Description

Multifunctional automatic intravenous injection device

Technical Field

The utility model belongs to the technical field of medical appliances, especially, relate to a multi-functional automatic intravenous route device.

Background

The currently common venous transfusion device consists of a breather pipe and a transfusion pipe. The air pipe connects the bottle with the atmosphere, and the transfusion tube comprises a needle, a hose, a dropper, a regulator, a filter, etc. The device is simple, efficient and low in cost, but has some defects. 1) Air bubbles are easily mixed in the liquid medicine in the needle tube. Air which can be dissolved by human blood under normal conditions is extremely limited, and if a large amount of air rapidly enters the blood circulation of a human body in a short time, air embolism can be caused, blood vessels can be blocked, and even the heart can stop beating or acute respiratory circulation failure can be caused; 2) the filtering degree of the insoluble particles of the needle tube liquid medicine is low. The diameter of the smallest capillary vessel of the human body is only 4-7 microns. Insoluble particles with particle size of more than 4 μm in the injection enter blood circulation, and are easy to block capillary vessels, so as to cause pulmonary granuloma, pulmonary edema, phlebitis, anaphylaxis and the like, and drug-induced renal injury, lung cancer, leukemia and the like; 3) the dripping speed is not controllable. For different situations of each patient, such as medicines used during transfusion, doctors will specially order nurses to adjust the corresponding transfusion speed for the patients. However, the nurse usually adjusts the drip speed manually based on his own experience, and there is a considerable error in the drip speed required for the medication instruction. In addition, many patients always feel that the infusion speed is too slow or too fast and is adjusted privately, and the treatment effect is influenced and meanwhile some clinical hazards are brought, such as the burden of the heart of a human body is increased and drug poisoning is caused; 4) the automation and intelligence degree is low. Along with the acceleration of the rhythm of life and the aggravation of the aging degree of population, the old and children usually need adults to accompany and constantly monitor the transfusion state when carrying out infusion, and meanwhile, nurses also need to constantly patrol the transfusion condition of patients, so that disorder of the transfusion places is easily caused, and unnecessary manpower and material resources are wasted. There is a need for a device that can automatically monitor the status of the infusion and feed it back to the nurse.

Therefore, it is desirable to develop a multifunctional automatic intravenous infusion device to improve safety and convenience of intravenous infusion.

Detailed Description

As shown in figure 1, the multifunctional automatic intravenous infusion device comprises a controller 1, a rubber tube clamp 2 and a disposable rubber tube 3. Wherein the controller 1 is integrally connected with the dropper clamp 2. Wherein the controller 1 controls the action of the dropper clamping device 2 through an internal closed-loop control circuit. Wherein the disposable rubber tube 3 is clamped on the dropper clamp 2.

The controller 1 is shown in fig. 2 and is composed of an input panel 1-1 and a controller case 1-2. The input panel 11 is composed of a key part 1-1-1 and a display screen 1-1-2 and is used for controlling the input and display of information. Wherein the control cabinet 1-2 is internally provided with a control circuit for controlling the transfusion action. The main design idea of the controller 1 is as follows: the nurse inputs the drip speed v ml/h, nurse's patrol interval t minutes through panel 1-1. In each patrol time, the key part 1-1-1 is in a locked state, and the infusion speed cannot be changed. When the patrol time interval is reached, the control case 1-2 sends an instruction to enable the rubber tube clamp 2 to control the dropping speed to be 0 ml/h, and meanwhile, the controller 1 sends a lifting call sound to a receiving device of a nurse station to remind a nurse of checking the infusion state in the future. After the nurse checks the infusion state, the nurse inputs an instruction to unlock the key part 1-1-1 and resumes the infusion until the next time interval.

The rubber tube clamp 2 is shown in figure 3 and comprises a liquid tube clamp 2-1, an infrared flow detector 2-2, a dropper clamp 2-3, an oscillator 2-4 and a clamp shell 2-5. The main body design idea of the rubber tube clamp 2 is as follows: a dropper 3-1 of a disposable rubber tube 3 is fixed on a clamp device shell 2-5 through a dropper clamp device 2-3, and a liquid tube 3-2 at the upper part is fixed by a liquid tube clamp device 2-1. Because the pressure of gas and liquid is different, when bubbles exist in the dropper 3-1, the dropper clamping device 2-3 can judge the volume of the bubbles according to the pressure change. The clamp device shell 2-5 is provided with an infrared flow detector 2-2, and the volume of liquid flowing through within a certain time can be obtained by utilizing infrared emission and reception and a blocking signal of liquid drops. In the working process, an input panel 1-1 inputs a dropping speed control instruction, a liquid pipe clamping device 2-1 executes liquid pipe clamping action, and an infrared flow detector 2-2 is used for continuously detecting the real-time dropping speed until the required dropping speed is achieved. When the patrol interval is reached, the tube gripper 2-1 is directly actuated to maximum gripping displacement, bringing the dropping speed to 0 ml/h. When the dropper clamping device 2-3 detects that bubbles exist in the dropper 3-1 through pressure change, the vibrator 2-4 positioned at the rear part of the dropper clamping device 2-3 vibrates at a variable frequency, and liquid is disturbed so as to drive the bubbles to float upwards. When the pressure change detected by the dropper clamp 2-3 is less than the threshold value, the vibrator 2-4 stops moving.

The disposable rubber tube 3 is shown in figure 4 and consists of a dropper 3-1, a liquid tube 3-2 and a porous adsorption material 3-3. Wherein the main body design idea of the disposable rubber tube 3 is as follows: the porous adsorption material 3-3 adsorbs insoluble microparticles in the drug liquid, thereby realizing the function of filtering the microparticles.

The liquid pipe clamp 2-1 is shown in fig. 5 and comprises a liquid pipe clamp block 2-1-1 and a miniature electric telescopic rod 2-1-2. The telescopic rod of the miniature electric telescopic rod 2-1-2 penetrates through the through hole in the liquid pipe clamping block 2-1-1 to abut against the liquid pipe 3-2 of the disposable rubber pipe 3, and the miniature electric telescopic rod 2-1-2 can stretch according to a dropping speed instruction to adjust the tightness degree of the liquid pipe 3-2 placed in the middle of the groove of the liquid pipe clamping block 2-1-1 so as to control the flow speed.

A control schematic of a multi-function automatic iv set is shown in fig. 6. Wherein the input panel 1-1 inputs the drip speed and the patrol time interval instruction to the control cabinet 1-2. The flow rate of the liquid clamping tube 3-2 is controlled by controlling the displacement of the miniature electric telescopic rod 2-1-2 by the control cabinet 1-2. The infrared flow velocity detector 2-2 feeds back the detected number of the liquid drops to the control cabinet 1-2 to obtain the liquid drop flow information. The dropper clamping device 2-3 is made of piezoelectric materials, and pressure information is fed back to the control cabinet 1-2, so that the volume of bubbles in the dropper 3-1 is obtained. The control cabinet 1-2 vibrates to remove air bubbles in the dropper 3-1 by controlling the oscillator 2-4. The control module of the control cabinet 1-2 selects Siemens PLC 7-300 programmable logic controllers and configures an analog quantity module; the miniature electric telescopic rod 2-1-2 selects a CHUO SEIKI AMH13 precision miniature DC electric push rod; the main module of the infrared flow detector 2-2 is a Keli QL1516 photoelectric counting sensor; the dropper clamping device 2-3 mainly comprises an FSR flexform film pressure sensor module; the main module of the oscillator 2-4 is an Olympic robot vibration motor module, which has similar vibration effect with a mobile phone.

As shown in figure 3, the clamp shell 2-5 is provided with a mounting groove 2-5-1 for mounting the disposable rubber tube 3, and the liquid tube clamp 2-1, the infrared flow detector 2-2, the dropper clamp 2-3 and the oscillator 2-4 are all arranged in the mounting groove 2-5-1.
