Description

Alarm infusion apparatus dams
Technical field
This utility model relates to technical field of medical instruments, especially a kind of medium is imported the intravital apparatus of people in the mode of intravenous drip.
Background technology
Transfusion device is in infusion process, when liquid output finished if meet accident or in the bottle, especially when negative pressure venous transfusions such as jugular vein finished, patient, medical personnel did not in time find or handle, just might cause the air admission human body in the apparatus, bring danger to patient.In order to address this problem, people have designed the various air that prevent and entered the transfusion device of human body in infusion process.As " medical automatically drip-stopping alarm infusion apparatus " (Chinese patent application number be 88210273), this technical scheme is the bottle of a splendid attire medicinal liquid, the float that the metal catch and the control warning circuit conducting of guide alarm circuit is housed on it and stops dripping, when medicinal liquid will drip off, send alarm signal and also stop automatically.This transfusion device still exists not enough in use: the one, and it need increase a warning infusion bottle, and cost is higher, as waste of disposable use; The 2nd, as reusing product, in use, not only need general infusion set, but also need the other adapted should the warning infusion bottle, after use, need to clean, autoclave sterilization the use cost height; The 3rd, when patient need import many bottles of liquid, all need liquid is injected the warning infusion bottle earlier, not only use inconvenience, and increased the pollution risk of transfusion.
Summary of the invention
Subject matter to be solved in the utility model provides a kind of manufacturing cost, use cost is low, and can in time close the alarm infusion apparatus that dams of infusion channel and connection nurse help system circuit when transfusion finishes.
In order to address the above problem, the scheme that this utility model adopts is: it includes the tube for transfusion and the Murphy type burette of structure same as the prior art, and described tube for transfusion is communicated with the capsule bag, and this capsule bag outer surface is connected with a pair of circuit contact.Described capsule bag is meant that a kind of outer wall has elasticity, the container that can swell or dwindle when the difference of pressure medium and its outer air pressure changes within it, generally can make by rubber, plastics, described a pair of circuit contact be meant two in correspondence with each other, separable or contact, the electric conductor that is connected to lead on it.
The passage that above-mentioned capsule bag inner chamber is communicated with described tube for transfusion can be provided with upper channel and be positioned at the lower channel of this upper channel below, described a pair of circuit contact can be connected on the capsule bag outer surface by contact board, its structure is that a pair of circuit contact is contained in respectively on the end of two contact board, the other end of these two contact board sticks in described capsule bag outer surface, and the middle part of described two contact board connects by hinge.Above-mentioned capsule bag preferably is located at described Murphy type burette between the tube for transfusion inlet, be provided with one in the described Murphy type burette by float be connected the valve plug that the valve rod of the taper that this float below, lower end be constitutes, when the liquid level of Murphy type burette descended above desired location, this valve plug lower end can be blocked on the liquid outlet of Murphy type burette.Described valve rod is outer can be provided with the bracing ring that is contained in described Murphy type burette inwall, can be provided with limited object on the valve rod under this bracing ring, opens excessive with the restriction valve plug.Above-mentioned a pair of circuit contact can be connected with plug by lead, can conveniently send alarm signal to alarm device by this plug.
Owing to adopted such scheme this utility model compared with prior art to have following beneficial effect:
1, owing to is communicated with the capsule bag at tube for transfusion, this capsule bag outer surface is connected with a pair of circuit contact, and in Murphy type burette, be provided with valve plug, therefore, this transfusion device has the warning function of damming, and when liquid is totally lost, not only in time reports to the police, keep certain medicinal liquid in the Murphy type burette but also can make, allow and leave time enough after reporting to the police and make things convenient for the nurse to change medicinal liquid to continue transfusion or in time come to finish transfusion.
2, because cost is low, can be used as disposable product, therefore, do not need in the use to clean, sterilize, reduce use cost, reduce pollution risk.
3, this transfusion device has the advantage that volume is little, cost is low, and its manufacturing cost only is 1/3~1/4 of an above-mentioned prior art.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is an A-A place cutaway view among Fig. 1.
Among the figure: 1. needle for inserting bottle, 2. upper tubing, 3. tube for transfusion joint, 4. connection tube, 5. upper channel, 6. capsule bag, 7. lower channel, 8. Murphy type burette, 9. float, 10. bracing ring, 11. limited object, 12. valve rods, 13. times tube for transfusions, 14. hinge, 15. contact board, 16. contacts, 17. speed regulator, 18. filters, 19. syringe needles.
The specific embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
Fig. 1, embodiment illustrated in fig. 2 in, the alarm infusion apparatus that originally dams is by needle for inserting bottle 1, upper tubing 2, tube for transfusion joint 3, connection tube 4, capsule bag 6, Murphy type burette 8, float 9, bracing ring 10, limit thing 11, valve rod 12, tube for transfusion 13, hinge 14, contact board 15, contact 16, speed regulator 17, filter 18 and syringe needle 19 etc. are formed down.Wherein, needle for inserting bottle 1, upper tubing 2, following tube for transfusion 13, speed regulator 17, filter 18 and syringe needle 19 are prior art.Upper channel 5 that is provided with in by tube for transfusion joint 3 and connection tube 4 in the lower end of upper tubing 2 and the lower channel 7 that is positioned at below this upper channel are communicated with the inner chamber of capsule bag 6, the effect of upper channel 5 is to be beneficial to gas turnover capsule bag 6, and the effect of lower channel 7 is to be beneficial to medicinal liquid and discharges from capsule bag 6.The outside adhesion of capsule bag 6 has two contact board 15, and the middle part that the other end of these two contact board 15 is equipped with 16, two contact board 15 of a circuit contact respectively connects by hinge 14.When work, after the medicinal liquid from upper tubing 2 flows to end, medicinal liquid shrinks capsule bag 6 to the pressure reduction of capsule bag 6, and the contraction of capsule bag 6 connects two parts of pair of contact 16 by the action of contact board 15, thereby can alarm signal can be sent to alarm device by lead.Tube for transfusion joint 3 is communicated with the top cover inlet opening of Murphy type burette 8 by connection tube 4, is provided with one in the Murphy type burette 8 by float 9 and the valve plug that is connected below this float, the valve rod 12 of taper that the lower end is constitutes, and float 9 is the sealed plastic capsule of hollow.When work, when in the Murphy type burette 8 liquid level when descend surpassing desired location, this valve plug lower end can be blocked on the liquid outlet of Murphy type burette 8, makes to keep certain medicinal liquid in the Murphy type burette 8, allows make things convenient for the nurse to change medicinal liquid after reporting to the police to continue transfusion or in time come to finish transfusion.The valve rod 12 outer bracing rings 10 that are contained in Murphy type burette 8 inwalls that are provided with, on the valve rod under this bracing ring 12, be connected with shaft-like limited object 11, when work, when in the Murphy type burette 8 liquid level when rise surpassing desired location, shaft-like limited object 11 will be stuck in bracing ring 10 times, open excessive with the restriction valve plug.
