Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an input code distributor for distributing input codes such as electrocardiograms connected to a patient on a bed in a cardiac catheterization laboratory, for example.

[Summary of the idea]

The present invention is an input cord distributor, in which the distributor main body, to which multiple input cords are distributed and connected, is attached to the side of the patient in bed, and is rotatable so that the input cord connection surface is set upward and laterally. This prevents the input cords from becoming tangled, facilitates the connection of the input cords, and protects the input cord connection surface from chemicals and the like.

[Conventional technology]

For example, when connecting the input cord of an electrocardiogram or blood pressure transducer to a patient on the bed in a cardiac catheterization lab, operating room, ICU (intensive care unit), etc., the configuration shown in Figure 5 has conventionally been adopted. .

That is, FIG. 5 shows an example of an electrophysiological test in a cardiac catheterization laboratory. In the figure, 1 indicates a bed, on which patient A is lying.
A trolley 2 is placed on the side of the bed, and this trolley 2
A head amplifier 3 for an electrocardiogram, a blood pressure transducer, etc. is fixed to the bed, and a plurality of input cords 4 connected to the head amplifier 3 are led above the bed, and the electrodes at the tips are connected to predetermined parts of the patient. has been done.

By the way, in such a cardiac catheterization test, it is desirable to use a carbon lead wire for the input cord in order to prevent the input cord from being sensitive to X-rays during chest X-ray imaging. However, since this carbon lead wire is not shielded, it has the disadvantage that noise such as artifacts easily enters the wire, and it is also easy to break. Conventionally, the carbon lead wire 4a is used only at the tip of the input cord 4, and is used for measurement. At times, the electrodes are connected to a predetermined part of the patient A with the input cord 4 widened as shown in the figure so that the portion of the input cord 4 other than the carbon lead wire 4a is not seen in the X-rays.

[Problem that the invention attempts to solve]

In such a conventional input cord connection structure, each input cord is connected to the patient separately, so the input cords cross and become intertwined, resulting in poor operator operability and patient The surrounding area becomes unsanitary, and the area around the bed becomes unsanitary.
There is also a risk that the input cord may get caught and cut when moving left/right or up/down.

Furthermore, since the input cords are connected to the patient in a widely expanded state, the input cords form a loop, which may cause artifacts to be mixed in.

Therefore, as a countermeasure to improve this problem, it is possible to fix the head amplifier directly to the side of the head and connect the input cord to the patient over the shortest distance, but even in this case, the connection part of the input cord on the head amplifier Crossing of input cords is unavoidable, and if the head amplifier is fixed with its input cord connection facing upward, if the chemical used on the head is spilled, this chemical will There is a risk that the head amplifier's input cord connection may be damaged, and even if the input cord connection is fixed in a horizontal position, in this case the head amplifier's input cord connection may be considerably lower than the operator's eye level. Because of the position, it is not easy to connect the input cord from the side.

The present invention has been developed in view of these points, and provides an input code distributor that can suitably distribute and connect input cords to patients on the bed, and can also set the input cord connection section upwardly and laterally. The purpose is to eliminate the above problems.

[Means for solving problems]

To achieve the above object, the present invention provides a distributor for distributing a plurality of input cords 8 to be connected to predetermined parts of the patient A on the bed 1, the input cords being connected to a predetermined part of the patient A on the side of the bed 1. a distributor main body 9 which is attached correspondingly to the main body 9 and is rotatable so that the input cord connecting surface faces upwardly and laterally;
It has magnets 14 and 15 as holding members that lock and hold the input cord at a rotational angle such that the input cord connecting surface faces upwardly and laterally.

[Effect]

According to the input code distributor configured as described above, when connecting the input cord 8 to the distributor main body 9, the distributor main body 9 must be set and held in a state with the input cord connecting surface facing upward. This makes it easy to connect the input cord, and during measurement, by setting and holding the distributor body 9 with the input cord connecting surface facing the horizontal direction,
Even if the medicinal solution used on the bed is spilled,
The input cord connection surface can be protected from this chemical solution.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 3. Parts corresponding to those of the conventional example shown in FIG.

A plurality of connection cables 5 are connected to the head amplifier 3 fixed to the trolley 2, and each connection cable 5 is brought together by a flexible tube 6 and guided to the bed 1 side. 7 into a number of input codes 8 corresponding to patient A.

This distributor 7 is attached to the side of the bed 1 at a location corresponding to the vicinity of the patient A, and includes a distributor body 9 and a support 10 for supporting the distributor body 9 on the bed 1. Become.

The distributor main body 9 is formed into a rectangular box shape from a metal having magnetic adsorption properties, such as iron. A flexible tube 6 is connected to the distributor main body 9, and a connecting cable 5 inside the flexible tube 6 is connected to the distributor main body 9.
The terminals 1 are arranged in parallel on the surface of the distributor main body 9 via predetermined internal wiring configured inside the distributor main body 9.
It is branched into 1.

The connector 8a at the proximal end of each input cord 8 is fitted and connected to each terminal 11 of this distributor main body 9, and the electrode at the tip of each input cord 8 is connected to the terminal 11 of the distributor body 9.
are connected to corresponding predetermined parts of the respective parts.

As is clear from the figure, the terminals 11 of the distributor main body 9 are arranged in accordance with the order of the input cords 8 that are actually connected to predetermined parts of the patient A. This prevents input code 8 from crossing each other.

On the other hand, a support body 1 on which this distributor body 9 is supported
0 is formed by bending a sheet metal material, for example, and its upper end is bent into an inverted U shape with respect to the vertical surface portion 10a to form an engaging portion 10b. , the support body 1 is engaged with the center part of the frame 1a provided on the side of the bed 1.
0 is supported in a fixed state with respect to the bed 1.
Further, at the bottom of this support body 10, a vertical surface portion 10a is provided.
A horizontal surface portion 10c is formed by bending the vertical surface portion 10a into an L-shape, and projecting pieces 10d are provided protruding from both side edges of the vertical surface portion 10a. And this protrusion 1
A distributor main body 9 is pivotally attached to the terminal 0d via a shaft 12 on both side surfaces thereof, so that the surface on which the terminal 11 is provided, that is, the connection surface 13 of the input cord is connected to the distributor main body 9. It is supported by a support body 10 in a rotatable state so as to face upward and laterally.

Moreover, the distributor main body 9 is attached to this support body 10.
A magnet is arranged and fixed as a holding member for locking and holding the input cord connecting surface 13 in the respective rotational positions in which it faces upwardly and laterally.

That is, on the vertical surface portion 10a of the support body 10, the first
A magnet 14 is fixed thereto, and by magnetically adsorbing the distributor body 9 to the first magnet 14, the distributor body 9 is connected to the input cord connecting surface 1.
3 is locked and held in a state facing upward, and a second magnet 15 is fixed to the horizontal surface portion 10c of the support body 10.
By magnetically adsorbing the distributor main body 9 to the input cord 5, the distributor main body 9 is held in place with the input cord connecting surface 13 facing in the horizontal direction.

According to the input code distributor 7 of this example configured as described above, the distributor main body 9 is attached to the side of the bed 1 corresponding to the side of the patient A.
The length of the input cord 8 can be shortened,
This reduces noise such as artifacts and prevents input cords from tangling with each other, making the area around Patient A neat and tidy, improving various operability, and being effective in terms of health and safety. There is no fear that the input cord 8 will be caught and cut when the input cord 1 is moved.

Also, since input code 8 is short, input code 8
Carbon lead wire can be used for the entire length of
Therefore, the input code does not appear on X-rays, which is effective when taking X-rays.

Further, since the distributor main body 9 is configured to be locked and held in the rotational position where the input cord connecting surface 13 faces upward and sideways, the connector 8a of the input cord 8 can be connected to the terminal 11. In this case, as shown in FIG. 3A, by setting the input cord connection surface 13 of the distributor main body 9 to face upward, the terminal 11 will face the direction of the surgeon's face. This makes it easier to insert the connector 8a into the terminal 11, improving work efficiency. In addition, by setting the input cord connection surface 13 of the distributor body 9 in a horizontal direction during measurement, as shown in FIG. 3B, even if the chemical solution used on the bed 1 is spilled, This chemical solution connects connector 8a and terminal 11.
The reliability of the input cord connection surface is improved because it does not invade the connection part of the input cord.

In the above embodiment, a magnet is used as a holding member for the rotational position of the distributor main body 9, but a hook-and-loop fastener, for example, may be used instead of the magnet. That is, as shown in FIG. 4, one side 16a of the first surface fastener is fixed to the vertical surface 10a of the support 10, and the other side 16a of the first surface fastener is fixed to the corresponding surface of the distributor body 9. 16b is fixed. Further, one side 17 of the second surface fastener is attached to the horizontal surface portion 10c of the support body 10.
a, and the other side 17b of the second hook-and-loop fastener is fixed to the corresponding surface portion of the distributor main body 9.

When the distributor main body 9 is set in the rotational position with the input cord connection surface 13 facing upward, the distributor main body 9 is locked in the rotational position by bonding the first hook and loop fasteners 16a and 16b. (FIG. 4A) and when the distributor main body 9 is set in the rotational position with the input cord connecting surface 13 facing in the lateral direction, the second hook-and-loop fasteners 17a and 1
By adhering 7b, the distributor main body 9 is locked and held in its rotational position (FIG. 4B).

Further, as the mechanism for holding the rotational position of the distributor main body 9, various modifications can be considered, such as a structure using a toggle spring, in addition to the above structure using a magnet or hook-and-loop fastener.

Furthermore, although this embodiment shows an example in which the input code distributor 7 is attached only to one side of the bed 1, the distributor 7 may be attached to multiple locations on the bed 1, for example, on both the left and right sides. . In this case, the length of the input cord can be further shortened by dividing the input cord into each distributor according to the connection site for patient A, thereby preventing the contamination of arch-acts and the entanglement of input cords with each other. Even greater effects can be obtained in such aspects.

Furthermore, it goes without saying that the other parts are not limited to the configuration shown in this embodiment, and that various embodiments can be adopted.

[Effect of idea]

As described above, according to the present invention, since the distributor main body is attached to the side of the bed near the patient, the length of each distributed input cord is shortened, and noise contamination such as artifacts is thereby reduced. At the same time, since the input cords can be prevented from tangling with each other, the area around the patient is kept in order, which is effective in terms of operability and health and safety, and there is no fear that the input cords will get caught and cut when the bed is moved. In addition, since the main body of the distributor can be rotated so that the input cord connection surface faces upward and sideways, it is easy to connect the input cord, and during measurement, the input cord connection surface can be used for cleaning chemicals, etc. It has various effects that were not available in the past, such as being able to protect people from damage, and its practicality is great.
