[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1 to 4 As shown, the suction tube head welding fixture of this utility model includes: a first plate 1 having a first accommodating hole 11 extending along a first direction; a second plate 2 having a second accommodating hole 21 extending along the first direction and coaxial with the first accommodating hole 11; a tensioning member 3 having a first end and a second end opposite to each other, the first end passing through the second accommodating hole 21 and entering between the first plate 1 and the second plate 2, the outer diameter of the tensioning member 3 being smaller than the inner diameter of the second accommodating hole 21; and a heating assembly 4 disposed between the first plate 1 and the second plate 2, the heating assembly 4 being able to heat and melt the suction tube head and body sleeved on the tensioning member 3.

[0025] See Figure 1 The first direction is the direction in which the first plate 1 and the second plate 2 move towards each other or away from each other. The first inlet 11 of the first plate 1 is used to place the tube body of the suction tube, and the second inlet 21 of the second plate 2 is used to place the tube head of the suction tube.

[0026] See Figure 1 , Figure 3 , Figure 4 The tensioning member 3 has a first end and a second end. The tensioning member 3 is disposed in the second accommodating hole 21. The first end of the tensioning member 3 is located between the first plate 1 and the second plate 2, and the second end of the tensioning member 3 is located on the side of the second plate 2 away from the first plate 1.

[0027] Specifically, when welding the tube body and tube head of the suction catheter, firstly, the tube head is passed through the first end of the tensioning member 3, and at least partially located within the second accommodating hole 21 of the second plate 2. Then, the tube body is placed within the first accommodating hole 11 of the first plate 1. Subsequently, the first plate 1 and the second plate 2 are controlled to move towards each other, allowing the tube body on the first plate 1 to enter the first end of the tensioning member 3 and contact the tube head. Finally, the heating assembly 4 located between the first plate 1 and the second plate 2 is used to heat the tube body and tube head on the tensioning member 3. The tube body and tube head are heat-fused. After the tube body and tube head are heat-fused, the first plate 1 can be controlled to move closer to the second plate 2 or the second plate 2 can move closer to the first plate 1 to squeeze the heat-fused part of the tube body and tube head. After the tube body and tube head of the suction tube cool down, the tube head and tube body of the suction tube can be fused together. The inner ring of the tube body and tube head is supported by the tensioning member 3, which can effectively reduce the change in shape of the tube body and tube head during heat fusion, improve the fusion quality of the tube body and tube head of the suction tube in this application, reduce the difficulty of subsequent secondary processing, and has practicality.

[0028] In one or more embodiments, the heating assembly 4 includes a first heat-melting element 41 and a second heat-melting element 42 that are movably disposed on the second plate 2 along a second direction. The first heat-melting element 41 and the second heat-melting element 42 have notches adapted to the second accommodating hole 21, and a heating element for heating the tube head and the tube body is disposed in the notch.

[0029] See Figure 1 , Figure 3 The second direction is the width direction of the second plate 2.

[0030] See Figure 3 Both the first hot melt element 41 and the second hot melt element 42 have semi-circular notches. When the first hot melt element 41 and the second hot melt element 42 abut against each other, the two notches form a circular shape. The diameter of the circular hole is at least larger than the diameter of the second accommodating hole 21. Heating components are arranged in the notches of the first hot melt element 41 and the second hot melt element 42 to form comprehensive heating of the opposite parts of the tube body and the tube head. The heating components can be heating wires or hot air holes through which hot air flows.

[0031] When heating the opposite ends of the tube head and tube body, the first hot melt element 41 and the second hot melt element 42 are controlled to move towards each other on the second plate 2 so that the first hot melt element 41 and the second hot melt element 42 abut against each other, so that the two notches form a circular hole structure, allowing the tube body and tube head to be surrounded by the heating element. Then, the opposite ends of the tube body and tube head can be heated by the heating element. It has the characteristics of simple structure, convenient operation and high heating efficiency.

[0032] In one or more embodiments, a first plate 1 and a second plate 2 are disposed on a base 5 along a first direction. The first plate 1 is driven along the first direction by a first driving device 6 disposed on the base 5, and the second plate 2 is driven along the first direction by a second driving device 7 disposed on the base 5. See also Figure 1 The first driving device 6 and the second driving device 7 can be a driving cylinder, a lead screw module or other possible driving source, and there are no specific restrictions.

[0033] In one or more embodiments, the cross-section of the first end of the support member 3 is a frustum structure. This arrangement facilitates the insertion of the tube body placed on the first plate 1 into the first end of the support member 3, improves the heat fusion efficiency of the suction tube body and tube head, and is practical.

[0034] In one or more embodiments, the second end of the tensioning member 3 is mounted on the adapter plate 81, which is movably mounted on the second plate 2 away from the first plate 1 by means of the elastic member 82 along the first direction.

[0035] See Figure 1 , Figure 4 By placing the second end of the tensioning member 3 on the adapter plate 81 and connecting the adapter plate 81 to the second plate 2 via the elastic member 82, the tensioning member 3 can move within the second accommodating hole 21 along the axial direction of the second accommodating hole 21. After the tube body and tube head of the suction tube have been fused and cooled, pressing the adapter plate 81 allows the tensioning member 3 to move within the suction tube, reducing the problem of the tube body and tube head of the suction tube sticking to the tensioning member 3 and being difficult to remove.

[0036] In one or more embodiments, the outer surface of the support member 3 is coated with a polytetrafluoroethylene (PTFE) coating. It should be noted that the PTFE coating has a certain self-lubricating effect, which can further reduce the possibility that the suction tube head and body will stick to the support member 3 after heat fusion, making it easier for staff to remove the fused suction tube from the support member 3.

[0037] In one or more embodiments, the top surface of the first plate 1 is provided with a first channel communicating with the first accommodating hole 11 in the vertical direction, and a first screw 91 is screwed into the first channel; the top surface of the second plate 2 is provided with a second channel communicating with the second accommodating hole 21 in the vertical direction, and a second screw 92 is screwed into the second channel.

[0038] See Figures 1 to 4 When it is necessary to weld the body and head of a suction catheter with a smaller diameter, a first round tube can be placed in the first accommodating hole 11 and the bottom end of the first screw 91 can be used to press the first round tube against the hole. A second round tube can be placed in the second accommodating hole 21 and the bottom end of the second screw 92 can be used to press the second round tube against the hole. This arrangement can improve the processing range of suction catheters in this application.

[0039] In one or more embodiments, the first plate 1 has an extension tube 12 disposed on the surface away from the second plate 2, the extension tube 12 is coaxial with the first accommodating hole 11, and the inner diameter of the extension tube 12 is greater than or equal to the inner diameter of the first accommodating hole 11.

[0040] See Figure 1 , Figure 2 The extension tube 12 is used to place the suction tube body on the side away from the tube head, reducing the possibility of the suction tube body shifting within the first accommodating hole 11 and improving the welding quality of the suction tube in this application.

[0041] In one or more embodiments, the elastic element 82 is a spring or elastic steel.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
