[Technical field to which the invention belongs]

 The present invention relates to a stethoscope for easily measuring the blood pressure of a person wearing heavy clothes.

[0002]

[Prior art]

 Various methods have been devised for measuring blood pressure, but the most popular method is auscultation. Auscultation is a method in which a manchette (band wrapping a rubber air bag) is wrapped around the upper arm and air is pumped into the manchette, which pressurizes and closes the brachial artery blood vessels. When the pressurization is slowly reduced and the blood flow resumes, the blood flows turbulently in the stenotic part of the blood vessel, and the turbulence occurs intermittently in accordance with the contraction of the heart and emits a pulsating sound (a Korotkoff sound). Although it is a small sound, the Korotkoff sound can be auscultated when a stethoscope is placed close to the inside of the upper arm. When the manchette is pressurized and the blood flow is closed, the pressure is slowly reduced, and when the Korotkoff sound is first auscultated, the manchette pressure is the systolic blood pressure (systolic blood pressure). The pressure of the Manchette when the flow is lost and the Korotkoff sound cannot be auscultated is the diastolic blood pressure (diastolic blood pressure). It is widely used because blood pressure monitors with a pump and a pressure gauge connected to a manchette, and simple equipment with only a stethoscope can easily obtain accurate blood pressure values. Although measurements can be made on wrists and ankles as well, the measured values are different, and the values measured on the upper arm are standard. The stethoscope used for blood pressure measurement is a general one used for internal medical treatment, which can be measured. The one with sensitivity is a stethoscope for blood pressure measurement. In addition to the auscultation method, there is a blood pressure measurement method using an electronic sphygmomanometer such as an oscillometric method, but this is not related to the present invention.

[0003]

[Problems to be solved by the invention]

 When measuring blood pressure by auscultation, a manchette is wrapped around the upper arm, and a stethoscope is closely attached to the inside of the upper arm to listen to Korotkoff sounds.However, it is necessary to listen to small Korotkoff sounds without fail. is there. In the past, blood pressure measurement was performed in a quiet indoor environment such as a medical institution with light clothing.However, due to the enactment of the Paramedic's Act, even people wearing various clothes, such as outdoors or in an ambulance, have been measured. It became necessary to measure. For patients with heavy clothing, measurement should be taken by removing clothes or rolling up the sleeves, but it is difficult to measure in situations where clothes cannot be removed (coldness or patient symptoms), and when clothes are removed In some cases, blood pressure values may change due to changes in body temperature.

[0004] When rolling up the sleeves, if there is a button or the like on the cuff, it can be easily rolled up by removing the button, but otherwise it is difficult to roll up to the upper arm and it is difficult to forcibly raise the cuff. When rolled up, the tightening can compress the blood vessels and change the readings.

[0005] The high-sensitivity stethoscope has increased sensitivity so that Korotkoff sounds can be auscultated from above clothing, but the thickness of clothing is also limited. It is also sensitive to ambient noise, so it is difficult to auscultate Korotkoff sounds in places with much noise.

[0006] In a place where there is vibration, the sound collecting part or the tube of the stethoscope emits a fricative sound and is mixed as noise, so that auscultation of Korotkoff sound becomes difficult.

[0007]

[Means for Solving the Problems]

 In order to reliably hear the slight sound (Korotkoff sound) emitted when an arterial blood vessel is constricted, the arterial side must be located closest to the arterial blood vessel, that is, close to the skin or with a thin piece of clothing in between. Ideally, a sound collection section should be set up toward. For a thickly-wearing person, an extension rod can be attached to the sound collector and inserted from the cuff to reach the upper arm, so that the sound collector can always be placed at the ideal position.

In order to block external noise, it is possible to solve the problem by providing a soundproofing measure on the rear side of the sound collecting unit. By placing the sound collecting section under the manchette and the clothing, a soundproofing effect can be obtained in the manchette and the clothing layer, and noise can be cut off.

In order to prevent frictional noise due to vibration, it is possible to solve the problem by fixing the sound collecting portion. By placing the sound collecting section under the manchette and the clothing, the sound collecting section is pressed by the pressure of the manchette and can be fixed.

[0010]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. In the figure, the extension rod A is a thin plate or a rod made of metal, synthetic resin, or the like, and is formed with sufficient strength and length to insert the sound collecting portion from the cuffs, push under the clothing, and reach the upper arm. The distal end portion 1 of the extension rod is fixed to the back of the sound collector B of the stethoscope, and various fixing methods are conceivable depending on the shape of the stethoscope. In the figure, a crescent-shaped push plate 2 that can be pushed in while supporting the back surface of the sound collecting portion B is provided on the distal end portion 1 of the extension rod, and a metal sandwich plate 3 having elasticity is attached. The locking portion 4 of the plate is formed to be locked to the tube connecting pipe portion 5 on the back of the sound collecting portion. When the extension rod is not required, it can be removed so that it can be removed. As shown in FIGS. 4 and 5, the attachment procedure is as follows. The push plate 2 of the distal end portion 1 of the extension rod is applied to the rear convex portion 6 of the sound collector B of the stethoscope, and the extension rod is left with the rear convex portion 6 as a fulcrum. , And the sandwiching plate 3 is simply sandwiched between the tube connecting pipe portions 5.

【Example】

 The stethoscope according to claim 1 is a commercially available stethoscope for measuring blood pressure. Remove the thick jumpers and coats, remove the cuff buttons on the shirt, pinch the clothing in the area where the cuffs can be pinched, and create a space for inserting the sound collector of the stethoscope. Manipulate the sound collecting part with the insertion rod and insert the sound collecting part from the cuff to the upper arm. No special technique is required, and even a seven-sleeve sleeve can be inserted into the upper arm without difficulty. If you can reach the upper arm, search for the sound collector from above the clothing and move to the optimal position of the upper arm. The blood pressure measurement can be carried out in a usual manner by winding a manchete.

[0012]

[Effect of the invention]

 It is easy to position the sound collector of the stethoscope to the optimal position on the upper arm by using the insertion rod even when wearing a thick sweater or sweatshirt or trainer. The Korotkoff sound can also be heard clearly, making it possible to measure blood pressure for people with heavy clothing and in places with noise and vibration. Blood pressure can be measured with a stethoscope from the top of a shirt without the need for an insertion rod if two or more shirts are used, but it is not possible to measure blood pressure on thick clothing such as sweaters and trainers. Therefore, extension rods are useful.
