detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the invention shown in the drawings and described with reference to the drawings are merely exemplary, and the invention is not limited to these embodiments.

Referring to Fig. 1 to Fig. 3, in the embodiment of the utility model, the disposable urinary catheter includes a trachea patient end 1, a urination end 2, a tube body 3, a water injection end 4, and a balloon 5.

The patient end 1 includes a patient end lumen 11 , a plug 12 disposed at the end of the patient end 1 , and at least one urine inlet 13 disposed on the side wall of the patient end and communicating with the patient end lumen 11 . The plug 12 is hemispherical and transitions smoothly with the side wall of the patient end 1, so as to avoid injury to the patient when the patient end 1 is inserted into the urethra. The surface of the urine inlet 13 is smooth without burrs, and the urine enters the inner cavity of the patient end 11 from the urine inlet 13 .

The urination end 2 has a through conical urination inner cavity (not shown), and a urination opening 21 arranged at the largest diameter port of the urination end 2 . The tapered design facilitates the discharge of urine.

The tube body 3 has a through tube lumen 31 , one end of which communicates with the patient end lumen 11 , and the other end connects with the smallest diameter port of the urination end 2 . The tube body also includes a development line (not shown) arranged on the side wall, so as to be developed under X-ray detection and facilitate observation.

The water injection end 4 includes a tapered water injection pipe body 41, a water injection chamber 42, a one-way valve 43 connected to the smallest diameter port of the water injection pipe body 41, the largest diameter port of the water injection pipe body 41 is connected with the pipe body 3, and the water injection chamber 42 One end is embedded between the inner wall and the outer wall of the pipe body 3 , and the other end communicates with the one-way valve 43 . Through the setting of the water injection end 4, the patient's bladder can be cleaned at any time, and the utility model is convenient to use and simple to operate.

The balloon 5 is sheathed on the tube body 3 , and the balloon 5 communicates with the water injection cavity 42 . That is, water enters the balloon through the water injection cavity 42 instead of entering the internal lumen 31 of the tube. The size of the balloon 5 can be adjusted arbitrarily through the control of the water injection volume of the balloon 2 by the water injection chamber 42 .

In another embodiment of the present application, the disposable urinary catheter also includes a flushing end 6, which includes a tapered flushing tube body 61, a flushing cavity (not shown), and the smallest diameter port of the flushing tube body 61 The connected valve 62 and the largest diameter port of the flushing pipe body 61 are connected with the pipe body 3 , and the flushing cavity communicates with the internal cavity 31 of the pipe body.

Specifically, the material of the patient end 1 , the urination end 2 , the tube body 3 , the water injection tube body 41 and the balloon 5 is silica gel, and the material of the one-way valve 43 is polycarbonate.

The flushing pipe body 61 is made of silica gel, and the valve 62 is made of polycarbonate.

This application is a silicone urinary catheter, which has a wide inner diameter, and the inner lumen will not form calcium deposits and deposits, which will cause unsmooth drainage, and completely solve the problem of difficult extubation due to catheter blockage. The application is sterilized by ethylene oxide, and is a sterile product for one-time use, which not only avoids cross-infection, but also is convenient and clean.

When in use, first unpack the package, lubricate the patient’s end 1, and insert it into the urethra until it reaches the bladder. At this time, the insertion resistance suddenly loses. Observe that the patient’s urine flows out of the tube body 3, and then insert 3 to 4 cm. Use without a needle Use a sterile syringe to inject rated sterile water into the balloon 5 through the one-way valve 43, and then gently pull the tube body 3 outwards so that the expanded balloon 5 blocks the bladder to perform catheterization. The application can be adapted to various patients by adjusting the sterile water injected.

When using a disposable urinary catheter with a flushing end 6, after the expanded balloon 5 blocks the bladder and catheterizes the bladder, an appropriate amount of flushing fluid is injected from the flushing cavity to flush the bladder and then discharged through the urination end 2.

In summary, the utility model has the advantages of:

The disposable urinary catheter of this application has a reasonable product structure. In terms of use, the catheter is suitable for different patients through the design of the balloon and the water injection cavity. Cross-infection, while reducing the cost, improves the comfort of use.
