Description

Novel infusion set injection piece

Technical Field

The utility model relates to the technical field of medical equipment, more specifically relates to a novel transfusion system injection piece.

Background

The injection piece is used as one of the components of an infusion apparatus and a blood transfusion apparatus and is used for adding medicine in the infusion process. The fitting is widely applied to clinical transfusion and blood transfusion, and has the characteristics of large application amount and wide clinical application range. The accessory consists of an injection piece shell and a rubber plug, and when the accessory is used, medical staff injects medicine into the injection piece shell through puncturing the rubber plug by using an injector and finally injects the medicine into a patient body.

Fig. 1 and 2 are front and cross-sectional views of a prior art injection member. As shown, the prior art injection member suffers from the following disadvantages:

a. in the process of puncturing and dosing by medical staff, the risk of being injured by a needle is existed, namely, the diameter of the port of the syringe shell for accommodating the fixed rubber plug is small, the needle head is easy to slip off when the medical staff punctures carelessly, and the fingers of the medical staff are punctured;

b. the medical staff is inconvenient to hold in the process of puncturing and dosing, and puncture failure or other safety problems are easily caused;

c. the liquid inlet pipe is a straight pipe and is obliquely connected with the injector shell, and the distance between the connecting point and the end cap is larger, so that the dosing dead angle of the injection piece is larger, bubbles are easy to generate, and air is injected into the patient body.

There is therefore a need to develop a new infusion set injection device that at least partially solves the problems of the prior art.

SUMMERY OF THE UTILITY MODEL

To this end, the present application aims to provide a novel infusion set injection piece, including: the injection piece comprises an injection piece shell (10), a liquid inlet pipe (20), an end cap (30), a rubber plug (40) and a supporting rib (50);

wherein, the end cap (30) is positioned at the upper end of the injection piece shell (10) and is used for accommodating a fixing rubber plug (40);

the liquid inlet pipe (20) is connected with the injection piece shell (10), and the connection point is close to the end cap (30); the liquid inlet pipe (20) is a bent pipe, and a section close to the connection point is arc-shaped;

support ribs (50) are provided on the outer periphery of the injection piece housing (10) and connect the lower surface of the end cap (30).

According to an embodiment of the invention, the support ribs (50) are two and are arranged at an interval on the periphery of the injection piece housing (10).

According to the utility model discloses an embodiment, novel transfusion system injection still includes end cap lid (60), is used for fixed rubber buffer (40).

According to an embodiment of the invention, the side wall thickness of the end cap (30) is greater than the bottom surface thickness.

The novel infusion set injection piece of the utility model is safer in design, and can prevent medical personnel from being injured by acupuncture; the design is easier to hold, and the operation is more convenient and safer; in addition, dead angles of the design are smaller, air is not easy to gather to generate bubbles, and the infusion safety of a patient is ensured.

Detailed Description

The invention can be better understood with reference to the following examples and the accompanying drawings. However, those skilled in the art will readily appreciate that the description of the embodiments is only for the purpose of illustration and should not be taken as a limitation of the invention.

Fig. 3 is a schematic perspective view of an infusion set injection member according to an embodiment of the present invention; FIG. 4 is a schematic perspective view of another angle; and fig. 5 is a schematic cross-sectional view of the infusion set injection part; referring to fig. 3-5, the infusion set syringe may include a syringe housing 10, an inlet tube 20, an end cap 30, a rubber stopper 40, support ribs 50, and an end cap cover 60.

The injection piece housing 10 is cylindrical; an end cap 30 is provided at the top end of the cylinder and communicates with the injection piece housing 10, and a rubber stopper 40 is accommodated in the end cap; thus, the end cap is substantially shaped to conform to the rubber stopper 40; an end cap 60 is disposed over the end cap 30 for covering the rubber stopper 40; the end cap 60 has a through hole formed in the center of the top surface thereof, and a rubber stopper is exposed, whereby a needle can be administered by piercing the rubber stopper into the injection housing 10.

As shown, the end cap of this embodiment may be sized larger than the prior art, for example the diameter of the end cap 30 is larger than the diameter of the injection piece housing 10; in addition, the side wall of the end cap 30 is formed thicker than the bottom surface thereof, thereby facilitating the connection (welding) with the end cap 60; like this, when medical personnel added medicine, the margin is bigger, thereby can prevent that medical personnel from puncturing carelessly and pricking medical personnel's finger with the needle slippage.

The inlet pipe 20 is connected to and communicates with the injection housing 10, and may be integrally formed, for example. As shown, the inlet pipe 20 is an elbow pipe, and a section near the connection point is arc-shaped, so that the connection point of the inlet pipe 20 and the injection member housing 10 can be close to the end cap 30, thereby reducing the dead angle of the injection member, reducing the generation of bubbles, and not preventing the larger diameter end cap 30.

In addition, a support rib 50 is provided on the outer circumference of the injection piece housing 10 and connects the lower surface of the end cap 30. As shown, two support ribs 50 are provided in this embodiment, and are spaced apart from the inlet pipe 20. Compared with the prior art, the injection piece shell is additionally provided with the supporting ribs, so that the injection piece shell can be conveniently held by medical personnel, and meanwhile, the risk of stabbing injury is further reduced. Of course, other numbers of support ribs may be provided as desired.

In the embodiment of the utility model, the sizes of the rubber plug end cap and the end cap cover of the injection piece are increased, that is, the plane area of the end cap is large enough, so that the puncture needle can shield fingers when slipping, thereby playing a role of protection; the injection piece shell is added with two supporting rib characteristics so as to achieve the purposes of facilitating the holding of medical personnel and further reducing the risk of puncture injury; in addition, dead angles of the injection piece are reduced by changing the structure, and the aim of reducing bubbles can be fulfilled.

The specific embodiments are given above, but the present invention is not limited to the above-described embodiments. The basic idea of the utility model lies in the above basic scheme, to the ordinary technical personnel in this field, according to the utility model discloses a teaching, design model, formula, the parameter of various deformations and do not need the creative work of cost. Variations, modifications, substitutions and alterations of the embodiments may be made without departing from the principles and spirit of the invention, which is to be understood as falling within the scope of the invention.
