Description

Automatic transfusion device

Technical field

This utility model relates to a kind of medical infusing device, particularly has the automatic transfusion device of warning function.

Background technology

Hospital all adopts ampoule is uphang on support when patient being implemented the transfusion treatment now, according to the liquid level differential pressure principle, makes in the injection input body.The shortcoming of this method is: the one, and patient's range of activity is subjected to limitation, particularly when patient infusion, goes into very inconvenience of behavior such as lavatory; The 2nd, tube for transfusion is long, causes certain waste; The 3rd, suspension holdfast places in the ward i.e. occupation of land side, also hinders doctor's diagnosis and treatment work.

Summary of the invention

Goal of the invention of the present utility model provides a kind of simple in structure, and is easy to use, cheap, and the automatic transfusion device of tool warning function, to remedy existing deficiency.

To achieve the above object of the invention, this utility model adopts technical scheme to be: automatic transfusion device is by cylindrical shape skin purt, balance tube, and alarm device is formed, and it is characterized in that described cylindrical shape skin purt is made of last purt plate, purt seat, skin tube, extension spring, inlet valve etc.; The described purt plate center of going up is provided with the circular hole suitable with the ampoule external diameter, and going up of plate is respectively equipped with the self-contained battery box to the appropriate location, the screw of buzzer; The center of described purt seat be provided with can be by the medicament bottleneck circular hole, a side of purt seat is provided with the screw that inlet valve is installed, the opposing party is provided with the screw of installation balance tube, purt seat following to being provided with three feets; Described skin tube (inner core, urceolus) all adopts cortex (or other material) material to make, be pressed into and unfold shape, inner core internal diameter size is being advisable by ampoule, and the urceolus diameter is slightly less than purt plate and purt seat diameter, interior crust tube with binding agent respectively with last purt plate, the purt seat is fixedly connected; The internal diameter of described extension spring is slightly larger than endothelium tube external diameter, upward and downward respectively with last purt plate, the purt seat fixes, and is installed in the pump; Described inlet valve (prior art) but be that air inlet and the check valve that can not exit are installed on the purt seat.By body, balance valve, the sealing ring of holding one's breath constitutes at described balance tube, and described body is equipped with external screw thread, matches with the installation screw of purt seat; Described balance valve (prior art) is that the control capacity is a rated value, makes the air pressure in the external ampoule be in the weighing apparatus pressure condition, and the inlet end of balance valve is fixedlyed connected with the sealing ring of holding one's breath, and the outlet side is connected with the body upper end; The described sealing ring of holding one's breath is can guarantee good air-tightness when the top is stopped up by the plane; Balance tube is installed on the purt seat by sealing member, and balance valve is in the skin purt, the height of rotation body scalable balance tube, and the lower end of balance tube is connected with the air inlet pipe of tube for transfusion.Constitute by buzzer, aneroid battery, warning contact at described alarm device, the warning contact be installed on go up in the pump on the purt plate and with balance tube corresponding position up and down, the size of following contact is advisable can cover the sealing ring of holding one's breath, aneroid battery, buzzer are installed in respectively on the purt plate, respectively the three are connected in order with lead.

Operation principle of the present utility model is: during use, the air inlet pipe of tube for transfusion is connected with balance tube, ampoule is inverted in the pump and with tube for transfusion by last purt plate and is connected, height when again balance tube being adjusted to medicament and being totally lost, at last, purt plate in the slow pull-up of the pulling force that overcomes extension spring makes air enter in the pump till reach terminal point from inlet valve.When unclamping the purt plate, pump is under the active force of extension spring, and gas forms compressed air in the tube, slowly transport to ampoule through balance valve, medicament is at the uniform velocity imported in the body by tube for transfusion, when last purt plate when touching mutually with the sealing ring of holding one's breath of balance tube, promptly the air inlet of the balance tube contact of being reported to the police covers and stops up, transfusion stops, because blood pressure is in identical state with outer air pressure in the body, also prevents backflow of blood, simultaneously, reporting to the police up and down, contact contacts alarm work.Owing to adopted technique scheme, this utility model is compared with existing, and following advantage is arranged: (1) is simple in structure, and is easy to use, and cost is low; (2) human action of transfusion seasonal disease is unrestricted; (3) liquid is totally lost and can be stopped automatically, and can warn.
