Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to a clinical catheter assembly device for urology. Background Art

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC) and can be inserted into the bladder through the urethra to drain urine. After the urinary catheter is inserted into the bladder, there is an air bag near the head of the catheter to fix the catheter in the bladder and prevent it from coming out. The drainage tube is connected to a urine bag to collect urine. Existing urine bags have measuring lines on them, which are mainly used to measure the urine in the patient's bladder. However, the urine bag is only hung by the bedside and is not convenient to carry. Sometimes, doctors need to test the patient's urine, and it is not convenient to extract urine.

[0003] In response to the above problems, a Chinese patent (patent publication number: CN213284721U) discloses a urology clinical catheter assembly device, including a urine collecting box and a three-lumen urinary catheter, the upper surface of the urine collecting box is fixedly connected to a urine inlet tube, the internal thread of the urine inlet tube is connected to a connecting ring, the top of the connecting ring is fixedly connected to a ureteral hose, the end of the ureteral hose away from the connecting ring is fixedly connected to the urination end of the three-lumen urinary catheter, the two sides of the urine collecting box are respectively fixedly connected to a first strap and a second strap, the sides of the urine collecting box are respectively fixedly connected to a battery box and a control box, the inner wall of the urine collecting box is fixedly connected to a partition, and the lower surface of the partition is fixedly connected to a sampling tube.

[0004] Although the above technical solution facilitates the carrying of the urine collection box by providing the first strap, the second strap, the Velcro sub-strip and the Velcro mother-strip, and also provides a sampling tube, a solenoid valve, a conical leakage tube and a sampling test tube, it is convenient to extract the urine to be tested. However, the urine extraction process of the device is complicated, and the patient may not be able to operate it by himself, resulting in the problem of poor practicality. Therefore, there is an urgent need for a device that allows patients to extract urine by themselves. Summary of the invention

[0005] The present invention aims to provide a urology clinical catheter assembly device, which solves the problem that the existing urinary catheter assembly device cannot enable the patient to extract urine by himself.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a technical solution as follows: a urology clinical catheter assembly device, comprising a urine collecting box with a strap, the top of the urine collecting box is connected to a three-lumen catheter, the bottom of the urine collecting box is penetrated by a threaded hole, a fixing ring is provided in the threaded hole, a conical hole is opened in the fixing ring, a sealing block with one end located outside the conical hole is provided in the conical hole, the upper side of the sealing block closes the upper side of the conical hole, a sampling tube is threadedly connected in the threaded hole, and the sealing block is located on the movement trajectory of the sampling tube.

[0007] Furthermore, a sliding ring is connected to the sealing block, the sliding ring is located on the movement track of the sampling tube, and a spring is connected between the sliding ring and the fixed ring.

[0008] Through the above arrangement, after the urine extraction is completed, the sealing block can be quickly reset with the help of the elastic force of the spring, and the conical hole can be closed again, thereby completing the urine extraction and improving the accuracy of urine extraction.

[0009] Furthermore, a slide groove is provided in the sampling tube, a slide column is slidably connected in the slide groove, a shielding plate is rotatably connected to the slide column, and a torsion spring is connected between the shielding plate and the slide column.

[0010] Through the above-mentioned setting, the baffle plate can be used to cover the mouth of the sampling tube after urine extraction, which is helpful to prevent urine from swaying and overflowing in the sampling tube and causing environmental pollution. At the same time, it can also reduce the transmission of odor in the sampling tube, further reducing pollution to the environment.

[0011] Furthermore, the diameter of the shielding plate is slightly smaller than the inner diameter of the sampling tube.

[0012] Through the above arrangement, the tube opening of the sampling tube can be shielded as much as possible without affecting the rotation of the shielding plate, which is helpful to prevent environmental pollution.

[0013] Furthermore, the thickness of the right side of the shielding plate is greater than the thickness of the left side, and the left bottom of the shielding plate is higher than the right bottom.

[0014] Through the above arrangement, the shielding plate can be tilted slightly by utilizing the buoyancy generated by urine on the shielding plate, thereby facilitating the maintenance of the urine inflow and outflow rate.

[0015] Furthermore, the positions of the slide column and the slide groove are close to the right side wall of the sampling tube, and the shielding plate remains horizontal when the torsion spring does not generate torsion.

[0016] Through the above-mentioned arrangement, the sliding column is eccentrically arranged on the baffle plate, which is beneficial for rotating the baffle plate with the help of the gravity of urine when urine is extracted. At the same time, the baffle plate can also be kept horizontal when urine is not extracted, which is beneficial for extending the service life of the torsion spring and avoiding the sampling tube from being unable to be used normally due to long storage time.

[0017] Furthermore, the urine collecting box is connected with a drainage pipe, and a valve is installed on the drainage pipe.

[0018] Through the above arrangement, the excess urine can be easily discharged with the help of the valve, thereby realizing continuous catheterization.

[0019] Compared with the prior art, this solution has the following beneficial effects:

[0020] 1. This solution has a simple structure and is easy to operate. It is conducive to the promotion and application of hospitals. It can meet the needs of urine extraction and testing, and can also reduce the patient's dependence on medical staff or family members, greatly improving the convenience of the device. And after urine extraction, a new sampling tube can be replaced, which is conducive to reducing the number of insertions and withdrawals of the three-lumen catheter, alleviating the pain of patients, and saving related consumables. It can also reduce costs and realize continuous catheterization.

[0021] 2. This solution can reduce urine spillage or odor diffusion during urine extraction and transportation, which is helpful to avoid environmental pollution and improve patient satisfaction with hospitalization. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described in detail below through specific embodiments:

[0026] The reference numerals in the drawings of the specification include: a binding band 1, a urine collecting box 2, a drainage tube 3, a valve 4, a three-chamber urinary catheter 5, a hose 6, a fixing ring 7, a sealing block 8, a connecting rod 9, a sliding ring 10, a spring 11, a sampling tube 12, a slide groove 13, a sliding column 14, and a baffle 15.

[0027] Example

[0028] As attached Figures 1 to 3As shown: a urology clinical catheter assembly device, including a urine collection box 2 with a strap 1, the number of straps 1 is two, the two straps 1 are respectively fixedly connected to the upper part of the left and right sides of the urine collection box 2, and the urine collection box 2 can be fixed on the patient's body with the help of the two straps 1, so that the urine collection box 2 is easy to carry. An observation window is embedded in the front side of the urine collection box 2, and the observation window is engraved with scale lines. The urine volume in the urine collection box 2 can be observed through the scale lines. A drainage pipe 3 is connected to the right side wall of the urine collection box 2, and a valve 4 is installed on the drainage pipe 3. The drainage of urine can be achieved by means of the drainage pipe 3 and the valve 4. A three-lumen urinary catheter 5 is connected to the top of the urine collection box 2, and the three-lumen urinary catheter 5 is connected to the urine collection box 2 through a hose 6. A threaded hole is penetrated at the bottom of the urine collection box 2, and a fixing ring 7 is threadedly connected to the upper side of the threaded hole. A conical hole is penetrated in the middle of the fixing ring 7, and the diameter of the top of the conical hole is greater than the diameter of the bottom of the conical hole. A sealing block 8 with its lower end located at the lower side of the conical hole is slidably connected in the conical hole. The upper side of the sealing block 8 closes the upper side of the conical hole. At this time, the upper surface of the sealing block 8 is flush with the upper surface of the fixing ring 7. The lower side of the sealing block 8 is also fixedly connected with symmetrically arranged connecting rods 9. The bottoms of the two connecting rods 9 are commonly connected with a sliding ring 10. The sliding ring 10 and the screw can maintain the inner wall of the perforation of the sealing block 8 by means of a spring 11. The sliding ring 10 is located on the motion trajectory of the sampling tube 12. Two springs 11 are also connected between the sliding ring 10 and the fixing ring 7. The two springs 11 are symmetrically arranged on the left and right sides of the sliding ring 10.

[0029] The lower side of the threaded hole is threadedly connected with a sampling tube 12. The inner walls of the front and rear sides of the sampling tube 12 are provided with symmetrically arranged sliding grooves 13. The two sliding grooves 13 are slidably connected with a sliding column 14. A shielding plate 15 is rotatably connected to the sliding column 14. A torsion spring is connected between the shielding plate 15 and the sliding column 14. When the torsion spring does not generate torsion, the shielding plate 15 remains horizontal. The sliding column 14 and the sliding groove 13 are located close to the right side wall of the sampling tube 12. The sliding column 14 is eccentrically arranged on the shielding plate 15, which is more conducive to uneven distribution of gravity on both sides of the sliding column 14 on the shielding plate 15, so that the shielding plate 15 rotates under the gravity of urine to achieve urine extraction. The diameter of the shielding plate 15 is slightly smaller than the inner diameter of the sampling tube 12; the thickness of the right side of the shielding plate 15 is greater than that of the left side, and the bottom of the left side of the shielding plate 15 is higher than the bottom of the right side.

[0030] The working process of this embodiment:

[0031] First, insert the three-chamber urinary catheter 5 into the patient's bladder, and the urine in the bladder flows into the urine collection box 2 along the hose 6. When the urine in the bladder is drained, the amount of urine in the patient's bladder can be measured by the scale line. If it is necessary to sample and test the urine, the patient can rotate the sampling tube 12 upward by himself, and the sampling tube 12 moves upward. When the sampling tube 12 is against the sliding ring 10, the sampling tube 12 can push the sliding ring 10, the connecting rod 9 and the sealing block 8 to move upward. After the side wall of the sealing block 8 is separated from the side wall of the conical hole, the urine in the urine collection box 2 flows into the sampling tube 12 through the gap between the sealing block 8 and the conical hole. The speed of the flow rate can be adjusted by the height of the slider lifted by the sampling tube 12, and the patient can also adjust the flow rate by himself, thereby speeding up the efficiency of urine extraction.

[0032] After the urine enters the sampling tube 12, the urine slides onto the shielding plate 15, causing the shielding plates 15 on both sides of the sliding column 14 to rotate due to uneven force. At this time, the urine will slide along the surface of the shielding plate 15 to the space of the sampling tube 12 under the shielding plate 15, thereby realizing the extraction of urine. When the amount of urine extracted gradually increases, the right side of the bottom of the shielding plate 15 will generate buoyancy under the action of urine, causing the shielding plate 15 to have a certain tilt, thereby improving the extraction efficiency of urine. At this time, the shielding plate 15 can shield most areas of the urine extracted from the sampling tube 12, avoiding the problem of urine overflowing due to the shaking of the sampling tube 12 and the urine collecting box 2, and reducing environmental pollution. After the urine in the sampling tube 12 is collected, the sampling tube 12 is quickly separated from the sliding ring 10, and the sliding ring 10 and the sealing block 8 will quickly reset under the action of the spring 11, thereby closing the conical hole again, thereby improving the accuracy of the sampling amount. At this time, the sampling tube 12 can be taken out to test the extracted urine, which is simple and convenient to operate and is conducive to improving the extraction efficiency. Then a new sampling tube 12 can be replaced to sample again, which is conducive to maintaining the continuity of the use of the device, and can also extend the service life of the urine collection box 2 and the three-lumen urinary catheter 5. There is no need to remove the three-lumen urinary catheter 5, which reduces the frequency of connecting or removing the three-lumen urinary catheter 5 for the patient, and is conducive to improving the comfort of the patient.

[0033] When the patient needs to move, the two straps 1 are wrapped around the patient's waist. When the urine is full, the drainage pipe 3 and the valve 4 can be opened to discharge the urine. By using the urology clinical catheter assembly device, the flexibility of the urine collection box 2 is improved, and urine sampling during urine testing is also convenient.

[0034] The above are only embodiments of the present invention, and the common knowledge such as the known specific structures and / or characteristics in the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
