Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary device technology, specifically relating to a chest drainage tube reinforcement device. Background Technology

[0002] Closed chest drainage involves inserting one end of a drainage tube into the pleural cavity, while the other end is connected to a water-seal bottle positioned lower down. This allows for the drainage of gas or collection of fluid from the pleural cavity, enabling the lung tissue to reopen and restore function. It is widely used in thoracic surgery and the treatment of thoracic diseases. During treatment, to prevent displacement of the drainage tube at the wound site due to patient movement, traditional fixation methods primarily use sutures or tape. However, these methods suffer from issues such as insecure fixation and a tendency to loosen. Utility Model Content

[0003] In view of the technical problems existing in the prior art, this utility model provides a chest drainage tube reinforcement device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A chest drainage tube reinforcement device includes a base patch, a base band adhered to the upper end of the base patch, a housing detachably connected to the upper end of the base band, a base block connected to the housing and having a mounting cavity, a tube locking device installed in the mounting cavity, and a locking knob detachably connected to the base block. Both the base patch and the base band have through holes for the drainage tube to pass through and communicating with the mounting cavity. The tube locking device has a through cavity communicating with the through hole for the drainage tube to pass through. The tube locking device includes a plurality of elastic locking elements distributed around the through cavity. The locking knob has a knob cavity communicating with the through cavity and allowing the drainage tube to pass through. Rotating the locking knob in a direction deeper into the housing compresses the elastic locking elements, causing the plurality of elastic locking elements surrounding the drainage tube to lock the drainage tube. Rotating the locking knob in a direction out of the housing separates the locking knob from the elastic locking elements, releasing the locking of the drainage tube.

[0006] Furthermore, the base block has an annular groove on its outer periphery that engages with the outer shell, and the base block also has a screw-in cavity communicating with the mounting cavity, and the locking knob is screwed into the screw-in cavity.

[0007] Furthermore, the sidewall of the mounting cavity is fixed with a plurality of protrusions, which are arranged in a ring around the central axis of the mounting cavity; the corresponding position of the locking device is provided with a slot corresponding to the position of the protrusion, and the locking device is installed in the mounting cavity by inserting the protrusion into the slot.

[0008] Furthermore, the locking device includes an annular base with several slots on its outer periphery and an annular platform coaxially fixed to the upper end of the base. The inner cavity of the base and the inner cavity of the platform communicate to form a cylindrical through cavity with the same diameter. Several elastic locking elements are evenly distributed along the circumference of the top surface of the platform. Each elastic locking element includes an elastic arm with one end fixed to the platform and the other end extending obliquely away from the central axis of the through cavity, and a locking head fixed to the upper end of the elastic arm. The outer surface of the locking head forms a first conical surface, and the larger diameter end of the first conical surface faces the locking knob. The locking knob has a second conical surface formed on the inner wall of the knob cavity corresponding to the position of the elastic locking member. The cone angle of the second conical surface matches the cone angle of the first conical surface. When the locking knob is screwed into the screw cavity in the first rotation direction, the second conical surface and the first conical surface form a sliding fit, forcing the locking heads of each elastic locking member to move synchronously towards the central axis of the through cavity, thereby locking the drainage tube. When the locking knob is screwed out of the screw cavity in the opposite second rotation direction, the elastic locking member resets under its own elastic restoring force, thereby releasing the locking of the drainage tube.

[0009] Furthermore, the bottom surface of the base block has a through-hole for the drainage tube to pass through. One end of the through-hole is connected to the mounting cavity and the other end is connected to the through hole. The inner diameter of the through-hole is smaller than the inner diameter of the mounting cavity.

[0010] Furthermore, the outer shell includes a first half-shell and a second half-shell arranged symmetrically. The connecting end face of the first half-shell is provided with a plurality of locking pins, and the corresponding position of the second half-shell is provided with a plurality of locking grooves that can engage with the locking pins. After the locking pins and the locking grooves are engaged, the first half-shell and the second half-shell can be assembled to form an inner cavity for mounting the base block.

[0011] Furthermore, a ring-shaped component is embedded on the top surface of the baseband, and the ring-shaped component is provided with a number of spaced slots. A number of locking blocks are provided on the bottom surface of the outer casing that correspond to and engage with the slots one by one.

[0012] Furthermore, each side of the baseband is fixedly connected to a side sleeve, and each side sleeve can be detachably connected to a reinforcing strap, and each reinforcing strap is provided with Velcro.

[0013] Furthermore, both the top and bottom surfaces of the base are covered with adhesive layers, and each adhesive layer can be bonded to the release paper.

[0014] In summary, the beneficial effects of this utility model are as follows: 1. The elastic locking component of the tube clamp achieves uniform annular locking of the drainage tube through a double-conical surface linkage mechanism. The depth of the knob can be precisely adjusted to adjust the locking force, avoiding excessive compression that could damage the tube. With the base adhesive and patient fixation, and further reinforcement by the reinforcing strip, the tube's fixation effect is improved, making it less prone to easy dislodgement or removal. 2. The outer shell is quickly assembled via a locking pin and a locking groove, and the base block is fixed to the outer shell via an annular groove, forming a rigid support structure that limits the displacement of the tube clamp under stress. The outer shell is detachable and sterilizable, and the tube clamp can be replaced separately. 3. The silicone locking head of the elastic locking component fixes the tube through static friction, avoiding the cutting damage or deformation of traditional metal clips. Attached Figure Description

Detailed Implementation

[0018] Please see Figure 1 and Figure 2This utility model provides a chest drainage tube reinforcement device, including a base patch 100, a base strip 200 adhered to the upper end of the base patch 100, a housing 300 detachably connected to the upper end of the base strip 200, a base block 400 connected to the housing 300 and having a mounting cavity 410, a tube locking device 500 installed in the mounting cavity 410, and a locking knob 600 detachably connected to the base block 400. Both the base patch 100 and the base strip 200 have through holes for the drainage tube 700 to pass through and communicating with the mounting cavity 410. The tube locking device 500 has a through cavity communicating with the through holes for the drainage tube 700 to pass through. The tube locking device 500 includes several elastic locking elements 530 distributed around the through cavity. The locking knob 600 has a knob passage 610 communicating with the through cavity and allowing the drainage tube 700 to pass through. Rotating the locking knob 600 towards the interior of the housing 300 compresses the elastic locking elements 530, causing the elastic locking elements 530 surrounding the drainage tube 700 to lock it. Rotating the locking knob 600 towards the exit of the housing 300 separates the locking knob 600 from the elastic locking elements 530, releasing the lock on the drainage tube 700. The base patch 100 is preferably made of silicone, and the base tape 200 is preferably made of a high-molecular polymer such as polyvinyl alcohol or polyacrylic acid. During closed chest drainage, the drainage tube 700 extends into the knob passage 610, then into the through cavity, and finally extends from the through hole, ultimately being inserted into the patient's drainage site. The base patch 100 is adhered to the patient's chest cavity. Rotating the locking knob 600 utilizes the elastic locking element 530 to encircle the drainage tube 700, thus securing the drainage tube 700. Based on the base patch 100, this further reinforces the drainage tube 700, reducing the likelihood of accidental dislodgement or pull-out. The knob design allows for easy one-handed operation to fix or loosen the tube, making it simple and convenient.

[0019] The top and bottom surfaces of the base 100 are covered with adhesive layers, each of which can bond with the release paper. Unused base 100 is protected by the release paper. The base 100 has a notch that communicates with the through hole on the base 100. The notch facilitates the smooth entry of the drainage tube 700 into the through hole during base 100 replacement.

[0020] Both sides of the base band 200 are fixedly connected to a side sleeve 220. Each side sleeve 220 is detachably connected to a reinforcing band 800, and each reinforcing band 800 is equipped with Velcro. One end of the reinforcing band 800 extends into the side sleeve 220 and is folded over and secured with Velcro, thereby connecting the reinforcing band 800 to the side sleeve 220. The other end of the reinforcing band 800 is also equipped with Velcro. After the base band 100 is attached to the patient's drainage site, the two reinforcing bands 800 are connected together by the Velcro, further fixing the reinforcing device to the patient, enhancing the fixation strength, and preventing device displacement.

[0021] A ring-shaped component 210 is embedded on the top surface of the baseband 200. The ring-shaped component 210 has several spaced-apart slots. Several locking blocks 330 are provided on the bottom surface of the outer casing 300, which are engaged with the slots one by one. The outer casing 300 is easy to disassemble, and the outer casing 300 and other components can be reused after disinfection, saving costs.

[0022] The outer casing 300 includes a symmetrically arranged first half-shell 310 and a second half-shell 320. The connecting end face of the first half-shell 310 is provided with several locking pins, and the corresponding positions of the second half-shell 320 are provided with several engaging slots 321 that can engage with the locking pins. After the locking pins and engaging slots 321 engage, the first half-shell 310 and the second half-shell 320 can be assembled to form an inner cavity for mounting the base block 400. Both the outer casing 300 and the base block 400 can preferably be made of transparent plastic or similar materials for easy observation of the internal drainage. When the pipe locking device 500 or the base block 400 malfunctions, it is not necessary to replace the entire device; only the outer casing 300 needs to be disassembled to replace the internal components individually.

[0023] The base block 400 has a through-hole 430 on its bottom surface for the drainage tube 700 to pass through. One end of the through-hole 430 communicates with the mounting cavity 410, and the other end communicates with the through hole. The inner diameter of the through-hole 430 is smaller than the inner diameter of the mounting cavity 410. The through-hole 430 serves as a communication channel between the mounting cavity 410 and the through hole. Its fixed size and position guide the drainage tube 700 to accurately pass through the base block 400, preventing the tube from bending or folding inside the base block 400. The clear structural design facilitates medical personnel in quickly passing the drainage tube 700 sequentially through the knob cavity 610, the through cavity, the through-hole 430, and the through hole, reducing alignment difficulties during assembly and improving operational efficiency.

[0024] The base block 400 has an annular groove on its outer periphery that engages with the outer shell 300. The cross-section of the first half shell 310 and the second half shell 320 is similar to an inverted L-shaped structure. The end away from the annular part 210 can be engaged in the annular groove to restrict the position of the base block 400.

[0025] The base block 400 also has a screw-in cavity 420 adjacent to and communicating with the mounting cavity 410. The locking knob 600 is screwed into the screw-in cavity 420. This design allows medical personnel to precisely control the compression or release of the locking device 500 by rotating the knob. In addition, for ease of operation, the outer circumference of the locking knob 600 is provided with anti-slip texture 620 to improve operational stability.

[0026] The side wall of the mounting cavity 410 is fixed with several protrusions, which are arranged in a ring around the central axis of the mounting cavity 410. The corresponding position of the locking device 500 has a slot 511 corresponding to the position of the protrusion. The locking device 500 is installed in the mounting cavity 410 by inserting the protrusion into the slot 511. The protrusions on the side wall of the mounting cavity 410 and the slots 511 of the locking device 500 correspond and match. Installation is completed simply by aligning and inserting the locking device 500, and the protrusions embedding into the slots 511, without complex adjustments. The positioning function of the protrusions and slots 511 ensures that the force direction on the locking device 500 remains stable during the rotation of the locking knob 600, preventing displacement of the locking device 500 due to knob operation and ensuring the safety and reliability of the operation process.

[0027] The locking device 500 includes an annular base 510 with several slots 511 on its outer periphery and an annular platform 520 coaxially fixed to the upper end of the base 510. The inner cavity of the base 510 and the inner cavity of the platform 520 communicate to form a cylindrical through cavity with the same diameter. Several elastic locking elements 530 are evenly distributed along the circumference of the top surface of the platform 520. Each elastic locking element 530 includes an elastic arm 531 with one end fixed to the platform 520 and the other end extending inclined away from the central axis of the through cavity, and a locking head 532 fixed to the upper end of the elastic arm 531. The outer surface of the locking head 532 forms a first conical surface 5320, and the large-diameter end of the first conical surface 5320 is positioned facing the locking knob 600. The inner wall of the knob cavity 610 of the locking knob 600 has a second conical surface 611 formed at the position corresponding to the elastic locking member 530. The cone angle of the second conical surface 611 matches the cone angle of the first conical surface 5320. When the locking knob 600 is screwed into the screw cavity 420 in the first rotation direction, the second conical surface 611 and the first conical surface 5320 form a sliding fit, forcing the locking heads 532 of each elastic locking member 530 to move synchronously towards the central axis of the through cavity, thereby locking the drainage tube 700. When the locking knob 600 is screwed out of the screw cavity 420 in the opposite second rotation direction, the elastic locking member 530 resets under its own elastic restoring force, thereby releasing the locking of the drainage tube 700. The locking head 532 is preferably made of silicone, which generates static friction rather than rigid engagement during locking. This avoids the cutting damage to the pipe caused by traditional metal clips, or prevents the lumen from becoming blocked due to excessive compression when locking the thin-walled drainage tube 700. When the pipe diameter changes, there is no need to replace the locking device 500; it can be adjusted adaptively simply by rotating the knob, making it highly versatile.

[0028] This reinforcement device comprises: 1. The elastic locking element 530 of the tube locking device 500, through a double-conical surface linkage mechanism, achieves uniform annular locking of the drainage tube 700. The depth of the knob can be precisely adjusted to adjust the locking force, avoiding excessive compression that could damage the tube. With the base adhesive 100 securing it to the patient and the reinforcement tape 800 further reinforcing it, the fixation effect of the drainage tube 700 is improved, making it less prone to easy dislodgement or removal. 2. The outer shell 300 is quickly assembled with the locking pin and locking groove 321. The base block 400 is fixed to the outer shell 300 through an annular locking groove, forming a rigid support structure that restricts the displacement of the tube locking device 500 under stress. The outer shell 300 is detachable and sterilizable, and the tube locking device 500 can be replaced separately. 3. The silicone locking head 532 of the elastic locking element 530 fixes the tube through static friction, avoiding the cutting damage or deformation of traditional metal clips.

Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
