Abstract

An intravenous catheter assembly with flexible extender and protector against needle tip comprising an intravenous catheter (2) together with a flexible extender (7) for infusions, passing over an introducing needle (1), which extender (7) may prevent the undesirable escape of blood or other infusions with a simple strangulation. It is essentially composed of a rigid or semi-flexible concave handle (16) which shelters the needle (1) and the other components, including the flexible extender (7); by using the handle-casing, the catheter packaging is discarded, requiring only a lid (17) which combined with the handle (16), hermetically closes the catheter (2). A protector for the needle tip is also provided for effecting greater safety and hygiene.

Description

The venous transfusion pipe that has flexible and extendable and needle tip protector

The goods of by name " the venous transfusion pipe that has flexible and extendable and needle tip protector " are characterised in that; it has a little flexible pipe that is used to infuse; it can prevent from simply to grip to press causes blood to flow out, and this situation before tube for transfusion or its lid connect only a hands with oneself promptly can cause.Therefore, its process of linking on the patient body becomes easily, needn't worry that blood flow comes out, and it is better than utility model and " singly goes out the portal canal apparatus ", this apparatus because of the hole on its latex body (flexible hand cover curve) cause hemorrhage, the situation that it causes because of a variety of causes as traditional tube for transfusion.In addition, the protector of a protection needle point is arranged thereon, be positioned at the pin end, be used for connecting the back it and needle point are separated at tube for transfusion.

Be that accompanying drawing is described and each component representation below:

Fig. 1 represents the use location of " having the venous transfusion pipe of flexible and extendable and needle tip protector ";

Fig. 2 represents the moment after tube for transfusion inserts vein, wherein shows with hands and grips flexible and extendable of pressure, also shows the action of the protector of protection needle point.

Fig. 3 represents separating of tube for transfusion and opening: protector is connected on the tube for transfusion, opens up to the safety cable full extension, prevents that protector and other parts of apparatus from separating, and places it in operating position;

Half flexible grip during Fig. 4 represents to use;

Fig. 5 represents that this apparatus is arranged in the shell of a column, little, sealing, protection needle point, tube for transfusion and flexible and extendable.At last, bracing frame is occupied by each parts, finishes the layout of each parts;

Fig. 6 represents the use location of this apparatus;

Fig. 7 illustrates separated portions of the present invention;

Fig. 8 represents the operation of this apparatus, and the be fixed bracing frame of back band pin of tube for transfusion is shown.

Each parts among the figure:

1-guid needle, its length can pass whole flexible and extendable length, arrive the other end, the transfusion tip.Thin pin can separately form seam, so that observe blood flow.

2-venous transfusion pipe box.

The 3-blood vessel.

4-rigidity (or flexible) transfusion pipe box substrate, it is connected in transfusion flexible pipe 7, the outer housing that it has an inner cone and centers on it.

Projection in this apparatus indent handle of 5-, pipe box opening 4 is used to infuse.

The 6-counterpart, it must be connected in apparatus body projection 5, and is stable in the fashionable assurance of thorn.

The 7-flexible pipe of infusing is connected in transfusion pipe box substrate 4.

The opening of 8-transfusion flexible pipe, guid needle are by it, and it cooperates with the protection pawl.

9-pin protection pawl comprises: two bending pressure plates, and direction is with respect to pin, so that isolate its point; And two bending flanges, the wall of the extension opening 8 of infusing relatively.When 13 extensions of stop rope, protector separates with the opening of transfusion extension, and it is in the position on the needle point automatically, and this needle point is not connected with tube for transfusion this moment.

10-rigidity contact area 11 or flexible contact area 14.

11-tube for transfusion keeper is a recessed handle, and it is by surrounding the protection pin, and the interior section that extension and needle tip protector, all these parts pass through it connects.

12-is positioned at the pin substrate of tube for transfusion keeper 11 inside, and its bottom has a filter.

13-stop rope, it is a fine rule, has certain intensity and length, breaks away from so that prevent protector 9.

14-half flexible, concave handle, it pushes down flexible connecting member 4, when when being needled into blood vessel, providing bigger susceptiveness and stability with thin.

Crack in the 15-pin is so that confirm blood flow.

16-column handle, it protects its inner remaining part.

17-seals the lid of this apparatus.

18-tube for transfusion guid needle substrate is fixed on the bottom.

The 19-bracing frame has half flexible lateral, and it has hole 20 and the chamber 22 that the restriction bracing frame moves.

Described hole of 20-and case protrusion 21 cooperate.

The internal projection of 21-handle (housing) 16.

22-bracing frame chamber is intended to and described protruding 21 is cooperated, and limits it and move in that handle-shell is intravital.

Claims

1. venous transfusion pipe that has flexible and extendable and needle tip protector; it is characterized in that it has a transfusion flexible and extendable (7) and transfusion pipe box substrate (4), three kinds of dissimilar handles (11; 14 and 16), and the columnar stays frame (19) of puncture back protection needle point.

2. the venous transfusion pipe that has flexible and extendable and needle tip protector as claimed in claim 1 is characterized in that it has an indent handle (11), and it is around flexible and extendable (7); And a fixed lobe (5), the indenture in transfusion pipe box substrate (4) cooperates, as Fig. 1, shown in 2 and 3.

3. the venous transfusion pipe that has flexible and extendable and needle tip protector as claimed in claim 1 or 2; it is characterized in that; it has half flexible grip (14) of an indent; the pin that its protection one is thin; this pin has a hole in the middle; so that when arriving blood vessel, indicate, when being installed, tube for transfusion provides susceptiveness (Fig. 4) preferably.

4. as the described venous transfusion pipe that has flexible and extendable and needle tip protector of claim 1,2 or 3, it is characterized in that it has a column handle (16), this handle is protected within it portion (18) (pin depart from be shown in Fig. 5,6,7 and 8) with guid needle (2); And having bracing frame (19), it departs from the protection needle point.
