of an open body structure in blood collection vehicles, a more functional blood collection environment is required, and with the spread of 400CC blood collection, a chair-shaped blood collection vehicle with performance including anemia prevention is being developed. A bed is requested. In addition, a bed for blood collection that can be used not only in blood collection vehicles but also in centers and general hospitals is desired.

[Problem that the invention attempts to solve]

However, in the structure of the conventional blood sampling bed described above, since the bed body is fixed, it takes time to get on and off the bed body, and if the blood sample patient develops anemia during blood collection, the patient must lower his or her head. There were problems such as not being able to do it.

Therefore, for example, it may be possible to raise and lower the bed main body so that getting on and off the bed can be done easily, but this structure has the problem of increasing the weight and size of the bed as a whole including the lifting device, making it expensive.

Furthermore, since space is required for the stroke of the bed body and for the installation of the lifting device, there is also the problem that it is not possible to provide a storage space below the bed body.

Furthermore, as a countermeasure against anemia, etc., it is conceivable to separate the upper body support part and lower body support part of the bed body, fix the lower body support part to the base body, and support the upper body support part rotatably on the base body. but,
In this structure, since the lower body support part is fixed, the stroke of the upper body support part must be large in order to lower the upper body sufficiently relative to the lower body in the case of anemia. There is a problem that a large amount of wasted space is generated. Furthermore, during normal blood collection, the angle formed between the upper body support part and the lower body support part becomes large, so there is also the problem that the posture of the blood sample recipient when lying on the bed body becomes unnatural.

The present invention aims to solve these problems.It is easy to get on and off, and it also allows the person to sleep in a comfortable position.In addition, if the person to be blood sampled has anemia, the patient's head can be easily removed. It can be lowered, and the space around the bed itself can be used effectively, providing a more functional blood collection environment when used in blood collection trucks, centers, general hospitals, etc., and has a simple structure and is inexpensive. The purpose is to obtain a bed for use.

[Means for solving problems]

The blood collection bed of the present invention has a base body, an upper body support part, a waist support part, and a leg support part that are integrally curved continuously and smoothly on the upper surface, and the base body is formed in the vicinity of the intermediate part of the waist support part and the upper body support part. a bed main body swingably supported on the bed body; a blood sampling arm stand located on the side of the upper body support part of the bed main body and movably supported on the base body; The bed is equipped with an elevating drive device that is engaged near the foot support portion of the bed main body and swings the bed main body and holds it at a desired position.

[Effect]

In the blood sampling bed of the present invention, when a blood sample patient gets on and off, the base is moved around the middle part between the waist support part and the upper body support part by the lifting drive device whose upper end is engaged near the leg support part of the bed main body. The bed body, which is swingably supported by the body, is tilted so that its leg support portions are lowered, and when blood is collected, the bed body is swung in the direction in which its foot support portions rise, and the bed body is continuously and smoothly curved. Blood is collected while the person to be blood sampled lies in a comfortable position on the bed body, which has an upper body support section, a waist support section, and a leg support section, and the patient's arm is placed on a blood collection arm stand that has been moved to an appropriate position. Furthermore, when the person to be blood sampled develops anemia during blood collection, the bed body is swung to lower the upper body support part and raise the leg support part.

Furthermore, a caster 4 with a stopper is provided at each corner of the lower surface of the base body 1. Further, inside this base body 1, a storage container 5 is provided as appropriate.

Reference numeral 11 denotes a lifting drive device, which includes a prime mover, for example, an electric motor 12, disposed on the inside front side of the base 1, and a front surface approximately T whose lower part is connected to the electric motor 12 via a rack and whose upper part protrudes above the base 1. It has a letter-shaped rod 13. That is, this rod 13 is driven by the electric motor 12 to move up and down. Further, on the right side surface of the protrusion 2 of the base body 1, an operating section 14 for controlling the elevating drive device 11 is provided.

Reference numeral 21 denotes a chaise longue-shaped bed main body, and the rear, center, and front parts of its upper surface are formed into an upper body support part 22, a waist support part 23, and a leg support part 24, respectively. And these supporting parts 22, 23, 2
4 is continuously and smoothly curved integrally. That is, the upper surface of this bed main body 21 extends from the upper body support section 22 to the waist support section 23 when viewed from the side.
It is formed in a concave shape whose curvature gradually increases over time, and the foot support part 24 is formed in a convex shape. Further, the lower surface of the bed main body 21 is formed substantially parallel to the upper surface and in the form of a zigzag side surface. especially,
A convex corner portion 25 is formed below the intermediate portion between the upper body support portion 22 and the waist support portion 23, and a concave corner portion is formed below the leg support portion 24. 26 is formed. and,
This bed main body 21 has a convex corner 25 engaged with the step 3 of the base 1, and an upper end of the rod 13 of the lifting drive device 11 is fixed to the concave corner 26. In particular, it is supported on the base 1 so as to be swingable around the convex corner 25 as a pivot.

Reference numeral 31 denotes a blood sampling arm stand, which is located on the right side of the upper body support section 22 of the bed main body 21 and is movably supported by the base body 1. That is, the tip of the horizontal arm portion 34 of the arm body 33 having an elevational shape is pivoted to the bearing piece 32 protruding from the right side surface of the protrusion 2 of the base body 1 with the vertical direction as the rotation axis. Ori,
In addition, a shaft 36 vertically installed on one side in the longitudinal direction of the blood collection table 31 is attached to the vertical arm portion 35 formed in a cylindrical shape of the arm body 33, and can be horizontally rotated and vertically movable and held at any position. is inserted into.

Next, the operation of this embodiment will be explained.

When the person to be blood sampled gets on the bed main body 21, the operating section 14 is operated to drive the elevating drive device 11 and lower the rod 13 by a predetermined amount. Then, the bed main body 21 swings to the position shown by the two-dot chain line in FIG. 1 and is held at that position. That is,
At this time, the bed main body 21 has its upper body support portion 2
2 rises, the waist support part 23 and the leg support part 24 descend, and are tilted in a downward direction toward the leg support part 24. Therefore, the blood sample recipient can easily get on the bed body 21.

When the person to be blood sampled lies on the bed body 21, the elevating drive device 11 is driven to raise the rod 13, and the bed body 21 is swung to the position shown by the solid line in FIG. In this state, the blood sample recipient lies on the bed body 21 with the upper body partially raised.

Next, as shown by the chain line in the drawing, the arm body 33 is rotated, and the blood sampling arm stand 31 is rotated and moved up and down to move the blood sampling arm stand 31 to an appropriate position. Then, the blood sample recipient places his or her arm on the blood sample arm stand 31 and receives the blood sample.

If the blood sampled person develops anemia during blood collection, the elevating drive device 11 is driven to swing the bed body 21 to the position shown by the one-dot chain line in FIG. 1. That is, by lowering the upper body support section 22 and raising the leg support section 24, the relative position of the head relative to the lower body of the person receiving blood can be lowered, and emergency treatment for anemia can be performed. At this time, remove the blood sampling needle from the arm of the blood sample recipient.
The blood sampling arm stand 31 is moved to a position out of the way.

After blood collection, the elevating drive device 11 is driven to lower the rod 13, and the bed body 21 is again swung to the position shown by the two-dot chain line in FIG. In this state, the bed body 21 is tilted in a downward direction toward the leg support portion 24, and the waist support portion 23 is positioned low, so that the blood sample recipient can easily get off the bed body 21, just like when getting on the bed. Can be done.

The movement method of the bed main body 21 to facilitate getting on and off the bed and as a countermeasure against anemia is a swinging movement using a part of the bed as a pivot. Since it is swingably supported on the base body 1 near the intermediate part between the bed body 23 and the rod 13 of the lifting drive device 11 is engaged near the foot support part 24, the stroke of the bed body 21 can be made small and the center of gravity can be reduced. Since the bed main body 21 is supported by sandwiching them, the support becomes stable.
Therefore, since the elevating drive device 11 can also have a simple structure, a space for the storage compartment 5 can be secured within the base body 1, and the cost can be reduced.

In addition, the bed main body 21 is integrally molded, and includes an upper body support portion 22, a waist support portion 23, and a leg support portion 2.
4 is continuously and smoothly curved, so that the blood sample recipient can always sleep in a comfortable position on the bed body 21.

In addition, since the bed main body 21 has a structure in which the entire bed body 21 swings integrally, the upper body support part 21
2, the foot support part 24 rises, so the amount of movement of the upper body support part 22 from the normal blood sampling position in anemia is smaller than in a structure in which only the upper body support part 22 is rotated. can. That is, the empty space that should be secured behind the upper body support section 22 for movement can be reduced.

Furthermore, as mentioned above, since the blood sampling arm stand 31 is movably supported on the base 1, it can be moved to a more appropriate position during blood sampling, and when not in use, the arm body 33 can be rotated to A blood sampling arm stand 31 can also be stored behind the support section 22.

Thus, according to the above configuration, a more functional blood collection environment can be provided. This bed for blood collection can be used not only in blood collection vehicles but also in centers and general hospitals.

In addition, the rod 13 is the prime mover for lifting and lowering.
In addition to the electric motor 12, a hydraulic pump, a compressed air pump, or the like may be used.

Further, in order to swing the bed body 21, a swing arm using a rotary motor may be used instead of the rod 13.

Further, the blood sampling arm stand 31 may be provided on the left side of the bed main body 21 instead of the right side, or may be provided on both sides.

[Effect of idea]

According to the present invention, the bed body is swingably supported on the base body near the intermediate part of the waist support part and the upper body support part, and the lifting drive device is provided whose upper end is engaged near the foot support part of the bed body. Therefore, by swinging the bed body and tilting the leg support parts in the downward direction, it is possible to easily get on and off the bed body, and it is also possible to easily get on and off the bed body. To do this, the bed body is rocked to lower the upper body support part and raise the leg support parts to raise the legs higher than the head and supply a large amount of blood from the heart to the head of the blood sample recipient. Safety can be ensured, and since the upper body support part, waist support part, and leg support part are continuously and smoothly curved as one body, the blood sample recipient can always sleep in a comfortable position.
In addition, since the blood sampling arm stand is movable, it can be moved to an appropriate position when blood is being collected, and it can also be moved to a position where it does not get in the way when not in use. Since it has an integrally swinging structure, its stroke can be made smaller and the space around it can be used more effectively, making it more functional for use in open-body blood collection vehicles, centers, and general hospitals. Furthermore, since the drive mechanism of the bed body is simple as described above, the cost can be reduced.
