Abstract
The utility model discloses a dropper mechanism of an automatic stop liquid transfusion device. The dropper mechanism comprises a dropper body. The dropper body comprises two parts of an upper cavity and a lower cavity. A distance plate is arranged between the upper cavity and the lower cavity and separates the upper cavity and the lower cavity. A communicating pipe is arranged in the middle of the distance plate and penetrates through the upper cavity and the lower cavity. A dropping liquid siphunculus communicated with the dropper and a transfusion hosepipe is arranged at the top portion of the upper cavity of the dropper. A venting catheter communicated with the dropper and the transfusion hosepipe is arranged at the bottom portion of the lower cavity. A columnar buoy is arranged inside the upper cavity. A membrane is arranged in the corresponding position of the buoy and the venting catheter. The diameter of the membrane is larger than that of the communicating pipe. The dropper mechanism of the automatic stop liquid transfusion device is exquisite in structure, capable of stopping liquid when no one is present, and thereby the accident of blood return is efficiently avoided. Due to the installation of an air filter, not only can the problem of the gravity of the medicine liquid be solved, but also tiny dust in the air can be prevented from dropping into the dropper.
Description
Technical field
This utility model relates to an a kind of kettle mechanism of transfusion device, is specially an a kind of kettle mechanism of automatic liquid-stopping transfusion apparatus, belongs to technical field of medical instruments.
Background technology
Transfusion device is one of hospital's medical apparatus and instruments commonly used, is mainly used in the gravity type venous transfusion.Generally be to be connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle assembly, bottle plug puncture unit, air inlet pipe air filter.Under atmospheric effect, the liquid runs down infusion tube flows into and drips kettle in the bottle, and when dripping the kettle water column pressure greater than venous pressure, the liquid runs down flexible pipe in the bottle flows into passages through which vital energy circulates.
Drip kettle mechanism and generally be comprised of two parts chamber up and down, middlely separate with the backstop grid, the top of dripping part on the kettle is infusion connector, is communicated with infusion bottle by infusion tube, bottle plug puncture unit; The bottom of dripping part cavity under the kettle also is provided with infusion connector, is communicated with the passages through which vital energy circulates of human body by infusion tube, passages through which vital energy circulates pin.There are some defectives in this kettle mechanism: 1, a traditional kettle drips and weighs not, causes dropping liquid slower, is difficult for regulating; 2, generally in long infusion process, may the unmanned state, when medicinal liquid dripped off soon, the air pressure in the infusion set was lower, in the time of may causing the medicinal liquid deadweight less than vein blood vessel pressure, the accident of blood backflow.3, drip the kettle bottom because the infusion connector of traditional lower part cavity will be higher than in dripping kettle, so medicinal liquid has in dripping kettle residually, can not drain.
The utility model content
The purpose of this utility model is for an a kind of kettle mechanism of automatic liquid-stopping transfusion apparatus is provided, to solve existing the problems referred to above of dripping kettle.
The purpose of this utility model can be achieved through the following technical solutions:
An a kind of kettle mechanism of automatic liquid-stopping transfusion apparatus comprises and drips a kettle main body that described kettle main body comprises upper and lower cavity two parts, separated by dividing plate in the middle of the upper and lower cavity, and the centre of dividing plate is provided with runs through upper cavity and lower chamber communicating pipe; The upper cavity top of dripping kettle is provided with the dropping liquid siphunculus and is communicated with droplet kettle and an infusion tube, and the bottom of lower chamber is provided with the aerofluxus catheter and is communicated with droplet kettle and an infusion tube; One column buoy is set in the described upper cavity, and the buoy position corresponding with aerofluxus drain siphunculus is provided with barrier film, and the diameter of barrier film is greater than the diameter of communicating pipe.
Drip the heavy deficiency of dripping of kettle in order to solve, lower slow-footed problem of medicinal liquid is provided with an air filter with air film at the lower chamber sidewall that drips kettle.
In order to guarantee the health of air film, also dispose safety head at air filter, open during use.
It is inlet that the partial sidewall of described aerofluxus catheter in dripping kettle is provided with some vertically evenly distributed finedraws; The lower end of described inlet is concordant with the inwall that drips the kettle bottom.
Bonding by viscose between the described upper and lower cavity of kettle.
The outer wall of described buoy is dentalation, so that medicinal liquid passes through.
The transfusion device that forms by this utility model setting drips the kettle assembly, and delicate structure can be in unattended situation, automatic liquid-stopping, and the accident of effectively anti-return blood occurs.And the setting of air filter both can solve and drip the heavy problem of kettle Chinese medicine drop, can prevent that again airborne micronic dust from entering a kettle.
Description of drawings
Fig. 1 is the structural representation (dividing plate and buoy partly are sectional structure) that this utility model drips the kettle assembly;
Among the figure: 1, upper cavity 2, lower chamber 3, dropping liquid communicating pipe 4, aerofluxus catheter 5, air filter 6, buoy 7, barrier film 8, dividing plate 9, communicating pipe 10, inlet.
The specific embodiment
Further set forth construction features of the present utility model below in conjunction with accompanying drawing and specific embodiment.
A kettle mechanism of a kind of automatic liquid-stopping transfusion apparatus as shown in Figure 1, comprise and drip the kettle main body, described kettle main body comprises upper cavity 1 and lower chamber 2 two parts, separated by dividing plate 8 in the middle of upper cavity 1 and the lower chamber 2, and the centre of dividing plate 8 is provided with runs through upper cavity 1 and lower chamber 2 communicating pipe 9; Upper cavity 1 top of dripping kettle is provided with dropping liquid siphunculus 3 and is communicated with droplet kettle and an infusion tube, and the bottom of lower chamber 2 is provided with aerofluxus catheter 4 and is communicated with droplet kettle and infusion tubes; The described upper cavity 1 interior column buoy 6 that arranges, buoy 6 and communicating pipe, 9 corresponding positions were provided with barrier film 7, and the diameter of barrier film 7 is greater than the diameter of communicating pipe 9.
To drip dripping of kettle heavy not enough in order to solve, and lower slow-footed problem of medicinal liquid is provided with an air filter 5 with air film at the sidewall of the lower chamber 2 of a kettle.
In order to guarantee the health of air film, also dispose safety head at air filter 5, open during use.
It is inlet 10 that the partial sidewall of described aerofluxus catheter 4 in dripping kettle is provided with some vertically evenly distributed finedraws; The lower end of described inlet 10 is concordant with the inwall that drips the kettle bottom.
Bonding by viscose between described kettle upper cavity 1 and the lower chamber 2.
The outer wall of described buoy 6 is dentalation, so that medicinal liquid passes through.
When beginning to infuse, medicinal liquid rises in the fluid level of upper cavity 1, until buoy 6 places, buoy 6 beginnings are at the effect float downward of buoyancy; When fluid level continuation rising was higher than the height of the communicating pipe 9 in the upper cavity 1, buoy 6 was opened fully, and medicinal liquid enters lower chamber 2 by communicating pipe 9.
