Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a sleeve pipe for bladder pressure measurement. BACKGROUND

[0002] When doctors diagnose the abnormal urination of patients, the bladder function and urethral function during the urine storage period and the urination period need to be diagnosed and judged respectively; during the normal urination process of human body, the bladder tightens and the urethra relaxes, while during the urine storage period, it is just the opposite, usually showing that the bladder relaxes and the urethra contracts. If the bladder or the urethra cannot normally function during the urine storage period or the urination period, the bladder or the urethra will have abnormal function, and the purpose of bladder pressure measurement is to understand the function of the detrusor and the urethra during the urine storage period and the urination period.

[0003] At present, when pressure measurement is performed, a syringe is used to forcibly push physiological saline for pressure measurement, instead of relying on atmospheric pressure to flow into the bladder naturally, which will affect the pressure of the reflux liquid in the catheter and artificially intervene the whole pressure measurement process; in addition, the existing pressure measurement structure cannot meet the real-time monitoring of the bladder pressure of the patient.

[0004] For example, a Chinese patent with the patent number CN215227712U and the name of a bladder pressure measurement tube, through a three-way valve, the physiological saline injection device and the extension pipe are connected with each other, and the extension pipe is kept in a vertical state, physiological saline is injected into the extension pipe through the physiological saline injection device, flows into the bladder through the urinary catheter, after the physiological saline in the extension pipe is stable, the liquid level height is quickly read out through the scale on the scale card, and thus the bladder pressure value is obtained.

[0005] However, the above-mentioned prior art has the following deficiencies in clinical application: first, the existing artificial injection of physiological saline will make the patient have a transitional nervous emotion, which is not conducive to the smooth progress of bladder pressure measurement; second, the existing device completely depends on the opening relationship of the three-way valve, and cannot be individually opened and closed according to the needs, which is not conducive to the pressure measurement operation; third, after the pressure measurement is completed, the whole device needs to be removed to let the patient urinate, which is not conducive to the direct collection of the urine of the patient. UTILITY MODEL CONTENTS

[0006] In view of the defects in the above-mentioned prior art, the utility model aims to provide a sleeve pipe for bladder pressure measurement, which is designed as a whole from the safety, convenience and hygiene of the structure in use, so as to effectively solve the problems in the background art.

[0007] The technical solution of this utility model adopts the following approach: the connection between the infusion tube, pressure measuring tube, drain tube, and guide tube is set as a trident-shaped one-to-three multi-port connection tube structure to reduce pressure loss during the pressure test; the intravenous infusion tube is used to replace the traditional injection method to inject physiological saline into the patient, changing manual injection to atmospheric pressure injection to reduce the influence of human factors in the injection process; by setting up the drain tube, the pressure test sleeve does not need to be removed immediately when draining waste fluid after the patient's pressure test is completed.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A cannula for bladder pressure measurement includes a multi-port connecting tube, on which an infusion assembly, a pressure measurement assembly, and a drainage assembly are connected sequentially from left to right. A drainage tube is provided at the bottom of the multi-port connecting tube and is connected to a catheter in the patient's body.

[0010] As a further preferred embodiment of the above technical solution: the multi-port connecting pipe adopts a trident-shaped hollow structure, and each port of the multi-port connecting pipe is provided with an anti-slip groove.

[0011] As a further preferred embodiment of the above technical solution: the infusion assembly includes an infusion tube, a flow regulator and a first pressing clamp. One end of the infusion tube is connected to the left port of the multi-port connecting tube, and the other end is connected to an external infusion bag / bottle. The flow regulator and the first pressing clamp are both installed on the infusion tube.

[0012] As a further preferred embodiment of the above technical solution: the pressure measuring component includes a pressure measuring tube, a transparent graduated tube, a waste liquid bag, and a second pressing clamp. One end of the pressure measuring tube is connected to the middle tube of the multi-port connecting tube, and the other end is connected to the waste liquid bag. The transparent graduated tube is sleeved on the pressure measuring tube, and the second pressing clamp is installed on the pressure measuring tube and located below the transparent graduated tube.

[0013] As a further preferred embodiment of the above technical solution: the drainage assembly includes a drainage pipe and a third pressing clamp. One end of the drainage pipe is connected to the right port of the multi-port connecting pipe, and the other end is connected to an external urine bag. The third pressing clamp is installed on the drainage pipe.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a multi-port connecting tube, the pressure measuring tube, infusion tube, drainage tube, and catheter are connected to form a whole. The pressure measuring tube and the drainage tube are arranged on the same axis, avoiding the influence of the pressure measuring tube and the drainage tube on the entire pressure measuring process. By setting up a multi-port connecting tube, the traditional method of injecting saline with a syringe is changed to an infusion method that relies on atmospheric pressure, effectively reducing the influence of human factors on bladder pressure measurement and making the pressure test results more accurate.

[0016] By setting the waste liquid bag at the tail end of the pressure measuring tube, the physiological saline expelled by the patient's bladder during the pressure measuring process is collected in the waste liquid bag, so as to prevent the waste liquid from flowing back to the infusion tube and causing pollution.

[0017] By setting the drainage pipe, the end of the drainage pipe is inserted into the urine bag, and after the bladder pressure test is completed, the waste liquid can be drained into the urine bag through the drainage pipe without disassembling the pressure measuring tube, which is helpful for clinical operation.
