Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a retention needle which is easy to move. Background Art

[0002] In modern medical practice, for patients who need frequent intravenous injections or blood draws, traditional single-use needles can no longer meet clinical needs. In order to reduce patients' pain, reduce skin damage and improve work efficiency, the medical community is constantly pursuing more humane, safe and effective infusion and blood collection methods, so a retention needle that can be easily moved is needed. Utility Model Content

[0003] The utility model provides a retention needle which is easy to move and overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problem is:

[0005] A retention needle that is easy to move, comprising an insertion needle, an infusion tube, a retention tube body, and a fixing assembly, wherein the insertion needle is connected to the retention tube body through the infusion tube, and the fixing assembly is sleeved outside the retention tube body, and the retention tube body is wrapped around the wrist through the fixing assembly;

[0006] The insertion needle comprises a soft needle and a grabbing piece. The soft needle is connected to the infusion tube through the grabbing piece, and the soft needle is connected to the grabbing piece through a rubber hose.

[0007] A preferred technical solution: The fixing component includes a fixing shell and a rubber sheet. The fixing shell is sleeved outside the retention tube body, and the rubber sheet is connected to the side of the fixing shell. When the retention tube body is fixed on the wrist through the fixing component, the rubber sheet wraps around the wrist and is connected to the fixing shell to form a fixation.

[0008] A preferred technical solution: two buckle blocks are provided on the upper surface of the fixed shell, and two corresponding notches are provided at the end of the rubber sheet. After the rubber sheet is wrapped around the wrist, the buckle blocks are embedded in the notches to be fixed.

[0009] A plurality of anti-sliding blocks are equidistantly arranged on both side edges of the rubber sheet, and the anti-sliding blocks are arranged along the length direction of the rubber sheet.

[0010] Compared with the prior art, this technical solution has the following advantages:

[0011] The rubber hose in the present invention is made of rubber material, and a plurality of inwardly recessed step edges are equidistantly arranged on the surface along the axial direction. The step edges are used to facilitate deformation of the rubber hose when subjected to force. Based on this design, after the soft needle is inserted, the patient's limb movement drives the soft needle to be subjected to force, so that the soft needle and the grabbing piece can swing and move with the rubber hose as a fulcrum, thereby avoiding the retention needle in the prior art, where the soft needle will penetrate deeper into the vein during limb movement, causing discomfort to the patient. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0013] Figure 1 It is a schematic diagram of the overall structure of the utility model.

[0014] Figure 2 It is a schematic diagram of fixing component 4.

[0015] In the figure: a pin 1, a soft needle 11, a rubber hose 111, and a grabbing piece 12;

[0016] Infusion tube 2;

[0017] Retention tube body 3;

[0018] The fixing assembly 4 , the fixing shell 41 , the buckle block 411 , the anti-sliding block 412 , the rubber sheet 42 , the notch 421 , and the anti-sliding block 422 . DETAILED DESCRIPTION

[0019] A retention needle that is easy to move, including an insertion needle 1, an infusion tube 2, a retention tube body 3, and a fixing component 4. The insertion needle 1 is connected to the retention tube body 3 through the infusion tube 2, and the fixing component 4 is sleeved outside the retention tube body 3, and the retention tube body 3 is wrapped around the wrist through the fixing component 4. The insertion needle 1 includes a soft needle 11 and a grabbing piece 12. The soft needle 11 is connected to the infusion tube 2 through the grabbing piece 12, and the soft needle 11 is connected to the grabbing piece 12 through a rubber hose 111. It can be seen that when the retention needle in the present invention is used, the soft needle 11 can be moved. Inserted into the vein to output the drug solution, the rubber hose 111 in the present invention is made of rubber material, and the surface is equidistantly provided with a plurality of inwardly recessed step edges along the axial direction, and the step edges are used to facilitate the rubber hose 111 to deform when subjected to force. Based on this design, after the soft needle 11 is inserted, the patient's limb movement drives the soft needle 11 to be subjected to force, so that the soft needle 11 and the grabbing piece 12 can swing and move with the rubber hose 111 as the fulcrum, avoiding the retention needle in the prior art, where the soft needle 11 will penetrate deeper into the vein during limb movement, causing discomfort to the patient.

[0020] The fixing assembly 4 includes a fixing shell 41 and a rubber sheet 42. The fixing shell 41 is sleeved outside the retention tube body 3, and the rubber sheet 42 is connected to the side of the fixing shell 41. When the retention tube body 3 is fixed to the wrist through the fixing assembly 4, the rubber sheet 42 surrounds the wrist once and is connected to the fixing shell 41 to form a fixation. The upper surface of the fixing shell 41 is provided with two buckle blocks 411, and the end of the rubber sheet 42 is provided with two corresponding notches 421. The rubber sheet 42 surrounds the wrist once and is embedded in the notch 421 through the buckle blocks 411 to form a fixation. The middle to lower part of the fixing shell 41 has an elliptical outline. When the fixing assembly 4 is used, the fixing shell 41 is fixed to the wrist. When the fixed component 4 is sleeved outside the retention tube body 3, it can be positioned by the internal contour of the fixed shell 41, and a plurality of anti-slip blocks 412 are also provided at both ends of the inner side of the fixed shell 41. When fixed outside the retention tube body 3, the anti-slip blocks 412 can be used to increase the stability of the fixation to prevent the retention tube body 3 from loosening, and the retention tube body 3 can be better fixed by wrapping the rubber sheet 42 around the wrist. As shown in the figure, a plurality of anti-slip blocks 422 are equidistantly provided on the two side edges of the rubber sheet 42, and the anti-slip blocks 422 are arranged along the length direction of the rubber sheet 42. When fixed, the anti-slip blocks 422 can also form an anti-slip effect.

[0021] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
