Abstract
An automatic alarm infusion set belongs to medical care infusion equipment. The utility model which comprises an air intake tube, an infusing tube and a Murphy's dropper is characterized in that another Murphy's dropper is connected in series between the infusion tube and the Murphy's dropper. The Murphy's dropper is connected with an air pressure point touch switch by a connection tube. The air pressure point touch switch consists of an airtight cavity with elasticity film, a sliding block supported by a sliding stop block, a guiding rod linked therewith, a location bracket, a base plate and a point touch switch which are sealed in a shell body and overlapped by sequence. The point touch switch is electrically connected with a power supply, a control switch and an alarm. The automatic alarm infusion set has the advantages of convenient using and simple structure. The infusion device is air-tightly separated from the alarm device so that the security and sanitation of infusion can be guaranteed. The alarm system can be used repeatedly to provide convenience for medical staff and families of patients as well as to reduce medical accident.
Description
Technical field
This utility model belongs to the medical infusion apparatus, relates in particular to a kind of transfusion device with automatic warning function.
Background technology
Patient is when adopting transfusion device to infuse, need the on-the-spot nurse of nurse or families of patients, if liquid is totally lost and is failed in time to pull up infusion needle, just make the air admission human vas that is mingled with in the tube for transfusion easily, in addition because the pressure of human vas, also occur blood easily along tube for transfusion refluence phenomenon, cause malpractice, influence patient health.The Chinese patent ZL 96250753.9 of bulletin in 1998 provides a kind of disposable alarm infusion apparatus, comprise tube for transfusion, exhaustor, Murphy tube, speed regulator and Guan Gai, it is characterized in that between Murphy tube a and speed regulator, being provided with side by side Murphy tube b and Murphy tube c, Murphy tube b and tube for transfusion series connection, and by linking to each other with Murphy tube c communicating pipe, Murphy tube c top is provided with to manage to cover establishes a level control switch for water that is electrically connected with alarm device in it.Because no any spacer assembly between liquid in the Murphy tube c and the liquid carried to patient by tube for transfusion, tube for transfusion is contaminated easily, influences therapeutic effect and patient health.
The utility model content
The purpose of this utility model is to provide a kind of automatic alarm type transfusion device, and alarm device and infusion set are isolated fully, have guaranteed transfusion safety and health.
The scheme that this utility model is taked is: a kind of automatic alarm type transfusion device, comprise air inlet pipe, tube for transfusion and Mohs dropper, it is characterized in that polyphone Mohs dropper 4 between tube for transfusion 2 and Mohs dropper 5, Mohs dropper 4 touches switch by communicating pipe 12 and pressure point and is connected, pressure point touch switch by be sealed in the slide block 17 that the closed chamber that has elastica 11 21 stacked successively in the housing, limited slip block 10 support, guide rod 9, locating rack 16, substrate 15 and the some contact switch 6 with its interlock constitutes, point touches switch 6 and is electrically connected with power supply 19, gauge tap 20 and alarm 18.
Hospital's nurse caution system can be in parallelly inserted at the two ends of some contact switch 6, and the nurse just can understand the transfusion situation by existing sick bed nursing system.One end lead of some contact switch 6 is drawn by metal spring 7, and the other end is drawn by conduction feeler lever 13.Slide block 17 supports by being arranged on the limited slip block 10 that pressure point touches on the switch wall, and slide block just can not cause damage to elastica like this.The point contact switch of closed chamber (21) and band slide block is connected, and during use its alarm device with the slide block transmission is connected; Itself and disposable transfusion device can be disposed after the use, the alarm device of slide block transmission can be reused, and can not cause any pollution to patient and facility, more helps health care.
The beneficial effects of the utility model are: easy to use, simple in structure, can guarantee transfusion safety and transfusion health, and warning system can repeatedly be used, and makes things convenient for medical personnel and families of patients, reduces malpractice.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation that pressure point is touched switch in this utility model;
Fig. 3 is circuit theory diagrams of the present utility model.
Among the figure: 1. air inlet pipe, 2. tube for transfusion, 3. threeway, 4. Mohs dropper, 5. Mohs dropper 6. touches switch, 7. back-moving spring, and 8.A holds lead, 9. guide rod, 13. conduction feeler levers, 11. elasticas, 12. communicating pipes, 10. limited slip block, 14.B holds lead, 15. substrates, 16. locating rack, 17. slide blocks, 18. alarms, 19. power supply, 20. gauge taps, 21. closed chamber.
The specific embodiment
Embodiment begins before the transfusion, gauge tap 20 disconnects, point contact switch 6 is closed, when beginning to infuse, because the liquid level rising produces normal pressure in the Mohs dropper 4, elastica 11 promotes slide blocks 17 and guide rod 9 moves upward, and will put contact switch 6 and open, at this moment closed gauge tap 20, warning system is in pre-alarm state.After liquid was totally lost in the infusion bottle, the air pressure in the Mohs dropper 4 was reduced to atmospheric pressure, and elastica 11 restores to the original state, slide block 17 and guide rod 9 move downward, and some contact switch 6 resets, and circuit is connected, alarm 18 begins to report to the police, and reminds the nurse personnel in time to pull out infusion needle.Open gauge tap 20, alarm 18 promptly stops to report to the police.The pressure point contact switch can repeatedly use, and the closed chamber 21 and communicating pipe 12, the transfusion device that have elastica can be disposed, and can not cause any pollution to the liquid in the next tube for transfusion like this.
