Abstract
The utility model relates to a patient self control analgesic persistent injector, which is composed of a pressure pump part and a flow control part, wherein, the flow control part comprises a persistent injecting channel and a gap injecting channel, wherein, the persistent injecting channel is connected with a pressure pump (9) through a joint (7); a connecting catheter is connected with a joint (8) through a three-way joint (1), a flow controller (2) and a three-way joint (3); the gap injecting channel is connected with the joint (8) through the three-way joint (1), a flow controller (4), a sacculus rotundus (5), a one-way valve (6) and the three-way joint (3). when the patient feel pain, the sacculus rotundus (5) can be pressed by hands to squeeze physic liquor in the sacculus rotundus into human body through the one-way valve (6), the three-way joint (3) and the joint (8). The utility model has the advantages of simplicity, practicality, self control analgesia, etc.
Description
This utility model relates to medical apparatus and instruments, be specifically a kind of can be by the lasting infusion appliance of patient oneself control.
Common lasting infusion appliance is by reaching analgesia toward venous patient or epidural space injection analgesia medicinal liquid constantly.But patient can not be according to the injection rate of pain situation oneself control medicinal liquid.
The purpose of this utility model promptly is at existing common lasting infusion appliance, can not be controlled the problem of the aspects such as injection rate of medicinal liquid by patient oneself, and provide a kind of patient-controlled analgesia type to continue infusion appliance.
The purpose of this utility model is achieved through the following technical solutions: a kind of patient-controlled analgesia type continues infusion appliance, partly form by the compression pump part and the flow controller that comprise the rubber bile duct (10) in compression pump (9) and the compression pump (9), said flow controller partly comprises lasting the injection and two passages of gap injection, wherein continue the injection channel and be connected with compression pump (9) by joint (7), connecting duct is connected with joint (8) through three way cock (1), reducer (2), three way cock (3) then; Another passage is the injection channel at intermittence, is connected with joint (8) through three way cock (1), reducer (4), sacculus (5), check valve (6), three way cock (3).
The utlity model has following advantage and effect:
In order to realize patient-controlled analgesia, on the basis that continues infusion appliance, additional intermittent injection device, when promptly getting the dosage more on the low side and continue to inject than safe dose, when patient feels pain, can replenish injection potion medicine by the intermittent infusion device.The utlity model has simply, practical, and can make the advantage of aspects such as patient-controlled analgesia.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structure chart that patient-controlled analgesia type of the present utility model continues infusion appliance
Be described further below in conjunction with drawings and Examples:
As shown in Figure 1, whole lasting infusion appliance is made up of compression pump and flow controller two parts.Wherein: one, compression pump part: comprise rubber bile duct 10 in compression pump 9 and the compression pump 9, after medicinal liquid charged into from pump intake by syringe, rubber bile duct 10 expanded, so that made medicinal liquid be full of whole cavity in the pump.Because the elastic contractile force of rubber bile duct 10 squeezes the gallbladder inner liquid medicine outward.Two, flow controller partly comprises lasting two passages that inject and intermittently inject, wherein lasting injection channel is by joint 7 and after compression pump 9 is connected, medicinal liquid in the compression pump 9 is connected with three way cock 1 through connecting duct, and the injection needle on reducer 2, three way cock 3, joint 8 is injected into human body constantly; Another is the injection channel at intermittence: it is the injection needle on three way cock 1, reducer 4, sacculus 5, check valve 6, three way cock 3 and joint 8, enters human body off and on.Owing to the buffer action of check valve 6, clearance channel does not have medicinal liquid to flow through, and only has continuous flow to pass through in continuous passage at ordinary times.When patient feels pain, push sacculus 5 with hands, make the capsule inner liquid medicine clamp-on human body by the injection needle on check valve 6, three way cock 3 and the joint 8, realize patient-controlled analgesia.By selecting different reducer 2 to control different lasting injection flow velocitys, select the different time that is full of sacculus 5 (i.e. the minimum interval that intermittently injects) by selecting different reducer 4.
Claims (1)
1. a patient-controlled analgesia type continues infusion appliance, partly form by the compression pump part and the flow controller that comprise the rubber bile duct (10) in compression pump (9) and the compression pump (9), it is characterized in that: said flow controller partly comprises lasting the injection and two passages of gap injection, wherein continue the injection channel and be connected with compression pump (9) by joint (7), connecting duct is connected with joint (8) through three way cock (1), reducer (2), three way cock (3) then; Another passage is the injection channel at intermittence, is connected with joint (8) through three way cock (1), reducer (4), sacculus (5), check valve (6), three way cock (3).
