Abstract
The utility model provides a safety type infusion apparatus which comprises a piercing device, an air filter, a safety type dropping hopper, a flow regulator, a liquid medicine filter and an infusion needle, wherein the air filter and the safety type dropping hopper are respectively connected at the lower end of the piercing device through hoses, the flow regulator is connected at the lower end of the safety type dropping hopper through a hose, and the flow regulator is sequentially connected with the liquid medicine filter and the infusion needle through hoses. The safety type infusion apparatus is characterized in that the safety type dropping hopper consists of an upper connector, an outer shell body, a safety valve and a lower connector. The safety type infusion apparatus has the advantages of simple structure, convenience in operation, low cost, good safety property and the like and has good economic benefit.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of safety type transfusion device.
Background technology
The actuator that the present transfusion device that uses clinically is provided with by an epimere tube for transfusion, Murphy's burette, hypomere tube for transfusion, venipuncture needle and tube for transfusion is from top to bottom successively formed.Though these transfusion devices are simple in structure, when transfusion finishes, can not automatic cut out, in time do not take out transfusion device and bring harm thereby cause being totally lost to patient because of liquid, increased simultaneously medical personnel workload, make operation inconvenience more.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of safety type transfusion device of simple in structure, easy to operate, low cost of manufacture is provided.
The technical scheme that this utility model adopts to achieve these goals is as follows:
A kind of safety type transfusion device, it comprises perforator, air filter, safety type dropping funnel, flow regulator, liquid medicine filter and transfusion needle, described perforator lower end connects air filter and safety type dropping funnel respectively by flexible pipe, safety type dropping funnel lower end is by hose connection flow regulator, flow regulator adopts flexible pipe to connect liquid medicine filter and transfusion needle successively, it is characterized in that described safety type dropping funnel is made up of top connection, shell body, relief valve and lower contact.
Described top connection is fixed on the shell body top and with hose connection.
Described lower contact is fixed on the shell body lowermost end and with hose connection.
Described relief valve is arranged in the shell body.
Described relief valve is the hollow most balls of a density less than water.
Described shell body top internal diameter is greater than the bottom internal diameter.
This utility model is mainly used in clinical disposable infusion, and when liquid was about to be totally lost, the energy automatic cut out was with the protection patient.On the basis of general infusion set, make common dropping funnel into the safety type dropping funnel.The safety type dropping funnel can be realized automatic cut out when liquid is about to be totally lost, in time do not take out the harm that transfusion device brings to patient to prevent to be totally lost because of liquid, also makes things convenient for medical personnel simultaneously to the medical care of a plurality of transfusion patients.Advantage such as therefore the utlity model has simple in structure, handled easily, cost is low, safety is good has favorable economic benefit.

Among the figure: 1-perforator, 2-air filter, 3-safety type dropping funnel, 3.1-top connection, 3.2 shell bodies, 3.3-relief valve, 3.4-lower contact, 4-flow regulator, 5-liquid medicine filter, 6-transfusion needle.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further,
As shown in Figure 1: the safety type transfusion device, it comprises perforator 1, air filter 2, safety type dropping funnel 3, flow regulator 4, liquid medicine filter 5 and transfusion needle 6.Described perforator 1 lower end connects air filter 2 and safety type dropping funnel 3 respectively by flexible pipe.Safety type dropping funnel 3 lower ends are by hose connection flow regulator 4, and flow regulator 4 adopts flexible pipe to connect liquid medicine filter 5 and transfusion needle 6 successively.Described safety type dropping funnel 3 is made up of top connection 3.1, shell body 3.2, relief valve 3.3 and lower contact 3.4.Described top connection 3.1 is fixed on shell body 3.2 tops and with hose connection, and described lower contact 3.4 is fixed on shell body 3.2 lowermost ends and with hose connection.
Described relief valve 3.3 is arranged in the shell body 3.2 and this relief valve 3.3 is the hollow most balls of a density less than water.
Described shell body 3.2 top internal diameters are greater than the bottom internal diameter.
Liquid splashes into earlier in the relief valve during transfusion, and after relief valve was full of, liquid just overflowed from relief valve top, enters in the shell body, because the relief valve density of material is less than water, the relief valve come-up produces a fluid passage (as shown in Figure 2).This moment, liquid passed through, but just normal infusion.When liquid is about to be totally lost, relief valve drops to the shell body foot, and fluid passage is blocked (as shown in Figure 3), realizes automatic cut out, to play protection patient's effect.Its main feature is, when liquid is about to be totally lost, still leaves liquid in the relief valve, and it is tightr that its liquid gravity can make relief valve and shell body bottom fit, and guarantees the cutout effect.
