[0001] The present invention relates to the technical field of medical devices, in particular to a quick-clamping-based chest tube fast-fixing device. Background Art

[0002] Thoracentesis, also known as closed chest drainage, is a common thoracic surgery procedure that drains gas and fluid from the chest cavity. After the operation is completed, a chest tube is left in the patient's body for subsequent drainage.

[0003] For the connection between the chest tube and the patient's body, the existing technology mainly adopts medical tape connection or medical tape and buckle matching to connect. Among them, the connection method of medical tape and buckle matching is more practical because the buckle can be replaced.

[0004] However, during drainage, the diameter of the chest tube used varies depending on the patient's condition, and the corresponding buckle will also change. During this process, firstly, using an inappropriate buckle will cause the chest tube to loosen, affecting the stability of the connection between the chest tube and the patient's body. Secondly, the buckle needs to be developed in different models according to the size of the chest tube, resulting in increased subsequent use costs. Summary of the Invention

DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0043] See also Figures 1 to 10 In an embodiment of the present invention, a quick-fixing device for a chest tube based on quick clamping includes: a medical single-sided patch 1, a first arc-shaped member 7, a pulling plate 12 and a pushing structure.

[0044] The medical single-sided patch 1 is detachably provided with a connecting plate 4. Specifically, a soft portion 101 and a hard portion 102 are formed on the medical single-sided patch 1. The hard portion 102 is connected to the connecting plate 4 via a locking assembly. An adhesive is provided on the side of the soft portion 101 close to the patient's body. The adhesive enables the medical single-sided patch 1 to be stably attached to the patient's skin. Micropores are provided on the soft portion 101. The micropores enable the area of ​​the patient covered by the soft portion 101 to breathe, thereby reducing the patient's discomfort in this area.

[0045] The locking assembly includes two groups of connecting tubes 2 fixedly mounted on the hard part 102 and an insertion rod 5 fixedly connected to the connecting plate 4. The connecting tube 2 is provided with a first straight groove 201 along its length direction. The insertion rod 5 can be inserted into the connecting tube 2. During use, by inserting the insertion rod 5 into the connecting tube 2, a rigid connection between the connecting plate 4 and the hard part 102 can be achieved, so that the connecting plate 4 can have higher stability when in use.

[0046] A twist lock structure is provided between one group of the insertion rods 5 and the connecting tube 2, and the twist lock structure is used to fix the insertion rods 5 and the connecting tube 2. The interior of the group of insertion rods 5 is a hollow structure;

[0047] The rotary lock structure includes a rotating rod 6 that is rotatably sleeved with the insertion rod 5. A protruding shaft 601 is provided on the outer circumference of one end of the rotating rod 6, and the rotating rod 6 is abutted and adapted with the first cylindrical spring 3 provided inside the connecting tube 2.

[0048] The rotary lock structure also includes a locking groove arranged on the connecting pipe 2 and connected to the first straight groove 201, and the locking groove includes an arc groove 202 connected to the end of the first straight groove 201 and a second straight groove 203 connected to the end of the arc groove 202 away from the first straight groove 201, and the second straight groove 203 is parallel to the first straight groove 201.

[0049] In the initial state, the first cylindrical spring 3 is in a natural state. The direction of the convex shaft 601 is adjusted to be vertically upward, and then the insertion rod 5 is inserted into the connecting tube 2. During this process, the convex shaft 601 can move along the first straight groove 201. When the end of the rotating rod 6 abuts against the first cylindrical spring 3, the connecting plate 4 is continuously pushed to move, so that the rotating rod 6 can squeeze the first cylindrical spring 3 and compress the first cylindrical spring 3. When the convex shaft 601 moves to the end of the first straight groove 201, the rotating rod 6 is rotated to enable the convex shaft 601 to move along the arc groove 202, and when the convex shaft 601 moves to the arc groove 20 2, the connecting plate 4 is released. At this time, the first cylindrical spring 3 pushes the rotating rod 6 to move by releasing the elastic potential energy, so that the convex shaft 601 can enter the second straight groove 203, and when the convex shaft 601 moves to the end of the second straight groove 203, it is locked. In this locked state, since the rotating rod 6 and the connecting tube 2 are in an axially locked state, the rotating rod 6 cannot rotate relative to the connecting tube 2. At the same time, the convex shaft 601 abuts against the end of the second straight groove 203, so that the inserted rod 5 cannot be displaced relative to the connecting tube 2, thereby ensuring the connection stability between the hard portion 102 and the connecting plate 4.

[0050] Furthermore, when the connecting plate 4 needs to be disassembled, the convex shaft 601 is moved along the second straight groove 203 toward the arc groove 202 by pushing the connecting plate 4, and then the rotating rod 6 is rotated in the opposite direction, so that the convex shaft 601 can be reset to the first straight groove 201, thereby separating the connecting plate 4 from the hard part 102 by pulling it out, thereby achieving the effect of portable disassembly, so that the connecting plate 4 can be used sustainably and the cost of use can be reduced.

[0051] Based on the above arrangement, firstly, a detachable connection is realized between the connecting plate 4 and the hard part 102, and the effect of portable disassembly between the connecting plate 4 and the hard part 102 is achieved, so that the connecting plate 4 can be sustainably utilized, and the cost of use is reduced to a certain extent. Secondly, with the cooperation of the convex shaft 601 and the second straight groove 203, the locking between the connecting tube 2 and the inserted rod 5 can be achieved, thereby ensuring the stability when the connecting plate 4 and the hard part 102 are connected.

[0052] See also Figures 5 to 7 The first arc-shaped member 7 is provided with two groups and is slidably mounted on the connecting plate 4. Two groups of second arc-shaped members 8 are symmetrically mounted on the first arc-shaped member 7. The end of the second arc-shaped member 8 away from the first arc-shaped member 7 is connected by an elastic rubber member 9.

[0053] The above-mentioned elastic rubber member 9 has a certain elasticity and toughness, which allows the elastic rubber member 9 to bend and deform and also provide a supporting effect for the two sets of second arc-shaped members 8. Furthermore, the second arc-shaped members 8 are preferably made of a lighter material, such as polypropylene and low-density polyethylene, to prevent the gravity of the upper second arc-shaped member 8 from causing the elastic rubber member 9 to bend in the initial state.

[0054] During the installation of the chest tube, the two groups of first curved members 7 can move toward each other under the drive of the pushing structure. During this process, the elastic rubber member 9 can abut against the chest tube first, and at the same time, the elastic rubber member 9 will bend toward the first curved member 7. At this time, the two groups of second curved members 8 can be deflected toward the chest tube relative to the first curved member 7. When the end of the second curved member 8 away from the first curved member 7 abuts against the chest tube, the elastic rubber member 9 can be tightened and tightly attached to the outer circumferential surface of the chest tube, thereby achieving clamping and fixation of the chest tube.

[0055] Furthermore, when clamping and fixing chest tubes of different diameters, when the second curved member 8 abuts against the outer wall of the chest tube, the deflection amount of the second curved member 8 relative to the first curved member 7 is inconsistent. At that time, as long as the end of the second curved member 8 away from the first curved member 7 abuts against the outer wall of the chest tube, the elastic rubber member 9 can be tightly fitted to the outer side of the circumference of the chest tube, thereby clamping and fixing the chest tube, and relying on the friction between the elastic rubber member 9 and the outer surface of the chest tube, the stability of the chest tube in the clamped state can be guaranteed.

[0056] Based on the above arrangement, firstly, during the clamping process, the end of the second arc-shaped member 8 away from the first arc-shaped member 7 can be deflected to abut against the outer wall of the chest tube, so that the elastic rubber member 9 can fit tightly against the circumferential outer wall of the chest tube, thereby achieving clamping of the chest tube and ensuring clamping stability. Secondly, for chest tubes of different diameters, the second arc-shaped member 8 can deflect to make the elastic rubber member 9 fit tightly against the outer wall of the chest tube, so that the device can be suitable for chest tubes of different diameters, thereby improving the applicability of the device.

[0057] See also Figure 4 、 Figures 8 and 9 The pulling plate 12 is slidably mounted on the connecting plate 4. The pulling plate 12 is provided with an energy storage portion 13. The energy storage portion 13 cooperates with the elastic component provided on the connecting plate 4 to enable the elastic component to have two states: energy storage and energy release. The pulling plate 12 is provided with a guide groove 1201. The guide wheel 15 rotatably mounted on the connecting plate 4 can roll in the guide groove 1201.

[0058] The elastic component includes a transverse plate 16 fixedly connected to the connecting plate 4, and two groups of hysteresis grooves 1601 are symmetrically provided on the transverse plate 16. A group of sliders 19 are slidably installed in each of the two groups of hysteresis grooves 1601, and an abutment wheel 1901 that is rotatably installed on the slider 19 and rolls with the energy storage part 13;

[0059] The elastic assembly further includes a transverse shaft 17 fixedly mounted in the hysteresis groove 1601 and slidably connected to the slider 19. A second cylindrical spring 18 is sleeved on the transverse shaft 17. One end of the second cylindrical spring 18 is connected to the inner wall of the hysteresis groove 1601, and the other end is connected to the slider 19.

[0060] The energy storage portion 13 includes a first inclined surface 1301 and a second inclined surface 1302 symmetrically disposed on the side of the pulling plate 12 . A protrusion extending toward the end of the transverse plate 16 is formed between the first inclined surface 1301 and the second inclined surface 1302 .

[0061] In the initial state, the second cylindrical spring 18 is in a compressed state, and the abutment wheel 1901 is at the end of the second inclined surface 1302 away from the protrusion. At this time, the abutment wheel 1901 is in a stable state, thereby stabilizing the position of the pulling plate 12. At this time, under the connection of the pushing structure, it can ensure that the maximum distance between the two groups of first arc-shaped parts 7 can be maintained, which makes it more convenient to place the chest tube between the two groups of first arc-shaped parts 7.

[0062] When the chest tube is placed between the two groups of first curved members 7, the pulling plate 12 is pushed to move, so that the abutment wheel 1901 can move along the second inclined surface 1302 toward the protrusion. During this process, the second cylindrical spring 18 is further compressed to store elastic potential energy (energy storage state). After the abutment wheel 1901 moves over the protrusion, the second cylindrical spring 18 can push the abutment wheel 1901 to move along the first inclined surface 1301 by releasing the elastic potential energy. At this time, the pulling plate 12 will actively move and use the pulling structure to drive the two groups of first curved members 7 to move closer to each other to achieve clamping of the chest tube. For chest tubes of different diameters, since the abutment wheel 1901 always has a tendency to squeeze the pulling plate 12 during the process of releasing the elastic potential energy of the second cylindrical spring 18, the two groups of first curved members 7 can stop moving after completing the clamping of the chest tube, that is, the above arrangement can ensure that chest tubes of different diameters can be clamped.

[0063] Based on the above arrangement, firstly, the stability of the two groups of first curved members 7 in the initial state can be ensured, making it more convenient to place a chest tube. Secondly, the elastic force provided by the second cylindrical spring 18 drives the two groups of first curved members 7 to move, so that the two groups of first curved members 7 can adaptively stop moving according to the diameter of the clamped chest tube, thereby making the device suitable for chest tubes of different diameters.

[0064] Please refer again Figure 4 、 Figures 8 and 9 The pushing structure connects the pulling plate 12 and the first arc-shaped member 7, and the pushing structure can drive the two groups of first arc-shaped members 7 to move closer to each other when the elastic component is in the energy release state;

[0065] The pushing structure includes two sets of guide grooves 14 symmetrically arranged on the pulling plate 12 and a sliding member 10 slidably mounted on the connecting plate 4 and fixedly connected to the first arc-shaped member 7. The sliding member 10 is rotatably mounted with an engaging wheel 11, and the engaging wheel 11 can roll in the guide groove 14.

[0066] The guide groove 14 includes a retaining groove 1401 and an inclined groove 1402 provided on the pulling plate 12 , wherein the retaining groove 1401 is in communication with the inclined groove 1402 ;

[0067] When the engaging wheel 11 moves along the inclined groove 1402 , the two groups of sliding members 10 can drive the two groups of first arc-shaped members 7 to move closer to or away from each other.

[0068] When external force acts on the pulling plate 12 to make it move, the abutment wheel 1901 moves along the second inclined surface 1302 toward the protrusion, and the engaging wheel 11 can move in the retaining groove 1401. During this process, the distance between the two groups of first arc-shaped members 7 will remain unchanged, so that when the elastic component is in the energy storage state, it is only necessary to overcome the elastic force of the second cylindrical spring 18 without any additional load, so that when the elastic component is in the energy storage state, the force acting on the pulling plate 12 can be smaller, making operation more convenient.

[0069] When the abutment wheel 1901 moves over the protrusion and along the first inclined surface 1301, the engaging wheel 11 will move in the inclined groove 1402. At this time, the two groups of sliding members 10 will drive the two groups of first arc-shaped members 7 to move closer to each other to clamp the chest tube, thereby realizing the effective transmission of the elastic force released by the second cylindrical spring 18.

[0070] See also Figure 10 , the connecting plate 4 is also provided with multiple sets of pipeline constraint structures, and the pipeline constraint structures include a fixing seat 20 fixedly installed on the connecting plate 4 and a covering member 21 rotatably installed on the fixing seat 20, the fixing seat 20 is provided with a protrusion 2001, and the covering member 21 is provided with a groove 2101, and the protrusion 2001 is adapted to the groove 2101.

[0071] The cover 21 is deformable. When in use, the pipeline connected to the chest tube is placed in the fixing seat 20, and then the cover 21 is rotated so that its end acts on the protrusion 2001. The cover 21 can be deformed until the groove 2101 and the protrusion 2001 are engaged, thereby locking the cover 21. Conversely, pulling the cover 21 to rotate in the opposite direction can open the cover 21, and the pipeline connected to the chest tube can be taken out.

[0072] Based on the above arrangement, the pipeline connected to the chest tube can be restrained during use to prevent it from shaking during use, and the cooperation between the cover 21 and the fixing seat 20 has the effect of inertia protection, preventing the pipeline close to the chest tube from being subjected to force and disconnected from the chest tube.
