Abstract
The utility model provides a disposable safe transfusion device which is used for venous transfusion in the field of medical sanitation. The transfusion device is composed of the following components: a bottle insertion needle, a flexible pipe, a flow regulator, a soup filter, a venous transfusion needle, a dropping funnel and a safe mechanism; wherein the safe mechanism comprises the following components: an annular upper sealing gasket and an annular lower sealing gasket which are directly provided at the bottom of the dropping funnel, and a ball float which is provided between two sealing gaskets and can seal a through hole between the annular upper sealing gasket and the annular lower sealing gasket. In a use process, obstruction is prevented by means of floating of the ball float in a soup conveying process. When the transfusion is finished, the ball float drops along the liquid level of the soup to the plane of the annular sealing gasket thereby closing the transfusion channel, so the air can not enter thereby realizing safe transfusion.
Description
Technical field
This utility model relates in a kind of medicine and hygiene fields the infusion set of using when carrying out the vein fluid injection to clinical patients; More particularly; Relate to and a kind ofly when the vein fluid injection, can seal infusion pipeline automatically, prevent the intravital disposable transfusion device safe in utilization of air admission patient.
Background technology
When at present the patient being carried out venous transfusion, the disposable transfusion device that is widely used is like this to preventing that the cross infection between the patient from having played positive role.But; Use disposable transfusion device also to have weak point; Be that present disposable transfusion device does not have automatic sealing process when medicinal liquid has been annotated, do not note slightly at this moment, will make in the air admission patient's vein as if the nursing staff; And these air admission can bring the factor that is absolutely unsafe to the patient behind vein, also give originally simultaneously and bring more nervous work with regard to the nursing staff with big workload.
The utility model content
The technical problem that this utility model will solve is to provide a kind of can automatically seal infusion pipeline in transfusion when finishing nearly, to avoid the intravital disposable safe transfusion system of air admission patient.
In order to address the above problem; The disposable safe transfusion system that this utility model provides; Comprise needle for inserting bottle, dropping funnel, flexible pipe, liquid medicine filter and venoclysis needle that perforation successively is tightly connected; Said hose overcoat has flow controller; In the said dropping funnel or the outer flexible pipe of said dropping funnel be provided with and avoid that air gets into the intravital release mechanism of patient through flexible pipe when transfusion finishes, said release mechanism comprises a housing, upper and lowerly respectively be arranged on sealing gasket and ring-type lower seal pad on the intravital ring-type of shell, be located on the said ring-type between the sealing gasket and ring-type lower seal pad and the ball float that can freely rotate.
Preferably, said housing is the part of said dropping funnel.
Preferably, said housing is the latter half of said dropping funnel.
Preferably, said housing is a separate component, and the top of said housing and bottom are respectively equipped with the entrance and exit that can be tightly connected with flexible pipe.
Preferably, sealing gasket and ring-type lower seal pad are fixed in the said housing through glued or integrated mode on the said ring-type.
Disposable safe transfusion system in this utility model; Need not patient and the nursing staff pay close attention to the end of transfusion; When treating that transfusion finishes; Disposable safe transfusion system can seal infusion pipeline automatically by means of the ball float in the release mechanism, prevents that air bubble from getting into patient's vein, alleviated medical worker's tense working simultaneously significantly.
Description of drawings
Fig. 1 is the structural representation of this utility model transfusion device.
Fig. 2 is the structural representation of another embodiment of this utility model transfusion device.
The specific embodiment
Further specify below in conjunction with the scheme of accompanying drawing this utility model.
As shown in Figure 1; A kind of disposable safe transfusion system of this utility model; Comprise needle for inserting bottle 1, dropping funnel 2, flexible pipe 3, liquid medicine filter 5 and venoclysis needle 6 that perforation successively is tightly connected; Hose overcoat has flow controller 4, is prior art for the concrete structure and the operation principle of this disposable transfusion device, no longer specifies at this.
As shown in Figure 1; The principal character of the disposable transfusion device safe in utilization in this utility model is that the inner bottom part at dropping funnel 2 is arranged with sealing gasket 70 and ring-type lower seal pad 71 on the ring-type up and down in parallel; And between sealing gasket 70 on this ring-type and ring-type lower seal pad 71, be provided with a ball float 72; Wherein thin around the middle ratio of sealing gasket 70 and ring-type lower seal pad 71 on the ring-type, and a plane is arranged, and the centre is a through hole; Sealing gasket 70 is processed by soft and the elastic material of tool with ring-type lower seal pad 71 on this ring-type, and this material should meet hygienic requirements simultaneously.Distance on the ring-type between sealing gasket 70 and the ring-type lower seal pad 71 should be greater than 30% of ball float 72 diameters; Guarantee freely to rotate in the cavity that ball float 72 sealing gasket 70 and ring-type lower seal pad 71 on by ring-type constitute, and sealing gasket 70 and ring-type lower seal pad 71 can be fixed on the inner bottom part of dropping funnel 2 through gluing or integrated mode on this ring-type.Transfusion device in this utility model is directly arranged in by two that sealing gasket 70 constitutes liquid level control release mechanism with ring-type lower seal pad 71 and ball float 72 on the ring-type of dropping funnel 2 inner bottom parts; Utilize this liquid level control release mechanism can effectively prevent when transfusion finishes nearly; In the air admission patient body, cause danger.
As shown in Figure 1, during disposable safe transfusion system in using this utility model, at first needle for inserting bottle 1 is inserted infusion bottle plug or transfusion bag; Be the come-up state in the cavity that ball float 72 in the liquid level control release mechanism sealing gasket 70 and ring-type lower seal pad 71 on by ring-type are constituted, sealing gasket 70 on the closed circular, when following of the medicinal liquid in the infusion bottle; Ball float 72 is along with the liquid level of medicinal liquid descends and descends; Drop on until ball float 72 on the plane of ring-type lower seal pad 71, by means of the through hole sealing of the gravity of ball float 72 and ball face with sealing gasket on the ring-type 71, with air barrier in dropping funnel 2; And can't enter in the flexible pipe 3, thereby guarantee the safety of infusing.
As shown in Figure 2, another embodiment of disposable safe transfusion system in this utility model, in this embodiment; Liquid level control release mechanism and dropping funnel were opened in 2 minutes, became a separate component, i.e. liquid level control release mechanism includes a housing 73; This housing 73 above that, down two ends are respectively arranged with inlet 74, the outlet 75 that can be tightly connected with flexible pipe 3 and 8, promptly be communicated with dropping funnel 2 through flexible pipe 8 in the upper end, and the lower end is communicated with flexible pipe 3; Identical as among other structures and the embodiment one; Explain no longer separately at this, therefore, utilize this transfusion device can realize the purpose of safe infusion equally.
In sum, the disposable safe transfusion system in this utility model in use need not patient and the nursing staff pay close attention to the end of transfusion, just can prevent effectively that air bubble from getting into patient's vein, alleviated medical worker's tense working simultaneously significantly.
More than just this utility model has been carried out exemplary explanation, the concrete implementation of this utility model is not limited thereto.The insubstantial modifications that design of any employing this utility model and technical scheme are carried out is all within the protection domain of this utility model.
