Disposable catheter for measuring human body temperature and abdominal pressure

Abstract

The invention relates to a disposable catheter for measuring the human body temperature and the abdominal pressure. On the basis of a disposable catheter for measuring the human body temperature, a pressure sensor wire is added into a washing chamber, one end of the pressure sensor wire is connected to a pressure sensor, the pressure sensor is arranged on a head of the catheter; and the other end of the pressure sensor wire extends outside a washing connecting opening and is connected to a conversion plug of the pressure sensor. The disposable catheter is disposable in use, is simple in structure, is low in cost, is convenient to use, and can achieve human body temperature test, abdominal pressure test, and comparison of the body surface temperature and the body internal temperature of a patient during surgery, or first aid, or inconvenient movements; The human body temperature and the abdominal pressure of the patient can be continuously measured in high accuracy through the same one catheter, pains of the patient can be decreased, and economical burden of the patient can be reduced; and a probe of the disposable catheter can continuously measure the human body temperature and the abdominal pressure in high accuracy without any external power supply, the accuracy can reach +0.2 to -0.2 DEG C, and exact information can be fed back to a relevant medical worker.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable catheter for measuring body temperature and abdominal pressure. Background technique [0002] To measure the intra-abdominal pressure of patients, medical personnel generally use the simple method of measurement. The method of simple measurement is to measure the intra-abdominal pressure by measuring the inferior vena cava pressure, intragastric pressure and bladder pressure. Among them, the cystometry method is simple, It is accurate and has good correlation. Therefore, the method of measuring intra-abdominal pressure using the bladder is widely used; the specific method is as follows: let the patient lie on his back, insert the catheter into the bladder under aseptic operation, after the bladder is emptied, Inject 50-100ml of sterile infiltrated saline into the bladder with the catheter, clamp the catheter, connect the catheter to the urine bag, connect the catheter to the drain...

AI Technical Summary

Problems solved by technology

[0003] At present, the prior art has a temperature measuring catheter with a single function, such as patent No. 2012204636224, which is named: a one-time temperature measuring catheter. This kind of catheter not only solves the problem of repeated use of cross-contamination, especially It solves the temperature test of the patient during the operation, or during the first aid, or when the patient is inconvenient to move, and the comparison of the body surface and internal temperature;

[0004] There is also a urinary catheter with a single function for measuring the intra-abdominal pressure of a patient, such as patent No. 2013207107496, which is named: a urinary catheter for pressure measurement, and a catheter for pressure measurement is specially set up in the catheter A pressure measurement channel, with a pressure measurement connection device at the channel outlet;

[0005] Above-mentioned two kinds of urinary catheters have a single function, and can only be used for clinically measuring body temperature or abdominal pressure for patients alone. When measuring abdominal pressure for patients, use the catheter for measuring abdominal pressure. Urinary catheter not only increases the pain to the patient, but also increases the economic burden;

[0006] In order to overcome the problem of the above-mentioned single function, the inventor Ge Hu invented a disposable catheter for measuring body temperature and abdominal pressure. The patent number is 2014201592685. This catheter is used to measure abdominal pressure at the other end of the catheter One end of the pressure measuring tube is connected to the discharge tube behind the discharge interface, and the inner cavity of the pressure measuring tube is connected with the inner cavity of the discharge tube, and a urine flow control device is installed on the discharge tube and the pressure measuring tube; The other end of the manometric tube is provided with a manometer joint connected with the manometer; this kind uses the same catheter to measure abdominal pressure and body temperature at the same time, although it can solve the problem of using the same catheter at the same time. The problem of measuring the intra-abdominal pressure and body temperature of patients, but the structure is still relatively complicated, the cost is high, and the use is not very convenient
