Description
The present invention relates to a kind of armarium, specifically, relate to a kind of being used for patient's wound is carried out local injection pure oxygen and the Oxygen infusion device that sprays medicine.
Medically, no matter be the wound that the wound of causing injury because of extraneous factor or surgical operation and shaping and beauty occur, patient has long convalescent period at post-operative wound, and the difference of many patients because of body constitution is arranged, edema in wound recovery process, can occur and after wound recovers, abnormal pigmentary deposit on the skin trace hypertrophy or Pigmented phenomenon can occur.In clinical treatment, it is found that, with the auxiliary treatment that the pure oxygen of purity more than 99% carries out oxygen supplement to patient's wound, can shorten the healing time of wound greatly, abnormal pigmentary deposit on the skin trace hypertrophy or Pigmented phenomenon occur after alleviating the edema of wound and reducing wound healing.At present, the auxiliary treatment that patient is carried out pure oxygen all is to adopt the method for hyperbaric oxygen chamber.After patient entered into hyperbaric oxygen chamber, the oxygen that feeds 0.1～0.2MPa pressure continued to carry out 2 hours treatment.Because the treatment to patient only is to carry out local oxygen enriching or spray medicine in its wound, and uses hyperbaric oxygen chamber therapy, most oxygen all are not fully used and have been wasted.So use the Therapeutic Method of hyperbaric oxygen chamber, the one, patient expense height, burden are greatly, the 2nd, hyperbaric oxygen chamber is closed and is sealed the back pressurization and has certain danger, the 3rd, equipment price is more expensive, the 4th, the maintenance of equipment, maintenance require high, and the 5th, operator must be through taking appointment with certificate after specialized agency's training.Have only some big medical institutions that this armarium of hyperbaric oxygen chamber is just arranged now, concerning most patient, owing to be subjected to the restriction of various conditions can't obtain this effective auxiliary treatment.
In order to solve the weak point of present hyperbaric oxygen chamber therapy, for the wound that makes extensive patients can both be treated better, be recovered, the invention provides a kind of Oxygen infusion device, this Oxygen infusion device can not only carry out the local injection pure oxygen to the patient wound, can in the process of injection pure oxygen, spray medicine or active nutritional material simultaneously to the wound, and simple, convenient, the safety of this Oxygen infusion device, the medical worker is as long as need not can use this Oxygen infusion device through special training by the requirement of operation instructions.
The technical solution adopted in the present invention is: use medical pure oxygen and the required medicinal liquid (or active nutritional material) of treatment produced by national standard, by a control chamber of forming by atmospheric control and circuit control system, atmospheric control is by pressure switch, pressure transducer, flow transducer, electromagnetic valve, flow control valve, Pressure gauge, pneumatic components and parts such as booster pump and sebific duct are formed, and circuit control system is by on and off switch, transformator, bridge rectifier, electric capacity, electronic component such as circuit of three-terminal voltage-stabilizing integrated and LCD MODULE is formed.Pneumatic system is under the control of Circuits System, realization is to the input of oxygen and medicinal liquid, the control of output, and in use consumption, flow, time are controlled and demonstration in real time, can select simultaneously automatic, manual, foot-operated three kinds of modes to control the injection of injector head as required, and under automatic control state, also can select continous way injection, pulsed to spray dual mode.The oxygen or the medicinal liquid (or active nutritional material) of output are transported to injector head via sebific duct, oxygen and medicinal liquid (or active nutritional material) the buffering hybrid chamber through buffering, mix after, the aperture from the nozzle is ejected into patient's wound again.
The invention has the beneficial effects as follows:
The oxygen or the medicinal liquid that eject from aperture form the jet-like fluid, produce very big pressure in wound surface, and oxygen or medicinal liquid are injected in the skin basal layer;
The mode that wound surface is sprayed has two kinds, and the one, closed continuous injection, another is open impulse jet;
Safe, nothing danger;
The patient expense is low, burden is little;
Volume is little, in light weight;
Simple in structure, easy to operate, do not need special training
Used components and parts all can be in market purchasing.
The present invention is further described below in conjunction with drawings and Examples.
