Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blood pressure measurement pipe connector for connecting a blood pressure measurement device that measures blood pressure by an oscillometric method and an air pipe that connects a cuff attached to a living body.

[0002]

[Prior art]

 When measuring the blood pressure of a patient transported in an ambulance or the like on the car, it may not be possible to undress the patient and wrap the cuff around the arm. In such a case, the blood pressure is measured by wearing a finger cuff on the patient's finger. However, since the arteries of the fingers are peripheral blood vessels and are thin, it may not be possible to measure them due to impaired circulation, and in this case, there is no choice but to use an arm cuff wrapped around the arm. Therefore, in the past, the blood pressure measuring device for the arm cuff and the blood pressure measuring device for the finger cuff were exchanged and used properly.

[0003]

[Problems to be solved by the device]

 However, it was difficult to mount both the arm cuff blood pressure monitor and the finger cuff blood pressure monitor in a narrow ambulance. There is also a method in which the connection tube connected to the blood pressure measuring device extending from the arm cuff and the finger cuff is replaced with a blood pressure measuring device to measure, but in this method, the connection tube is used for stability of wearing, etc. Since a relatively soft tube is used, there was a problem that the tube was touched by the tube of the ambulance while it was connected to the blood pressure measurement device, and vibrations were transmitted, causing noise in the blood pressure measurement.

The present invention has been made in view of such a situation, and it is possible to easily connect the air ducts of a plurality of cuffs attached to a living body and accurately measure blood pressure. An object of the present invention is to provide a blood pressure measuring pipe connecting device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention according to claim 1 is a blood pressure measuring pipe connector for connecting an air pipe connecting a blood pressure measuring device and a cuff attached to a living body of a subject. There is a pipe connector body attached to the arm of the living body via a belt, and a plurality of types of cuffs attached to the living body provided at one end of an air flow path formed in the pipe connector body. Each of the air pipes is connected to one end thereof, and the other end of the air pipe is detachably connected to the connecting portion.

The plurality of types of cuffs described in claim 2 are an arm cuff wound around an arm portion and a finger cuff attached to a finger portion.

[0007]

[Action]

 In the blood pressure measuring pipe connector of the present invention having the above-mentioned configuration, the air pipe connected to the arm cuff or the finger cuff can be easily attached to and detached from the pipe connecting device connected to the blood pressure measurement device. The measurement can be easily switched by the cuff. Further, since the pipe connecting tool is attached to the arm via the belt, it is possible to reduce the fluctuation of the connected air pipe and improve the accuracy of blood pressure measurement. Furthermore, by making the piping connector and the air piping of the blood pressure measuring device a piping of a material that is harder than the air piping connected to each cuff, the vibration of the vehicle, for example an ambulance, will not be picked up, and the blood pressure measurement value will not be picked up. The noise that enters can be reduced.

【Example】

 An embodiment of the blood pressure measuring pipe connector of the present invention will be described below with reference to the drawings.

1 to 3 show the configuration of an embodiment of the present invention. A fitting portion 2 is integrally formed on one side of the connector main body 1 formed in a substantially cubic shape, and a laterally long through hole 3 is formed in the fitting portion 2. As shown in FIG. 3, one end of a belt 4 is inserted and fixed in the through hole 3. Further, an air passage 5 is provided so as to penetrate substantially in the center of the connector body 1 in a direction parallel to the through hole 3, and an enlarged connecting portion 6 is formed at one end of the air passage 5. There is.

A tubular taper joint 7 is press-fitted into the hollow cylindrical connecting portion 6 through a collar portion 7 a formed so as to concentrically project near one end, and contacts the bottom surface of the connecting portion 6. An O-ring 8 is attached to the outer circumference of one end. An O-ring 8 hermetically seals the inner circumference of the connecting portion 6 and the outer circumference of the taper joint 7. A cylindrical taper guide 9 is press-fitted between the outer circumference of the taper joint 7 on the side projecting from the connecting portion 6 and the inner circumference of the connecting portion 6. Further, the taper joint 7 and the taper guide 9 are integrally fixed to each other by a pin 10 which is press-fitted into the connector body at right angles to the axial direction. The taper joint 7 is connected to a cuff-side air pipe, which will be described later, and the air pipe on the blood pressure measuring device side is connected to one end of the air flow path 5 opposite to the connecting portion 6. There is.

Next, an example of connecting air piping will be described with reference to FIG. The connector main body 1 is attached to the lower arm portion 11 of the subject's arm, and the belt 4 having one end fixed to the mounting portion 2 of the main body 1 is wound around the lower arm portion 11 to form the connector main body. 1 is fixed to the lower arm portion 11. This fixing is performed through a surface adhesive tape provided on the end portion of the belt 4. An arm cuff 13 is wound around the upper arm 12 of the subject's arm, or a finger cuff 15 is attached to the subject's finger 14. Then, either one of the air pipe 16 connected to the arm cuff 13 and the air pipe 17 connected to the finger cuff 15 is detachably connected to the taper joint 7 of the connector body 1. Further, one end of the air flow path 5 formed in the connector main body 1 opposite to the connecting portion 6 is connected to a blood pressure measuring device (not shown) via an air pipe 18.

According to this embodiment, when the blood pressure is measured by the oscillometric method, the air pipes 16 or 17 connected to the arm cuff 13 or the finger cuff 15 (shown by phantom lines) are connected to the connector body 1. By detachably connecting to the provided taper joint 7, it is possible to easily connect the measurement by any one of the cuffs. Further, since the connector main body 1 is attached to the arm via the belt 4, it is possible to reduce the fluctuation of the connected air pipe 16 or 17 and improve the accuracy of blood pressure measurement.

In the above embodiment, the case where the blood pressure is measured using the arm cuff 13 or the finger cuff 15 has been described, but the combination of cuffs is not limited to this. Further, the pipe connection structure by the taper joint 7 and the taper guide 9 is an example, and other structures may be used.

[0014]

[Effect of device]

 As described above, according to the blood pressure measurement pipe connector of the present invention, the air pipes of a plurality of types of cuffs are selectively detachably connected via the pipe connector body attached to the arm. , The accuracy of blood pressure measurement can be improved by switching the air ducts of multiple types of cuffs. Furthermore, by making the piping connector and the air piping of the blood pressure measuring device a piping of a material that is harder than the air piping connected to each cuff, the vibration of vehicles such as ambulances will not be picked up and blood pressure will not be picked up. The noise that enters the measurement value can be reduced.
