Description
Technical field
This utility model relates to the infusion set that medicine is used for patient's intravenously administrable clinically, and particularly a kind of patient can seal liquid-transport pipe-line automatically and prevent that outside air from entering the transfusion device of a kind of automatic flow-stop in patient's body when transfusion finishes.
Background technology
At present at medicine and hygiene fields, no matter be large hospital or Branch Clinic the patient being treated when needing transfusion, extensively adopt disposable transfusion device, the use of this transfusion device greatly reduces the fork of handing between the patient and infects.But, in using disposable transfusion device, also exist not enough, transfusion device in use as transposing infusion bottle or when medicinal liquid is totally lost, do not have the automatic flow-stop effect, if the nursing staff do not note slightly, in the air admission patient body, cause some unsafe factors.
In order to solve above-mentioned technical problem, prior art is as having proposed some technical schemes: as
China Patent No. discloses a kind of disposable use safe transfusion system for " 03260844.6 ": this transfusion device is used for the venous transfusion of medicine and hygiene fields.This transfusion device is by needle for inserting bottle, flexible pipe, flow regulator, liquid medicine filter, venoclysis needle, dropping funnel and release mechanism are formed, wherein release mechanism includes the annular shim up and down that is directly arranged in the dropping funnel bottom, and is located at the ball float that can seal down the annular shim intermediate throughholes between two pads.
China Patent No. " 200320129365.1 " discloses a kind of disposable use pressurize transfusion device, and this transfusion device is used for the venous transfusion of medicine and hygiene fields.This transfusion device is by needle for inserting bottle, flexible pipe, flow regulator, liquid medicine filter, venoclysis needle, dropping funnel and release mechanism are formed, wherein release mechanism includes the medicinal liquid access road that wine bucket lower curtate has a projection, there is a locating part dropping funnel middle and lower part, and a buoyancy aid is arranged therebetween, and buoyancy aid is embedded with the diaphragm that a latex and other soft material are made.
Above-mentioned patent is the following some shortcomings of ubiquity in actual applications: the one, and the sealing between the medicine liquid outlet of buoyancy aid and dropping funnel bottom or the medicine liquid outlet of housing bottom all is to rely on seal membrane to seal, and be once sealing, and buoyancy aid only is subjected to the effect of buoyancy and gravity in housing, buoyancy aid freely moves at housing, the position is uncertain when need seal, the required precision height at medicine liquid outlet fitted seal place of buoyancy aid and dropping funnel bottom in addition, existing manufacturing technique is difficult to reach the requirement of sealing fully, cause sealing reliability not high, safety is low; The 2nd, be a cavity between seal membrane and the concave shaped portion, liquid enters cavity easily when transfusion, and it is heavy to increase buoyancy aid, the exit passageway of medicinal liquid may occur sealing at any time or in advance, thereby cause the buoyancy aid cisco unity malfunction; The 3rd, owing to be a cavity between seal membrane and the concave shaped portion, and seal membrane is thinner, make the jag of export department of medicinal liquid pierce through diaphragm easily, cause and to seal, the 4th, above-mentioned patent and prior art all are after the medicinal liquid in housing is totally lost aspect automatic stream, realize fluid stopping inevitably causing air can enter in patient's body by buoyancy aid shutoff medicine liquid outlet passage.
The utility model content
In order to overcome above-mentioned defective of the prior art, this utility model provides a kind of automatic flow-stop transfusion device, this automatic flow-stop transfusion device, when the medicinal liquid in the housing also remaining a little the time, buoyancy aid will seal medicine liquid channel, just remaining medicinal liquid separates air, effectively prevents in the air admission patient body.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automatic flow-stop transfusion device, comprise needle for inserting bottle, infusion tube, flow regulator, dropping funnel, venoclysis needle and release mechanism, described release mechanism comprises housing and buoyancy aid, described housing comprises medicinal liquid arrival end and medicine liquid outlet end, described medicine liquid outlet end is formation link protruding upward in housing, it is characterized in that: described housing bottom connects the medicinal liquid locker room, and described buoyancy aid is positioned at the medicinal liquid locker room; Described buoyancy aid bottom is provided with a concave shaped portion, is provided with sealing cap in the described concave shaped portion; The bottom of described medicinal liquid locker room is provided with and intercepts the spacer that medicinal liquid is flowed into to the medicinal liquid locker room by housing, and top is provided with medicinal liquid and flow to netted open-end hole in the medicinal liquid locker room by housing; Radially to projecting inward formation locating part, the middle part is medicinal liquid is flowed into the medicinal liquid locker room by housing through hole around the top of medicinal liquid locker room.
Described sealing cap comprises crown and ring cap body, and an end and the crown of ring cap body are tightly connected, and the other end forms opening, and the diameter of described open end is greater than the diameter of link, buoyancy aid sinking opening and link fitted seal.
The height that described link protrudes the medicine liquid outlet end equates with the height of ring cap body.
Be provided with the location tooth bar between the sidewall of described buoyancy aid and medicinal liquid locker room.
The utlity model has following advantage:
