Description

Technical Field

[0001] This utility model relates to the field of clamp valve technology, and in particular to a manually adjustable return pipe clamp. Background Technology

[0002] In the medical field, blood purification therapy is a crucial technology widely used in the treatment of severe kidney diseases such as uremia and acute kidney injury. During this process, the reinfusion clamp, as a key component of the blood purification equipment, plays a vital role in controlling the opening and closing of the blood reinfusion line. However, in practice, the design of the reinfusion clamp often has certain limitations, especially in scenarios where the line needs to be clamped and subsequently removed.

[0003] The reinfusion clamps on existing blood purification devices generally lack consideration for ease of catheter retrieval in their design. When situations arise during treatment, such as emergency shutdown, treatment completion, tubing malfunction, changes in patient position, or coagulation risks, the reinfusion clamp will quickly respond and close the tubing. However, once the tubing is clamped, due to the clamping force and structural design of the clamp, medical staff often find it difficult to easily remove it. Traditional methods usually require brute force to pull it out, which not only increases the difficulty and time required but may also cause unnecessary damage to the tubing, even affecting the patient's treatment outcome and safety.

[0004] To address the aforementioned issues, designing a more user-friendly and easily operable manually adjustable reinfusion clamp is of paramount importance. This new clamp should possess the following characteristics: First, when clamping the tubing, it should reliably maintain the clamped state to ensure no blood leakage; second, when removing the tubing, the clamp should be easily released through a simple operation, allowing the tubing to be easily released from the clamp.

[0005] In summary, the manually adjustable reinfusion clamp design of this application aims to solve the problem that the reinfusion clamp of existing blood purification equipment is difficult to remove easily after clamping the tubing. Utility Model Content

[0006] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a manually adjustable reinfusion clamp that can be released by simple manual operation after the tubing is clamped, so that the tubing can be easily released from the clamp, thereby improving the safety and convenience of the treatment process.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a manually adjustable return pipe clamp, comprising:

[0008] The valve body has a receiving groove at its upper end for accommodating a flexible hose.

[0009] The clamping part is located inside the valve body, with one end of the clamping part penetrating through the valve body and located in the receiving groove;

[0010] An adjustment component is used to drive the clamping part to move along the length of the valve body;

[0011] When the adjusting component is in the first position, it drives the clamping part to remain in the first position, at which time the pipeline is clamped; when the adjusting component is in the second position, it drives the clamping part to remain in the second position, at which time the pipeline is released.

[0012] As a further improvement of this utility model, the adjustment assembly includes a wrench, a transmission connecting plate connected to the clamping part, and a push rod connected to the transmission connecting plate. One end of the wrench abuts against the top of the transmission connecting plate. When the wrench moves, it drives the transmission connecting plate, the clamping part, and the push rod to move along the length of the valve body.

[0013] As a further improvement of this utility model, the valve body has a top opening, and the wrench includes a vertically connected vertical section and a horizontal section. The top of the vertical section passes through the opening and is located above the valve body. The lower outer wall of the vertical section is rotatably connected to the inner wall of the upper opening of the valve body. The free end of the horizontal section abuts against the top of the transmission connecting plate.

[0014] When the vertical section is rotated, the end of the horizontal section away from the vertical section moves downward, causing the transmission connecting plate and push rod to move downward, thereby causing the clamping part to move downward, and the hose located at the top of the clamping part is released; when the vertical section rotates in the opposite direction, the end of the horizontal section away from the vertical section moves upward, causing the transmission connecting plate and push rod to move upward, thereby causing the clamping part to move upward, and the hose located at the top of the clamping part is clamped.

[0015] As a further improvement of this utility model, the free end of the horizontal segment is chamfered.

[0016] As a further improvement of this utility model, the clamping part includes a clamping block and a clamping plate connected to the top of the clamping block, and the clamping plate is arranged parallel to the opening direction of the receiving groove.

[0017] As a further improvement of this utility model, it also includes a drive assembly disposed in the valve body, the drive assembly including a magnet and a piston rod, one end of the piston rod passing through the magnet and connected to a push rod.

[0018] As a further improvement of this utility model, it also includes a limiting component, which includes a limiting block and an elastic element connected to the limiting block. One end of the limiting block passes through the top of the valve body and is located on one side of the inlet of the receiving groove, and the other end is connected to the elastic element. The other end of the elastic element is fixed to the bottom inner wall of the valve body.

[0019] As a further improvement of this utility model, the valve body is also provided with a micro switch assembly for detecting whether there is an installed pipeline. The micro switch assembly includes a clamping block and a micro switch. One end of the clamping block passes through the valve body and extends outward into the receiving groove. The other end of the clamping block contacts the moving contact of the micro switch. The micro switch is fixed to the bottom inner wall of the valve body by a fixing block.

[0020] As a further improvement of this utility model, it also includes a connecting seat, which is fixed on the lower peripheral wall of the valve body.

[0021] Compared with the prior art, this utility model has the following advantages:

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0030] Figures 1 to 5 The diagram shown is a structural schematic of one embodiment of a manually adjustable return pipe clamp of the present invention, the main body of which includes a valve body 100, a clamping part 200 and an adjusting component 300.

[0031] The valve body 100 is used for the installation of the clamping part 200 and the adjusting assembly 300. The upper end of the valve body 100 is provided with a receiving groove 110 for accommodating the hose. The receiving groove 110 is arranged radially along the valve body 100 and is in the shape of an inverted U-shape adapted to the hose.

[0032] The clamping part 200 is used to clamp the hose in the receiving groove 110. It is located inside the valve body 100, with an opening at the top of the valve body 100. One end of the clamping part 220 passes through the opening at the top of the valve body 100 and is located inside the receiving groove 110. Specifically, the clamping part 200 includes a clamping block 210 and a clamping plate 220 connected to the top of the clamping block 210. The clamping plate 220 is arranged parallel to the opening direction of the receiving groove 110. In use, the hose is placed on the clamping plate 220, and the hose is clamped between the upper inner wall of the receiving groove 110 and the clamping plate 220. Preferably, in this embodiment, in order to reduce damage to the hose, the top of the clamping plate 220 is provided with a rounded chamfer.

[0033] The adjusting assembly 300 is used to drive the clamping part 200 to move along the length direction of the valve body 100. When the adjusting assembly 300 is in the first position, it drives the clamping part 200 to maintain the first position, at which time the hose is clamped. When the adjusting assembly 300 is in the second position, it drives the clamping part 200 to maintain the second position, at which time the hose is released. Specifically, the adjusting assembly 300 includes a wrench 310, a transmission connecting plate 320 connected to the clamping part 200, and a push rod 330 connected to the transmission connecting plate 320. One end of the wrench 310 abuts against the top of the transmission connecting plate 320, and is used to drive the transmission connecting plate 320, the clamping part 200, and the push rod 330 to move as a whole along the length direction of the valve body 100. The wrench 310 includes a vertically connected vertical section 3110 and a horizontal section 3120. The top of the vertical section 3110 passes through an opening and is located above the valve body 100. The lower side wall of the vertical section 3110 is rotatably connected to the inner wall of the opening in the valve body 100. The free end of the horizontal section 3120 abuts against the top of the transmission connecting plate 320. When the vertical section 3110 is rotated, the end of the horizontal section 3120 away from the vertical section 3110 moves downward, causing the transmission connecting plate 320 and the push rod 330 to move downward, thereby causing the clamping part 200 connected to the transmission connecting plate 320 to move downward, and the hose at the top of the clamping part 200 is released. When the vertical section 3110 rotates in the opposite direction, the end of the horizontal section 3120 away from the vertical section 3110 moves upward, the transmission connecting plate 320 and the push rod 330 move upward, thereby causing the clamping part 200 to move upward, and the hose at the top of the clamping part 200 is clamped. Preferably, in this embodiment, the free end of the horizontal segment 3120 is chamfered to facilitate the rotational movement of the wrench 310.

[0034] The drive assembly 400 is used to drive the push rod 330 to move along the length of the valve body 100. The drive assembly 400 includes a magnet 410 and a piston rod 420, one end of which passes through the magnet 410 and is connected to the push rod 330. By energizing or de-energizing the magnet 410, the tubing can be clamped or released. During normal use of the equipment, the tubing located at the top of the clamping plate 220 is in the released state, and the liquid in the tubing flows normally. In case of an emergency during treatment, the return tubing clamp will respond quickly and clamp the tubing. When it is necessary to remove the tubing, the medical staff only needs to gently press the wrench 310. At this time, the piston rod 420 moves downward, driving the push rod 330, the transmission connecting plate 320 and the clamping part 200 to move downward as a whole, thereby gradually loosening the clamp on the tubing. This process does not require brute force, which not only greatly reduces the difficulty and time of operation, but also reduces the potential risk of damage to the tubing.

[0035] Preferably, in this embodiment, a connecting seat 700 is also included. The connecting seat 700 is fixed on the lower peripheral wall of the valve body 100 and is used for connection with the host device.

[0036] Combination Figures 1 to 5 This embodiment provides a manually adjustable reinfusion clamp, the specific usage process of which is as follows: When it is necessary to remove the clamped tubing, the medical staff gently presses the wrench 310. The wrench 310, through the piston rod 420, moves the clamp 220 downward, causing the clamping part 200 to loosen its grip on the tubing. When the clamp 220 moves to a certain position, the tubing can be easily released from the clamp and removed, improving the flexibility and ease of operation of the clamp, and providing medical staff with a safer and more efficient treatment tool. Example 2

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in Embodiment 2, based on Embodiment 1, a limiting component 500 is provided to prevent the hose from slipping off the clamping part 200 when it is clamped. The limiting component 500 includes a limiting block 510 and an elastic member 520 connected to the limiting block 510. One end of the limiting block 510 passes through the top of the valve body 100 and is located on one side of the inlet of the receiving groove 110, while the other end is connected to the elastic member 520. The other end of the elastic member 520 is fixed to the bottom inner wall of the valve body 100. When the equipment is in use, the elastic element 520 is in its initial state, and the top of the limiting block 510 abuts against the top inner wall of the receiving groove 110. At this time, the limiting block 510 seals the notch of the receiving groove 110, and the pipeline is restricted within the receiving groove 110 to prevent the pipeline from slipping off the clamping part 200. When it is necessary to remove the pipeline from the receiving groove 110, press down on the top of the limiting block 510. At this time, the elastic element 520 is in a compressed state, and the top of the limiting block 510 is flush with the bottom inner wall of the receiving groove 110. At this time, the pipeline can be removed from the receiving groove 110. Example 3

[0038] like Figure 1 , Figure 3 and Figure 4As shown, in Example 3, based on Example 1, in order to detect whether the return pipe clamp has an installed pipeline, a micro switch assembly 600 is also provided in the valve body 100. The micro switch assembly 600 includes a clamping block 610 and a micro switch 620. One end of the clamping block 610 passes through the valve body 100 and extends outward into the receiving groove 110. The other end of the clamping block 610 is in contact with the moving contact of the micro switch 620. The micro switch 620 is fixed to the bottom inner wall of the valve body 100 by a fixing block 630. When the pipeline is clamped within the receiving groove 110, the clamping block 610 moves towards the moving contact of the micro switch 620, connecting the moving contact of the micro switch 620 with its fixed contact. When there is no pipeline in the receiving groove 110, the clamping block 610 moves away from the moving contact of the micro switch 620, separating the moving contact of the micro switch 620 from its fixed contact. By using the clamping block 310 to connect or disconnect the moving and fixed contacts of the micro switch 320, the presence or absence of a pipeline within the valve body 100 can be quickly identified.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
