Description
Technical Field
The invention relates to the field of medical instruments, in particular to a respiratory pressure measuring device.
Background
The Valsalva (Valsalva) maneuver is a deep inspiration followed by a breath hold, and then a forced expiration maneuver, during which the tight epiglottis is countered. Clinical significance of valsalva maneuver: increase intrathoracic pressure, reduce venous return apparently; exciting the vagus nerve; such as (1) paroxysmal supraventricular tachycardia, whereby the vagus nerve is excited by the valsalva action to terminate the supraventricular tachycardia episode; (2) when the cardiac myopathy is hypertrophic obstructive, the blood returning volume is reduced through the action of Valsalva so as to enhance the noise, and the noise is identified; (3) mitral valve prolapse causes mitral regurgitation, which enhances the noise through the valsalva maneuver.
Briefly, the valsalva maneuver requires the patient to exhale hard, but not so much, creating some pressure in the chest cavity. At the same time, to achieve the clinical significance of valsalva, the expiratory pressure generated should reach 40mmHg and be maintained for 10-15 seconds.
At present, the method which is most used in hospitals is the simplest method, namely, a patient blows a needle tube without a needle head and blows an injector, so that the patient is assisted in performing the valsalva action. This method has the following disadvantages: (1) because the syringe is not specifically designed for respiratory pressure testing, it is not guaranteed that the respiratory pressure of each patient reaches 40 mmHg. (2) Because the needle tube head is small, the patient is easy to leak air when exhaling, and the effect is affected.
There are also devices for measuring respiratory pressure and assisting the patient in performing valsalva maneuvers. The basic components of these devices are generally composed of a gas gauge, a conduit and a mouthpiece. The conventional gas gauge is used, and is an electronic type or a mechanical type. The pipe connects the mouthpiece with the pressure gauge to form a measuring gas path. The patient blows at the mouthpiece end, and the real-time pressure of blowing is displayed by the gas pressure gauge, thereby assisting the patient in performing standard and effective valsalva movements. The device is not specially designed for assisting the valsalva action, and has the following disadvantages: (1) the cost is high, the price of the existing pressure gauge (the measuring range is 40mmHg) is high, and the disposable use cannot be realized. (2) The existing pressure gauge is generally large in size and inconvenient to carry, and a patient is not suitable for using at any time and any place. (3) The mouthpiece and the air pressure indication are not specially designed, so that the air leakage is easy to occur when the patient uses the device, and the patient cannot easily identify whether the required pressure is achieved.
The breathing pressure detection auxiliary device (CN 2126988860U) provided by the patent Valsalva has the defects of non-disposability and easy cross infection. The auxiliary detection device disclosed in patent valsalva maneuver assisting device (CN 202131426U) and a valsalva test detector (CN208464054U) can be connected with a disposable joint, but the whole device is expensive and cannot be a truly disposable medical product.
It is therefore desirable to provide a low cost, convenient and intuitive means for measuring air pressure and for assisting a patient in performing valsalva maneuvers that allows the patient to use a disposable, inexpensive respiratory air pressure measurement device.
Disclosure of Invention
The invention aims to solve the problems that the conventional valsalva breathing pressure measuring device is not provided with a specially designed mouthpiece, is expensive and is not an integral disposable medical product, and provides a disposable device which can observe whether the expiratory pressure meets the standard or not in real time and is low in integral cost.
The invention provides a respiratory pressure measuring device for achieving the purpose, which comprises a shell, a spring, a clapboard, a telescopic balloon, a bent pipe and a mouthpiece, wherein the spring, the clapboard, the telescopic balloon, the bent pipe and the mouthpiece are arranged in the shell; a partition board is arranged below the telescopic balloon, a spring is connected below the partition board, and the spring is arranged at the bottom of the shell; the shell is provided with a mark and a transparent observation window for observing the position of the partition plate; the mouthpiece, the elbow and the balloon form a closed passage with only the mouthpiece as an opening; when gas is injected from the mouthpiece, the telescopic saccule can extend to prop against the partition plate, the partition plate moves to compress the spring, and the position of the partition plate corresponds to the mark on the shell, so that the corresponding air pressure in the saccule is read.
Wherein a location on the housing labeled 40mmHg indicates that the patient's valsalva maneuver is up to standard each time the partition reaches that location. The outer end of the mouthpiece is elliptical and the inner end is circular. The bend is designed to be a 45 degree bend.
Preferably, the collapsible balloon cannot expand radially but can only contract axially, with the internal air pressure directly transferring force to the septum. The partition board receives the force generated by the telescopic saccule and the elastic force generated by the spring and separates the saccule from the spring. The elastic force generated by the spring can be balanced with the force generated by the air pressure in the balloon, so that the clapboard reaches the corresponding position.
Optionally, the outer surface of the balloon is sprayed with vapor deposition parylene. Or the outer surface of the saccule is sprayed with a polytetrafluoroethylene coating. Or the outer surface of the balloon is sprayed with silica gel hand feeling oil.
The breathing air pressure measuring device has the advantages that the breathing air pressure measuring device is low in cost, convenient and visual to measure air pressure and is used for assisting a patient to perform valsalva actions, and the patient can use the breathing air pressure measuring device which is disposable and cheap.
