Description

Technical Field

[0001] This invention relates to the field of catheterization kit technology, specifically to a catheterization kit for preventing urinary salt deposition and its method of use. Background Technology

[0002] Urinary catheterization is one of the most commonly used basic procedures in clinical diagnosis and treatment. It is widely used in scenarios such as urinary retention, difficulty in urination, pre- and post-operative urinary drainage, and urine output monitoring in critically ill patients. In order to meet the requirements of aseptic operation and clinical convenience, disposable urinary catheterization kits have been developed and widely used. These products pre-assemble, sterilize, and package components such as urinary catheters, drainage bags, sterile cotton balls, lubricants, gloves, treatment towels, square trays, and waist trays in the same package.

[0003] In current disposable urinary catheterization kits, the outer packaging is usually only used as a temporary container. After opening, it is discarded or placed randomly, lacking a direct connection structure with fixed objects such as the bed. In clinical practice, in order to fix the main body of the urinary catheterization kit or drainage bag in a suitable position at the edge of the bed, medical staff often need to use auxiliary tools such as tape, clips, or straps to temporarily fix it by manually wrapping, clamping, or binding. This process is not only cumbersome and time-consuming, but also has poor fixation reliability. It is easy for the patient's position to change, the tube to be pulled, or the tape to be not sticky enough, which can cause displacement or loosening, thus affecting the drainage effect and even increasing the risk of unplanned tube removal and contamination. Summary of the Invention

[0004] The purpose of this invention is to provide a catheterization kit for preventing urinary salt deposition and its method of use, so as to solve the problem mentioned in the background art that after using the catheterization kit, it is still necessary to manually fix the drainage bag in the kit in various ways, which is cumbersome, time-consuming and has poor fixation reliability.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A catheterization kit for preventing urinary salt deposition and its method of use, comprising a catheterization kit body, a rotating frame fixedly connected between the inner walls of the two sides of the catheterization kit body, a gear rotatably connected within the rotating frame via a rotating shaft, a placement shell and a positioning shell slidably connected within the catheterization kit body, a drainage bag disposed within the placement shell, and racks fixedly connected to the adjacent ends of the placement shell and the positioning shell, both racks meshing with the gear.

[0006] Furthermore, one end of the urinary catheterization kit body has two fixing holes, and one end of the placement shell is fixedly connected to two fixing blocks, which are respectively snapped into the two fixing holes.

[0007] Furthermore, sealing tapes are glued to both the upper and lower ends of the catheterization kit body, and traction straps are fixedly connected to both ends of the two sealing tapes.

[0008] Further, a connection hole is provided at the lower end of the sealing strip on the lower side. One end of the urine drainage bag body is fixedly connected with an adhesive. A pollution prevention strip is fitted on the surface of the adhesive. A pulling strip is fixedly connected between the lower end of the pollution prevention strip and the lower end of the placement shell. The pulling strip is slidably arranged in the connection hole.

[0009] Further, a taking groove is provided at one end of the placement shell. A sealing plate is movably hinged in the taking groove.

[0010] Further, a pulling bar is fixedly connected to the lower end of the pulling strip. The pulling bar is in a shape of a Chinese character 'hui'.

[0011] Further, two stabilizing grooves are provided on the inner walls of both sides of the urine drainage bag body. Stabilizing blocks are fixedly connected to both ends of the placement shell and the placing shell. The plurality of stabilizing blocks are respectively slidably connected in the two stabilizing grooves.

[0012] A usage method of a urine drainage bag for resisting urinary salt deposition includes the following steps: S1: When the urine drainage bag body needs to be used, first hold a plurality of traction belts, and then tear off the sealing strips pasted on the upper and lower ends of the urine drainage bag body respectively. Then pull down the pulling bar. On the one hand, through the pulling of the pulling bar, the placement shell and the drainage bag are pulled downwards. When the placement shell moves, one of the racks is synchronously driven to move, and then the meshing-connected gear is rotated, and the other rack is driven to move upwards, and the placement shell is synchronously driven to move upwards, realizing the downward movement of the placement shell and the upward movement of the placement shell. S2: When the placement shell is inside the urine drainage bag body, at this time, the sealing plate is blocked by the inside of the urine drainage bag body and cannot be unfolded through the hinge shaft. When the placement shell moves upwards to the upper side of the urine drainage bag body, at this time, the sealing plate is separated from the contact and abutment with the urine drainage bag body, and then the sealing plate naturally rotates clockwise through the shaft point, and the taking groove provided at one end of the placement shell is unfolded. Medical staff can take and use the items in the placement shell through the taking groove. S3: When the placement shell descends, the pulling strip will also descend synchronously, and gradually tear off the pollution prevention strip from the surface of the adhesive. When the placement shell descends to the maximum position, at this time, the pollution prevention strip is completely separated from the adhesive. At this time, the urine drainage bag body can be adhered to the hospital bed or other positions through the adhesive, so as to fix and stabilize the placement shell and the drainage bag inside it.

[0013] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art: 1. In use, first open both ends of the catheterization bag, then pull down the placement shell and drainage bag. Through the rack and pinion mechanism, the placement shell moves upwards to the outside of the bag, facilitating access to internal items. Simultaneously, the pull strap and anti-fouling strap move downwards, allowing you to remove the anti-fouling strap from the adhesive surface and use the adhesive to secure the catheterization bag to the bedside. This design achieves a linkage between item retrieval and automatic fixation, facilitating drainage bag fixation and preventing contamination from careless disposal of the bag, significantly improving the convenience and stability of fixation.

[0014] 2. After the placement shell moves down to its maximum distance, it can be fixed by the locking of the fixing block and the fixing hole, which improves the stability of the placement shell. The two sealing strips can seal the upper and lower ends of the urinary catheterization kit body respectively, and the two sealing strips can be easily removed by multiple traction straps.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] Example: A catheterization kit for preventing urinary salt deposition and its method of use, such as Figures 1-7 As shown, the device includes a catheterization kit body 1. A rotating frame 8 is fixedly connected between the inner walls of the two sides of the catheterization kit body 1. A gear 9 is rotatably connected inside the rotating frame 8 via a rotating shaft. A placement shell 11 and a placement shell 12 are slidably connected inside the catheterization kit body 1. A drainage bag 14 is provided inside the placement shell 11. A rack 10 is fixedly connected to the adjacent ends of the placement shell 11 and the placement shell 12. Both racks 10 mesh with the gear 9. A connection hole is provided at the lower end of the lower sealing strip 2. One end of the urinary catheter bag body 1 is fixedly connected with adhesive. An anti-fouling strip 4 is attached to the surface of the adhesive. A pull strap 5 is fixedly connected to the lower end of the anti-fouling strip 4 and the lower end of the placement shell 11. The pull strap 5 is slidably disposed in the connection hole.

[0021] In a specific embodiment of the present invention, when the catheterization kit body 1 needs to be used, the upper and lower ends of the catheterization kit body 1 are first opened, and then the placement shell 11 and the drainage bag 14 are pulled down. When the placement shell 11 moves, one of the racks 10 moves simultaneously, which in turn drives the meshing gear 9 to rotate, and the other rack 10 moves upward, simultaneously driving the placement shell 12 to move upward. This achieves the downward movement of the placement shell 11 and the upward movement of the placement shell 12. After the placement shell 12 moves to the outside of the catheterization kit body 1, the placement shell 11 can be placed... The items inside can be retrieved and used. While the housing 11 is lowered, the pull strap 5 and the anti-fouling strap 4 can also be pulled down, and the anti-fouling strap 4 can be peeled off from the adhesive surface. Then, the catheterization bag body 1 can be fixed to the side of the hospital bed through the adhesive. Through the above design, when the items are used, the catheterization bag body 1 and the drainage bag 14 can be automatically fixed to the side of the hospital bed. This not only fixes the drainage bag 14, but also prevents the catheterization bag body 1 from being discarded everywhere and causing pollution, thus improving the convenience and stability of fixing the drainage bag 14.

[0022] Preferably, the rotating shaft is an elastic rotating shaft. After the catheterization of the patient is completed, manually push the fixing block 18 away from the fixing hole 6. After they no longer cooperate, due to the pulling-back property of the elastic rotating shaft, the placement shell 11 and the placement housing 12 are pulled back into the catheterization pack body 1 again. The medical waste after catheterization can be loaded into the placement housing 12 and can be transmitted back into the catheterization pack body 1 along with the placement housing 12. Furthermore, it is convenient to discard the catheterization pack body 1 and the medical waste together into the trash can for subsequent centralized treatment. The sealing plate 13 rotates around the axis point, and the rotating shaft it uses is the same as this rotating shaft, both being elastic rotating shafts, to facilitate the natural clockwise rotation of the sealing plate 13. The clockwise rotation direction can be controlled by the selected elastic rotating shaft.

[0023] For details, please refer to Figure 1-7 , two fixing holes 6 are provided at one end of the catheterization pack body 1, and two fixing blocks 18 are fixedly connected to one end of the placement shell 11. The two fixing blocks 18 are respectively snapped into the two fixing holes 6; Sealing tapes 2 are adhesively bonded to both the upper and lower ends of the catheterization pack body 1, and traction tapes 3 are fixedly connected to both ends of the two sealing tapes 2.

[0024] In this embodiment: After the placement shell 11 moves downward to the maximum distance, the placement shell 11 can be fixed by the snap connection between the fixing block 18 and the fixing hole 6, improving the use stability of the placement shell 11. The upper and lower ends of the catheterization pack body 1 can be sealed respectively through the two sealing tapes 2, and the two sealing tapes 2 can be conveniently torn off through the multiple traction tapes 3.

[0025] For details, please refer to Figure 1-7 , a taking groove is provided at one end of the placement housing 12, and a sealing plate 13 is movably hinged in the taking groove; The lower end of the pulling belt 5 is fixedly connected to a pulling strip 7, and the pulling strip 7 is in the shape of a "return" character.

[0026] In this embodiment: When the placement housing 12 is loaded into the catheterization pack body 1, the sealing plate 13 will abut against one inner wall of the catheterization pack body 1, thereby sealing the items in the placement housing 12. When the placement housing 12 moves to the outside of the catheterization pack body 1, at this time, the sealing plate 13 rotates clockwise naturally, opening the taking groove, and thus facilitating the taking and use of the items in the placement housing 12.

[0027] For details, please refer to Figure 1-7 , two stabilizing grooves 16 are provided on both inner walls of the catheterization pack body 1, and stabilizing blocks 17 are fixedly connected to both ends of the placement housing 12 and the placement shell 11. The multiple stabilizing blocks 17 are respectively slidably connected in the two stabilizing grooves 16.

[0028] In this embodiment, when the placement shell 12 and the placement shell 11 move, multiple stabilizing blocks 17 can be driven to slide within multiple stabilizing grooves 16, thereby improving the vertical movement stability of the placement shell 12 and the placement shell 11.

[0029] Preferably, the housing 12 is equipped with a disposable anti-urinary salt deposition catheter, a drainage bag 14, a sterile medical drape, absorbent cotton balls, a disposable syringe for dispensing medication, a drape, a wrapping cloth, a small square tray, a plastic cup, a waist tray, a large square tray, gauze pads (pieces), iodine cotton balls, alcohol cotton balls, a disinfecting brush, disposable dressing forceps, plastic test tubes with caps, disposable rubber examination gloves, medical surgical gloves, cotton thread, a bed card, and lubricant for introducing instruments into the body cavity. It should be noted that the drainage bag 14 listed is the same as the drainage bag 14 mentioned in this solution, and the size of the housing 12 can be selected according to actual needs, thus facilitating the placement of the numerous listed items.

[0030] Preferably, the upper end of the drainage bag 14 is provided with a connection interface 15, which allows for easy connection between the urinary catheter and the drainage bag 14, facilitating the transfer of urine.

[0031] Preferably, the plastic gear 9 and rack 10 produced by injection molding have extremely low costs, with the price per unit controlled between 0.12 yuan and 2 yuan. The main reason is that engineering plastic raw materials such as polyoxymethylene are widely available and inexpensive. Injection molding can achieve efficient production of multiple cavities in one mold without the need for subsequent cutting processing. Moreover, the material has its own lubricity, so there is no need to add additional lubricating oil. For disposable urinary catheterization kits, the cost of gear 9 and rack 10 as a linkage component accounts for only about 0.6%-10%, which is well within the acceptable range for mass production of medical consumables and will not significantly increase the total cost of the product.

[0032] Preferably, the adhesive is a medical pressure-sensitive acrylic or silicone adhesive, applied to one end surface of the catheterization kit body 1. The lower end of the anti-fouling tape 4 is fixedly connected to the pull strap 5 by heat pressing or ultrasonic welding. The width of the connection is 5~15mm, and the connection strength is greater than the peel force between the anti-fouling tape 4 and the adhesive. The lower end of the pull strap 5 extends out of the catheterization kit body 1 and is connected to a pull bar 7. The pull bar 7 is U-shaped, which is convenient for fingers to grip and apply force. As the placement shell 11 moves downward, the pull strap 5 moves downward as well, applying a downward pulling force to the anti-fouling tape 4, so that the anti-fouling tape 4 gradually detaches from the adhesive surface at a peel angle of 15°~45°. When the placement shell 11 moves to its maximum stroke, the anti-fouling tape 4 completely detaches from the adhesive surface, and the exposed adhesive layer can be used to stick and fix the catheterization kit body 1 to the edge of the hospital bed.

[0033] Preferably, the fixing block 18 is an elastic snap-fit ​​structure with a guide slope at the front end and a vertical snap-fit ​​surface at the rear end. The fixing hole 6 is a rectangular through hole opened at one end of the urinary catheterization kit body 1. When the placement shell 11 moves downward, the guide slope at the front end of the fixing block 18 contacts the edge of the fixing hole 6, generating elastic deformation so that the fixing block 18 can smoothly enter the fixing hole 6. When the placement shell 11 moves to its maximum stroke, the vertical snap-fit ​​surface at the rear end of the fixing block 18 abuts against the hole wall of the fixing hole 6, preventing the placement shell 11 from retracting upward. The fixing block 18 and the placement shell 11 are integrally injection molded, and the material is polypropylene (PP) or polyoxymethylene (POM). Its elastic modulus ensures that the snap-fit ​​force is controlled within the range of 5N~20N, which not only ensures the snap-fit ​​stability but also makes it easy for medical staff to manually release the snap-fit ​​when needed. When the fixing block 18 is in place, the snap-fit ​​between the fixing block 18 and the fixing hole 6 produces a perceptible "click" sound and vibration, indicating that the placement shell 11 has been fixed in place.

[0034] Working principle: When the catheterization kit body 1 needs to be used, first hold the multiple traction straps 3, then tear off the sealing tapes 2 pasted on the upper and lower ends of the catheterization kit body 1 respectively, and then pull down the pull strip 7. On the one hand, by pulling the pull strip 7, the placement shell 11 and the drainage bag 14 are pulled down. When the placement shell 11 moves, one of the racks 10 moves simultaneously, which in turn drives the meshing gear 9 to rotate, and causes the other rack 10 to move up, and simultaneously drives the placement shell 12 to move up, so as to realize the downward movement of the placement shell 11 and the upward movement of the placement shell 12. When the housing 12 is inside the catheterization kit body 1, the sealing plate 13 is blocked by the inside of the catheterization kit body 1 and cannot be opened by the hinge. When the housing 12 moves up to the upper side of the catheterization kit body 1, the sealing plate 13 is no longer in contact with the catheterization kit body 1. Then the sealing plate 13 rotates clockwise naturally by the hinge and opens the retrieval slot at one end of the housing 12. Medical staff can then retrieve and use the items inside the housing 12 through the retrieval slot. As the placement shell 11 descends, the pulling strap 5 also descends simultaneously, gradually tearing the anti-fouling tape 4 off the surface of the adhesive. After the placement shell 11 descends to its maximum position, the anti-fouling tape 4 is completely detached from the adhesive. At this point, the urinary catheterization kit body 1 can be glued to the hospital bed or other locations using the adhesive, thereby fixing and stabilizing the placement shell 11 and its internal drainage bag 14.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
