Description

Technical Field

[0001] The present invention relates to the technical field related to catheter detection, and specifically to a catheter leak prevention detection device. Background Art

[0002] A catheter is a medical supply, mainly used to help patients who cannot urinate independently drain urine. Its main function is to help people with difficulty urinating urinate normally. It is also used for surgical preparation, emptying urine during surgery to avoid accidental injury to the bladder, and for bladder treatment, facilitating medical staff to accurately record the urine volume of patients. Applicable situations include patients with urinary retention or bladder outlet obstruction, urinary incontinence patients, patients who need to accurately monitor urine volume, situations where patients cannot or are unwilling to collect urine, patients who need to stay in bed for a long time or are in a forced position, and perioperative use during surgery. In the existing market, after the catheter is produced, it needs to be detected by a detection device. The most common is to detect it through a sealing detection device to avoid leakage of the catheter and affect normal use. The existing sealing detection devices on the market, when detecting, inject air into the catheter body through an air pump inside the detection main body and a connecting air pipe to increase the air pressure inside the catheter body, and detect the air pressure change inside the constant pressure chamber through a pressure sensor to judge the sealing condition of the catheter body;

[0003] After retrieval, a sealing detection device with a flipping structure for catheter processing, with the application number 202110100090.1, relates to the technical field of catheter processing, 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. Water storage tanks are fixed on both sides above the bearing platform, and a water pump is installed above the water storage tanks. One side of the water pump close to the detection water tank is connected with a water pipe. The beneficial effect of the present invention is that the device is provided with a flipping mechanism. Through the rotating motor and the rotating shaft, it is convenient to drive the rotation of the flipping plate and the fixing frame. The two flipping plates and the fixing frame are of an integrated structure, so as to facilitate the flipping of the two groups of first sealing and fixing mechanisms and the second sealing and fixing mechanisms on the upper and lower sides and the catheter body arranged therebetween, making the use more flexible, and the catheter bodies on the upper and lower sides are alternately flipped for detection, which can improve the detection efficiency;

[0004] However, when the above-mentioned devices are used for detection, the water injection port and medicine injection port of the catheter need to be connected to the external trachea. However, since the diameters of the liquid injection port and water injection port of the catheter are relatively small, and in order to ensure the sealing performance of the water injection port and medicine injection port later, the sizes of the external clamping trachea heads are set to correspond to the sizes of the liquid injection port and water injection port. As a result, when manually clamping the water injection port and medicine injection port of the catheter, it is often very difficult to perform the installation clamping and subsequent disassembly work, which will affect the detection efficiency of the entire device. Summary of the Invention

[0005] The purpose of the present invention is to provide a leak-proof detection device for catheters to solve the problem proposed in the above background technology that when the current devices on the market are used for detection, the water injection port and medicine injection port of the catheter need to be connected to the external trachea.

When clamping the catheter, first, only need to control the driving mechanism to pull the bottom of the internal fixing mechanism downward, thereby reducing the diameter size of the entire internal fixing mechanism. Thus, at this time, the staff can easily perform the quick clamping work on the water injection port and the medicine injection port on the catheter. After the clamping is completed, control the driving mechanism to work in the reverse direction, which will cause the entire internal fixing mechanism to reset upward and its overall volume to increase. Furthermore, it can squeeze the inner sides of the water injection port and the medicine injection port, achieving the effect of internal extrusion and fixation. At the same time, the symmetric clamping blocks on the external fixing mechanism will move towards each other to perform the clamping and fixing work on the outside of the water injection port and the medicine injection port of the catheter again. Thus, it ensures that the installation of the bottom of the entire catheter is very convenient, and there will be no phenomenon of incomplete clamping. Also, when disassembling later, when controlling the clamping blocks on the external fixing mechanism to separate from each other, it will again reduce the overall volume of the internal fixing mechanism, making the subsequent disassembly work very convenient. Therefore, it ensures that the manual installation efficiency is increased, and further improves the detection efficiency of the entire device.

[0028] (2) When the clamping assembly clamps, it moves towards each other and clamps through the inflatable columns inside the installation frame. By the mutual clamping of the cylindrical inflatable columns, it will not cause excessive extrusion pressure on the top of the liquid inlet of the catheter, and thus will not affect the subsequent normal operation of the catheter.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0047] Please refer to Figures 1-12 , the present invention provides a technical solution: a catheter leak prevention detection device, including a fixed bottom plate 1, which is arranged in a plate-like structure and installed at the bottom of the entire device for supporting the entire device;

[0048] A lower box body 2, which is installed at the top of the fixed bottom plate 1, and a support seat 3 is integrally installed at the top of one side thereof. A lifting mechanism 5 is arranged inside the support seat 3 and is connected to the upper box body 4;

[0049] It also includes;

[0050] A fixing mechanism, which is arranged inside the lower box body 2 and is provided outside both of the two clamping tubes 7. The fixing mechanism includes an inner fixing mechanism 6 and an outer fixing mechanism 12. The clamping tube 7 is arranged inside the inner fixing mechanism 6, and the outer fixing mechanism 12 is arranged outside the inner fixing mechanism 6. A connecting tube 9 that penetrates through it is arranged at the bottom of the clamping tube 7, and the bottom of the connecting tube 9 is connected to the detection main body 10. The air injection and pressure detection work are completed through the detection main body 10;

[0051] The internal fixing mechanism 6 is used to squeeze and seal the inner sides of the water injection port and the medicine injection port of the catheter. The external fixing mechanism 12 is used to squeeze and fix the outer sides of the water injection port and the medicine injection port clamped on the internal fixing mechanism 6. And the internal fixing mechanism 6 is a movable structure, which can be enlarged and reduced to achieve the effect of facilitating the clamping of the water injection port and the medicine injection port.

[0052] This application provides a leak-proof detection device for a catheter that can be clamped and fixed inside and outside. Specifically, when in use, first, the entire device is installed in a suitable position under the action of the fixed bottom plate 1. After that, the water injection end and the medicine injection end of the catheter to be detected are respectively clamped with the outer sides of the internal fixing mechanism 6 outside the two clamping tubes 7. The inner clamping work of the water injection end and the medicine injection end of the catheter is completed through the external fixing mechanism 12. Then, under the action of the external fixing mechanism 12, the outer sides of the water injection end and the medicine injection end of the catheter are fixed to complete the internal and external fixing work. After that, the staff holds the top of the guide tube and works vertically upward. Then, under the action of the lifting mechanism 5, the upper box body 4 is controlled to descend, and the position of the liquid inlet of the top end of the catheter is clamped and sealed through the upper box body 4. Then, the detection main body 10 inside the lower box body 2 is started, and the air pump inside it is used to inflate the entire catheter. After a period of time, with the setting of the gas pressure sensor inside the constant pressure box inside it, the gas pressure can be detected to complete the airtightness detection work.

[0053] Among them, according to Figure 1 As shown, a fixed cover 15 is also provided at the position slightly outside the top end of the lower box body 2, and its inner side penetrates through the inner hollow structure of the lower box body 2;

[0054] Specifically, the setting of the fixed cover 15 can achieve the effect of facilitating the staff to quickly observe by setting a display screen electrically connected to the gas pressure sensor on its outside, and its inner hollow structure is used to protect the top end of the protruding external fixing mechanism 12.

[0055] As a further preference of this embodiment, when controlling the up and down movement of the entire upper box body 4, according to Figure 9 and Figure 10 As shown, a connecting sleeve 41 and two sliders 42 are respectively provided on the back of the upper box body 4. The two sliders 42 are symmetrically arranged about the central axis of the connecting sleeve 41, and through holes penetrate through the middle of the connecting sleeve 41 and the sliders 42. And a threaded structure is provided on the inner wall of the through hole inside the connecting sleeve 41. 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.

[0056] The lifting mechanism 5 is arranged in the internal hollow structure of the support base 3, and it includes a moving lead screw 51 and two limiting rods 53. The two limiting rods 53 are symmetrically arranged with respect to the central axis of the moving lead screw 51, and the top end of the moving lead screw 51 penetrates through the outer wall of the support base 3 and is connected to the rotating motor 52;

[0057] The moving lead screw 51 penetrates through the inside of the connecting sleeve 41 and meshes with the threaded structure of the inner perforation of the connecting sleeve 41. The outer side of the limiting rod 53 has a smooth surface and penetrates through the perforation inside the slider 42. The top ends of the moving lead screw 51 and the limiting rod 53 both penetrate through the sliding groove on the inner surface of the support base 3, and both move up and down in the sliding groove;

[0058] Specifically, it is necessary to start the rotating motor 52 at the top of the support base 3 to drive the moving lead screw 51 at its bottom to rotate. When the moving lead screw 51 rotates, it will be threadedly connected to the threaded structure in the inner perforation of the connecting sleeve 41 on the back of the upper box body 4, so that the upper box body 4 moves up and down with the connecting sleeve 41;

[0059] When the upper box body 4 moves up and down, since the slider 42 will also move up and down, and in cooperation with the penetration between the perforation inside the slider 42 and the limiting rod 53, the limiting work of the upper box body 4 can be completed, and thus the effect of controlling the up and down movement of the upper box body 4 can be achieved.

[0060] In this application, according to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 shown, both the internal fixing mechanism 6 and the external fixing mechanism 12 are driven and controlled by the driving mechanism 11. The internal fixing mechanism 6 includes a moving seat 61, a connecting component 62 and a clamping block 63. The inner side of the moving seat 61 is provided with a threaded structure for threaded connection with the outside of the clamping tube 7, and a limiting block is arranged on the outside of the moving seat 61 to slide in the limiting groove inside the lower box body 2;

[0061] The connecting components 62 are connected to the clamping block 63 in an equiangular distribution at the top end of the moving seat 61, and the connecting component 62 can be any one of a cable or a cord. The clamping block 63 is made of rubber, and its top end is provided with a conical structure, and the inner side of the clamping block 63 is heat-melt connected to the outside of the clamping tube 7;

[0062] The bottom of the clamping tube 7 is coaxially connected with a meshing gear 8, and the connecting tube 9 at the bottom of the clamping tube 7 is made of metal. The top end of the connecting tube 9 is provided with a fixing cover which is connected to the bottom of the clamping tube 7 by a bearing, and the outside of the meshing gear 8 is driven and controlled by the driving mechanism 11;

[0063] Specifically, when the driving mechanism 11 works, it will cause the engaging tube 7 at its top to rotate. When the engaging tube 7 rotates, it will be threadedly connected to the moving seat 61 on its outer side. Thus, the moving seat 61 moves up and down under the limiting action of the limiting block. When the moving seat 61 moves up and down, since the top of the connecting component 62 is connected to the bottom of the engaging block 63 made of rubber material, the moving seat 61 will cause the connecting component 62 to pull the bottom of the entire engaging block 63 downward. As a result, the outer side of the entire engaging block 63 will deform and become smaller, thus ensuring more convenient connection and engagement with the catheter.

[0064] Among them, according to Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, the driving mechanism 11 includes a driving motor 111, a driving gear 112 and a worm 113. The top of the driving motor 111 is coaxially connected to the driving gear 112, and the top of the driving gear 112 is coaxially connected to the worm 113;

[0065] The outer side of the driving gear 112 meshes with the meshing gears 8 at the tops of the two engaging tubes 7, and the driving gear 112 and the two meshing gears 8 are distributed in a triangle;

[0066] On the outer side of the worm 113, two outer fixing mechanisms 12 are symmetrically arranged to clamp and fix the outside of the catheter clamped by the two engaging tubes 7;

[0067] When the driving mechanism 11 works, it is necessary to start the driving motor 111 to drive the driving gear 112 at its top to rotate. Thus, the driving gear 112 meshes with the meshing gear 8 on its outer side, and the meshing gear 8 starts to rotate;

[0068] When the driving gear 112 rotates, it will cause the worm 113 coaxially connected to it to rotate, and thus drive the outer fixing mechanism 12 to perform the clamping and fixing work.

[0069] Furthermore, according to Figure 7 shown, the outer fixing mechanism 12 includes a rotating gear disk 121, a bidirectional lead screw 122, a connecting seat 123 and a clamping block 124. The rotating gear disk 121 is arranged on the outer side of the worm 113 and meshes with the worm 113. The top of the rotating gear disk 121 is coaxially connected to the bidirectional lead screw 122. On the outer side of the bidirectional lead screw 122, two connecting seats 123 are symmetrically arranged, and the connecting seats 123 are threadedly connected to the bidirectional lead screw 122. The top of the connecting seat 123 is also integrally installed with the clamping block 124;

[0070] A limiting block is integrally installed on the outer side of the connecting seat 123 to perform sliding limiting work in the limiting groove inside the lower box body 2;

[0071] Among them, when the worm 113 rotates, it can cause the rotating gear disk 121 to rotate. Thus, the rotating gear disk 121 drives the bidirectional lead screw 122 to rotate. As a result, the bidirectional lead screw 122 meshes with the connecting seat 123, and then the connecting seat 123 drives the clamping blocks 124 at its top to move towards and away from each other, completing the effects of clamping and loosening.

[0072] As a further preferred embodiment of this example, according to Figure 8 As shown, an air venting component 13 is provided between the engaging pipe 7 and the internal fixing mechanism 6, and the air venting component 13 includes a first air passage 131 and a second air passage 132. The first air passage 131 is provided inside the engaging block 63, and the first air passage 131 and the second air passage 132 penetrate each other. The second air passage 132 is provided inside the engaging pipe 7, and the bottom of the second air passage 132 penetrates the top of the connecting pipe 9;

[0073] Specifically, when inflating, the air pump inside the detection main body 10 needs to fill the inside of the urinary catheter through the connecting pipe 9, the first air passage 131 and the second air passage 132 on one side. After a period of time, when the gas entering the urinary catheter is full, it reaches the constant pressure box inside the detection main body 10 through another connecting pipe 9. Cooperating with the gas pressure sensor inside it, the pressure change inside can be observed, and thus the effect of air pressure detection is achieved, thereby completing the airtightness detection work.

[0074] As a further preferred embodiment of this example, according to Figure 11 and Figure 12 As shown, the clamping mechanism 14 includes a control motor 141, a rotating lead screw 142, a sliding seat 143 and a clamping component 144. The top of the control motor 141 is coaxially connected with the rotating lead screw 142, and the rotating lead screw 142 is provided with a symmetrical threaded structure, and sliding seats 143 are threadedly connected to the outside of its symmetrical threaded structure. The bottom of the sliding seat 143 is provided with a clamping component 144;

[0075] The clamping component 144 includes a mounting frame 1441 and an inflatable column 1442. The top of the mounting frame 1441 is mounted on the bottom of the sliding seat 143, and its overall is arranged in a semi-circular arc structure. The inside of the mounting frame 1441 is provided with a cylindrical inflatable column 1442;

[0076] Specifically, when clamping the liquid inlet position at the top end of the catheter, it is necessary to start the control motor 141 to drive the rotating lead screw 142 at its top end to rotate. When the rotating lead screw 142 rotates, the symmetric thread structures on its outer part mesh with the sliding seats 143, causing the two symmetric sliding seats 143 to move towards and away from each other, thereby driving the clamping assembly 144 at its bottom to move. When the clamping assembly 144 moves towards each other, due to the arrangement of the inflatable column 1442 inside it, it can clamp and seal the top end of the catheter to ensure that there is no leakage at its top end.
