Description
Technical field
The Murphy tube assembly with reduction liquid level function that the present invention relates to use in a kind of infusion process.
Background technology
Traditional transfusion device is to be made of perforator, catheter, airway, Murphy tube (being commonly called as dropping funnel), by-pass cock, syringe needle.This transfusion device does not have the automatically drip-stopping function, in case after medicinal liquid is failed only, if will causing in blood back, the blood vessel, untimely processing enters air, even cause malpractice.A kind of transfusion device automatically drip-stopping, alarm device are provided among the CN101234219, be by perforator, catheter, airway, power-assisted air bag, dropper, be located at cursory, the sealed elastic cover that is located at the dropper end opening in the dropper, catheter, Murphy tube, tube for transfusion, the by-pass cock, the syringe needle that are located on the tube for transfusion consist of.In actual the use, when first bottle of transfusion finished, because liquid level descends in the dropper, cursory sinking was with the sealing of sealed elastic cover.When changing second bottle (bag) when changing dressings, close first by-pass cock, with hands one or many extruding Murphy tube, air compressing jack-up is cursory, then opens by-pass cock, and the medicinal liquid in the dropper will flow into Murphy tube through catheter, continues transfusion.When defeated second bottle or the 3rd bottle liquid medicine begin, because catheter, residual medicinal liquid when the airway internal memory leaves first bottle (bag) transfusion gas often can occur and block up phenomenon; air guide channel is blocked; can't normal infusion, just can get through air flue by power-assisted air bag, thus normal infusion.In extruding Murphy tube process, sometimes once pushing cursory being difficult to floats, and just can adopt the way of repeatedly pushing Murphy tube can make at last and cursoryly float.Since repeatedly push Murphy tube have the part medicinal liquid in the dropper sealing shroud and cursory gap enter Murphy tube, cause that liquid level rises in the Murphy tube, make Murphy tube Air quantity not sufficient, cursory can't jack-up, can not normal infusion.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly can reduce liquid level in the Murphy tube at transfusion bottle (bag) when changing dressings more, guarantees normal infusion, and easy to operate, the Murphy tube assembly with reduction liquid level function of reliable operation.
The Murphy tube assembly with reduction liquid level function that the present invention relates to, comprise Murphy tube, be connected to the catheter of Murphy tube entrance, its special character is: be provided with the drain switch at catheter, on catheter or the Murphy tube porch be provided with air inlet pipe, be provided with air filtering core in the air inlet pipe, be provided with the air inlet switch that to reset in air inlet pipe.
Described drain switch and air inlet switch are comprised of a permutator, and air inlet switch is closed when opening the drain switch, and the drain switch cuts out when opening air inlet switch, thereby realize the automatic conversion of drain and air inlet.
An outlet is merged in described catheter outlet and air inlet pipe outlet.
Described Murphy tube entrance is bonded with the entrance end cap, and described catheter outlet and air inlet pipe outlet are connected to arrival end and cover.
Described permutator is by overcoat, be located at the thrust piece in the overcoat, the first spring that is located on the spring base of corresponding thrust piece inboard in the overcoat consists of, draw for button and by the overcoat port in the described thrust piece outside, be provided with bayonet lock at the inboard outer wall of thrust piece, corresponding bayonet lock position is provided with locating slot on outer casing inner wall, on the coat along axially being respectively equipped with two perforation with thrust piece, thrust piece be provided with outside to put a perforation corresponding, the through hole that is misplaced with another perforation, described catheter and air inlet pipe are passed by through hole on the thrust piece that puts perforation and correspondence outward respectively, and described locating slot is adjacent with perforation.
Described through hole is one, and described catheter 1 and air inlet pipe 3 are passed through this through hole respectively.
Described drain switch is push switch or clamped-in style switch.
The described push switch that resets is by base, gland, is located at the second spring between base and the gland, is located at the sealing gasket on the gland, be located at the air inlet pipe import and be provided with the end cap in centre pilot hole, the button that is installed in end cap central bore consists of, described base is provided with passage, the button upper end is drawn by the centre bore of end cap, is provided with the inlet channel that communicates with the air inlet pipe inner chamber around the described end cap corresponding button.
Guide through hole conical surface matched in clearance in described button bottom and the end cap.
Described airway radially distributes.
The invention has the beneficial effects as follows:
1, owing to being provided with air inlet pipe, when repeatedly more bottle is changed dressings transfusion, close the drain switch, open air inlet switch with hand operated, can make that air is smooth and easy to be entered in the Murphy tube, because sufficient air capacity is arranged in the Murphy tube, liquid level can drop to correct position under the atmospheric pressure effect, for again more bottle change dressings and obtain sufficient air capacity, make and cursoryly float, thereby create the condition of necessity for normal infusion; After closing air inlet switch, open the drain switch, thereby transfusion is normally carried out;
2, owing to adopting the air inlet switch that to reset, can prevent the transfusion operation personnel, forget and close air inlet switch and cause in blood back or the air intravasation and cause malpractice.
3, owing to being provided with the drain switch, the drain switch is in closed condition when air inlet, air is smooth and easy to be entered thereby make, prevent that medicinal liquid from continuing to flow into Murphy tube liquid level is raise, in case being full of Murphy tube, the rising of medicinal liquid liquid level will make operator and monitoring personnel can't observe the medicinal liquid flow velocity, very easily cause malpractice, can prevent that medicinal liquid from entering air inlet pipe and causing medicinal liquid outflow waste simultaneously.
4, adopt the transfusion device cost of this Murphy tube assembly low, easy to operate when infusing, reliable operation.
