Abstract

The utility model relates to a fixer for a canula, and comprises a gluey pan with glue at the bottom, an elastic fixer which is horizontally arranged on the gluey pan, and a protecting buckle which can rotate and one end of which is fixed at one side of the fixer. A groove is formed at the other side of the fixer. The other end of the protecting buckle can be fastened in a groove. A horizontal and columniform fixed groove forms and runs through in the center of the fixer. An opening which connects with the fixed groove is formed at the whole length of the upper part of the fixer. The width of the opening is smaller than the diameter of the fixed groove. The fixer for a canula of the utility model can be fixed directly on the skin, and the operation is convenient. The protecting buckle can be fastened in the groove on the fixer, thereby the fixing of the canula is firmer, and the canula is not easy to fall off.

Description

Conduit retainers

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of conduit retainers.

Background technology

At present, in clinical medicine, according to circumstances usually need certain conduit, as: interposing catheter or PICC conduits such as (through the central venous catheters of periphery intubate) remaines in certain position in the body for a long time.Usually the method for the A/C that adopts is with immobilization with adhesive tape or with stitching thread conduit to be sewn on the skin.That the former the normal because change of patient's activity or posture causes fixing is not firm, conduit is deviate from; The latter can cause the tractive pain and infect, bring painful and unnecessary trouble to patient.

For this reason, people have designed various conduit retainers and have solved the problems referred to above.Figure 1 shows that the patent No. is the interventional radiology conduit retainers sketch map of ZL00267169.7.As shown in Figure 1, the prior art conduit retainers is made of a body portion 1 and the forearm 2, the postbrachium 3 that are attached thereto, is formed with between forearm and postbrachium and splits 4 between arm; Between arm, split 4 and body 1 intersection be formed with conduit trough 7; On forearm 2, be formed with clasp land place 6; Clasp 5 is installed on postbrachium 3.During use conduit is put into conduit trough 7, conduit is fixed by clasp 5 is buckled in 6 places, clasp land place.

But there is following shortcoming in the conduit retainers of above-mentioned prior art:

1. can't directly be fixed on the skin, need by other fixtures, as: adhesive tapes etc. could be fixed;

2.

clasp

5 and 6 designs of clasp land place are unreasonable, can't guarantee conduit firmly fixing; 3. axial structural design deficient in stability makes it be difficult to fix.

Summary of the invention

In order to solve above-mentioned problems of the prior art, it is a kind of easy to use and conduit firmly can be fixed on conduit retainers on the skin that the purpose of this utility model is to provide.

In order to achieve the above object; conduit retainers of the present utility model comprises: the bottom have glue lacquer disk(-sc), be horizontally set on a side and the rotary protection that elastic retainers on the lacquer disk(-sc) and an end be fixed on holder and buckle; opposite side at holder is formed with groove; the other end of protection button can snap in the groove; run through the holddown groove that is formed with horizontal cylindrical at the center of holder; be formed with the opening that is communicated with holddown groove on the whole length on holder top, the width of opening is less than the diameter of holddown groove.

The cross section of the above holder lacks shape for circle, the shape of protection button and the shape of holder adapts and its internal diameter equals the external diameter of holder.

Stretch out at two each along continuous straight runs of end of the protection button other end and to be formed with a protection button protuberance; respectively be formed with a boss at the two ends of holder 20 opposite sides; be formed with described groove on the opposite face of 2 boss, protection button protuberance snaps in the groove on the holder.

Buckle in protection and also to be formed with the protection buckle hands of being convenient to operate.

The elastic retainers of the above is made by medical grade rubber or silica gel.

Conduit retainers of the present utility model increases lacquer disk(-sc) by the bottom holder can be fixed on the skin easily, has increased the safety of using; The lacquer disk(-sc) of bottom can directly be fixed on the skin, and standing part is more firm, and flat design makes the fixing back of holder be difficult for moving, and has increased stability; In addition, conduit retainers of the present utility model can one-handed performance, and practicality is stronger, except that can fixing conduits such as tiny intervention, PICC, also can fix different conduits by conduit retainers being designed to different diameters; Because protection button snaps in the groove on the holder by protection button protuberance, so conduit is fixing more firm, the conduit difficult drop-off.

The specific embodiment

Be elaborated below in conjunction with the specific embodiment of accompanying drawing to conduit retainers of the present utility model.

As shown in Figures 2 and 3, conduit retainers of the present utility model comprises: the lacquer disk(-sc) 1 of glue is arranged at the bottom, can directly conduit retainers be fixed on the skin by lacquer disk(-sc) 1; Be horizontally disposed with flexible holder 20 on lacquer disk(-sc) 10, the cross section of holder 20 lacks shape for circle; Run through at the center of holder 20 and to be formed with the holddown groove 22 that is used to place conduit, holddown groove 22 is the cylindrical of level; On the top of holder 20, on its whole length, be formed with the opening 21 that is communicated with holddown groove 22, in order to tighten conduit, the width of opening 21 should be less than the diameter of holddown groove 22; One end of protection button 30 is fixed on a side of holder 20 and can rotates, and is formed with groove 24 at the opposite side of holder 20, and the other end of protection button 30 can snap in the groove 24.

Lacquer disk(-sc) 1 can be made by non-woven fabrics or flex foam.Holder 20 is made by elastomeric material, preferably adopts medical grade rubber or silica gel to make, and holder 20 is that cross section is the column that circle lacks shape.The shape of protection the button 30 and shape of holder 20 adapts and its internal diameter equals the external diameter of holder 20; that is: protection button 30 is that cross section is the lamellar of circular arc; in the time of in conduit is placed on holddown groove 22, protection button 30 tightly is buckled on the holder 20, plays fixation.The protection button can be by the plastic material integrated injection molding.

For protection button 30 is installed, respectively be formed with 2 boss at the two ends of holder 20 both sides, that is: form 4 boss altogether, an end of protection button 30 rotatably is fixed on 2 boss of holder 20 1 sides.On the relative face of 2 boss of holder 20 opposite sides, be formed with groove 24; stretch out at two each along continuous straight runs of end of protection button 30 other ends and to be formed with 31,2 protection buttons of protection button protuberance protuberance 31 and can to snap in 2 grooves 24 that are positioned at holder 20 opposite sides respectively.In addition, on protection button 30, also be formed with the protection buckle hands of being convenient to operate 32.

Using method to conduit retainers of the present utility model describes below.

During use; earlier lacquer disk(-sc) 1 is sticked on the corresponding site place of human body; open protection button 30; put into holddown groove 22 with inserting the good opening 21 of conduit on holder 20; since holder 20 by elastic medical grade rubber or silica gel is made and the width of opening 21 less than the diameter of holddown groove 22, so conduit can be fixed in the holddown groove 22.To protect 2 protection button protuberances 31 of button 30 movable ends to snap in respectively in 2 grooves 24 of holder 20 1 sides then, can finish the fixing of conduit.
