Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, in particular to a disposable urinary catheter with the function of urine sample collection. Background Technique

[0002] In the clinical nursing of obstetrics, during the waiting period of pregnant women, due to reasons such as tension, labor analgesia, and prolonged second stage of labor, bladder distension and inability to urinate spontaneously are relatively common. When using traditional disposable urinary catheterization, urine collectors such as bedpans need to be prepared. If the operation is improper, urine is likely to leak out, contaminating the bed sheet and the patient's clothes. At the same time, it is also difficult to collect clean urine for the parturient due to lochia after childbirth, affecting laboratory tests, etc. Sampling through a urinary catheter can be more convenient. For example, the Chinese utility model patent with the authorization publication number CN215461272U discloses a urinary catheter, including a urinary catheter and a liquid collection bottle. The front end of the urinary catheter is provided with a front port. Both side walls at the bottom end of the front port of the urinary catheter are provided with side openings. Below the two side openings of the urinary catheter, there is a balloon. The balloon is connected with two connecting pipes attached to the outer wall of the urinary catheter. The tail ends of the connecting pipes are connected to the injection pipe. A clamping device is arranged between the position of the urinary catheter near the bottom end and the liquid collection bottle. This type of urinary catheter is the same as a conventional urinary catheter. If it is necessary to collect the urine of pregnant and lying-in women, a collector is placed at the outlet of the urinary catheter. When the pregnant and lying-in woman urinates, the medical staff beside needs to stabilize the collector. Otherwise, it may be knocked over because of the movement of the pregnant and lying-in woman's body, and the operation is not convenient. When sampling urine, usually the middle urine is taken, and this collection method is not convenient for collection. Content of the Utility Model

[0003] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a disposable urinary catheter with the function of urine sample collection.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A disposable urinary catheter with the function of urine sample collection, including a urinary catheter main body, a thick tube part is arranged on the urinary catheter main body, the thick tube part is communicated with the urinary catheter main body, a short tube part is fixedly communicated with the thick tube part, a plastic sealing block is hermetically and fixedly arranged in the short tube part, a sampling tube is arranged on the side of the short tube part away from the thick tube part, the opening of the sampling tube is threadedly connected with a sealing cover, a thin needle part is coaxially communicated with the sealing cover, an annular part is sleeved outside the thin needle part, the annular part is slidably sleeved on the sealing cover, an elastic limiting component is arranged between the sealing cover and the annular part, and a matching thread structure is arranged between the annular part and the short tube part.

[0006] Preferably, the elastic limiting component includes an annular protrusion fixedly arranged in the opening of the annular part, and the annular protrusion is connected with the sealing cover through a limiting spring.

[0007] Preferably, the thick cylinder member is made of a transparent material.

[0008] Preferably, annular anti-slip protrusions are provided outside the annular member.

[0009] Preferably, a micro manual valve is fixedly provided at the liquid outlet position of the catheter main body.

[0010] Preferably, a matching plug is connected to one side of the annular member.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The device improves the disposable catheter. By providing a thick cylinder member on the catheter to provide a temporary accommodation cavity for urine, and at the same time providing a short pipe member and a plastic sealing block, sampling is carried out through an external sampling tube. When sampling, the sampling tube is pressed inward so that the thin needle member on the sealing cover inserts into the plastic sealing block, and then the urine is introduced into the sampling tube. After sampling, the sampling tube can be unscrewed. The overall use is convenient. At the same time, when sampling, the catheter drains urine and then presses the sampling tube, which can conveniently sample the middle-section urine, and the sampling effect is better.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Referring to Figures 1-3 a disposable catheter with a urine sample collection function shown, including:

[0019] Similar to the existing catheter body 1, the catheter body 1 can perform catheterization operations. In order to implement the operation of collecting urine samples, a thick tube member 2 is provided on the catheter body 1. The thick tube member 2 is communicated with the catheter body 1. A short tube member 3 is fixedly communicated with the thick tube member 2. A plastic sealing block 4 is fixedly and hermetically arranged in the short tube member 3, similar to the structure of the infusion port of an infusion bottle;

[0020] At the same time, a sampling tube 5 is arranged on the side of the short tube member 3 away from the thick tube member 2. The opening of the sampling tube 5 is threadedly connected with a cover 6. A thin needle member 7 is coaxially communicated with the cover 6. The plastic sealing block 4 can be punctured through the thin needle member 7 to perform catheterization operations; in order to ensure the connection, an annular member 8 is sleeved outside the thin needle member 7. The annular member 8 is slidably sleeved on the cover 6. An elastic limiting component is arranged between the cover 6 and the annular member 8. A matching thread structure is arranged between the annular member 8 and the short tube member 3. The annular member 8 can be connected to the short tube member 3. Moreover, when the sampling tube 5 is not pressed, the thin needle member 7 will not penetrate through the plastic sealing block 4. Similarly, pressing the sampling tube 5 can make the thin needle member 7 penetrate through the plastic sealing block 4 so that the urine sample enters the sampling tube 5.

[0021] Specifically, the elastic limiting component includes an annular protrusion 9 fixedly arranged in the opening of the annular member 8. The annular protrusion 9 is connected with the cover 6 through a limiting spring 10. The thin needle member 7 will not contact the plastic sealing block 4 without external force.

[0022] In some embodiments, in order to improve the use effect, the thick tube member 2 is made of a transparent material, such as medical silicone material, and the sampling effect can be increased by pressing; at the same time, annular anti-slip protrusions are arranged outside the annular member 8 to facilitate rotation; and a micro manual valve 11 is fixedly arranged at the liquid outlet position of the catheter body 1. The micro manual valve 11 can be closed during catheterization to ensure the sampling operation of the midstream urine sample.

[0023] After sampling, in order to facilitate sealing, a matching plug 12 is connected to one side of the annular member 8. The plug 12 does not affect the connection between the annular member 8 and the short tube member 3.

[0024] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
