Abstract
The utility model relates to a medical self-closing type infusion set, which solves the problem that a conventional infusion set cannot be closed by self. The medical self-closing type infusion set comprises a drip tube and an infusion tube, wherein a floater is arranged in the drip tube; and the diameter of the upper end of the floater is smaller than that of an inner wall of the drip tube and is greater than that of the infusion tube. The medical self-closing type infusion set can be closed automatically when transfusion is finished nearly, can stop the transfusion, and is simple, safe and reliable to operate.
Description
Technical field
This utility model relates to a kind of transfusion device, a kind of specifically medical automatic close-type transfusion device.
Background technology
At present, generally adopt the gravity transfusion device to patient transfusion, when infusing, no matter the time how long at every turn; All will someone guard, prevent that air from advancing human body along transfusion device, or liquid the blood back phenomenon occurs after being totally lost; In time do not pull out pin if liquid is totally lost, patient will be in peril of one's life, for this reason; All can have some to guard patient infusion every day in the ward, if transfusion time is long, the nurse personnel will accompany for a long time; And work as the many medical personnel of patient after a little while, and the phenomenon that medical personnel have little time to nurse will appear, bring the danger that can not in time pull out pin.And at present, used transfusion device generally adopts the disposable plastic transfusion device, though can control flow and speed, can not stop transfusion automatically, so patient when transfusion, or oneself is seeing or have the people to nurse clear-headedly, otherwise will be dangerous.
The utility model content
In order to solve the problem that existing transfusion device can not be closed automatically, this utility model provides a kind of medical automatic close-type transfusion device.When this transfusion device soon finished in transfusion, close transfusion device stops transfusion automatically, and was simple to operate, safe and reliable.
The technical scheme of this utility model is: a kind of medical automatic close-type transfusion device, comprise stilligout and tube for transfusion, and wherein, be built-in with float at described stilligout, the diameter of said float upper end is less than the inner diameter of stilligout, and greater than the diameter of tube for transfusion.
The inwall of the shape of described float and stilligout bottom coincide.
The utlity model has following beneficial effect: in above-mentioned technical scheme, stilligout is built-in with float, and the diameter of float upper end is less than the inner diameter of stilligout; And greater than the diameter of tube for transfusion, the shape of float and the lower inner wall of stilligout are coincide, and float floats on the plane of drop liquid in pipe in the drop; When transfusion finished, along with the planar decline of liquid in the dropper, float also can descend; Until the inlet that seals up tube for transfusion automatically,, both there be not liquid dirty because of tube for transfusion is plugged; Also do not have air dirty, utilize the weight of float self, air pressure in the tube for transfusion and hydraulic pressure remain stable; Pin can be guaranteed not pull out for a long time, also the blood back phenomenon can be do not occurred.This transfusion device combines existing transfusion device to realize automatic hold function, is applicable to any occasion medical infusion use and simple to operate, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Sketch map when Fig. 2 is Fig. 1 sequence number 4 float shutoff tube for transfusions.
1-liquid holding bottle among the figure, 2-surge pipe, 3-stilligout, 4-float, 5-tube for transfusion, 6-by-pass cock, 7-syringe needle.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further described:
By Fig. 1 and shown in Figure 2, this medical automatic close-type transfusion device is the improvement of on the basis of existing transfusion device, being done; Comprise the liquid holding bottle 1, surge pipe 2, stilligout 3, tube for transfusion 5, by-pass cock 6 and the syringe needle 7 that are interconnected, as shown in Figure 1, wherein; Be built-in with float 4 at described stilligout 3; The diameter of said float 4 upper ends is less than the inner diameter of stilligout 3, and greater than the diameter of tube for transfusion 5, and the shape of sealing surface and the lower inner wall of stilligout are coincide on the float 4.
As preferably, the sealing surface of said float 4 class comprise smooth surface awl point down conical or inverted truncated cone and can coincide to stilligout 3 lower inner wall and play the shape of sealing function.
In addition, said float 4 adopts nonpoisonous and tasteless and is not dissolved in the plastic production of general medicinal liquid, and its weight is suspended on the medicinal liquid under the medicinal liquid buoyancy function stably.
During normal infusion, as long as have liquid to drip downwards in the liquid holding bottle, the liquid plane in the stilligout just remains at sustained height, when transfusion finishes; Liquid plane in the stilligout will descend, and float also can descend with the liquid plane, and when the medicinal liquid in the stilligout was totally lost, the sealing surface of float will be attached on the lower inner wall of stilligout automatically; Automatically seal the inlet of stilligout, at this moment, the liquid in the tube for transfusion because of the inlet of top by shutoff, close transfusion device automatically; As shown in Figure 2, both there be not liquid not have air dirty, as long as liquid holding bottle keeps corresponding height yet; By artificial becoming flexible, air pressure in the tube for transfusion and hydraulic pressure do not remain stable float, and the liquid that remains in the tube for transfusion can't be descended; And the outstanding and position higher owing to stilligout than the position of infusing on the human body, and keep a spot of liquid in the tube for transfusion all the time, can guarantee not pull out for a long time pin; The phenomenon of blood back can not appear in the syringe needle place yet, for medical personnel's calm processing gains time, and simple to operate, safe and reliable.
Claims (2)
1. medical automatic close-type transfusion device; Comprise stilligout (3) and tube for transfusion (5); It is characterized in that: be built-in with float (4) at described stilligout (3), the diameter of said float (4) upper end is less than the inner diameter of stilligout (3), and greater than the diameter of tube for transfusion (5).
2. medical automatic close-type transfusion device according to claim 1 is characterized in that: the shape of described float (4) sealing surface and the lower inner wall of stilligout (3) are coincide.
