Description

Technical Field

[0001] The utility model relates to the technical field of medical and sanitary products, in particular to a disposable sterile urinary catheterization bag. Background Art

[0002] Disposable sterile catheterization bags are widely used in clinical practice. They are mainly used for patients with urinary retention and urinary anus. They can be used for catheterization before and after surgery. During use, they should be strictly followed in accordance with the operating specifications. This is a disposable item and reuse is strictly prohibited.

[0003] Existing disposable sterile catheter bags are often connected to a belt-shaped catheter bag. Urine flows into the catheter bag from the catheter. This catheter bag often has no carrying device and needs to be placed in a pocket. In this way, if it is accidentally squeezed by the body, urine will flow back into the catheter. At the same time, the traditional catheter bag has no anti-reflux device. After being squeezed, urine can easily be squeezed out of the catheter bag, and even urine leakage may occur. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a disposable sterile urinary catheterization bag, which solves the problem that the existing disposable sterile urinary catheterization bags are often connected to a strip-shaped urinary catheterization bag, and urine flows into the urinary catheterization bag from the urinary catheterization bag. Such urinary catheterization bags often have no carrying device and need to be carried in a pocket. In this way, if the body is accidentally squeezed, the urine will flow back into the urinary catheterization bag. At the same time, the traditional urinary catheterization bag has no anti-reflux device, and the urine can be easily squeezed out of the urinary catheterization bag after being squeezed, and even urine leakage occurs.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A disposable sterile urinary catheterization bag comprises a urine inlet tube arranged at the top of the urinary catheterization bag, the urine inlet tube passes through the top of the urinary catheterization bag and is connected with a urine leakage tube, a support plate is arranged inside the urine leakage tube, a return spring is fixedly installed at the top of the support plate, a pressure block is fixedly installed at the top of the return spring, a blocking block is fixedly installed at the top of the pressure block, and the blocking block is clamped and connected with the urine inlet tube.

[0007] Preferably, the blocking block is arranged in the shape of a quadrangular pyramid.

[0008] Preferably, a symmetrical overflow box is provided in the urinary catheter bag, an absorbent sponge is provided inside the overflow box, and a plurality of urine inlets are opened on one side of the overflow box.

[0009] Preferably, card interfaces are provided on both sides of the urinary catheter bag, one of the card interfaces is connected to a left elastic band by sewing, and a first Velcro is provided on one side of the left elastic band, and the other card interface is connected to a right elastic band by sewing, and a second Velcro is provided on the other side of the right elastic band.

[0010] Preferably, the second Velcro is longer than the first Velcro.

[0011] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0012] The disposable sterile urinary catheter bag provided by the utility model is provided with a reset spring. When urine presses the blocking block, the pressing block moves down and squeezes the reset spring. The blocking block moves away from the urine inlet tube, and the urine flows into the urine leakage tube, and then enters the urinary catheter bag through the urine leakage tube to complete the collection of urine. When there is no pressure influence of urine above the blocking block, the reset spring is reset, the pressing block moves up, and the blocking block is stuck in the urine inlet tube to complete the blocking of the urine inlet tube, thereby preventing urine from leaking or squeezing backflow. At the same time, by providing a four-sided pyramid-shaped blocking block, it is prevented that urine remains on the top of the blocking block, thereby causing reflux and secondary infection.

[0013] The utility model is provided with a water-absorbing sponge. When urine enters the urinary catheter bag and accumulates to a certain extent, it will enter the overflow box through the urine inlet and then be absorbed by the water-absorbing sponge, thereby further avoiding the situation of backflow.

[0014] The utility model is provided with a card interface, a left elastic band, a first Velcro, a right elastic band and a second Velcro for use together, so that the left elastic band and the right elastic band can be fixed to the patient's leg by bonding the first Velcro and the second Velcro, thereby greatly improving the carrying convenience of the patient.
