Abstract

The utility model provides a disposable medicine adding device which relates to a medicine adding device used in infusion dispensing, belonging to a medical appliance. The disposable medicine adding device comprises a liquid passing tube and a long air passage. The liquid passage comprises an inner chamber of a long needle tube (1), a liquid passing tube (5) in the base of the long needle tube, a liquid passing leather tube (15), a liquid passing tube (14) in the base of a short needle tube, a short needle tube (11), and an inner chamber which are tightly connected together. The long air passage comprises a long needle tube sleeve hole (2), a long needle tube external gap (3), an air passing tube in the base of the long needle tube (4), an air passing leather tube (6), and a long air passing base port (7) in the base of the short needle tube which are tightly connected together. The air flowing in and out of the tubes is controlled in order to solve the problem that a traditional medicine adding device can not effective dispense. The utility model has the advantages of less pollution, less medicine waste and convenient operation; the disposable medicine adding device can be used in the field of clinical medicine.

Description

Disposable use drug feeding device

Affiliated technical field this utility model relates to a kind of chemicals dosing plant, belongs to medical medical apparatus and instruments.

Background technology for a long time, the drug feeding device of Shi Yonging is made up of syringe needle, syringe clinically, the medical worker arrests syringe with hands during use, needle point is inserted in the liquid medicine bottle of breakdown and take out medicine, when running into medicine powder, also need aerating in airtight infusion bottle, drawing liquid, like this, the syringe needle syringe usually needs repeatedly dealing to use.Medical worker's hands contacts nook closing member easily, easily brings filth into, pollutes medicinal liquid, and when taking out medicine, resistance is big, inconvenient operation, and medicinal liquid is also easily residual, outer to drip.

The summary of the invention the purpose of this utility model just provides that a kind of pollution is few, and drug waste is few, easy to operate disposable use drug feeding device.

Technical scheme this utility model is made of side by side fluid-through tube road and long airway two parts, the fluid-through tube road is interconnected and is formed by fluid-through tube road, hour hand pipe interior conduit in fluid-through tube road, logical liquid leather strap, the hour hand base in minute hand pipe interior conduit, the minute hand base, and long airway is interconnected by the long ventilation seat mouth on the breather line in needle tubing trepanning, minute hand pipe external series gap, the minute hand base, ventilation leather hose, the hour hand base and forms.During use, with long airway the gas in the infusion bottle is extracted out, medicinal liquid can enter in the infusion bottle by the fluid-through tube road.Fluid-through tube road tube wall is smooth airtight, and when medicinal liquid passed through, less wastage polluted and lacks, and its operation can electrified be controlled, and is easy to operate.

Beneficial effect is compared with traditional drug feeding device, and it replaces original loosely organized syringe needle syringe with fluid-through tube road, breather line, makes it and can electrified operate, and pollutes and lacks, and liquid waste is few, and is easy to operate.

Description of drawings Fig. 1: the structure chart of product

Among the figure: 1, fluid-through tube road 6 in breather line 5, the minute hand base in the minute hand pipe 2, minute hand canister aperture 3, minute hand pipe external series gap 4, minute hand base, the ventilation skin official 7. long ventilation seats mouthfuls 8. fluid-through tube road 15. logical liquid leather hoses in the breather line 14. hour hand bases that block water in 9. groups of moisture films of film, 10. hour hand canister apertures, 11. hour hand pipes, 12. hour hand pipe external series gaps, the 13. hour hand bases

Specific embodiment this utility model by the minute hand pipe 1., minute hand base, logical liquid leather hose , ventilation leather hose 6., hour hand base, hour hand pipe form.The 1. stainless steel of minute hand pipe, front end has a side opening, can thrust rubber stopper easily, do not produce exfoliation, its length needle point when thrusting infusion bottle can enter bottle below the interior liquid level, and its end is inserted in the minute hand base, and the fluid-through tube road in the elongated needle tubing seat of inner chamber 5., minute hand base plastics system, one end is the minute hand pipe box, on the minute hand canister aperture is arranged 2., the other end has two outstanding to connect logical liquid leather strap and ventilation leather hose respectively 6., annular minute hand pipe external series gap is arranged 3. between minute hand pipe box and the minute hand pipe, minute hand pipe external series gap 3. encircle be trapped among the minute hand pipe 1. outside, the space is little, opening be the minute hand canister aperture 2., in in the elongated needle tubing seat breather line 4., and gas skin tube is 6. all again.5. outstanding connection of fluid-through tube road in the minute hand base led to liquid leather hose .The ventilation leather hose 6., the other end of logical liquid leather hose is connected on the hour hand base, the ventilation leather hose is 6. by the long 7. pass-out of seat mouth of ventilating on the hour hand base, 7. long ventilation seat mouth gives prominence to the side at the hour hand base, the gas tube orifice of shape and air pump is supporting, air pump is realized electrified operation by this mouth, by hour hand pipe inner chamber pass-out, the structure of hour hand pipe with the minute hand pipe 1., and is but shorter by the fluid-through tube road in the hour hand base for logical liquid leather hose , there is an annular gap hour hand pipe outside, structure with minute hand pipe external series gap 3., its opening be the hour hand canister aperture 10., breather line in the interior logical hour hand base, 9. short ventilation blocks water film in the road junction, can allow gas pass through, stop liquid to pass through, and can filter the foreign bodies such as antibacterial in the gas that passes through, 8. long ventilation seat mouth also blocks water film in 7., and structure is with blocking water film 9. in the short blow vent.

10. short blow vent, breather line , hour hand pipe external series gap in the hour hand base closely are connected mutually with the hour hand canister aperture, form short airway.

Long ventilation seat on the hour hand base mouthful 7., the ventilation leather hose 6., the breather line in the minute hand base 4., the outer gap of minute hand pipe 3., 2. the minute hand canister aperture closely connect, and forms long airway.

1. the fluid-through tube road 5. in the inner chamber, minute hand base, fluid-through tube road , hour hand pipe inner chamber closely connect to form the fluid-through tube road in the logical liquid leather hose , hour hand base for the minute hand pipe.
