[0040] like Figures 1 to 5 As shown, this embodiment provides a disassembly device 100, which includes a plurality of positioning members 110, each positioning member 110 is provided with a handle 113 and a positioning groove 1100, and the plurality of positioning members 110 can be magnetically connected so that the plurality of positioning grooves 1100 together form a positioning cavity Q, and the positioning cavity Q can accommodate at least a portion of the part A to be disassembled, and the positioning cavity Q is adapted to the shape of at least a portion of the part A to be disassembled, so that the handle 113 can drive the part A to be disassembled to rotate when it rotates. In this embodiment, the positioning cavity Q can accommodate a partial structure of the part A to be disassembled, and at this time, the positioning cavity Q is adapted to the shape of the partial structure of the part A to be disassembled. In other embodiments, the positioning cavity Q can also accommodate the entire part A to be disassembled, and at this time, the positioning cavity Q is adapted to the shape of the part A to be disassembled.

[0041] The part A to be removed can be the male connector A of the connector 1 or female A 2 For example, the part A to be disassembled may be the male end A of the Luer connector. 1 or female A 2 The Luer connector can connect two medical devices, for example, Figure 2 As shown, the infusion device B of the interventional blood pump is connected to the infusion tube C through the Luer connector, wherein the female end A of the Luer connector 2 Connect to infusion set B, male end of Luer connector A 1 Connect to the infusion tube C, or the female end of the Luer connector A2 Can be connected to the infusion tube C of the interventional blood pump, the male end A of the Luer connector 1 It can be connected to the infusion set B. The following uses the female end A of the Luer connector as an example. 2 Connect to the infusion set B of the interventional blood pump, the male end A of the Luer connector 1 Taking the connection with the infusion tube C of the invasive blood pump as an example, the working process of the disassembly device 100 is described. Figure 2 As shown, the male end of the Luer connector A 1 The outside of the 3 .

[0042] like Figure 2 As shown, in this embodiment, the positioning cavity Q can accommodate the male head A of the part A to be removed. 1 and male A 1 The external protrusion A 3 , and the positioning cavity Q and the male connector A of the part to be removed 1 and convex A 3 In other embodiments, the positioning cavity Q can also accommodate the entire part A to be disassembled, and the positioning cavity Q is adapted to the shape of the entire part A to be disassembled.

[0043] It should be noted that the disassembly part A used by the disassembly device 100 may also be other types of connectors, such as a connector on an implantable ventricular assist device, and the disassembly part A may also be the male connector A of the connector. 1 or female A 2 , but the male A 1 With female connector A 2 The specific structure of the Luer connector is different from that of the Luer connector.

[0044] When using the disassembly device 100, first place each positioning member 110 of the disassembly device 100 close to the male connector A. 1 And each positioning piece 110 is placed along the male head A 1 Then, all the positioning members 110 are magnetically attracted together so that the male end A of the Luer connector 1 The locating member 110 is limited in the locating cavity Q formed by the cooperation between all the locating members 110. Then, the operator rotates the handle 113, and the locating member 110 rotates synchronously with the handle 113, thereby driving the male end A of the Luer connector. 1 Rotate the male connector A 1 Relative to female connector A 2 Wait for the male end of the Luer connector to become loose. 1 With female connector A 2 After separation, the positioning member 110 can be directly removed from the male end A of the Luer connector. 1 Remove from top.

[0045] The disassembly device 100 includes a plurality of positioning members 110, each positioning member 110 is provided with a handle 113 and a positioning groove 1100, and the plurality of positioning members 110 can be connected by magnetic attraction, so that the plurality of positioning grooves 1100 together form a positioning cavity Q. The positioning cavity Q can accommodate at least part of the part A to be disassembled, and the positioning cavity Q is adapted to the shape of at least part of the part A to be disassembled. Therefore, when the disassembly device 100 is used to disassemble the part A to be disassembled, the cavity wall of the positioning cavity Q formed by the plurality of positioning grooves 1100 can be sleeved on the outer periphery of the part A to be disassembled, and the operator can drive the part A to be disassembled to rotate by rotating the handle 113 to realize the disassembly of the part A to be disassembled. Among them, the provision of the handle 113 can facilitate the operator to apply force to the disassembly device 100, which can greatly reduce the difficulty of disassembling the part A to be disassembled; the plurality of positioning members 110 can be connected by magnetic attraction through the magnet 112, and the disassembly device 100 can be quickly matched and separated from the part A to be disassembled, which can improve the convenience of use of the disassembly device 100.

[0046] Specifically, the positioning member 110 includes a seat 111, a magnet 112 is disposed in the seat 111, and a plurality of seat 111 can be connected and fixed by magnetic attraction, so that a plurality of positioning grooves 1100 form a positioning cavity Q. In this embodiment, each positioning member 110 is provided with a magnet 112, so that a plurality of positioning members 110 can be connected by magnetic attraction, and the seat 111 can be a non-magnetic metal member, for example, hard plastic, etc. The plurality of seat 111 is magnetically attracted by the corresponding magnet 112.

[0047] Alternatively, a portion of the positioning members 110 is provided with a magnet 112, and another portion of the positioning members 110 is a magnetic conductive metal member that can be attracted by the magnet 112, so that the plurality of positioning members 110 can be magnetically attracted and connected. The magnetic conductive metal member can be made of pure iron, an iron-cobalt alloy, a soft ferrite, etc. These magnetic conductive metal members can be magnetically attracted to the magnet 112 in the seat 111, thereby realizing the magnetic attraction connection of the plurality of positioning members 110, so as to assemble and form the disassembly device 100.

[0048] The positioning groove 1100 of the positioning member 110 includes a main body 1101 and a narrow and long portion 1102 connected to the main body 1101. The main body 1101 can be sleeved on the outer peripheral surface of the to-be-disassembled part A. The narrow and long portion 1102 extends from the main body 1101 toward the handle 113 and can be provided for the protrusion A on the outer peripheral surface of the to-be-disassembled part A. 3 The contour of the narrow and long portion 1102 can be aligned with the protrusion A on the part to be disassembled A. 3The contour formed by the plurality of main body parts 1101 may be consistent with the main structure of the to-be-detached component A or inconsistent with it, as long as the contour formed by the plurality of main body parts 1101 can surround the main structure of the to-be-detached component A. The narrow portion 1102 extends from the main body part 1101 toward the handle 113, and the distance from the positioning groove 1100 to the edge of the seat body 111 can be increased from L to 1 Increase to L 2 (like Figure 4 As shown), the seat body 111 is stronger when the positioning cavity Q is formed by punching, the probability of damage to the seat body 111 when the positioning cavity Q is formed by punching is reduced, and the force is better received. In addition, the appearance consistency of the disassembly device 100 is better.

[0049] The magnet 112 can be made of magnetic materials such as aluminum-nickel-cobalt, iron-chromium-cobalt, and permanent ferrite. Compared with the method of setting the seat body 111 as a magnetic material as a whole, this embodiment uses the magnet 112 to achieve the magnetic attraction of the positioning member 110, so that the force between the multiple positioning members 110 is not very large, and the multiple positioning members 110 of the disassembly device 100 can be more conveniently disassembled, thereby facilitating the disassembly device 100 from the component A to be disassembled. It should be noted that the magnetic pole distribution of the magnet 112 can be set accordingly according to the specific situation, as long as all the disassembly components 110 can be magnetically attracted.

[0050] The seat body 111 includes an end face 1111 and an outer peripheral surface 1112 connected to the end face 1111. The positioning groove 1100 is arranged on the seat body 111 and passes through the end face 1111. The end faces 1111 of multiple seat bodies 111 can be connected to each other so that the multiple positioning grooves 1100 are spliced ​​to form a positioning cavity Q. The handle 113 is protruded from the outer peripheral surface 1112.

[0051] In this embodiment, if Figures 1 to 5 As shown, the number of the positioning members 110 can be two. In this way, the structure of the disassembly device 100 can be simplified by reducing the number of the positioning members 110, which facilitates the production and processing of the disassembly device 100. In other embodiments, the number of the positioning members 110 can also be three or more, which can be set according to actual conditions.

[0052] In this embodiment, the structure of each disassembly device 100 may be the same, so that all positioning members 110 can be manufactured by the same process, simplifying the manufacturing process of the disassembly device 100. The structure of the disassembly device 100 is described below.

[0053] In this embodiment, if Figure 5 As shown, the end face 1111 may be a plane, and the central axis of the seat body 111 is parallel to the end face 1111. It should be noted that the extension direction of the central axis of the seat body 111 is the axial direction of the seat body 111, and the axial direction of the seat body 111 is Figure 1 When two adjacent positioning members 110 are magnetically attracted, the end faces 1111 are planes, so that the end faces 1111 of two adjacent base bodies 111 are in surface contact, and the central axis of the base body 111 is parallel to the end faces 1111, so that when the operator acts on multiple positioning members 110, the multiple end faces 1111 that are connected to each other are offset, and it is difficult to generate a component force parallel to the direction of the end faces 1111 to cause the multiple positioning members 110 to be misaligned, so that the connection strength between the two adjacent positioning members 110 can be increased, so that when force is applied to the disassembly device 100, the multiple positioning members 110 are not easily separated.

[0054] In this embodiment, if Figure 5 As shown, the seat body 111 is cylindrical, and the seat body 111 further includes a top surface 1113 and a bottom surface 1114 opposite to each other along the axial direction of the seat body 111, and the end surface 1111 and the outer peripheral surface 1112 are both located between the top surface 1113 and the bottom surface 1114; the positioning groove 1100 also passes through the top surface 1113 and the bottom surface 1114. It should be noted that the axial direction of the seat body 111 is as shown in FIG. Figure 1 The axial direction shown is the standard.

[0055] By passing the positioning groove 1100 through the top surface 1113 and the bottom surface 1114 of the seat body 111, the positioning cavity Q can pass through the two end surfaces of the disassembly device 100 along the axial direction of the seat body 111, so that the male plugs A with different axial lengths can be 1 or female A 2 Limit the position, even if the male connector A 1 or female A 2 The axial length of the male connector A is too large. 1 or female A 2 The middle part of the can also be limited in the positioning cavity Q, without the need to follow the male A 1 or female A 2 The axial length of the seat body 111 is set to correspond to the specific axial length of the seat body 111, so as to expand the applicable scope of the disassembly device 100.

[0056] like Figure 5 As shown, there is a smooth transition between the outer peripheral surface 1112 and the top surface 1113 and between the outer peripheral surface 1112 and the bottom surface 1114, the handle 113 is a non-angular structure, and there is also a smooth transition between the handle 113 and the outer peripheral surface 1112. This arrangement can ensure that there are no sharp edges on the entire disassembly device 100, which can avoid scratching the operator.

[0057] As an example, rounded corners are provided between the outer peripheral surface 1112 and the top surface 1113 and between the outer peripheral surface 1112 and the bottom surface 1114 .

[0058] It should be noted that a non-angular structure refers to a structure without sharp edges. Figure 1As shown, the handle 113 may include a first surface 1131, a second surface 1132, and a side surface 1133 disposed opposite to each other along the axial direction of the base 111. The first surface 1131, the second surface 1132, and the side surface 1133 of the handle 113 have no sharp edges, and the first surface 1131 and the side surface 1133 of the handle 113 and the second surface 1132 and the side surface 1133 of the handle 113 have smooth transitions, such as rounded corners. The handle 113 of this structure can be regarded as a structure without edges and corners.

[0059] In this embodiment, if Figure 5 As shown, the seat 111 is further provided with a mounting hole 111b for mounting the magnet 112, and the mounting hole 111b passes through at least one of the end surface 1111 and the outer peripheral surface 1112. Compared with the method of arranging the magnet 112 on the end surface 1111, the magnet 112 is arranged in the mounting hole 111b of the seat 111, and this installation method can reduce the risk of the magnet 112 falling off.

[0060] Each positioning member 110 has a plurality of mounting holes 111b and magnets 112. The plurality of mounting holes 111b are disposed on opposite sides of the positioning groove 1100, and each magnet 112 is disposed in a corresponding mounting hole 111b. This arrangement can prevent the male connector A from being loosened. 1 or female A 2 The number of the mounting holes 111b and the magnets 112 can be set according to the specific situation. For example, the number of the mounting holes 111b and the magnets 112 is 2, and the two mounting holes 111b are symmetrically arranged on opposite sides of the handle 113, and each magnet 112 is arranged in the corresponding mounting hole 111b.

[0061] Further, in this embodiment, if Figure 5 As shown, the mounting hole 111b has a bottom wall 1115 adjacent to the end surface 1111 and an opening 1116 penetrating the outer peripheral surface 1112. The magnet 112 is disposed in the mounting hole 111b and is stopped by the bottom wall 1115 to prevent the fixed magnet 112 from falling into the positioning cavity Q. It should be noted that the magnet 112 can be installed in the mounting hole 111b through the opening 1116 of the mounting hole 111b.

[0062] like Figure 5As shown, the positioning member 110 further includes a hole plug 114, which is disposed at an opening 1116 of the mounting hole 111b, and the magnet 112 is mounted in the mounting hole 111b. Specifically, the magnet 112 is disposed between the hole plug 114 and the bottom wall 1115. By providing the hole plug 114, it is possible to prevent external dust and other pollutants from entering the mounting hole 111b, and it is also possible to prevent the magnet 112 from escaping from the mounting hole 111b through the opening 1116 of the mounting hole 111b. The magnet 112 can abut against the hole plug 114 and the bottom wall 1115 to prevent the magnet 112 from shaking in the mounting hole 111b.

[0063] The surface of the hole plug 114 away from the magnet 112 is the outer surface 1141, and the outer surface 1141 smoothly transitions with the outer peripheral surface 1112 of the seat body 111, so that the outer surface 1141 of the hole plug 114 and the part of the outer peripheral surface 1112 of the seat body 111 adjacent to the mounting hole 111b can cooperate to form an arc surface without obvious bumps, which can not only avoid scratching the operator, but also increase the appearance consistency of the disassembly device 100.

[0064] like Figure 4 As shown, in this embodiment, the positioning member 110 is a symmetrical structure and has a symmetry axis P, and the handle 113 extends along the symmetry axis P, so that the seat body 111 can be subjected to torques of equal magnitude and opposite directions, that is, the force on the seat body 111 is more uniform, which helps to reduce the probability of circumferential misalignment of the positioning member 110 during rotation.

[0065] It should be noted that when the operator's hand twists the disassembly device 100, if the hand simultaneously holds the base 111 of each positioning member 110, all positioning members 110 can rotate synchronously as a whole, and no circumferential misalignment will occur during the rotation process. However, when only the handle 113 on each positioning member 110 is pulled, that is, the operator's hand does not touch the base 111 of each positioning member 110, at least a part of the positioning members 110 may be circumferentially misaligned during the rotation process. For this, the magnitude of the magnetic attraction between the positioning members 110 needs to be limited. Specifically, the male head A of the part A to be disassembled 1 With female connector A 2 When plugged in, there is a tightening force. When the positioning members 110 are magnetically attracted, there is a magnetic attraction force, which is greater than the tightening force. It can be understood that the male connector A of the part to be removed 1 With female connector A 2 The tighter the screws are, the greater the fastening force of the part A to be disassembled is, and the greater the force applied by the operator to the disassembly device 100 is. The fastening force is equivalent to the force applied by the operator to the disassembly device 100. When the magnetic attraction between all the positioning members 110 is greater than the male head A of the part A to be disassembled, 1 With female connector A 2When the tightening force is applied, the circumferential misalignment of the positioning member 110 when the handle 113 is screwed can be avoided, thereby ensuring that the part A to be removed can be removed.

[0066] Example 2

[0067] like Figure 6 As shown, this embodiment provides a disassembly device. Different from the disassembly device 100 provided in Embodiment 1, a limiting structure is provided between adjacent positioning members 210 in the disassembly device. The limiting structure can also prevent the positioning member 210 from being circumferentially misaligned when the handle 213 is screwed.

[0068] like Figure 7 As shown, in this embodiment, the end face 2111 of the seat body 211 of one of the two adjacent positioning members 210 is provided with a limiting protrusion 2115, and the end face 2111 of the seat body 211 of the other one is provided with a limiting groove 211c. When the multiple positioning members 210 are magnetically attracted and connected, the limiting protrusion 2115 cooperates with the limiting groove 211c. Specifically, the limiting protrusion 2115 is arranged in the limiting groove 211, which can avoid circumferential misalignment of the positioning members 210 when the handle 213 is screwed, thereby further increasing the connection strength between the multiple positioning members 210.

[0069] Example 3

[0070] like Figures 8 to 10 As shown, this embodiment provides a disassembly device, which includes a plurality of positioning members 310, each positioning member 310 includes a seat body 311 and a magnet 312 arranged in the seat body 311, the seat body 311 includes an end face 3111 and an outer peripheral surface 3112 connected to the end face 3111, the seat body 311 is also provided with a mounting hole 311b passing through the outer peripheral surface 3112, and the mounting hole 311b has a bottom wall 3115 adjacent to the end face 3111 and an opening 3116 passing through the outer peripheral surface 3112.

[0071] Different from the disassembly device 100 provided in Example 1, the bottom wall 3115 of the positioning piece 310 of the disassembly device provided in this embodiment is provided with a through hole 3117 connected to the mounting hole 311b, and the diameter of the through hole 3117 is smaller than the diameter of the magnet 312, so that the magnet 312 can be exposed from the end face 3111, which can increase the magnetic attraction between the magnets 312 of adjacent positioning pieces 310, thereby increasing the connection strength between adjacent positioning pieces 310.

[0072] In this embodiment, the magnet 312 can abut between the hole plug 314 and the bottom wall 3115, so that the magnet 312 can be clamped between the hole plug 314 and the bottom wall 3115, which can prevent the magnet 312 from shaking in the mounting hole 311b.

[0073] Example 4

[0074] like Fig.11 As shown, this embodiment provides a disassembly device, which includes a plurality of positioning members 410, each positioning member 410 includes a seat body 411 and a magnet 412 arranged in the seat body 411, the seat body 411 includes an end face 4111 and an outer peripheral surface 4112 connected to the end face 4111, and the seat body 411 is also provided with a mounting hole 411b passing through the outer peripheral surface 4112.

[0075] Different from the disassembly device 100 provided in Example 1, the mounting hole 411b of the disassembly device of this embodiment has a bottom wall 4115 adjacent to the outer peripheral surface 4112 and an opening 4116 penetrating the end surface 4111. In this embodiment, the mounting hole 411b can be a blind hole, that is, the mounting hole 411b only penetrates the end surface 4111 and does not penetrate the outer peripheral surface 4112. The magnet 412 is interference fit with the hole wall of the mounting hole 411b, and the side of the magnet 412 away from the bottom wall 4115 is the suction surface 412a, which is located at the opening 4116 and flush with the end surface 4111. In this way, the magnets 412 of the positioning member 410 are prevented from being affected by the end surface 4111, thereby increasing the connection strength between adjacent positioning members 410.

[0076] It should be noted that the interference fit between the magnet 412 and the mounting hole 411 b should be greater than the magnetic attraction between the magnets 412 to prevent the magnet 412 from falling off from the mounting hole 411 b.

[0077] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
