Abstract

The utility model discloses an infusion apparatus, which comprises an infusion bottle and an infusion apparatus body inserted into the infusion bottle, wherein a drip cup and a flow control valve are arranged on the hose of the infusion apparatus body. The infusion apparatus also comprises a dripping speed sensor and a single-chip microcomputer. The dripping speed sensor is used for detecting the dripping speed of the drip cup and sending the detected information to the single-chip microcomputer, and the single-chip microcomputer receives the information and controls the flow control valve according to the comparison result of the information and a preset value. During use, the infusion speed can be controlled according to the need of a patient; and aiming at the two phenomena of needle running and no dropping liquid during infusion, a closing-valve action is executed, and the safety of the infusion process is ensured.

Description

A kind of transfusion device

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of transfusion device.

Background technology

At present, transfusion is the conventional means in the medical treatment, and the used transfusion device of infusing adopts packed form or bottled form mostly.Yet when medical personnel give patient infusion, first, in the insertion venous patient with venipuncture needle, the position height of its insertion is limited by the height and position of infusion bottle, in case highly be higher than the infusion bottle height, can't infuse.The second, in the infusion process, after occurring running under the situation of pin or dropping liquid end, need reminding medical personnel by patient self, handled by medical personnel, under the situation that medical personnel do not have in time to handle or patient fails to remind, the phenomenon of blood back or waste liquid medicine might appear.

The utility model content

The purpose of this utility model is the defective that exists at above-mentioned prior art, proposes a kind of transfusion device.

The technical solution adopted in the utility model is, design a kind of transfusion device, comprise: the transfusion device of infusion bottle, insertion infusion bottle, the flexible pipe of described transfusion device is provided with and drips kettle and flow control valve, also comprise one for detection of the single-chip microcomputer that drips fast induction apparatus and receive the described detected information of fast induction apparatus and according to the comparison result of this information and preset value flow control valve is controlled that drips speed that drips kettle.

In one embodiment, described fast induction apparatus is connected on the described kettle.

Described flow control valve comprises a U-shaped bayonet socket, and a side of this bayonet socket is movable slide block; The guiding slide rail that cooperates with described slide block; With the drive motors that is fixed in the control valve, this drive motors adopts screw thread output shaft to cooperate with hold-down nut on the described slide block, and described drive motors is electrically connected by described single-chip microcomputer.

Be provided with an air pressure induction apparatus between described check-valves and the air pump, described air pump is connected with this induction apparatus, the air inlet pressure of control transfusion device.

Compared with prior art, the fast induction apparatus that drips that this utility model adopts is transferred to single-chip microcomputer with liquid droping speed, single-chip microcomputer is analyzed processing to the preset value of transfusion speed, thereby precisely controlled transfusion speed by the control flow control valve, air pump on connection and the admission line has guaranteed the stable air pressure in the infusion process, total is easy for installation, and is simple in structure.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples utility model is described in detail.

As shown in Figure 1, the transfusion device that the utility model proposes, comprise: the transfusion device 2 on infusion bottle 1 and the insertion infusion bottle, transfusion device is followed successively by and connects bottle plug puncture unit, tube for transfusion, droplet kettle 4, filter and the venipuncture needle that connects, and be connected with air pump 8 with check-valves 7 by interface 6 from the air inlet pipe of the extended admission line in bottle plug puncture unit bottom, transfusion device 2, an air pressure induction apparatus 9 is installed between check-valves 7 and the air pump 8.Transfusion device further comprise successively be electrically connected drip fast induction apparatus 3, single-chip microcomputer 10 and flow control valve 5, drip fast induction apparatus 3 be U-shaped and be sheathed on drip kettle top, flow control valve 5 is installed on the tube for transfusion that drips the kettle lower end.

Dripping fast induction apparatus 3 adopts correspondence to be arranged on kettle 4 a both sides correlation LED infrared tube, infrared tube is made of infrared transmitting tube and infrared receiving tube, but also be provided with the master control borad that amplifying circuit constitutes, the logic control program and the power driving circuit that cooperate editor with singlechip chip that arrange in it, thus a complete fast induction control system formed.

Flow control valve 5 comprises a U-shaped bayonet socket, one side of this bayonet socket is movable slide block, and slide block is provided with the guiding slide rail of coupling, and slide block is provided with hold-down nut, the screw thread output shaft of the drive motors that nut is interior with being fixed on control valve cooperates, and drives moving forward and backward of slide block by drive motors.

When the medical worker uses transfusion device to give patient infusion, air pump 8 is constantly qi of chong channel ascending adversely in the infusion bottle 1, needed air pressure dynamics when keeping normal infusion, and the transfusion air pressure that detects according to air pressure induction apparatus 9, corresponding adjustment gas transmission dynamics, keep the constant transfusion air pressure in the infusion bottle 1, overcome in infusion process, the phenomenon that can't infuse when patient location is higher than infusion bottle 1 position.

After the transfusion beginning, dripping drops in the kettle 4 whenever drops and once just stops the infrared ray of an infrared tube, amplifying circuit will be carried potential pulse to single-chip microcomputer, and carry out logical calculated at single-chip microcomputer, repeatedly add up, then can calculate drop off time, single-chip microcomputer 10 should off time information and preset value contrast in real time, then the information translation of error is become the signal of telecommunication, when drip speed and set drip fast error 20 percent time, will send instruction to the drive motors in the flow control valve 5 proofreaies and correct, control drive motors output shaft rotates forward or backwards, thereby move forward and backward slide block, control the valve port size of U-shaped bayonet socket, so control tube for transfusion in infusion flow.

In this utility model; transfusion device also arranges the execution action of relevant valve at two kinds of phenomenons of " no dropping liquid " and " race pin "; when single-chip microcomputer 10 receives 6 drop dampening informations off time continuously; will be identified as and run the needle-like attitude; just carry out subsequently and close valve events, thereby reached race pin guard mode.

When the drop in the infusion bottle 1 drips off, drip kettle 4 interior no dropping liquids and fall, single-chip microcomputer 10 calculates with the drop that dripped fast induction apparatus 3 last time off time, delays 10 seconds single-chip microcomputers 10 and will carry out the pass valve events to flow control valve 5, thereby reached no dropping liquid guard mode.

Above-described embodiment only is used for the explanation specific embodiment of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from this utility model design, can also make some distortion and variation, these distortion and variation all should belong to protection domain of the present utility model.
