The first connecting block 231 and the second connecting block 232 are driven to approach each other so that the first connecting block 231 and the second connecting block 232 can be buckled together and surround a positioning hole 233. The connector 120 is arranged to pass through the positioning hole 233 so that the connector 120 can be fixed on the fixing plate 210 without being fixed by tape, thereby improving the convenience of use, avoiding the shaking of the position of the infusion tube, and improving the fixation of the indwelling needle body 110.

[0030] It is understandable that, referring to Figures 1 to 3 The first connection block 231 is provided with a clamping block 234, and the second connection block 232 is provided with a connection plate 235. The connection plate 235 is provided with a connection hole 236, and the clamping block 234 can be clamped into the connection hole 236. The clamping block 234 is arranged on the first connection block 231, and the connection plate 235 is arranged on the second connection plate 235. By driving the first connection block 231 and the second connection block 232 to approach each other, so that the clamping block 234 is clamped into the connection hole 236, the first connection block 231 and the second connection block 232 can be quickly connected together, so that the first connection block 231 and the second connection block 232 can surround the positioning hole 233 to limit the position of the joint 120, reduce the shaking of the position of the joint 120, reduce the possibility of the indwelling needle body 110 falling off, and improve the safety of use.

[0031] Specifically, refer to Figures 1 to 3A torsion spring 237 is provided between the second connecting block 232 and the connecting plate 235 . The connecting plate 235 is rotatably connected to the second connecting block 232 . The torsion spring 237 is used to drive the connecting plate 235 to rotate. The connecting plate 235 is rotatably connected to the second connecting block 232, one end of the torsion spring 237 abuts against the connecting plate 235, and the other end abuts against the second connecting block 232, and the connecting plate 235 can be driven to rotate by the torsion spring 237 so that the connecting plate 235 can approach the first connecting block 231, and the connecting plate 235 is pressed so that the connecting plate 235 compresses the torsion spring 237, so that the connecting plate 235 moves in the direction away from the block 234, and then the first connecting block 231 and the second connecting block 232 are driven to approach each other so that the block 234 and the connecting hole 236 are arranged adjacent to each other, and then the connecting plate 235 is released, and the torsion spring 237 drives the connecting plate 235 to reset, and the block 234 is inserted into the connecting hole 236, so that the block 234 can abut against the side wall of the connecting hole 236, so that the first connecting block 231 and the second connecting block 232 can be quickly buckled together, so that the connector 120 can be quickly fixed in the positioning hole 233, thereby improving the convenience of use.

[0032] Specifically, refer to Figures 1 to 3 , the height dimension of the card block 234 gradually increases in the direction away from the second connection block 232. By setting the height dimension of the card block 234 to gradually increase in the direction away from the second connection block 232, the first connection block 231 and the second connection block 232 are driven to approach each other, so that the connection plate 235 can abut against the card block 234, and the connection plate 235 can be guided to rotate in the direction away from the card block 234, so that when the card block 234 is extended into the connection hole 236, the side wall of the connection hole 236 can automatically abut against the card block 234, so that the user does not need to press the connection plate 235 to rotate, which facilitates the first connection block 231 and the second connection block 232 to buckle together, thereby improving the positioning convenience of the joint 120.

[0033] It should be noted that the shape of the block 234 is a triangular prism, so that when the first connecting block 231 and the second connecting block 232 are close to each other, the connecting plate 235 can abut against the wall of the block 234 and can guide the connecting plate 235 to rotate in the direction away from the first connecting block 231 to compress the torsion spring 237, and then the block 234 extends into the connecting hole 236, and the torsion spring 237 drives the connecting plate 235 to reset, so that the side wall of the connecting hole 236 can abut against the block 234, so that the positions of the first connecting block 231 and the second connecting block 232 can be quickly located, thereby improving the positioning convenience of the connector 120.

[0034] Specifically, refer to Figure 2, the number of the block 234 and the connecting plate 235 is set to two, the block 234 and the connecting plate 235 are in one-to-one correspondence, and the two block 234 and the connecting plate 235 are respectively arranged on both sides of the second connecting block 232. The number of the block 234 and the connecting plate 235 is set to two, and by setting two block 234 and the connecting plate 235 to be respectively arranged on both sides of the second connecting block 232, the connection strength between the first connecting block 231 and the second connecting block 232 can be improved, the possibility of the block 234 sliding out of the connecting hole 236 can be reduced, the force of the first connecting block 231 and the second connecting block 232 is balanced, and the reliability of the connecting assembly 230 is improved. In addition, the force on a single block 234 and the connecting plate 235 can be reduced, so that the deformation of the block 234 and the connecting plate 235 can be reduced, and the reliability can be improved.

[0035] It is understandable that, referring to Figure 3 and Figure 4 , one side of the fixing plate 210 is rotatably connected with the adjusting plate 211, and the adjusting plate 211 can be buckled with the fixing plate 210, one end of the elastic band 220 is fixedly connected to the fixing plate 210, and the other end is passed between the fixing plate 210 and the adjusting plate 211. The adjusting plate 211 is rotated to separate the adjusting plate 211 from the fixing plate 210, and then the length of the elastic band 220 is adjusted, and then the adjusting plate 211 is buckled with the fixing plate 210, which can conveniently adjust the length of the elastic band 220, so that the elastic band 220 can adapt to the size of the patient's limbs, so that the elastic band 220 can conveniently fix the fixing plate 210 on the patient's limbs, and improve the accuracy of positioning.

[0036] It is understandable that, referring to Figure 3 and Figure 4 , the adjusting plate 211 is provided with a plurality of positioning blocks 212 protruding from one side of the fixing plate 210, and the fixing plate 210 is provided with a plurality of positioning grooves 213, and the positioning blocks 212 correspond to the positioning grooves 213 one by one. The adjusting plate 211 is provided with a plurality of positioning blocks 212 protruding from one side of the fixing plate 210, and the fixing plate 210 is provided with a plurality of positioning grooves 213 on one side of the fixing plate 210, and the positioning blocks 212 correspond to the positioning grooves 213 one by one. The adjusting plate 211 is buckled, so that the positioning blocks 212 can move toward the direction close to the positioning grooves 213, so that the elastic band 220 can be pressed into the positioning grooves 213, and the friction between the elastic band 220 and the fixing plate 210 is increased, so that the elastic band 220 can be stabilized on the fixing plate 210, and the position stability of the elastic band 220 is improved, and the possibility of the elastic band 220 being loosened is reduced, and the reliability is improved.

[0037] It is understandable that, referring to Figure 1The number of elastic bands 220 is set to be multiple, and the multiple elastic bands 220 are arranged at intervals on the fixing plate 210. By setting the number of elastic bands 220 to be multiple, the contact area between the elastic bands 220 and the patient is increased to prevent the elastic bands 220 from strangling the patient, and the multiple elastic bands 220 can improve the position stability of the fixing plate 210, so that the fixing plate 210 can be stabilized on the patient's limbs and reduce the possibility of loosening.

[0038] It is understandable that, referring to Figure 3 The side wall of the positioning hole 233 is wrapped with a rubber pad 238. By wrapping the rubber pad 238 on the side wall of the positioning hole 233, when the first connecting block 231 and the second connecting block 232 are buckled, the joint 120 can be positioned in the rubber pad 238, which can reduce the wear of the joint 120, increase the friction with the joint 120, reduce the position shaking of the joint 120, and improve the positioning accuracy of the joint 120.

[0039] It should be noted that the rubber pad 238 can be a rubber part or a silicone part, which will not be described in detail here.

[0040] It is understandable that, referring to Figure 1 and Figure 3 The fixing plate 210 is in an arc shape. By setting the fixing plate 210 in an arc shape, the fixing plate 210 can fit the patient's limbs, and the contact area between the fixing plate 210 and the patient can be increased, thereby improving the wrapping property of the fixing plate 210, reducing the position shaking of the fixing plate 210, and improving the position stability of the indwelling needle body 110.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
