Abstract
The utility model relates to a transfusion apparatus self-closing device, comprising a casing. A liquid inlet and a liquid outlet are respectively arranged at upper and lower ends of the casing; a base provided with a recessed cavity is arranged inside the casing; a floating body is arranged inside the base; the external surface of the floating body is matched with the internal surface of the recessed cavity of the base; and a liquid outlet hole is arranged at the center of the base. The self-closing device has the advantages that the floating body and the recessed cavity of the base can be matched with each other so as to effectively solve the problems of medicine residue and blood return, which is caused by delayed withdrawal of needle; the structure is simple; the effect is excellent; and the utility model can be applied on other instruments with similar functions except for the medical instrument.
Description
Technical field
This utility model relates to a kind of as medical apparatus and instruments, especially relates to a kind of transfusion device self-closing device.
Background technology
Transfusion device is the very large expendable consumed product of hospital's use amount, when patient infusion, because the time is longer, the person of accompanying and attending to or patient are easy to generate feeling of fatigue, in case medicinal liquid drips off, pull out pin as the untimely nurse of notice, can make patient's blood back, cause suffering to patient, it is too early to pull out pin, residual liquor is too much, can cause waste again.The someone two ends that will have the transfusion drip tube of transfusion device now respectively add a check valve now, in order to solve the medicinal liquid residue problem, but can not solve the blood back problem simultaneously, and the structure more complicated of this transfusion device, cost height, uneconomical, the somebody will be in the transfusion device dropper increases a ball float, and ball float is reduced to the fluid mouth of pipe it is blocked when medicinal liquid drips off.Be used to address the above problem, do not have effective plugging action but experiment showed, that ball float contacts with line between the drain pipe.The inventor had once applied for a patent in 2006, application number 200620031175X is used to address these problems, but find that in practice after medicinal liquid entered inlet, impact velocity was too fast sometimes, impulsive force is big, easily ball float is swept away, and results in blockage to discharge medicinal liquid.
Summary of the invention
The purpose of this utility model just is to provide the well transfusion device self-closing device that drips smoothly of discharge opeing simultaneously of a kind of simple in structure and plugging effect.
The purpose of this utility model can realize by following measure:
This utility model comprises shell, shell offers inlet and liquid outlet respectively in two ends up and down, be provided with the base of band cavity in the enclosure, in base, be provided with buoyancy aid, the inner surface of cavity matches in the outer surface of buoyancy aid and the base, be provided with liquid outlet at the base center, around the damping fin and between the shell, and all leave the gap between damping fin bottom and the shell inlet place inwall.
Buoyancy aid is spheroid or cone etc. in this utility model, also can be other suitable shapes.Leave the gap between base and the shell.Shell and base are drum or other shapes.Shell by the cylindrical chamber at middle part and up and down the fluid-through tube at two ends constitute.Perhaps, shell is made of the cylindrical chamber at middle part and the fluid-through tube of lower end.In addition, shell is made of the two parts up and down that fit together, and certainly, also can be made into integral structure.Damping fin is made of the boss of lamellar body and lamellar body bottom, offers the invaginating groove around the lamellar body.
The design of cavity etc. in buoyancy aid that this utility model owing to adopt coincide mutually and the base makes it effectively to solve medicine residue problem and the untimely blood back problem of pulling out pin and causing, has advantages such as simple in structure, respond well.Simultaneously, the ball float that has also solved former technology is swept away the blockage problem that causes.In addition, this utility model is except that using medical apparatus and instruments, also applicable other have similar functions aspect.
Description of drawings
Accompanying drawing is cutaway view of the present utility model (structural representation).
The specific embodiment
This utility model is done with detailed description below in conjunction with drawings and Examples:
As shown in the figure, this utility model comprises shell (1), shell (1) two ends up and down offers inlet (6) and liquid outlet (7) respectively, in shell (1), be provided with the base (2) of band cavity (4), base (2) is pressed on the shell (1), be provided with buoyancy aid (3) in base (2), the inner surface of cavity matches in the outer surface of buoyancy aid (3) and the base (2), is provided with liquid outlet (5) at base (2) center.In shell (1), be positioned at the inlet place and be mounted with damping fin (8).Damping fin (8) is all around and between the shell (1), and all leaves the gap between damping fin (8) bottom and shell (1) the inlet place inwall.Damping fin (8) constitutes (certainly, boss also can be arranged on the outer casing inner wall) by the boss of lamellar body and lamellar body bottom, offers the invaginating groove around the lamellar body.Buoyancy aid (3) is spheroid or cone, or other suitable shapes.Leave the gap between base (2) and the shell (1), base (2) can fit together more easily with shell (1) like this.Shell (1) is a drum etc. with base (2)., shell (1) by the cylindrical chamber at middle part and up and down the fluid-through tube at two ends constitute.In addition, shell should be made of the two parts up and down that fit together, and like this, base can be inserted in the shell during assembling.Certainly, shell also can be made into integral structure.At this moment, shell (1) is made of the cylindrical chamber at middle part and the fluid-through tube of lower end, and base can directly be inserted by the shell upper end.
Operation principle of the present utility model is as follows: characteristics of the present utility model are that the surface of base cavity and buoyancy aid matches, and the cavity central part offers liquid outlet.During use, medicinal liquid is flowed into by device top, the buoyant device of buoyancy aid upper end, when transfusion will finish, buoyancy aid moved down gradually with liquid level in the device, in the time of in buoyancy aid drops to the base cavity, its buoyancy aid outer surface fits like a glove with low seat concave surface, base cavity center liquid outlet is blocked fully, played good plugging action, thereby can effectively solve medicine residue problem and the untimely blood back problem of pulling out pin and causing.
