Abstract

The utility model relates to a transfusion device which can be artificially and flexibly pressed under the condition of emergency in order to quick transfusion. The utility model comprises a liquid filling bottle 3, a transfusion pipe 4 connected in series with a speed governor 6, and a transfusion needle 5, wherein an elastic saccule with a pipe inlet and a pipe outlet, which can automatically restore to the original state, is connected in series to the transfusion pipe. The pipe inlet and the pipe outlet of the saccule are both provided with one-way valves 2, and the orientations of the two one-way valves are same. Because the transfusion device capable of flexible pressurization has the advantages of simple structure and easy use. The elastic saccule only needs to be pinched by hands when the utility model is connected in series with the transfusion pipe and the pressurized transfusion is required. The pressure is generated in the saccule to accelerate the flow speed of filling liquid, and various needs of clinical therapy and transfusion can be satisfied.

Description

A kind of pressurizing infusion set flexibly

Technical field

This utility model relates to a kind of can manually when needed the pressurization flexibly so that the pressurizing infusion set flexibly of quick transfusion.

Background technology

At the clinical infusion model that is adopted when the patient infusion generally is that bottled or packed fluid infusion is hung on the frame, connects fluid infusion and transfusion needle with tube for transfusion, is connected with speed regulator in tube for transfusion, and speed regulator can only be with the mode speed governing of switch tube for transfusion.But patient need pressurize and infuse fast in many cases, especially in the process that gives emergency treatment to a patient.Existing pressure transfusion method roughly has two kinds: the one, directly push the transfusion sebific duct with hands, and the 2nd, with the prelum of overcoat packed fluid infusion is pushed.But it is imprecise that the former pushes difficult effect, and the latter can't use bottling liquid, and complex structure.

The utility model content

The purpose of this utility model just provides a kind of pressurizing infusion set flexibly simple in structure, easy to use.

For achieving the above object, pressurizing infusion set flexibly of the present utility model, comprise bottled or packed fluid infusion, be connected with the tube for transfusion and the transfusion needle of speed regulator, it is characterized in that: in tube for transfusion, also be serially connected with by one bring into, outlet spout, can restorable voluntarily resilient bladder, described sacculus all is equipped with check valve into and out of the mouth of pipe, two check valves towards identical.

Described check valve is made of the valve seat of hollow and the valve ball that is loaded on its inner chamber, has on the valve base cavity into and out of the mouth of pipe, and the entrance point of valve base cavity is a concave spherical surface, and the center has the inlet opening, and the port of export of valve base cavity be four blocks from the tube wall protrusion.

The beneficial effects of the utility model are: because pressurizing infusion set simple in structure flexibly originally, easy to use, after being serially connected in tube for transfusion, when the needs pressure transfusion, only need pinch and grab resilient bladder with hands, can make and produce pressure quickening fluid infusion flow velocity in the capsule, and when not needing to pressurize, resilient bladder can be as the part of fluid infusion passage and is not influenced the carrying out of transfusion.So more can satisfy the various needs of clinical treatment transfusion.

Description of drawings:

Fig. 1 is the cross-sectional schematic of pressurizing infusion set example structure flexibly.

Among the figure: 1 resilient bladder, 2 check valves, 3 fluid infusion bottles, 4 tube for transfusions, 5 transfusion needles, 6 speed regulators.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is described in further detail:

From Fig. 1 to Fig. 3, can see, the embodiment of pressurizing infusion set flexibly of the present utility model, comprise fluid infusion bottle 3, be connected with the tube for transfusion 4 and the transfusion needle 5 of speed regulator 6, in tube for transfusion, also be serially connected with by one bring into, outlet spout, can restorable voluntarily resilient bladder 1, sacculus into and out of the mouth of pipe all be equipped with check valve 2, two check valves towards identical.Check valve 2 is made up of the valve seat of hollow and the valve ball that is loaded on its inner chamber, have import and export on the valve seat, the inlet end face of valve base cavity is a concave spherical surface, import is opened at concave spherical surface and is hit exactly, the exit end face of valve base cavity is four blocks that protrude from tube wall, and this example is being made of one into and out of the mouth of pipe check valve and sacculus.

Using earlier gets rid of clean with reaching ducted air in the capsule, when not needing pressure transfusion, originally flexibly pressurizing infusion set as the general infusion set operate as normal, can there be speed regulator to regulate transfusion speed within the specific limits, in office what is the need for to pressurize quicken under the situation of transfusion, only need to push resilient bladder, can make the interior pressure that produces of capsule accelerate the fluid infusion flow velocity, reach and be interrupted according to actual needs or flexible constantly the pressurization to accelerate the purpose of transfusion with hands.

Claims

1, a kind of pressurizing infusion set flexibly, comprise fluid infusion bottle (3), be connected with the tube for transfusion (4) and the transfusion needle (5) of speed regulator (6), it is characterized in that: in tube for transfusion, also be serially connected with by one bring into, outlet spout, can restorable voluntarily resilient bladder (1), sacculus into and out of the mouth of pipe check valve (2) is housed all, two check valves towards identical.
