Abstract

This utility model discloses a medical coupling agent extruder, relating to the field of medical coating technology, comprising: a medical outer cylinder for placing the medical coupling agent; a clamping component installed on the medical outer cylinder for clamping the flat, sealed end of the medical coupling agent; and an extruder comprising: a lifting device that reciprocates along the height direction of the medical outer cylinder. This device is equipped with a second elastic extrusion plate as a pre-extrusion structure and a first elastic extrusion plate as the final extrusion structure. The lifting mechanism drives the two sets of extrusion plates to move synchronously from the flat, sealed end of the hose to the nozzle. The lower extrusion plate first completes the pre-extrusion to gather the hose, fixing the coupling agent position to prevent slippage and backflow.

This allows the coupling agent inside the hose to be completely pushed to the outlet end, significantly reducing material residue inside the hose and improving the utilization rate of the coupling agent.

Description

Technical Field

[0001] This utility model relates to the field of medical coating technology, specifically to an extruder for a medical coupling agent. Background Technology

[0002] In clinical ultrasound examinations, medical coupling agents are often packaged in soft tubing, requiring medical staff to manually squeeze the tubing to expel the coupling agent. This manual expulsion method has several drawbacks: The squeezing force and application position are entirely controlled by manual feel, which can easily lead to localized over-squeezing, intermittent material output at the front end, and a large amount of coupling agent residue at the end of the tube, resulting in low material utilization. A single manual squeeze can only apply pressure to a single point, making it impossible to form a progressive squeeze. The coupling agent inside the tube is prone to backflow, and the material output is uneven after multiple squeezes, affecting the efficiency of ultrasonic coating operations. Repeated manual squeezing of the tube can easily cause hand fatigue, which can significantly increase the labor intensity of medical staff when examining a large number of patients. Most simple squeezing instruments on the market have a single squeezing surface structure without a layered pre-squeezing and final squeezing structure. The tube diameter cannot be gradually reduced during the squeezing process, and the sealing end of the thin tube is prone to slippage and compression slippage, making it difficult to completely push the coupling agent to the tube opening.

[0003] Existing extrusion equipment lacks a segmented progressive extrusion structure, and cannot first pre-tighten and limit the extrusion before closing and fully extruding. This results in a large amount of coupling agent residue inside the hose and poor material discharge stability, making it difficult to meet the fixed extrusion requirements of the flat sealing end of medical coupling agent hoses. Therefore, there is an urgent need for a medical coupling agent extruder with a two-stage progressive extrusion structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a squeezer for medical coupling agents.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A squeezer for a medical coupling agent, comprising: Medical outer tube, used for placing medical coupling agent; A clamping element, installed on the medical outer cylinder, is used to clamp the flat sealing end of the medical coupling agent; Extruded parts, comprising: The lifting device reciprocates along the height direction of the medical outer cylinder; A pair of inclined plates are symmetrically installed on both sides of the elevator in an inverted "V" shape; A pair of elastic compression plates, in an inverted "V" shape, are fixed to the end of the inclined plate away from the elevator. A pair of elastic compression plates are fixed in an inverted "V" shape at the end of the inclined plate away from the lifter, and the elastic compression plates are located below the elastic compression plates. The distance between the pair of elastic compression plates is smaller than the distance between the pair of elastic compression plates. in: The flat sealing end of the medical coupling agent is clamped onto the clamping device. The lifting device drives the inclined plate, elastic extrusion plate one, and elastic extrusion plate two to move synchronously from the flat sealing end of the medical coupling agent to the outlet end of the medical coupling agent. Elastic extrusion plate two constitutes the pre-extrusion structure of the medical coupling agent, and elastic extrusion plate one constitutes the final extrusion structure of the medical coupling agent.

[0006] Preferably, an angle adjustment assembly is provided between the inclined plate and the lifting plate. The angle adjustment assembly includes an adjustment screw and a locking nut. The inclined plate is hinged to the side of the lifting plate through the adjustment screw. Rotating the adjustment screw can simultaneously adjust the opening angle of the two inclined plates, so as to simultaneously change the overall clamping and squeezing width of the first elastic squeezing plate and the second elastic squeezing plate. The first elastic squeezing plate and the second elastic squeezing plate are both segmented elastic silicone plates, and thin metal spring sheets are embedded inside the plate body.

[0007] Preferably, the elastic extrusion plate two has multiple transverse anti-slip ridges on the side facing the coupling agent, and the elastic extrusion plate one has an arc-shaped extrusion surface on the side facing the coupling agent; the elastic extrusion plate one and the elastic extrusion plate two can be detachably inserted and fixed to the inclined plate, and the end of the inclined plate is provided with a positioning slot for the elastic extrusion plate to be inserted and removed.

[0008] Preferably, the lifting device includes a threaded rod and a lifting plate. The threaded rod is rotatably connected to the medical outer cylinder along the height direction of the medical outer cylinder, and the threaded rod is driven by a micro motor. The lifting plate is adapted to be connected to the threaded rod. The motor drives the threaded rod to rotate, thereby driving the lifting plate to reciprocate along the height direction of the medical outer cylinder.

[0009] Preferably, the clamping member includes a pair of clamping rotating plates, which are rotatably connected to the medical outer cylinder, and the pair of clamping rotating plates are connected together by a tension spring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This equipment is equipped with a second elastic extrusion plate as a pre-extrusion structure and a first elastic extrusion plate as the final extrusion structure. The lifting mechanism drives the two sets of extrusion plates to move synchronously from the flat sealing end of the hose to the nozzle. The lower extrusion plate first completes the pre-extrusion and gathers the hose, fixing the position of the coupling agent to prevent slippage and backflow. The upper extrusion plates have a smaller spacing to form a closing extrusion, compressing the hose diameter step by step. This can push the coupling agent in the hose completely to the outlet end, greatly reducing material residue in the hose and improving the utilization rate of the coupling agent.

[0013] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model. Example

[0014] like Figures 1-6 As shown, a squeezer for a medical coupling agent includes: Medical outer tube 1, used for placing medical coupling agent 4; Clamping member 2 is installed on the medical outer cylinder 1 and is used to clamp the flat sealing end of the medical coupling agent 4; The clamping member 2 includes a pair of clamping rotating plates 21, which are rotatably connected to the medical outer cylinder 1, and are connected together by a tension spring 22. Extruded part 3, comprising: The lifting device reciprocates along the height direction of the medical outer cylinder 1; The lifting device includes a threaded rod 31 and a lifting plate 32. The threaded rod 31 is rotatably connected to the medical outer cylinder 1 along the height direction of the medical outer cylinder 1, and the threaded rod 31 is driven by a micro motor. The lifting plate 32 is adapted to be connected to the threaded rod 31. The motor drives the threaded rod 31 to rotate, thereby driving the lifting plate 32 to reciprocate along the height direction of the medical outer cylinder 1. A pair of inclined plates 33 are symmetrically installed on both sides of the elevator in an inverted "V" shape; A pair of elastic compression plates 34 are fixed in an inverted "V" shape at the end of the inclined plate 33 away from the elevator; A pair of elastic compression plates 35 are fixed in an inverted "V" shape at the end of the inclined plate 33 away from the elevator, and the elastic compression plates 35 are located below the elastic compression plates 34. The distance between the pair of elastic compression plates 34 is smaller than the distance between the pair of elastic compression plates 35. in: The flat sealing end of the medical coupling agent 4 is clamped onto the clamping member 2. The lifting device drives the inclined plate 33, the first elastic extrusion plate 34, and the second elastic extrusion plate 35 to move synchronously from the flat sealing end of the medical coupling agent 4 to the outlet end of the medical coupling agent 4. The second elastic extrusion plate 35 constitutes the pre-extrusion structure of the medical coupling agent 4, and the first elastic extrusion plate 34 constitutes the final extrusion structure of the medical coupling agent 4.

[0015] Specifically, this medical coupling agent extruder uses the medical outer cylinder 1 as the overall support base. The clamping component 2 positions the end of the medical coupling agent 4 tubing, and the motor-driven extruder 3 completes a two-stage progressive automatic extrusion process. The clamping component 2, relying on a pair of clamping rotating plates 21 and a tension spring 22, forms a self-clamping structure that firmly secures the flat sealing end of the medical coupling agent 4, preventing tubing slippage during extrusion. The extruder 3 is powered by a lifting device, which consists of a threaded rod 31 and a lifting plate 32. A micro-motor drives the threaded rod 31 to rotate, converting the rotational motion into linear reciprocating motion of the lifting plate 32 along the height of the medical outer cylinder 1. Inverted "V"-shaped inclined plates 33 are symmetrically installed on both sides of the lifting plate 32. At the ends of the inclined plates 33, two elastic extrusion plates, one 34 and two 35, are layered. The second elastic extrusion plate 35 is located at the bottom with a larger gap between the two plates, forming a pre-extrusion structure. The first elastic extrusion plate 34 is located at the top with a smaller gap between the two plates, forming the final extrusion structure. When the lifting plate 32 drives the inclined plate 33, the first elastic extrusion plate 34, and the second elastic extrusion plate 35 to move synchronously from the flat sealing end of the medical coupling agent 4 to the outlet end, the lower elastic extrusion plate 35 first adheres to the hose to complete the initial gathering, preventing the coupling agent from flowing back. The upper elastic extrusion plate 34 follows closely behind, reducing the cross-section of the hose and pushing the coupling agent in the tube step by step. The gradient extrusion force is formed by the difference in the distance between the two extrusion plates. Combined with the elasticity of the extrusion plate itself to adhere to the outer wall of the hose, uniform discharge is achieved and the coupling agent residue in the tube is reduced. The entire process relies on mechanical transmission to replace manual extrusion.

[0016] The workflow is as follows: First, insert the tubing containing medical coupling agent 4 into the medical outer cylinder 1. Manually pry open the two clamping rotating plates 21 of the clamping component 2, stretch the tension spring 22 to keep the clamping rotating plates 21 open, place the flat sealing end of the medical coupling agent 4 between the two clamping rotating plates 21, release your hand, stretch the tension spring 22 to contract and pull the clamping rotating plates 21 to close, clamping and fixing the end of the tubing; Second, start the micro motor, the motor drives the threaded rod 31 to rotate, the lifting plate 32 sleeved on the threaded rod 31 moves upward along the height direction of the medical outer cylinder 1, the lifting plate 32 simultaneously drives the two inclined plates 33, elastic compression plate one 34, and elastic compression plate two 35 to move upward together; Third, during the movement, the elastic compression plate two 35 located on the lower layer... 5. First, contact the outer wall of the medical coupling agent 4 tubing to complete pre-compression, retract the tubing and prevent the coupling agent from flowing back to the tail. Simultaneously, the elastic compression plate 34 moves upward to close the tubing at a smaller interval, completing the final compression. The two sets of compression structures move synchronously from the flat sealing end of the tubing to the outlet end, gradually pushing the coupling agent inside the tube to the tube opening to complete the discharge. In the fourth step, after a single compression discharge is completed, control the micro motor to reverse, and the threaded rod 31 rotates in the opposite direction to drive the lifting plate 32, inclined plate 33, elastic compression plate 34, and elastic compression plate 35 to return to the initial position. In the fifth step, pry open the clamping rotating plate 21 again, release the used coupling agent tubing, replace it with a new medical coupling agent 4 tubing, and repeat the above process to continuously carry out the automatic extrusion operation of the coupling agent.

[0017] Furthermore, an angle adjustment assembly is provided between the inclined plate 33 and the lifting plate 32. The angle adjustment assembly includes an adjusting screw and a locking nut. The inclined plate 33 is hinged to the side of the lifting plate 32 via the adjusting screw. Rotating the adjusting screw can simultaneously adjust the opening angle of the two inclined plates 33, thereby simultaneously changing the overall clamping and squeezing width of the first elastic squeezing plate 34 and the second elastic squeezing plate 35. The first elastic squeezing plate 34 and the second elastic squeezing plate 35 are both segmented elastic silicone plates, with thin metal spring sheets embedded inside the plates. The second elastic squeezing plate 35 has multiple transverse anti-slip ridges on the side facing the coupling agent, and the first elastic squeezing plate 34 has an arc-shaped constricting squeezing surface on the side facing the coupling agent. The first elastic squeezing plate 34 and the second elastic squeezing plate 35 can be detachably inserted and fixed to the inclined plate 33. The end of the inclined plate 33 has a positioning slot for the insertion and removal of the elastic squeezing plates.

[0018] Specifically, the angle adjustment component, improved elastic compression plate, and detachable plug-in structure added in this section are used to adapt to medical coupling agent 4 tubing of different diameters and improve compression fit, anti-slip, and discharge effects. The inclined plate 33 and lifting plate 32 are hinged together by an adjusting screw and a locking nut to form the angle adjustment component. Rotating the adjusting screw can simultaneously change the opening angle of the inclined plates 33 on both sides, thereby simultaneously adjusting the overall clamping and compression width of the elastic compression plates 34 and 35 to adapt to the compression requirements of coupling agent tubing of different diameters. The locking nut can lock the position of the adjusting screw to ensure that the angle of the inclined plate 33 will not shift on its own during compression. The elastic compression plates 34 and 35 are made of segmented elastic silicone material with embedded thin metal springs, possessing both the characteristics of flexible fit between silicone and the outer wall of the tubing and no damage to the tubing. Furthermore, the metal spring sheet provides stable support, preventing excessive deformation of the extrusion plate and loss of extrusion force. The inner side of the second elastic extrusion plate 35 is equipped with multiple transverse anti-slip ridges to increase the friction with the outer wall of the hose, effectively preventing the hose from slipping and moving axially during the pre-extrusion stage. The inner side of the first elastic extrusion plate 34 is designed with an arc-shaped extrusion surface, which closes the hose during the final extrusion, allowing the coupling agent to gather and flow smoothly. At the same time, the ends of the first elastic extrusion plate 34, the second elastic extrusion plate 35, and the inclined plate 33 adopt a positioning slot plug-in detachable connection structure, which makes it easy to disassemble and replace the extrusion plate after wear without replacing the entire inclined plate 33, thus reducing the cost of use and maintenance.

[0019] In practical operation, first loosen the locking nut of the angle adjustment component according to the required diameter of the medical coupling agent 4 hose used on site. Rotate the adjustment screw to drive the two inclined plates 33 to rotate synchronously around the hinge point, adjusting the opening amplitude of the inclined plates 33. This changes the overall compression width between the first elastic compression plate 34 and the second elastic compression plate 35. After adjusting to the size suitable for the outer diameter of the hose, tighten the locking nut to lock the angle of the inclined plates 33 and prevent angle changes during operation. If the first elastic compression plate 34 and the second elastic compression plate 35 show signs of aging and wear, the compression plates can be directly pulled out from the positioning slots at the ends of the inclined plates 33 and replaced with brand new segmented elastic silicone compression plates. The thin metal spring inside the plate maintains the rigidity of the extrusion plate, and the assembly is completed by inserting it back into the slot. When the equipment is in formal extrusion operation, the elastic extrusion plate 2 35 with transverse anti-slip ridges first adheres to the outer wall of the hose to complete the pre-extrusion. The ridges increase friction to prevent the hose from slipping. As the lifting plate 32 moves upward, the elastic extrusion plate 1 34 with an arc-shaped extrusion surface on the inner side simultaneously contacts the hose. The arc structure closes the hose cross-section to complete the final extrusion. The flexible silicone material, together with the internal metal spring, continuously outputs stable extrusion force. After extrusion is completed and the system is reset, if it is necessary to replace the coupling agent hose of different specifications, the steps of loosening the locking nut and adjusting the angle of the inclined plate 33 can be repeated to adapt it for use.

[0020] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
