Abstract
The utility model relates to an application technique of clinical medicine. Particularly an automatic control safety analgesia device for relieving patients' pains, which comprises a medicine storage bag, an injector, a medicine transfusing pipe and an injecting needle, wherein, the medicine storage bag and the medicine transfusing pipe of the injector are connected by a capillary pipe; the injector which is composed of a cylinder, a piston and a compression spring is a negative-pressure continuous injector which is designed according to the matching relationship of the negative-pressure thereof and the resistance force of the capillary pipe. The utility model which can realize patients' automatic control the timing and quantitative medicine supply avoids the reaction of drug intoxication and has the advantages of high safety and portability.
Description
This utility model relates to the clinical medicine application technology, and is particularly a kind of for removing the self-control safety analgesic apparatus of patient's pain.
Disease often causes patient's pain, for removing pain, need by medical care repeated multiple times injection analgesic, but often injectable drug can not be timely, causes analgesic effect not good enough.Chinese patent 93208989 discloses a kind of lasting infusion appliance, it be by reducer under the effect of compression pump in body for medicine, obviously reducer might make medicinal liquid enter in a large number in the body once out of control, causes drug intoxication.
The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, and provide a kind of safe and reliable, easy to carry, by the patient oneself control timing self-control safety analgesic apparatus of injection voluntarily.
The purpose of this utility model be achieved in that it by storage medicated bag, injector, grug transportation tube, entry needle is first-class forms, is connected by capillary tube between the grug transportation tube of this storage medicated bag and injector, this injector is made of cylinder barrel, piston and compression spring and is the lasting injector of negative pressure that matching relationship designs by its negative pressure and resistance capillaceous.
Therefore this utility model compared with prior art because injector is matching relationship by principle of negative pressure design and its negative pressure with resistance capillaceous, can realize that the patient controls timing, dosed administration voluntarily, has avoided the drug intoxication reaction.The storage medicated bag adopts gentle material to make, can next to the shinly place, and injured skin not, package unit is safe and reliable, easy to carry.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail this utility model is described in detail.
This utility model embodiment is made up of storage medicated bag 1, capillary tube 2, injection needle 3, unidirectional flap valve 4, grug transportation tube 5 and injector.Be connected by capillary tube 2 between the grug transportation tube 5 of storage medicated bag 1 and injector, this injector is constituted and is by the resistance of its negative pressure and capillary tube 2 the lasting injector of negative pressure of matching relationship design by cylinder barrel 6, piston 7 and compression spring 8, designed matching relationship regulation, allowed the 0.5ml medicinal liquid to be full of injector in per 5 minutes, the patient was by pushing injector piston 7 can inject 0.5ml in body medicinal liquid in per like this 5 minutes.For preventing that medicinal liquid emptying from causing blood back, this utility model is equipped with unidirectional flap valve 4 on the grug transportation tube 5 that connects injection needle 3.Storage medicated bag 1 of the present utility model is made by softish plastic material.
Claims (2)
1, a kind of self-control safety analgesic apparatus, comprise storage medicated bag (1), injector, grug transportation tube (5), injection needle (3), it is characterized in that storing between the grug transportation tube (5) of medicated bag (1) and injector and be connected by capillary tube (2), this injector is constituted, and is the lasting injector of negative pressure that matching relationship designs by the resistance of its negative pressure and capillary tube (2) by cylinder barrel (6), piston (7) and compression spring (8).
