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 when transfusion finishes, and prevents that effectively outside air from entering the transfusion device of a kind of disposable automatic flow-stop in patient's body.
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, a transfusion device is in use as changing infusion bottle or do not have the automatic flow-stop effect when medicinal liquid being totally lost, if the nursing staff does not note slightly, air can enter in patient's body, cause some unsafe factors, nursing staff's work simultaneously causes anxiety.
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.
China Patent No. " 200320131818.4 " discloses a kind of disposable use and has ended the liquid transfusion device automatically, 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 dropping funnel lower curtate a bright and clean medicinal liquid access road, 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 conehead 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, causes sealing reliability not high; 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 utility model content
In order to overcome above-mentioned defective of the prior art, this utility model provides a kind of disposable automatic flow-stop transfusion device, and this disposable automatic flow-stop transfusion device can prevent that buoyancy aid from floating arbitrarily in housing, can reach sealing fluid stopping effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Disposable 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 top is provided with the medicinal liquid arrival end, lower housing portion is provided with the medicine liquid outlet end, described medicine liquid outlet end is formation link protruding upward in housing, described housing middle part is provided with locating part, it is characterized in that: described buoyancy aid is a sealing cap, described sealing cap comprises crown and ring cap body, described buoyancy aid is connected with housing bottom by flexible connecting member, and described crown middle part is protruded and formed boss, buoyancy aid sinking boss and link fitted seal.
Convex to form protuberance around the described ring cap body, the housing inner bottom part is provided with the annular groove that is sealed and matched mutually with protuberance.
Described protuberance is step-like, and the length of protuberance projection is consistent with the degree of depth of annular groove.
Described locating part and housing are integrally formed, and locating part is the disk sieve of being convenient to the medicinal liquid infiltration.
The utlity model has following advantage:
1, buoyancy aid described in this utility model is a sealing cap, sealing cap sealing effectiveness in seal process is better, described sealing cap comprises crown and ring cap body, described buoyancy aid is connected with housing bottom by flexible connecting member, and flexible connecting member connects, and prevents that buoyancy aid from floating in the housing optional position, the position is uncertain, accurate and the link sealing of buoyancy aid energy when transfusion finishes, the formation boss is protruded at described crown middle part, and buoyancy aid whereabouts boss and link fitted seal effect can be better.
