Description

Bladder pressure measuring device for urine drainage tube

Technical Field

The utility model belongs to the field of medical equipment, in particular to bladder pressure measuring device for an urine drainage tube.

Background

Some patients with severe disease require insertion of a drain, but to reduce urinary tract infection. In addition to enhancing the nursing of the indwelling catheter and keeping the urethra unobstructed in clinical nursing work, most nursing contents also include the flushing of the bladder of a patient with a catheter. Proper bladder irrigation can effectively reduce the occurrence of urinary tract infection in catheterized patients. When the bladder of a patient is flushed in a closed flushing mode, the height of the drainage tube is slightly lower than a pubis combined plane so as to be beneficial to emptying liquid in the bladder, the drainage tube entering a urine bag needs to be closed during flushing, the flushing liquid is kept in the bladder for about 20 minutes after 100mL of liquid is injected into the bladder, then the drainage tube communicated with the urine bag is opened, and the flushing liquid flows out. The flushing is repeated for 3-4 times, the speed cannot be too high, otherwise, the flushing liquid can damage the bladder wall, and the infection chance is increased. The physician's judgment is facilitated if the pressure of the bladder after the fluid filling can be observed in real time.

The above background disclosure is only provided to aid understanding of the inventive concepts and solutions of the present invention, and it does not necessarily pertain to the prior art of this patent application, and it should not be used to assess the novelty and inventive aspects of this application without explicit evidence that such contents are disclosed at the filing date of this patent application.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bladder pressure measurement device that urine drainage tube was used for accurate feedback intravesical hydraulic pressure.

In order to achieve the above object, the utility model provides a bladder pressure measuring device for urine drainage tube, including infusion bag, collection urine bag, be used for inserting urethral first pipe and a plurality of switching pipe, in other schemes, can use the cylinder to replace infusion bag, then give medical personnel manual control.

By adopting the scheme, the transition pipe and the miniature pressure sensor can be conveniently and integrally taken away, and the transition pipe and the miniature pressure sensor are cleaned, so that the miniature pressure sensor can be repeatedly used. As shown in fig. 2, the diameter of the transition pipe is larger, and the miniature pressure sensor is connected and fixed on the transition pipe from the side.

As an improvement of the scheme, the head end and the tail end of the transition pipe are inserted into or wrapped on the corresponding ports of the first guide pipe in an interference fit mode. In this arrangement, the large diameter transition tube wraps around the first conduit from end to end, as shown in fig. 2. When the disassembly is needed, the two can be separated by applying larger external force. Correspondingly, the first catheter, the urine collection bag, the infusion bag and the corresponding switching catheter with lower cost are all disposable.

As an improvement of the scheme, a circle of sealant is arranged on the outer sides of the head end and the tail end of the transition pipe. By adopting the scheme, the sealing performance of the two is improved.

As an improvement of the scheme, the infusion bag and the urine collecting bag are provided with scales. By adopting the scheme, medical staff can judge the bladder volume of the patient according to the relation of the inlet flow and the outlet flow, and the bladder volume can be used for assisting in guiding treatment.
