Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing technology, and in particular relates to an indwelling needle fixation device. Background Technology

[0002] Currently, clinical fixation of indwelling needles mainly relies on elastic bandages or adhesive tape, which has the following drawbacks: elastic bandages or adhesive tape can only fix the indwelling needle, but cannot protect it. If the indwelling needle comes into contact with a foreign object, it is prone to displacement. Furthermore, when patients repeatedly and excessively bend their wrists, the tension in the skin and subcutaneous tissue directly pulls on the dressing and catheter used to fix the indwelling needle, causing the needle tip to shift within the blood vessel or dislodge. To address these shortcomings, we propose an indwelling needle fixation device. Utility Model Content

[0003] The purpose of this invention is to provide an indwelling needle fixation device to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: A device for fixing an indwelling needle, comprising: A hand guard, the hand guard comprising a base plate and three elastic fabric finger sleeves fixed to the upper surface of the base plate; The needle protection structure includes a protective cover with two sliders symmetrically fixed to its lower end, a groove on the upper surface of the substrate, an infusion tube groove on the right side wall of the protective cover, a limiting component on the outer surface of the protective cover, and a spring fixing mechanism inside the sliders, wherein the groove and the sliders slide in cooperation. The limiting component includes a hook and loop side of hook and loop that cooperate with each other; The spring fixing mechanism includes a mounting groove on the surface of the slider, a fixing pin that slides in cooperation with the mounting groove, a compression spring disposed on the inner wall of the mounting groove, and a plurality of through-shaped fixing holes evenly arranged on the inner wall of the groove, wherein the fixing holes allow the fixing pin to pass through.

[0021] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an indwelling needle fixation device.

[0022] like Figure 1-7 As shown, the present invention provides an indwelling needle fixing device, comprising: a hand guard, a needle protection structure, and a wrist support structure.

[0023] The hand guard consists of a base plate 10 and three elastic fabric finger sleeves 11 fixed to the upper surface of the base plate 10. The base plate 10 and the three elastic fabric finger sleeves 11 fix the patient's fingers and prevent excessive hand movement during infusion.

[0024] The needle protection structure includes a protective cover 20, with two sliders 21 symmetrically fixed to its lower end, a groove 22 formed on the upper surface of the substrate 10, an infusion tube groove 23 formed on the right side wall of the protective cover 20, a limiting component on the outer surface of the protective cover 20, and a spring fixing mechanism inside the sliders 21. The protective cover 20 is made of transparent acrylic material, and the groove 22 slides with the sliders 21. The groove width of the infusion tube groove 23 is 0.2-0.3 cm smaller than the outer diameter of the indwelling needle Y-type connector.

[0025] The spring fixing mechanism includes a mounting groove formed on the surface of the slider 21, a fixing pin 40 that slides in the mounting groove, a compression spring 41 disposed on the inner wall of the mounting groove, and a plurality of through-holes 42 equidistantly arranged on the inner wall of the slide groove 22, wherein the fixing holes 42 allow the fixing pin 40 to pass through, one end of the compression spring 41 abuts against the inner wall of the mounting groove, and the other end of the compression spring 41 abuts against one end of the fixing pin 40.

[0026] The protective cover 20 moves laterally through the sliding cooperation between the slider 21 and the slide groove 22, so that the protective cover 20 can be moved to the indwelling needle puncture position according to the size of the patient's palm, and the indwelling needle at the puncture position is protected to avoid contact with external objects. The compression spring 41 in the spring fixing mechanism pushes the fixing pin 40 to insert into the fixing hole 42 on the inner wall of the slide groove 22 to achieve multi-position locking.

[0027] The limiting component includes a hook and loop fastener 30 and a rough hook and loop fastener 31 that cooperate with each other. The adhesion of the hook and loop fastener 30 and the rough hook and loop fastener 31 can quickly adjust the opening and closing of the infusion tube slot 23, which facilitates the entry and exit of the infusion tube. When the infusion tube enters the infusion tube slot 23, the Y-type connector is inside the protective cover 20. Then, the hook and loop fastener 30 and the rough hook and loop fastener 31 are glued together to close the infusion tube slot 23. The infusion tube slot 23 is narrower than the Y-type connector, which can limit the Y-type connector. When the infusion tube is pulled, the Y-type connector cannot slide out of the infusion tube slot 23, thereby preventing the indwelling needle from shifting due to the pulling of the infusion tube.

[0028] A wrist support structure is positioned above the base plate 10 to support the patient's wrist. The wrist support structure includes a ramp pad 50, symmetrically arranged insertion grooves 51 on the upper surface of the base plate 10, hypoallergenic adhesive tape 52 passing through the inner wall of the insertion grooves 51, and an adjustment component positioned below the ramp pad 50. The ramp pad 50 is made of memory foam, and there are two hypoallergenic adhesive tapes 52. The ramp pad 50 adapts to the physiological curvature of the wrist by tilting its surface. The two hypoallergenic adhesive tapes 52 pass through the insertion grooves 51 and cross around the wrist for fixation, achieving flexible restraint and thus preventing excessive bending of the wrist.

[0029] The adjustment assembly includes a locking bolt 60 fixedly installed on the lower surface of the ramp pad 50, an elongated adjustment groove 61 formed on the upper surface of the base plate 10, and a nut 62 threaded onto the surface of the locking bolt 60. The bottom of the base plate 10 is provided with a relief groove 63 communicating with the adjustment groove 61, the depth of which is greater than the height of the nut 62. Both the nut 62 and the locking bolt 60 are made of medical plastic. The locking bolt 60 slides along the elongated adjustment groove 61, thereby adjusting the position of the ramp pad 50 according to the position of the patient's wrist. The relief groove 63 provides rotation space for the nut 62. After tightening the nut 62, the ramp pad 50 can be fixed on the base plate 10.
