Description
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of continuous schedule analgesia medicinal liquid infusion appliance.
As everyone knows, in the treatment of postoperative pain, cancer of late stage pain and various intractable pains, intravenous injection anesthesia, analgesic are a kind of means commonly used clinically, and it can alleviate patient's misery effectively, allow patient comfort, happiness, improve the security.At present, both at home and abroad methods such as micro-continuous schedule medicine analgesia and patient-controlled medicine analgesia that adopt realize more.Announced the automatically continuous killer injecting pump of a kind of disposable trace as patent 98201655.7, it is made up of drug storage medicine injecting device, medicinal liquid conduit and flow controller, the drug storage medicine injecting device is made up of housing and medicine bag, medicine bag is fixed on the medicine bag holder of lower house, flow controller is fixed on the medicinal liquid conduit, its complex structure, and it is stable inadequately, accurate to inject dose, maintenance needs knack, and price is also more expensive.
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure, light is provided, and injection speed is even, stable, and effective, cost is low, continuous schedule analgesia medicinal liquid infusion appliance easy to use.
For achieving the above object, a kind of continuous schedule analgesia of this utility model medicinal liquid infusion appliance, it is provided with drug storage capsule, conduit, filter, entry needle joint, it is characterized in that two drug storage capsule outlets are connected with filter by conduit and threeway, be connected with check valve in the conduit between threeway and the outlet of drug storage capsule, conduit is provided with flow-stopping clip, is connected with micro tube between filter and entry needle joint.
This utility model drug storage capsule is the soft capsule with elastic contractile force, and the internal diameter of micro tube adopts tiny aperture, and its internal diameter is 0.001～0.2mm.During use, need not use power supply, only rely on the capsular elastic contractile force of drug storage, accurate constant voltage continues to drive injects medicinal liquid, and by micro tube control flow, evenly administration, it is big, easy to use that two drug storage capsules are equipped with dose.This utility model simple structure, light, injection speed is even, stable, good analgesic effect.
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
As can be seen from Figure 1, a kind of continuous schedule analgesia of this utility model medicinal liquid infusion appliance, it is provided with liquid storage capsule 1, conduit 2, filter 7, entry needle joint 9 etc., two drug storage capsule 1 outlets are connected with filter 7 by conduit 2 and threeway 5, be connected with check valve 4 in the conduit 2 between threeway 5 and 1 outlet of drug storage capsule, conduit 2 is provided with flow-stopping clip 3, and 9 of filter 7 and entry needle joints are connected with micro tube 8.
This utility model drug storage capsule 1 is the soft capsule with elastic contractile force, and the drug storage capsule increases gradually owing to the injection of medicinal liquid, and produces the pressure to medicinal liquid, this pressure is about constant voltage, during use, need not use power supply, only rely on the capsular elastic contractile force of drug storage, accurate constant voltage continues to drive the injection medicinal liquid.Drug storage capsule 1 inlet is provided with check valve 12 and helmet 11.Check valve 4 drug storage capsule 1 outlet dorsad is to guarantee the one-way flow of medicinal liquid.Conduit 2 is provided with flow-stopping clip 3, and flow-stopping clip 3 is to be used for controlling respectively the outflow of two drug storage capsule medicinal liquids.The ultra-fine filter membrane material aperture that filter 7 adopts is even, careful, good filtration effect.Also be provided with sliding folder 6 on the conduit 2 between threeway 5 and the filter 7, be used for controlling flowing of medicinal liquid.9 of filter 7 and entry needle joints are connected with micro tube 8, and the internal diameter of micro tube 8 adopts tiny aperture, and its internal diameter is about 0.001～0.2mm, are used for controlling flow, realize trace, evenly administration.This utility model also is provided with helmet 10 on entry needle joint 9, so as not to contaminated, guarantee safe in utilization.
When this utility model uses, at first, clamp flow-stopping clip 3, close transfusion perfusion circuit, the medicinal liquid for preparing is injected drug storage capsule 1 through drug storage capsule inlet with syringe.Open flow-stopping clip 3, rely on the capsular elastic contractile force of drug storage, medicinal liquid enters micro tube 8 by check valve 4 and threeway 5 and filter 7.Two drug storage capsules can flow out by flow-stopping clip and check valve control medicinal liquid respectively.Micro tube 8 control flows, make medicinal liquid on request trace, evenly provide, last medicinal liquid flows to injection needle through entry needle joint 9, enters human body.This utility model both can adopt a drug storage capsule, also can adopt two drug storage capsules, and it is big that two drug storage capsules are equipped with dose, and dosing, use, control are conveniently.
The utility model simple structure, light, rate of administration is even, stable, and the time is lasting, the pain relieving effect Fruit is good. Can be widely used in the treatment of postoperative pain, cancer of late stage pain and various intractable pains.
