Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bidirectional tube clamp and a closed chest drainage device. Background Technology

[0002] A closed thoracic drainage device consists of two parts: a drainage tube and a water-seal bottle. One end of the drainage tube is inserted into the thoracic cavity, and the other end is connected to the water-seal bottle, which should always be 60-100 cm below the insertion end of the drainage tube. Its purpose is to drain gas and effusion from the thoracic cavity, promote lung re-expansion, restore negative pressure in the thoracic cavity and lung function. It plays an important role in the clinical treatment of diseases and is widely used in clinical settings such as pneumothorax, hemopneumothorax, empyema, and post-thoracotomy procedures.

[0003] When changing the water-seal solution in the water-seal bottle daily in clinical practice, hemostatic forceps should be used to clamp the drainage tube. Figure 11 As shown, in actual operation, two hemostatic forceps are needed to clamp the drainage tube from two directions to effectively prevent communication between the chest cavity and the outside. However, this operation requires long-term manual maintenance, which is inconvenient for medical staff. At the same time, the conventional chest drainage tube has a large diameter, thick wall, and relatively hard material, which further increases the difficulty and time required for clamping the drainage tube, resulting in poor clinical convenience. Therefore, it is necessary to design a double clamping device for the drainage tube.

[0004] A search revealed existing patents for related double-clamp devices, such as the utility model patent with authorization announcement number CN 217219836U, which discloses a double-clamp clamp for drainage tubes. Although this can achieve double clamping of the drainage tube, it still has the following drawbacks in practical applications:

[0005] When installing this clamp, it must be inserted through a pre-set threading hole from the end of the tubing before it can be slid to the designated clamping position of the drainage tube, making the operation process cumbersome. Furthermore, it is inconvenient to disassemble after installation and cannot be reused, which increases the consumption of medical consumables and raises the cost of clinical use. If it is forcibly disassembled and reused, the clamp may be contaminated due to blood and other pollutants at the end of the drainage tube, posing a potential safety hazard in clinical use.

[0042] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0043] like Figure 1 - Figure 9As shown, this embodiment proposes a bidirectional clamping device for medical tubing 1, suitable for clamping control scenarios, especially for bidirectional controllable clamping of closed chest drainage tube 4. It mainly consists of a clamping body 2 and two sets of clamping components 3. The two sets of clamping components 3 are arranged at intervals and detachably connected to the clamping body 2. The two components work together to achieve bidirectional clamping of tubing 1 and can stably lock the clamped state, meeting the clinical requirements for clamping tubing 1. The following is a detailed description:

[0044] The jacket body 2 includes two mating half-jackets 21. The half-jackets 21 can be solid or hollow. The inner wall of the half-jackets 21 has a through groove 211 along the length direction. The two half-jackets 21 are mated to form the jacket body 2. The two grooves 211 are mated to form a channel for accommodating the pipe 1. In use, when the two half-jackets 21 are mated and spliced ​​together, the two grooves 211 are also mated and enclosed to form a complete channel for accommodating the pipe 1. The pipe 1 can be inserted into the channel to realize the sleeve positioning of the jacket body 2 on the pipe 1.

[0045] Meanwhile, the jacket body 2 has two slots 213 that communicate with the channel along the radial direction; the two slots 213 are spaced apart to provide working space for the clamping action of the subsequent clamping component 3, ensuring that the clamping component 3 can effectively squeeze the tube 1 in the channel through the slots 213. The overall length of the jacket body 2 can be set to 40-100mm, and the diameter of its internal channel can be set to 3-12mm. This specification design can be adapted to medical tubes 1 of different diameters in clinical use, especially various drainage tubes 4 of closed chest drainage, without the need to customize clamps according to the diameter of the tube 1, thus meeting the diverse needs of tube 1 clamping in clinical practice.

[0046] The clamp adopts a mating structure, consisting of two mating half-clamps 21. It can be opened and closed from any position of the pipeline 1 without needing to be inserted from the end of the pipeline 1. The disassembly and assembly operations are flexible, and the disassembly and assembly process will not cause contamination of the bidirectional clamp of the pipeline. It can be reused, effectively reducing the consumption of medical consumables and lowering the cost of clinical use.

[0047] Regarding the two sets of clamping components 3, they are detachably connected to the jacket body 2. The two sets of clamping components 3 are respectively set with two slots 213. The clamping components 3 can be detachably connected to the jacket body 2 and perform clamping operation at the position corresponding to the slots 213. Each set of clamping components 3 includes a pipe clamp 32, a clamping plate 31 and a positioning platform 33. The pipe clamp 32 is a detachable structure. The pipe clamp 32 can be detachably engaged with the jacket body 2 to achieve the overall positioning of the clamping components 3.

[0048] A vertical clamping plate 31 is slidably connected to one side of the pipe clamp 32. The clamping plate 31 is adapted to the slot 213 and can slide up and down along the slot 213. The size of the clamping plate 31 is adapted to the slot 213. It can pass through the slot 213 and be inserted into the channel of the clamp body 2. It can slide up and down along the vertical direction of the slot 213. By sliding down, it squeezes the pipe 1 in the channel, thereby achieving the clamping of the pipe 1.

[0049] The top of the pipe clamp 32 is provided with a flexible positioning platform 33, and the side of the positioning platform 33 near the clamping plate 31 is provided with several positioning teeth. The top of the clamping plate 31 is provided with an engaging part, which can slide down along the positioning teeth and engage with the corresponding positioning teeth at a preset position to lock the clamping state. In use, when the clamping plate 31 is pushed down to perform the clamping operation, the engaging part can slide down along the trajectory of the positioning teeth and engage with the corresponding positioning teeth at the preset clamping position, thereby locking the position of the clamping plate 31 and fixing the clamping state, preventing the clamping plate 31 from loosening and causing clamping failure.

[0050] In some embodiments, the outer wall of the jacket body 2 has two spaced slots 212 along the circumferential direction, and the pipe clamp 32 is positioned and engaged in the corresponding slots 212. By setting the slots 212, on the one hand, it can provide an accurate positioning and installation position for the pressing component 3, ensuring the alignment accuracy between the pressing component 3 and the slot 213, ensuring that the clamping plate 31 can be accurately aligned with the slot 213 and smoothly inserted, avoiding the inability of the clamping plate 31 to effectively squeeze the pipeline 1 due to positional deviation, and ensuring the effectiveness of the clamping operation; on the other hand, through the engagement of the slots 212 and the pipe clamp 32, a detachable connection between the pressing component 3 and the jacket body 2 can be realized. This allows the pressing component 3 to be quickly clamped and fixed, improving the assembly efficiency of the clamp, and also facilitates the subsequent disassembly, replacement and maintenance of the pressing component 3 according to usage requirements. At the same time, the engagement connection method can ensure the connection stability between the pressing component 3 and the jacket body 2 during use, preventing the pressing component 3 from loosening or shifting, and ensuring the stability of the clamping state.

[0051] In some embodiments, the connection between the positioning platform 33 and the clamping plate 31 can be achieved by the following structural design to achieve sliding cooperation between the two: the side wall of the positioning platform 33 is also connected to a threaded rod 35, and a baffle 36 is sleeved and fixed on the threaded rod 35. The baffle 36 and the threaded rod 35 are fixedly connected and will not slide relative to each other; the clamping plate 31 has a vertically arranged sliding groove 311, one end of the threaded rod 35 passes through the sliding groove 311 and is threadedly connected to a nut 34. The nut 34 and the baffle 36 are respectively attached to both sides of the clamping plate 31, forming a limiting platform for the clamping plate 31. When the clamping plate 31 slides up and down, the threaded rod 35 can slide relative to each other along the sliding groove 311. This structure can guide the sliding direction of the clamping plate 31, ensuring that the clamping plate 31 always slides in the vertical direction, and can also effectively prevent the clamping plate 31 from separating from the pipe clamp 32, thereby improving the overall structural stability of the clamping assembly 3.

[0052] It should be noted that the connection method between the threaded rod 35 and the positioning table 33 can be flexibly selected according to the production and processing and actual use requirements. It can be connected by integral molding, bolting or gluing. All three connection methods can ensure the connection strength between the threaded rod 35 and the positioning table 33, avoid loosening or falling off during use, and meet the structural use requirements of clinical operation.

[0053] Each of the two semi-jacketed sleeves 21 has a corresponding fitting groove on its inner wall, in which a magnet 214 is installed. The magnets 214 on the two semi-jacketed sleeves 21 have opposite polarities and can magnetically attract and adhere to each other. When the two semi-jacketed sleeves 21 are aligned, the magnets 214 with opposite polarities will generate a magnetic attraction force, causing the two semi-jacketed sleeves 21 to quickly and tightly adhere. With the help of the magnetic attraction, the two semi-jacketed sleeves 21 can be initially aligned and fixed, allowing the jacket body 2 to form a stable overall structure, providing a foundation for the subsequent installation of the pressure holding component 3. This initial magnetic fixation method, combined with the secondary fixation effect formed by the pipe clamp 32 after it is engaged in the slot 212 of the jacket body 2, can achieve double fixation of the semi-jacketed sleeves 21, further improving the structural stability of the jacket body 2 after closure, effectively preventing the semi-jacketed sleeves 21 from loosening or shifting during use, and ensuring the smooth operation of the pipe 1 clamping.

[0054] In some embodiments, the engaging part is a pressure plate 37, which is fixedly connected to the top of the clamping plate 31. The side edge of the pressure plate 37 can engage with the positioning teeth. The positioning teeth have a triangular structure, with a spacing of 1-2 mm between two adjacent positioning teeth. The surface of the positioning teeth is smoothed to achieve multi-level adjustment of the clamping position, adapting to the clamping requirements of pipelines 1 with different diameters. At the same time, it facilitates the sliding and locking of the pressure plate 37 along the positioning teeth. In use, when the clamping plate 31 is pushed down, the side edge of the pressure plate 37 can slide smoothly along the positioning teeth and accurately engage with the corresponding positioning teeth, thereby locking the position of the clamping plate 31 and fixing the clamping state of the pipeline 1.

[0055] In some embodiments, the surface of the pressure plate 37 is provided with a plurality of anti-slip protrusions, which are hemispherical in shape, thereby increasing the friction when pressing, making it easier for medical staff to operate the pressure plate 37 to clamp and unlock, and improving the ease of operation.

[0056] As can be seen from the above description:

[0057] The pipe clamp 32 of the holding component 3 can be adapted and engaged with the jacket body 2. On the one hand, it can fix the two half jackets 21 in a closed manner, ensuring the structural stability of the jacket body 2 after closure. On the other hand, the pipe clamp 32 is detachable, which is convenient for disassembly and assembly, and is conducive to the overall assembly and maintenance of the clamp. The positioning platform 33 of the holding component 3 is provided with several positioning teeth. The engaging part of the clamping plate 31 can slide down along the positioning teeth and engage at the preset position, improving the reliability of the clamping operation. Moreover, the positioning platform 33 is elastic and can be slightly moved, which can quickly release the clamping lock state during use, making the operation convenient and efficient.

[0058] It should be noted that the top of the positioning platform 33 and the pipe clamp 32 can be connected and fixed by integral molding, bolting, or adhesive bonding, which can be flexibly selected according to production processing and actual use requirements. In some embodiments, bolting is preferred. The top of the pipe clamp 32 has a corresponding through hole 321, and the bottom of the positioning platform 33 has a threaded hole corresponding to the through hole 321. A screw 38 is inserted into the through hole 321. After the screw 38 passes through the through hole 321, it can be screwed into the threaded hole to achieve a firm fixation between the positioning platform 33 and the pipe clamp 32. This connection method is convenient for disassembly and assembly, and also facilitates the subsequent replacement and maintenance of the positioning platform 33.

[0059] In some embodiments, the bottoms of the two half-jackets 21 are connected by a flexible connecting strap 22. The connecting strap 22 forms a linked whole structure for the two half-jackets 21, which can effectively prevent the half-jackets 21 from separating or being lost during the opening and closing operation, and does not restrict the normal alignment and opening of the two half-jackets 21. At the same time, the flexible material connecting strap 22 has good bending properties and can flexibly adapt to the opening and closing angle of the half-jackets 21, making it convenient for medical staff to directly open and close the jacket body 2 from any position of the pipeline 1, greatly improving the flexibility and convenience of operation.

[0060] In some embodiments, the clamping plate 31 has an arc-shaped clamping surface at one end near the channel. The curvature of the arc-shaped clamping surface matches the curvature of the inner wall of the channel. The arc-shaped clamping surface has a flexible buffer layer made of medical rubber. The flexible buffer layer can fit the outer wall of the pipeline 1 when clamping the pipeline 1, so as to avoid excessive clamping pressure and damage to the pipeline 1, while improving the clamping sealing performance.

[0061] In some embodiments, the jacket body 2, pipe clamp 32, clamping plate 31, pressure plate 37 and positioning platform 33 are all made of medical-grade materials. The medical-grade materials are any one of medical ABS plastic, medical PC plastic or medical nylon, which meet the biocompatibility requirements of medical devices, are non-toxic and non-irritating, and are suitable for the use needs of clinical medical scenarios.

[0062] The operating steps of the bidirectional pipe clamp in this embodiment are as follows:

[0063] a. Open the two half-clamps 21, place the pipe 1 to be clamped in the groove 211 of the half-clamps 21, and use the magnetic attraction force of the magnet 214 to make the two half-clamps 21 fit tightly together to form the clamp body 2 that wraps the pipe 1.

[0064] b. Engage the pipe clamps 32 of the two sets of clamping components 3 into the corresponding slots 212 on the outer wall of the jacket body 2 to complete the positioning and installation of the clamping components 3. At the same time, the pipe clamps 32 form a secondary fixation for the two half jackets 21.

[0065] c. When it is necessary to clamp the pipeline 1, push the clamping plate 31 downward so that the clamping plate 31 passes through the slot 213 and squeezes the pipeline 1 until the pressure plate 37 engages with the positioning teeth at the preset position on the positioning table 33, thereby locking the clamping state. The two sets of pressing components 3 cooperate to complete the bidirectional clamping of the pipeline 1.

[0066] d. When it is necessary to release the clamp, slightly move the elastic positioning table 33 to separate the positioning teeth from the pressure plate 37, and pull the clamping plate 31 upward to the initial position to release the clamp on the pipeline 1. If it is necessary to disassemble the clamp, simply remove the pipe clamp 32 and pry open the half clamp 21. The entire operation does not require passing through the end of the pipeline 1, and the disassembly and assembly are flexible.

[0067] Specific application examples of bidirectional pipe clamps:

[0068] The application scenarios of bidirectional tube clamps cover various surgical drainage tubes, infusion tubes, urological tubes, and gastroenterology decompression tubes. They can replace traditional tools, improve the convenience and safety of operation, and are suitable for multiple scenarios such as wards and outpatient and emergency departments.

[0069] Taking closed thoracic drainage as an example, such as Figure 10 As shown, Figure 10 This is a schematic diagram of a closed thoracic drainage device. The device includes a drainage tube 4 and a drainage bottle 5 (also known as a water-seal bottle). The drainage bottle 5 contains a water-seal fluid. One end of the drainage tube 4 is inserted into the pleural cavity, and the other end is connected to the drainage bottle 5, which is submerged in the water-seal fluid. An exhaust pipe 6 is also connected to the drainage bottle 5. The device is equipped with the aforementioned bidirectional clamping device. The drainage tube 4 is the tubing 1. The bidirectional clamping device is detachably fitted onto the drainage tube 4 to achieve bidirectional controllable clamping of the drainage tube 4, meeting the clinical needs for clamping and controlling the drainage tube 4 during closed thoracic drainage procedures.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
