Abstract

The utility model relates to an adjustable self-control analgesia pump, in particular to an acesodyne automatic syringe, which consists of a hanging nip, a casing, a silica gel liquid-storage bursa, a connecting tube, a liquid-infusing mouth, an infusion catheter, a controller, a flow-controlling machine, a switch, a self-control key, an automatic counting display screen, a load medicine-infusing mouth and a transfusion outlet. The utility model is characterized in that the silica gel liquid-storage bursa in the casing is communicated with the controller through the infusion catheter; the controller is provided with two switches, a self-control key, an automatic counting display screen and a load medicine-infusing mouth; the outlet at the other end of the controller is communicated with other end infusion catheter whose tip is connected with the transfusion outlet. The utility model has the advantages of rapid and convenient utilization and rapid reflection and the individual difference using analgesics decreases to the least level.

Description

Adjustable controlled analgesia pump

This utility model relates to the pain relieving automatic injector.

Pain is perplexing the mankind always, also is one of difficult medical problem that does not solve fully as yet so far.At present, there is the cancer patient more than 1,800,000 in China, wherein have 70% for end-stage patients with having an intense pain, every day, nearly 3,500,000 people in the whole world suffered the torment of pain.Aspect the acute pain treatment, nearly 50% postoperative patient exists the infull phenomenon of analgesia.China is maximum in the world developing country, owing to each reason, comprises the reason of aspects such as economy and Medical Technology and traditional culture difference, pain therapy is paid attention to not enough.Pain is brought not only for patient's physical and mental health and is had a strong impact on, even can make patient lose the courage of life.In order to allow the mankind live more blessedly, it is the problem that needs to be resolved hurrily in China's curative activity that more efficiently analgesia therapy is provided.The bad phenomenon of easing pain clinically is to lack good analgesic and suitable administering mode mostly.Oral and the intramuscular administration of tradition to too mechanical on its dosage, approach, time and the method, can not adapt to patient's individual variation timely.At the beginning of the eighties, first controlled analgesia pump (PCA) comes out, and patient can reach analgesia fully according to the analgesia needs oneself control administration of controlling oneself.Microelectric technique has advanced the development of PCA greatly over past ten years.Over nearly 2 years, the PCA technology has also obtained than extensive use in China big city and large hospital, but vast basic hospital still can not penetration and promotion, mainly is economic cause.At present, 2 class analgesia pumps are arranged clinically, an electron-like analgesia pump, function is complete, and controllability is good, is difficult to be widely used in clinical but cost an arm and a leg, and is that vast pain patients removes painful.Another kind of property is an analgesia pump, and advantage is to use conveniently, but exists adjustability poor, can not add up the automatic control number of times, and health and pain degree administration as required that can not be concrete according to patient often have the infull phenomenon of analgesia, and price is also than shortcomings such as costlinesses simultaneously.

The purpose of this utility model is to regulate the dosage that continues medication by flow-controlled device, and comes accumulative total automatic control compression number with counting display screen automatically, to adapt to different patients' needs oneself control administration.

The novel purpose mode of passing to down of this reality realizes:

Adjustable controlled analgesia pump, by hang folder, shell, silica gel reservoir, connection tube, liquid injection port, tube for transfusion, modulator, flow-controlled device, switch, from control key, count display screen, load medicine-pouring port, transfusion outlet automatically and form.

Elaborate below in conjunction with accompanying drawing:

Hang folder 1 a end among the figure at shell 2, and be connected with 2, silica gel reservoir 3 is in shell 2, and be connected with an end of connection tube 4, connection tube 4 has a

liquid injection port

5,4 to communicate with tube for transfusion 6 outside shell 2, and tube for transfusion 6 communicates with modulator 7, load medicine-pouring port 8 is arranged on the modulator 7, three flow-controlled devices 9 are arranged in the modulator 7; 7 outer two switches 10 are arranged, from control key 11 and one counting display screen 12 automatically, load medicine-pouring port 8 with communicate from control key 11, other end outlet communicates with another section tube for transfusion 6 in the regulation and control 7,6 end is connected with to infuse and exports 13.

Material and specification: (1) shell (plastics, long 13.5cm, diameter 4.5cm); (2) liquid injection port (plastics); (3) reservoir (silica gel); (4) load medicine-pouring port (plastics); (5) transfusion outlet (plastics); (6) connection tube and tube for transfusion (plastics or silica gel); (7) modulator (the special flow control device of duroplasts).

During operation, remove the liquid injection port helmet earlier, the medicinal liquid for preparing is injected in the silica gel reservoir with syringe finish dosing.Then, open transfusion outlet aerofluxus, and push from 1-2 rear enclosed transfusion of the control key port of export.Inject the load dose to the automatic control reservoir from the load medicine-pouring port again, the port of export of will infusing links to each other with patient's trocar, and push from control key and inject loading to patient, automatically can write down on the counting display screen and inject loading and the number of times of pushing from control key, set the switch that continues amount of infusion according to the state of an illness again.When switch eased pain outside being used for firmly, 3 kinds of dosage of may command were respectively; 3ml/h, 1ml/h and 4ml/h can only open wherein a kind of as required or open 2 kinds simultaneously; As being used for vein, dosage is respectively 2ml/h, 0.5ml/h and 2.5ml/h.

Advantage of the present utility model:

1, continues the adjustability of flow: can regulate within the specific limits lasting flow according to patient's pain situation, by transferring Joint continues the analgesia requirement that flow can satisfy different patients, has compared obvious innovation with existing disposable PCA at present commonly used.

2, the convenience of load administration: only need press from control key and just can inject load, need not carry syringe.

3, by counting display screen automatically, can accurately show the number of times of pushing from control key after pushing at every turn.

4, aesthetic in appearance, easy to carry, high safety, cheap.
