Abstract
The invention relates to a compression infusion apparatus with an anti-air plug, which can prevent the air from flowing into a patient body during the compression transfusion and pertains to the technical field of the medical apparatus and instruments. Aiming at solving a problem that the common infusion apparatus can not automatically stop after the compression transfusion is finished, the invention improves a structure of a Murphy dropper on the basis of the traditional infusion apparatus. The Murphy dropper is additionally provided with a float and a valve which are connected with each other. When the fluid in the Murphy dropper is relatively high in the height, the float can float to drive the valve to open, which results in the smooth flow of the fluid; when the infusion is dripped off, the infusion in the Murphy dropper gradually reduces and the float lowers to drive the valve to close, which results in automatic stoppage of the transfusion.
Description
Affiliated technical field
The invention belongs to medical instruments field, is a kind of pressurizing infusion set of quick transfusion.
Background technology
What at present, each hospital used in the first aid pressure transfusion substantially all is transfusion set.It is made up of the syringe needle, air inlet pipe, tube for transfusion, Murphy tube, flow-control folder, the scalp acupuncture that are inserted on the transfusion bottle stopper.The patent that has has added air bag on general infusion set, so that pressurize in infusion bottle when needing pressure transfusion.These transfusion devices have a common shortcoming, can not stop automatically after liquid is totally lost exactly.In pressure transfusion, medical personnel just might import air unless you give your whole attention to it and cause air embolism to jeopardize patient's life in the patient body.
Summary of the invention
Can not self-braking problem when solving pressure transfusion, the invention provides a kind of transfusion device, in pressure transfusion, when liquid is totally lost, can stop automatically, prevent to cause danger in the gas input patient body.
The technical solution adopted for the present invention to solve the technical problems is: transform the structure of the Murphy tube of general infusion set, add a float and a valve in Murphy tube.Float is connected with valve.In Murphy tube liquid more for a long time, float floats and drives valve and opens, liquid can circulate; When liquid is totally lost, the liquid in the Murphy tube reduces gradually, and float sinking valve cuts out, and transfusion stops automatically.
The invention has the beneficial effects as follows: when transfusion finishes, can stop transfusion by self-closing valve, prevent to cause air embolism to jeopardize patient's life in the air input patient body.
Description of drawings
Fig. 1 is the schematic diagram of first embodiment
Fig. 2 is the schematic diagram of second embodiment
Labelling among the figure: 1. Murphy tube A, 2. floating body, 3. needle, 4. sealing ring, 5. guide post, 6. Murphy tube B, 7. float, 8. hinge, 9. needle B, 10. valve seat
The specific embodiment
Embodiment 1: as shown in Figure 1, the present invention partly transforms Murphy tube to form on the basis of general infusion set.The Murphy tube part of only having drawn among the figure.Murphy tube A (1) is made by hard transparent plastic, and its underpart is shaped on coniform valve base, and valve seat interior surface is smooth.Murphy tube A is equipped with the float assembly in (1), and it is made up of floating body (2), needle (3), guide post (5) and sealing ring (4).Floating body (2) is the ducted body that is made of plastics, and proportion is lighter than water, can float in liquid.It and needle (3), guide post (5) are made one.Guide post (5) play the guiding role in needle-valve opening and closing process, and it is rhizoma sparganic or multiedge cylinder.The outer soft rubber seal (4) that is with of needle (3) is formed needle-valve jointly with coniform valve base.The more float assembly of liquid floats needle-valve is opened in the Murphy tube A (1) in infusion process, and liquid can circulate; When infusion process finished, liquid minimizing float assembly fell needle-valve is closed among the Murphy tube A (1), and transfusion stops.
Embodiment 2: as shown in Figure 2, the present invention partly transforms Murphy tube to form on the basis of general infusion set.The Murphy tube part of only having drawn among the figure.Murphy tube B (6) is made by hard transparent plastic, and its underpart is shaped on valve seat (10), and valve seat (10) inner surface is smooth.Float (7), needle B (9) etc. are housed in the Murphy tube B (6).Float (7) is the ducted body that is made of plastics, and proportion is lighter than water, can float in liquid.Have a connecting rod to be fixed on the inwall of Murphy tube B (6) by hinge (8) on the float (7), float (7) can be swung around hinge (8).Catch up with to be connected with needle B (9) in the connection of float (7), needle B (9) can catch up with swing and slides in connection.Needle B (9) is made up of multiedge cylinder and the sealing vertebral body that is fixed on the bottom.Multiedge cylinder play the guiding role in valve seat (10), and the sealing vertebral body is made to cooperate with valve seat (10) by soft rubber and seals.Needle B (9) and valve seat (10) are formed needle-valve.Liquid is more in the Murphy tube B (6) in infusion process, and float (7) floats opens needle-valve, and liquid can circulate; When infusion process finished, liquid reduced among the Murphy tube B (6), and float (7) falls needle-valve is closed, and transfusion stops.
Claims (1)
1. an anti-air embolism pressurizing infusion set is made up of the syringe needle, air inlet pipe, tube for transfusion, Murphy tube, flow-control folder, the scalp acupuncture that are inserted on the transfusion bottle stopper, it is characterized in that: a float and valve are arranged in Murphy tube.
