Abstract

The utility model relates to a fixer for transfusion needle head or its connecting pipe, which is especially suitable for the fixation of the needle head position during the intravenous transfusion of the human body. The utility model is composed of a ring clamping piece, a small shaft and an elastic pressing plate, can be produced into the clamp type or the ring strip type and can be positioned in every required part of the human body to meet the requirement of the fixation of the needle head position of entering the needle from various directions. The fixer has the advantages of convenient use, fast and reliable connection, convenient sterilization, reuse, simple structure and easy fabrication. The fixer can be used for the fixation of the needle head of the animal intravenous transfusion and can also be used for the position fixation of the tracheal cannula or the humoral delivery tube.

Description

Fixator for transfusion needle or its connecting pipe

This utility model relates to medical apparatus and instruments, is a kind of human vein when transfusion of being specially adapted to, and syringe needle or its are taken over the device of fixed-site.

The syringe needle afterbody of well-known human vein transfusion usefulness is inserted with one section hard and takes over, and takes at this to connect the soft conduit of transfusion on the other end again.After syringe needle injects vein, need fix the relative human body of needle position, common way is with a rectangular arrowband adhesive plaster, with syringe needle afterbody or its adapter winding connection, remaining adhesive tape to be pasted and fixed on the skin table of human body then earlier.Adopt this fixing means to have following problem: adhesive plaster descends in cold climate viscosity, is difficult for pasting the jail; At hot climate, difficulty is pasted in the patient skin hyperhidrosis; To the uncooperative patient of child or abnormal state of mind, be difficult for reliable rapidly location and cause the syringe needle dislocation; To indivedual skin allergy patients, can not use rubberized fabric adhere; Increased the medical worker and torn the trouble of cutting adhesive plaster, and, caused waste of adhesive plaster or the like because of disposable use.

Main design objective of the present utility model is to design a kind of holder at the existing problem of above-mentioned immobilization with adhesive tape needle position, and syringe needle or its adapter can correctly be fixed on the needed by human body position rapidly.

The holder of this utility model infusion needle or its adapter, its primary structure be have can snare or be clamped in the needed by human body position, by with the localized circle folder of extruding that reclines of body skin, the little axle of multi pack on the circle folder arranged, can rely on pressure strip to connect and compress infusion needle or its adapter along the elastic compression plate of the widely different commentaries on classics of little axis with having.

Further set forth embodiment below in conjunction with accompanying drawing:

Fig. 1 is master, the vertical view signal of folder formula circle folder scheme.

Circle folder among Fig. 1 is a kind ofly to utilize elastic element 1 to open or the clip 2 of closed clamp mouth.After finishing the vein inserting needle, open the folder mouth and pierce into required limbs position (routine arm), and by the pressing body skin location that reclines after the folder mouthful closure, the vertical rivet welding of one end of little axle 3 is on a certain clamping plate plane of clip 2, the porose sky of one end of elastic compression plate 4 is enclosed within on the little axle 3, and can rotate around little axle 3 axis, so that choose compaction direction.The other end of little axle 3 is provided with screw thread, can push elastic compression plates 4 by screwing nut 8, and then infusion needle 5 afterbodys or its adapter 6 are pressed abd fixed between elastic compression plate 4 and the clamping plate plane.

Fig. 2 is the signal of circle formula circle folder scheme.

Fig. 3 is the A-A section signal of Fig. 2.

Circle folder among Fig. 2 is a kind of flexible strap 9, and its both ends respectively are provided with nylon and take piece 10, and the stickup of leaning on two nylon to take piece 10 forms the astragal of the extruding desired area body skin (routine head) that reclines.For the ease of little axle being installed and being increased the flexibility ratio of choosing the position location, mobile frame 11 of cover connection in belt 9 can be easily along belt 9 length direction slippages from the visible mobile frame 11 of Fig. 3.For making the position location press close to the skin table, little axle 3 is that vertical riveting (weldering) is on the extended surface 12 of mobile frame 11.This scheme has elastic compression plate 4 and nut 8 equally.

Fig. 4 is another Artenkreis formula circle folder scheme signal.

From the circle folder of the visible this scheme of Fig. 4 mainly by bracelet plate 14 be associated in bracelet plate 14 two ends and overlap intra-annular flexible strap 9 ' constitute.The buckle in plate 14 plane first line of a couplet are equipped with little axle 3, elastic compression plate 4 and nut 8, flexible strap 9 ' the other end respectively be provided with nylon and take piece 10.

Fig. 5 is when having wedge-like supporting plate 13, the signal of the B-B section of Fig. 1.

Because there are a small needle angle in vein inserting needle needle axis and human body skin table sometimes, in order to adapt to this needle angle, can be elastic compression plate 4 times, other establishes the similar wedge-like supporting plate 13 of a profile and pressure strip 4, the also porose sky of one end of supporting plate 13 is enclosed within on the little axle 3, can be pressed between pressure strip 4 and the supporting plate 13 thereby make syringe needle 5 afterbodys or take over 6, can keep certain needle angle simultaneously.Because the existence of supporting plate 13, can go to any direction with pressure strip 4, the vein inserting needle that is basically parallel to the fastening direction of circle folder also can be fixed, and the syringe needle of special inserting needle (the eye of a needle handle of routine scalp acupuncture etc.) also can be fixed easily.

For elastic compression plate 4 was fitted easily compressing syringe needle 5 afterbodys or compress to take over, there is concave surface 7(to see Fig. 1,2,4,5 on the pressure strip 4 at 6 o'clock).

In above-mentioned each scheme all are part in addition, and all available metal or plastics, nylon etc. are made.

Flexible strap 9,9 ' except that available nylon overlap joint piece 10 amplexiforms, also available pin-and-hole grafting, button socket, button are pressed and are connect or mode such as watchband snapping connects.

The utlity model has following good effect:

1, fixator is easy to use, connects rapidly correctly, can adapt to vein inserting needle fixing of human body all directions;

2, be convenient to sterilization, can reuse, save a large amount of medical proof fabrics;

3, simple in structure, be easy to produce by batch;

4, this holder also can be used for the fixing of animal intravenous infusion syringe.Also applicable to the fixed-site of tracheal intubation and body fluid delivery line.
