Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a quick-installation fixing part for indwelling tube assembly. Background Art

[0002] Indwelling tubes have various applications in the medical field, mainly including indwelling tubes for kidney stone surgery, central venous catheters, and other types of indwelling tubes, such as gastric tubes, etc.; medical gastric indwelling tubes, usually simply referred to as indwelling gastric tubes, are a kind of medical auxiliary tool. The indwelling gastric tube can directly provide food, moisture, and medicine through the tube, ensuring that the patient intakes sufficient calories, proteins, and other various nutrients, meeting their nutritional needs, and facilitating early recovery.

[0003] The nutrient solution tube is sleeved with the gastric tube. However, the existing fixing method generally involves manually adding sealing filler at the connection between the two, then sleeving, and finally winding again outside the connection. This makes the operation very cumbersome in the actual application process, and the sealing effect cannot reach a unified standard. Therefore, a quick-installation fixing part for indwelling tube assembly is proposed. Summary of the Invention

[0004] To solve the problems of the very cumbersome operation and poor sealing effect of the traditional fixing method proposed in the above background art, the present invention provides a quick-installation fixing part for indwelling tube assembly.

[0005] To achieve the above object, the present invention provides the following technical solution: A quick-installation fixing part for indwelling tube assembly, including a gastric tube and a tee connection assembly. One end of the tee connection assembly away from the gastric tube is installed with a nutrient solution tube, and further includes: A connection fixing component, the connection fixing component is located at the connection between the tee connection assembly and the nutrient solution tube, and a third sealing member is arranged inside the connection fixing component; Wherein, the connection fixing component includes a first housing and a second housing. Clamping blocks are slidably connected inside both the first housing and the second housing. Sliding abutting blocks are slidably connected inside both the first housing and the second housing. Elastic pieces are installed on both sides of the clamping blocks.

[0006] Preferably, the first housing and the second housing are fixedly connected through a flexible connecting piece. First sealing members are arranged on the mutually abuting surfaces of the first housing and the second housing. The first housing and the second housing can be closed from an open state to form a closed state, so that the first housing and the second housing are closed to form a tubular fixing fastener for fixing the nutrient solution input interface and the nutrient solution tube.

[0007] Preferably, the apertures at both ends inside are different after the first housing and the second housing are closed, so as to form a stepped inner hole inside after the first housing and the second housing are closed. A plurality of fixing buckles are arranged on the surface of the first housing in contact with the second housing, and a plurality of fixing holes corresponding to the fixing buckles are formed on the second housing.

[0008] Preferably, sliding blocks are arranged on both sides of the clamping block. The pair of clamping blocks can be closed synchronously as the first housing and the second housing are closed, so that the pair of clamping blocks are closed to form a tubular structure. A second sealing member is arranged inside the clamping block.

[0009] Preferably, the top of the sliding abutting block is spirally inclined downward. At the same time, an inclined surface matching the sliding abutting block on the same side is formed at the bottom of the clamping block. The sliding abutting block can slide along the inner walls of the first housing and the second housing, and the clamping block is extruded by the sliding abutting block to move along the first housing or the second housing towards the nutrient solution pipe.

[0010] Preferably, the bottom of the clamping block abuts against the sliding abutting block. At the same time, a fixed abutting block is fixedly connected to the surface of the clamping block on the same side away from the sliding abutting block on the same side. The fixed abutting block coincides with the inclined surface at the top of the sliding abutting block on the different side, and the fixed abutting block abuts against the sliding abutting block.

[0011] Preferably, the elastic sheet is installed on the side of the sliding block away from the fixed abutting block. The pair of clamping blocks are respectively slidably connected to the first housing and the second housing. Positioning grooves are formed on the sides of the clamping blocks away from the fixed abutting block. The positioning grooves form a circular groove after the clamping blocks are closed. The third sealing member is placed inside the positioning grooves.

[0012] Preferably, the tee connection assembly includes a gastric communication interface. An auxiliary function interface is fixedly connected to the side of the gastric communication interface. A nutrient solution input interface is fixedly connected to one end of the gastric communication interface close to the nutrient solution pipe; The nutrient solution input interface is sleeved with the nutrient solution pipe, and one end of the gastric communication interface away from the nutrient solution pipe is fixedly connected to the gastric tube.

[0013] Preferably, the gastric communication interface and the auxiliary function interface are combined to form a Y shape. The nutrient solution input interface is sleeved with the nutrient solution pipe. The nutrient solution input interface is arranged in the middle of the clamping block. At the same time, the third sealing member is sleeved outside the nutrient solution input interface. The third sealing member is located at the socket joint of the nutrient solution input interface and the nutrient solution pipe.

[0014] Preferably, the third seal abuts against the nutrient solution tube. After the first housing and the second housing are closed, the fixed abutting block on the side of the clamping block will squeeze the sliding abutting block on the non - same side, causing the sliding abutting block to squeeze the clamping block to move towards the nutrient solution tube. At the same time, the clamping block pushes the third seal towards the socket between the nutrient solution input interface and the nutrient solution tube. After the first housing and the second housing are completely closed, the fixing buckle is inserted into the second housing, and at the same time, the second seal squeezes and fixes the nutrient solution input interface.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of structures such as the first housing and the second housing, the present invention facilitates quick closing and fixing. The tubular fixing member formed by the flipping and closing of the first housing and the second housing uses the stepped inner hole formed inside it to limit the nutrient solution tube, and clamps and fixes the nutrient solution input interface and the nutrient solution tube after the first housing and the second housing are closed. Through the cooperation of structures such as the clamping block and the third seal, the present invention seals the connection between the nutrient solution input interface and the nutrient solution tube. When the clamping block closes, it will push the third seal to move to the connection between the nutrient solution input interface and the nutrient solution tube. At the same time, the second seal squeezes and abuts against the outer wall of the nutrient solution input interface to form a secondary seal. Finally, the first seals squeeze each other to seal the whole, so as to ensure the seal of the connection between the nutrient solution input interface and the nutrient solution tube. Through the cooperation of structures such as the sliding abutting block and the fixed abutting block, the present invention maintains the fixation and stability of the connection. Through the extrusion of the fixed abutting block, the sliding abutting block squeezes the clamping block to move, causing the clamping block to squeeze the third seal to the connection between the nutrient solution input interface and the nutrient solution tube. Using the closing to push the clamping block to move, the fixation is completed quickly and stably, and its sealing performance is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figures 1 to 7 shown, the present invention provides a quick-install fixing part for assembling an indwelling tube, including a gastric tube 1 and a three-way connection component 2. A nutrient solution tube 3 is installed at one end of the three-way connection component 2 away from the gastric tube 1. It further includes: A fixing component 4 at the connection, which is located at the connection of the three-way connection component 2 and the nutrient solution tube 3, and a third seal 5 is arranged inside the fixing component 4 at the connection; Among them, the fixing component 4 at the connection includes a first housing 401 and a second housing 402. Clamping blocks 404 are slidably connected inside both the first housing 401 and the second housing 402. Sliding abutting blocks 406 are slidably connected inside both the first housing 401 and the second housing 402. Elastic pieces 408 are installed on both sides of the clamping blocks 404.

[0020] Adopting the above solution: By flipping and closing the first housing 401 and the second housing 402, the fixed abutting block 407 squeezes the sliding abutting block 406 at the bottom of the other clamping block 404, so that the sliding abutting block 406 squeezes the clamping block 404 to move towards the nutrient solution tube 3, causing the fixed abutting block 407 to move synchronously until it enters the bottom of the other clamping block 404. At the same time, when the clamping blocks 404 are closed, they will push the third seal 5 towards the socket between the nutrient solution input interface 203 and the nutrient solution tube 3, causing the nutrient solution input interface 203 to move synchronously under the drive of the second seal 405 and the third seal 5 until it is closed. At this time, the nutrient solution input interface 203 will be inserted into the nutrient solution tube 3. At the same time, the third seal 5 is squeezed at the connection between the nutrient solution input interface 203 and the nutrient solution tube 3, and the second seal 405 squeezes and fixes the nutrient solution input interface 203, thus completing the fixation and ensuring the sealing performance.

[0021] As Figures 2 to 7As shown in the figure, the first housing 401 and the second housing 402 are fixedly connected by a flexible connecting member. A first seal 403 is provided on each of the opposing surfaces of the first housing 401 and the second housing 402. The first housing 401 and the second housing 402 can be closed from an open state to a closed state, so that the first housing 401 and the second housing 402 are closed to form a tubular fixing fastener for fixing the nutrient solution input interface 203 and the nutrient solution tube 3. The apertures at both ends inside the first housing 401 and the second housing 402 are different after closing, so as to form a stepped inner hole inside the first housing 401 and the second housing 402 after closing. A plurality of fixing buckles 409 are provided on the surface of the first housing 401 that abuts against the second housing 402, and a plurality of fixing holes corresponding to the fixing buckles 409 are provided on the second housing 402.

[0022] Adopting the above solution: By providing the first housing 401 and the second housing 402, the tubular fixing member formed by the closing of the first housing 401 and the second housing 402 can facilitate the fixing of the connection between the nutrient solution input interface 203 and the nutrient solution tube 3. At the same time, the stepped inner hole inside it can facilitate the limiting of the nutrient solution tube 3. After the first housing 401 and the second housing 402 are closed, the nutrient solution tube 3 is clamped and fixed. The first seal 403 provided on the first housing 401 and the second housing 402 is used to seal the gap after the first housing 401 and the second housing 402 are closed.

[0023] As Figures 3 to 5 shown in the figure, sliding blocks are provided on both sides of the clamping block 404. A pair of clamping blocks 404 can be synchronously closed as the first housing 401 and the second housing 402 are closed, so that a pair of clamping blocks 404 are closed to form a tubular structure. A second seal 405 is provided inside the clamping block 404.

[0024] Adopting the above solution: By providing the clamping block 404, the clamping block 404 can slide inside the first housing 401 and the second housing 402 along the inner walls of the first housing 401 and the second housing 402 through the sliding blocks. At the same time, a tubular member for clamping can be formed after a pair of clamping blocks 404 are closed. The second seal 405 provided inside the clamping block 404 enables the clamping block 404 to squeeze the nutrient solution input interface 203 after closing, so that the nutrient solution input interface 203 is fixed inside the clamping block 404. At the same time, the second seal 405 can seal the connection between the nutrient solution input interface 203 and the clamping block 404.

[0025] As Figures 4 to 7As shown, the top of the sliding abutment block 406 slopes downward in a spiral shape. At the same time, an inclined surface matching the sliding abutment block 406 on the same side is provided at the bottom of the clamping block 404. The sliding abutment block 406 can slide along the inner walls of the first housing 401 and the second housing 402. The sliding abutment block 406 squeezes the clamping block 404 to move along the first housing 401 or the second housing 402 towards the nutrient solution pipe 3. The bottom of the clamping block 404 abuts against the sliding abutment block 406. At the same time, on the side away from the sliding abutment block 406 on the same side of the clamping block 404, a fixed abutment block 407 is fixedly connected. The fixed abutment block 407 fits with the inclined surface at the top of the sliding abutment block 406 on the different side. At the same time, the fixed abutment block 407 abuts against the sliding abutment block 406. The elastic piece 408 is installed on the side of the sliding block away from the fixed abutment block 407. One kind of clamping block 404 is respectively slidably connected to the first housing 401 and the second housing 402. Positioning grooves 410 are provided on the sides of the clamping block 404 away from the fixed abutment block 407. The positioning grooves 410 form a circular groove after the clamping block 404 is closed. The third seal 5 is placed inside the positioning grooves 410.

[0026] Adopting the above scheme: The design of the sliding abutment block 406 is used to push the clamping block 404 to move. The sliding abutment block 406 is set in a spiral shape. At the same time, an inclined surface matching the sliding abutment block 406 is provided at the bottom of the second seal 405. When in the open state, the elastic pieces 408 installed on both sides of the clamping block 404 can push the clamping block 404 to move, so that the clamping block 404 can push the sliding abutment block 406 to slide along the inner walls of the first housing 401 and the second housing 402, thereby squeezing the sliding abutment block 406, causing a part of the sliding abutment block 406 to protrude from the first housing 401. The protruding part corresponds to the fixed abutment block 407. When the first housing 401 and the second housing 402 are closed, it can be squeezed and reset by the fixed abutment block 407, so that the sliding abutment block 406 will push the clamping block 404 towards the nutrient solution pipe 3 to move; While the clamping block 404 is gradually closing and moving towards the nutrient solution pipe 3, it will gradually squeeze the second seal 405 to be in close contact with the nutrient solution input interface 203, so that the nutrient solution input interface 203 can be driven by the second seal 405 and the clamping block 404 to move a certain distance towards the nutrient solution pipe 3, thereby tightening the connection between the nutrient solution input interface 203 and the nutrient solution pipe 3. At the same time, the design of the positioning groove 410 can push the third seal 5 to move and squeeze the third seal 5 at the connection between the nutrient solution input interface 203 and the nutrient solution pipe 3, so that the third seal 5 seals the connection, to ensure the stability and tightness after the connection between the nutrient solution input interface 203 and the nutrient solution pipe 3.

[0027] Such as Figure 1 and Figure 2As shown in the figure, the tee connection assembly 2 includes a gastric connection interface 201. A secondary function interface 202 is fixedly connected to the side of the gastric connection interface 201. One end of the gastric connection interface 201 close to the nutrient solution tube 3 is fixedly connected to a nutrient solution input interface 203; The nutrient solution input interface 203 is sleeved with the nutrient solution tube 3. One end of the gastric connection interface 201 far from the nutrient solution tube 3 is fixedly connected to the gastric tube 1. The gastric connection interface 201 and the secondary function interface 202 are combined to form a Y shape. The nutrient solution input interface 203 is sleeved with the nutrient solution tube 3. The nutrient solution input interface 203 is arranged in the middle of the clamping block 404. At the same time, the third seal 5 is sleeved outside the nutrient solution input interface 203. The third seal 5 is located at the socket of the nutrient solution input interface 203 and the nutrient solution tube 3.

[0028] Adopting the above solution: By setting the tee connection assembly 2, the gastric connection interface 201 is fixedly connected to the gastric tube 1, where the gastric tube 1 leads to the stomach. The secondary function interface 202 arranged on the side of the gastric connection interface 201 is used for injecting drugs or for temporary drainage. The nutrient solution tube 3 connected to the nutrient solution input interface 203 is used for injecting nutrient solution daily.

[0029] As Figures 2 to 7 shown, the third seal 5 abuts against the nutrient solution tube 3. When the first housing 401 and the second housing 402 are closed, at this time, the fixed abutment 407 on the side of the clamping block 404 will squeeze the sliding abutment 406 on the non - same side, causing the sliding abutment 406 to squeeze the clamping block 404 to move towards the nutrient solution tube 3. At the same time, the clamping block 404 pushes the third seal 5 towards the socket of the nutrient solution input interface 203 and the nutrient solution tube 3. After the first housing 401 and the second housing 402 are completely closed, the fixed buckle 409 is inserted into the second housing 402, and at the same time, the second seal 405 squeezes and fixes the nutrient solution input interface 203.

[0030] Adopting the above solution: When the first housing 401 and the second housing 402 are closed, the fixed abutment 407 on the side of the clamping block 404 squeezes the sliding abutment 406 on the other side, causing the sliding abutment 406 to move along the inner walls of the first housing 401 and the second housing 402, squeezing the clamping block 404 towards the nutrient solution tube 3. When the clamping block 404 closes, it pushes the third seal 5 towards the socket of the nutrient solution input interface 203 and the nutrient solution tube 3 until it is closed, and the second seal 405 squeezes and fixes the nutrient solution input interface 203.

[0031] Working principle and usage process of the present invention: During assembly, place the nutrient solution tube 3 at the narrow opening of the second housing 402, then put the third seal 5 on the nutrient solution input interface 203, and place the nutrient solution input interface 203 on the clamping block 404. At the same time, the third seal 5 is located between the clamping block 404 and the nutrient solution tube 3. Then close the first housing 401 and the second housing 402. By flipping the first housing 401 towards the second housing 402, the fixed abutting blocks 407 on the side of the clamping block 404 squeeze the sliding abutting blocks 406 at the bottom of the other clamping block 404, causing the sliding abutting blocks 406 to move along the inner walls of the first housing 401 and the second housing 402, squeezing and moving the clamping block 404 towards the nutrient solution tube 3, and causing the fixed abutting blocks 407 to move synchronously until they enter the bottom of the other clamping block 404. At the same time, when the clamping blocks 404 close, they will push the third seal 5 towards the socket between the nutrient solution input interface 203 and the nutrient solution tube 3, causing the nutrient solution input interface 203 to move synchronously under the drive of the second seal 405 and the third seal 5 until it is closed. At this time, the nutrient solution input interface 203 will insert into the interior of the nutrient solution tube 3. At the same time, the third seal 5 is squeezed at the connection between the nutrient solution input interface 203 and the nutrient solution tube 3, and the second seal 405 squeezes and fixes the nutrient solution input interface 203, thus completing the fixation and ensuring the sealing performance.

[0032] It should be specifically noted that in some embodiments, according to the actual situation of the patient, medical staff will adaptively adjust the insertion length of the nutrient solution input interface. At this time, a set of instrument kits including multiple fixing components with different lengths can be set clinically. Each fixing component is packaged separately for sterilization. When in need of use, medical staff select a fixing component with a suitable length according to the insertion length of the nutrient solution input structure.

[0033] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
