Abstract
The utility model discloses a kind of disposable transfusion device.It comprises a long tube for transfusion and a thin short tube for transfusion, long tube for transfusion is provided with successively bottle plug puncture unit, drips kettle, transfuse switch, liquid medicine filter; Thin short tube for transfusion front end is connected with liquid medicine filter by exhaust joint, and thin short tube for transfusion end is connected with venoclysis needle; Described exhaust joint is swivel joint, and the connection namely between the end of liquid medicine filter and thin short tube for transfusion front end adopts the mode that spins.Disposable transfusion device of the present utility model, exhaust joint is designed to the mode of being rotatably connected, can makes better more firmly to be connected between liquid medicine filter and the thin short tube for transfusion before venoclysis needle, simultaneously, convenient disassembly, needs also can take apart to be easily exhausted when taking aerofluxus apart.In addition, do not increase how many costs, have larger application and popularization value.
Description
Technical field
This utility model belongs to medical apparatus technical field, relates to a kind of disposable transfusion device of clinical transfusion.
Background technology
The use of disposable transfusion device, brings facility for needing the patient of intravenously administrable.Transfusion device conventional is clinically plastic, its from top to bottom general by bottle plug puncture unit, tube for transfusion, drip kettle, transfuse switch, liquid medicine filter, exhaust joint and a venoclysis needle and form.In Clinical practice process, its advantage is a lot, and Be very effective, be subject to doctor and patient favorable comment, but it still exists certain defect.Venting is needed to enter the gas of tube for transfusion during transfusion, traditional method for exhausting is: first make to drip in kettle and rush in a certain amount of medicinal liquid, then the exhaust joint be located at after liquid medicine filter dismounting is come, open transfuse switch, draining a part of medicinal liquid from exhaust joint could outside the gas outlet pipe in tube for transfusion.The method of attachment of existing exhaust joint is generally directly be socketed to form by the front end of the tube for transfusion latter end of upper end and liquid medicine filter end and lower end and connecting intravenous infusion pin; this socketing method very built on the sand; often can there is exhaust joint to get loose the phenomenon come; cause the waste of quite a few medicinal liquid, cause certain economic loss.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can firmly connect and the disposable transfusion device of convenient disassembly.
The technical solution of the utility model is as follows:
A kind of disposable transfusion device, it comprises a long tube for transfusion and a thin short tube for transfusion, long tube for transfusion is provided with successively bottle plug puncture unit, drips kettle, transfuse switch, liquid medicine filter; Thin short tube for transfusion front end is connected with liquid medicine filter by exhaust joint, and thin short tube for transfusion end is connected with venoclysis needle; Described exhaust joint is swivel joint, and the connection namely between the upper end (i.e. the end of liquid medicine filter) of exhaust joint and lower end (i.e. the front end of the thin short tube for transfusion of connecting intravenous infusion pin) adopts the mode that spins.
Further, described swivel joint is that internal and external threads is rotatably connected mode.
Further, the connected mode of described swivel joint is: on the inwall of coupling, establish L-shaped groove, and the outer wall of nipple arranges the projection in the groove that can insert in coupling.During use, inserted by nipple in coupling, the projection on nipple inserts in the groove in coupling, rotates to an angle, namely projection on nipple arrives the right angle turn of vertical line trench bottom along the vertical line groove of L-shaped, then embed in the bottom transverse wire casing of L-shaped and namely fix.When needing to take aerofluxus apart, as long as the projection on nipple to be released the bottom transverse wire casing of the L-shaped in coupling, after arriving the right angle turn of L-shaped, rotate to an angle, the vertical line groove along L-shaped withdraws.
Further, described swivel joint place (i.e. the end of liquid medicine filter and the front end of thin short tube for transfusion) can be cylindrical shape or taper shape.
The beneficial effects of the utility model:
Disposable transfusion device of the present utility model, exhaust joint is designed to the mode of being rotatably connected, can makes better more firmly to be connected between liquid medicine filter and the thin short tube for transfusion before venoclysis needle, simultaneously, convenient disassembly, needs also can take apart to be easily exhausted when taking aerofluxus apart.In addition, do not increase how many costs, have larger application and popularization value.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As shown in Figure 1, a kind of disposable transfusion device of this utility model, it comprises long tube for transfusion 1 and a thin short tube for transfusion 2, long tube for transfusion is provided with successively bottle plug puncture unit 3, drips kettle 4, transfuse switch 5, liquid medicine filter 6; Thin short tube for transfusion 2 front end is connected with liquid medicine filter 6 by exhaust joint 7, and thin short tube for transfusion 2 end is connected with venoclysis needle 8; Described exhaust joint is swivel joint, and the connection namely between the upper end (i.e. the end of liquid medicine filter) of exhaust joint and lower end (i.e. the front end of the thin short tube for transfusion of connecting intravenous infusion pin) adopts the mode that spins.
As shown in Figure 2, the connected mode of described swivel joint is: on the inwall of coupling, establish L-shaped groove 9, and the outer wall of nipple is provided with a small lugs in the groove that can insert in coupling.During use, inserted by nipple in coupling, the small lugs on nipple inserts in the groove in coupling, rotates to an angle, namely small lugs on nipple arrives the right angle turn of vertical line trench bottom along the vertical line groove of L-shaped, then embed in the bottom transverse wire casing of L-shaped and namely fix.When needing to take aerofluxus apart, as long as the small lugs on nipple to be released the bottom transverse wire casing of the L-shaped in coupling, after arriving the right angle turn of L-shaped, rotate to an angle, the vertical line groove along L-shaped withdraws.
(i.e. exhaust joint 7 place of described swivel joint place, the end of liquid medicine filter and the front end of thin short tube for transfusion) can be cylindrical shape or taper shape, the end of exhaust joint 7 place liquid medicine filter and the front end of thin short tube for transfusion are conical as shown in fig. 1, and the end of exhaust joint 7 place liquid medicine filter and the front end of thin short tube for transfusion are cylindrical shapes as shown in Figure 2.
Disposable transfusion device of the present utility model is plastic, and the inwall of coupling is offered L-shaped groove, and on the outer wall of nipple, arranging a small lugs, and all very convenient being easy to just can be accomplished, and does not increase how many costs.Therefore, this utility model has larger application and popularization value.
