Description

Technical Field

[0001] The invention relates to the technical field related to urinary catheter detection, and in particular to a urinary catheter leakage prevention detection device. Background Art

[0002] A urinary catheter is a medical product that is mainly used to help patients who cannot urinate on their own to drain urine. Its main function is to help people with urination difficulties to urinate normally. It is also used in surgical preparation, emptying urine during surgery to avoid accidental injury to the bladder, and for bladder treatment, so that medical staff can accurately record the patient's urine volume. Applicable situations include patients with urinary retention or bladder outlet obstruction, patients with urinary incontinence, patients who need to accurately monitor urine volume, patients who cannot or are unwilling to collect urine, patients who need to stay in bed for a long time or are forced to stay in a certain position, and perioperative use during surgical operations. In the existing market, after the production of urinary catheters is completed, they need to be tested by testing equipment. The most common is that they need to be tested by sealing testing equipment to avoid leakage of the urinary catheter and affect normal use. The sealing testing equipment on the existing market, when testing, injects air into the catheter body through the air pump inside the detection body and the connecting trachea to increase the air pressure inside the catheter body, and detects the air pressure change inside the constant pressure chamber through the air pressure sensor, so as to judge the sealing condition of the catheter body; After searching, the application number is 202110100090.1. A sealing detection device with a flipping structure for catheter processing relates to the field of catheter processing technology, including a base, a detection water tank and a flipping mechanism. A bearing platform is fixed above the middle of the base, and a waterproof pad is arranged above the bearing platform. The detection water tank is installed above the waterproof pad, and water storage tanks are fixed on both sides above the bearing platform, and a water pump is installed above the water storage tank. The side of the detection water tank close to the water pump is connected to a water pipe. The beneficial effect of the present invention is that the device is provided with a flipping mechanism, which is convenient for driving the rotation of the flipping plate and the fixed frame by a rotating motor and a rotating shaft. The two flipping plates and the fixed frame are an integrated structure, so as to facilitate the flipping of the two groups of first sealing fixing mechanisms and second sealing fixing mechanisms on the upper and lower sides and the catheter body arranged therebetween, which is more flexible to use, and the detection efficiency can be improved by flipping the catheter bodies on the upper and lower sides in turn; However, when the above-mentioned equipment is being tested, it is necessary to connect the water injection port and the drug injection port of the catheter with the external trachea. However, since the diameters of the liquid injection port and the water injection port of the catheter are relatively small, in order to ensure the sealing of the water injection port and the drug injection port, the size of the external engaging trachea head is set to correspond to the size of the liquid injection port and the water injection port. As a result, when the water injection port and the drug injection port of the catheter are manually engaged, the installation engagement and subsequent disassembly work are often very difficult, which affects the detection efficiency of the entire equipment. Summary of the invention

Specifically, when using it, first, the whole device is installed in a suitable position under the action of a fixed bottom plate 1, and then the water injection end and the drug injection end of the catheter to be detected are clamped with the outer side of the internal fixing mechanism 6 outside the two clamping tubes 7 respectively, and the inner side clamping work of the water injection end and the drug injection end of the catheter is completed by the external fixing mechanism 12. Then, under the action of the external fixing mechanism 12, the outer side of the water injection end and the drug injection end of the catheter is fixed. After completing the internal and external fixing work, the staff takes the top of the guide tube and works vertically upwards. Then, the upper box body 4 is controlled to descend under the action of the lifting mechanism 5, and the position of the liquid inlet at the top of the catheter is clamped and sealed through the upper box body 4. Then, the detection body 10 inside the lower box body 2 is started, so that the air pump inside it inflates the interior of the entire catheter. After a period of time, the gas pressure can be tested in conjunction with the setting of the gas pressure sensor inside the constant pressure box to complete the sealing test.

[0033] Among them, according to Figure 1 As shown, a fixed cover 15 is also provided at the outer side of the top of the lower box body 2, and the inner side of the fixed cover 15 penetrates the inner hollow structure of the lower box body 2; Specifically, the setting of the fixed cover 15 can achieve the effect of facilitating quick observation by the staff by setting a display screen electrically connected to the gas pressure sensor on its outside, while the hollow structure inside it is used to protect the top of the protruding external fixing mechanism 12.

[0034] As a further preferred embodiment of the present invention, when controlling the entire upper box body 4 to move up and down, according to Fig. 9 and Fig.10As shown, a connecting sleeve 41 and two sliders 42 are respectively provided on the back of the upper box body 4, and the two sliders 42 are symmetrically arranged about the central axis of the connecting sleeve 41, and the middle of the connecting sleeve 41 and the slider 42 are penetrated by perforations, and a threaded structure is arranged on the inner wall of the perforation on the inner side of the connecting sleeve 41, and a clamping mechanism 14 is also provided at the bottom of the upper box body 4 for clamping and sealing the liquid inlet end of the catheter.

The top ends of the movable screw rod 51 and the limiting rod 53 both pass through the slide groove on the inner surface of the support seat 3, and both move up and down in the slide groove. Specifically, it is necessary to start the rotating motor 52 at the top of the support seat 3 so that it drives the moving screw 51 at the bottom thereof to rotate. When the moving screw 51 rotates, it will be threadedly connected with the thread structure in the internal perforation of the connecting sleeve 41 on the back of the upper box body 4, thereby making the upper box body 4 move up and down with the connecting sleeve 41; When the upper box body 4 moves up and down, the slider 42 will also move up and down. The penetration between the perforation inside the slider 42 and the limiting rod 53 can complete the limiting work of the upper box body 4, thereby achieving the effect of controlling the upper box body 4 to move up and down.

After a period of time, the gas entering the catheter is filled and passes through another connecting tube 9 to reach the constant pressure box inside the detection body 10. In conjunction with the gas pressure sensor inside it, the internal pressure changes can be observed, thereby achieving the effect of air pressure detection, thereby completing the air tightness detection work.

A cylindrical inflatable column 1442 is arranged on the inner side of the mounting frame 1441. Specifically, when clamping the top liquid inlet position of the catheter, it is necessary to start the control motor 141 so that it drives the rotating screw 142 at the top to rotate. When the rotating screw 142 rotates, its external symmetrical threaded structure engages with the sliding seat 143, so that the two symmetrical sliding seats 143 move toward and opposite to each other, thereby driving the clamping assembly 144 at the bottom to move.
