Description

Joint fixing structure

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a joint fixing structure.

Background

The Chinese patent with the prior art publication number of CN102641529B discloses an indwelling needle, which comprises a needle head assembly, a liquid injection joint assembly, wherein the needle head assembly and the liquid injection joint assembly are connected through a catheter, the needle head assembly comprises a cannula seat and a puncture needle, the front end of the cannula seat is provided with an indwelling hose, a separation plug is arranged in the cannula seat, the cannula seat is separated into a liquid injection cavity and a needle seat cavity through the separation plug, the puncture needle comprises a needle head and a needle handle, and a handheld part is arranged on the needle handle, and the indwelling needle is characterized in that: the outer wall of the needle seat cavity is sleeved with a steel needle protecting sleeve, the steel needle protecting sleeve is of a drawing type structure formed by 3-4 sections of sleeves, the rear end of a first section of sleeve is provided with a needle handle retainer ring, a buckle is arranged between the last section of sleeve and the outer wall of the needle seat cavity, a drawing locking mechanism is arranged between adjacent sleeves, the rear end of each section of sleeve is provided with a notch corresponding to the position of the hand-held part of the needle handle, the drawing locking mechanism comprises a clamping groove arranged at the end part of one section of sleeve, and an elastic clamp matched with the clamping groove is arranged at the end part of the corresponding other section of sleeve.

After the indwelling needle is clinically used, the infusion connector component, namely the Y-shaped connector, is required to be fixed, and the fixing mode adopted by the current medical staff is as follows: and a bifurcation of the liquid injection joint assembly is stuck and fixed on the arm by using a medical adhesive tape. This type of fixation has the following problems: the liquid injection joint component is Y-shaped in structure, the width of the medical adhesive tape is limited, the medical adhesive tape needs to be fixed in a plurality of sections, the stability of the medical adhesive tape can be guaranteed, but after the medical adhesive tape is adopted for fixing, the head of the liquid injection joint component is exposed, and when the medical adhesive tape is worn, taken off or moved, the head of the liquid injection joint component is easily hung, so that the medical adhesive tape is fixed for degumming, and certain potential safety hazards can exist. The medical adhesive tape or the medical bandage with wide width is adopted for winding and wrapping, although the risk of mistakenly touching and hanging the infusion connector assembly can be solved, the medical adhesive tape or the medical bandage with wide width is required to be detached when the head of the infusion connector assembly is completely wrapped for infusion, the infusion needle is inserted and then is fixed by the medical adhesive tape, and the infusion connector assembly is complicated and inconvenient.

Disclosure of Invention

(1) The self-adhesive dressing body can be used for effectively wrapping the liquid injection joint assembly, so that the error collision is reduced, the reinforcing adhesive tape is torn off when the infusion is needed, the liquid injection joint assembly is pulled out, the self-adhesive dressing body does not need to be torn off, the liquid injection joint assembly is inserted into a notch after the infusion is completed, the number of the torn self-adhesive dressings is reduced, the working efficiency is improved, and the error collision probability is also reduced.

(2) The incision is "one" style of calligraphy, and the surface of self-adhesion dressing body is located notched top, and is located the position of annotating liquid joint component bifurcation head and offered the puncture hole, and when the puncture hole of seting up is for convenient infusion, need not follow the internal extraction of self-adhesion dressing with annotating liquid joint component, saves the operation, and is more convenient.

(3) The notch is inverted T-shaped, the structural mode can be conveniently fixed, the notch can be well wrapped, false touch is reduced, and the structure is simpler.
