Abstract

A safe type doser comprises a dosing main body, wherein the dosing main body is provided with three openings, and the three openings are respectively connected with a first needle head, a pressure device and a rubber pipe. A second needle head is connected with the other end of the rubber pipe, a rubber sleeve which is shorter than the first needle head is sleeved on the first needle head, and a rubber sleeve which is shorter than the second needle head is sleeved on the second needle head. The safe type doser is simple in structure and convenient to operate. According to the safe type doser, a traditional open type dosing process is changed into a closed type process, sterile operation is guaranteed, and the pollution probability of agent liquid is reduced. The first needle head is sleeved with the rubber sleeve which is shorter than the first needle head, and the second needle head is sleeved with the rubber sleeve which is shorter than the second needle head. When the first needle head and the second needle head are inserted in a bottle body, rubber sleeves can be jacked up smoothly, the needle heads can be inserted smoothly. When the first needle head and the second needle head are pulled out, the rubber sleeves rebound automatically. Agent liquid waste and air pollution caused by outward splashing of the agent liquid are prevented, hurt caused by inhaling of a harmful agent is avoided, the pricking wound probability for a nurse is reduced, and medication safety of a patient is effectively guaranteed.

Description

A kind of safety drug feeding device

Technical field

This utility model relates to medical instruments field, relates to specifically a kind of safety drug feeding device.

Background technology

Existing disposable transfusion device does not generally have chemicals dosing plant, during clinical transfusion, when the patient who needs the intravenous injection antibiotic etc is carried out infusion treatment, medical personnel need first with syringe powdered drug dilution in the medicine bottle, and then the medicinal liquid after will diluting is injected in the transfusion device, and this adding method thereof medical worker's labor intensity is large, complex operation, the nurse stabs oneself easily, and easily splash in the process of dosing, causes liquid waste and easy contaminated air.

The utility model content

The deficiency of this utility model in order to solve the problems of the technologies described above, a kind of safety drug feeding device is provided, it is simple in structure, with low cost, and easy to operate, this utility model becomes traditional open dosing flow process into a closed flow process, can guarantee the sterile working, reduce the pollution probability of medicinal liquid, medicinal liquid spatters liquid waste and the air pollution that causes outward when preventing from making up a prescription, and avoids harmful medicine imbedibility injury, reduce the probability of nurse's needle injuries, more effectively guarantee patient's drug safety, the personal safety in the time of can guaranteeing nurse's dosing has reduced again nurse's labor intensity.

The deficiency of this utility model in order to solve the problems of the technologies described above, the technical scheme that adopts is: a kind of safety drug feeding device, comprise the dosing main body, described dosing main body is provided with three ports, three ports are connected with respectively syringe needle I, pressue device and sebific duct, the described sebific duct other end is connected with the syringe needle II, and cover has the gum cover less than syringe needle I length on the syringe needle I, and cover has the gum cover less than syringe needle II length on the syringe needle II.

This utility model also is provided with support end on the described dosing main body.

The beneficial effects of the utility model: this utility model is simple in structure, with low cost, and easy to operate, this utility model becomes traditional open dosing flow process into a closed flow process, can guarantee the sterile working, reduce the pollution probability of medicinal liquid, on syringe needle I and the syringe needle II all cover have than the little gum cover of needle length separately, when syringe needle I and syringe needle II insert bottle constantly gum cover smoothly jack-up syringe needle is inserted smoothly, when syringe needle I and syringe needle II are extracted, the gum cover automatic rebounding, medicinal liquid spatters liquid waste and the air pollution that causes outward when preventing from making up a prescription, avoid harmful medicine imbedibility injury, reduce the probability of nurse's needle injuries, more effectively guarantee patient's drug safety, personal safety when guaranteeing nurse's dosing, position corresponding with pressue device in this utility model also is provided with support end, and when the nurse carried out dosing and need to pressurize, a finger was pressed pressue device, one finger supported end, can either effectively pressurize, can save muscle power again, make operation become convenient, comfortable.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Labelling among the figure: 1, dosing main body, 2, the syringe needle I, 3, pressue device, 4, sebific duct, 5, the syringe needle II, 6, gum cover, 7, support end.

The specific embodiment

As shown in the figure, a kind of safety drug feeding device, comprise dosing main body 1, described dosing main body 1 is provided with three ports, three ports are connected with respectively syringe needle I 2, pressue device 3 and sebific duct 4, and described sebific duct 4 other ends are connected with syringe needle II 5, and cover has the gum cover 6 less than syringe needle I 2 length on the syringe needle I 2, cover has the gum cover 6 less than syringe needle II 5 length on the syringe needle II 5, also is provided with support end 7 on the described dosing main body 1.

When inserting syringe needle II 5 in the dispensing bottle when this utility model uses, Jiao Gai on the syringe needle II 5 on the gum cover 6 contact dispensing bottles of cover can automatic jack-up enter syringe needle II 5 smoothly, the extruding pressue device, can make the medicinal liquid in the dispensing bottle enter smoothly sebific duct and then enter syringe needle I 2 by syringe needle II 5, syringe needle I 2 connects infusion bottle, can make medicinal liquid enter smoothly infusion bottle, after adding enough medicinal liquids, gum cover 6 meeting automatic reboundings protect syringe needle II 5 and prevent that medicinal liquid from splashing when extracting syringe needle II 5, cause liquid medicine contamination, after same transfusion is finished, gum cover 6 meeting automatic reboundings protect syringe needle I 2 and prevent that medicinal liquid from splashing when extracting syringe needle I 2, cause liquid medicine contamination, and position corresponding with pressue device in this utility model also is provided with support end, when the nurse carries out dosing and need to pressurize, one finger is pressed pressue device, and a finger supported end can either effectively pressurize, can save muscle power again, make operation become convenient, comfortable.

This utility model is simple in structure, with low cost, and easy to operate, this utility model becomes traditional open dosing flow process into a closed flow process, can guarantee the sterile working, reduce the pollution probability of medicinal liquid, on the syringe needle II there be than a little little gum cover of syringe needle II length cover, when the syringe needle II is drawn medicinal liquid gum cover smoothly jack-up make the syringe needle II draw smoothly medicinal liquid, when the syringe needle II is extracted, the gum cover automatic rebounding, medicinal liquid spatters liquid waste and the air pollution that causes outward when preventing from making up a prescription, and avoids harmful medicine imbedibility injury, reduce the probability of nurse's needle injuries, more effectively guarantee patient's drug safety, the personal safety when guaranteeing nurse's dosing reduces again nurse's labor intensity simultaneously.
