Description

A portable intelligent infusion set

technical field

The invention relates to the technical field of medical instruments, in particular to an infusion set.

Background technique

At present, the infusion sets used by infusion patients mainly include traditional infusion sets and infusion pumps. Traditional infusion sets are composed of intravenous needles, protective caps, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, cork puncturers, air intake pipe air filters, and are mainly used for disposable medical treatment of intravenous infusion. consumables. The infusion pump is an instrument that can accurately control the number of infusion drops or infusion flow rate, ensure that the drug can enter the patient's body at a uniform speed, accurate and safe, and play a role, and can realize the alarm of infusion blockage, air bubble mixing and infusion completion. But above-mentioned infusion equipment mainly has the following problems:

During the infusion process, the traditional infusion set has disadvantages such as inconvenience for the infusion patient to walk around, easy return of blood, manual monitoring, and inaccurate infusion speed. The comparatively advanced infusion pump has the problem that it cannot be popularized due to its large volume and high price; the above-mentioned problems have yet to be solved.

Contents of the invention

The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology, and provide a portable intelligent infusion device, which can facilitate the activities of patients undergoing infusion, and can also help to reduce the work intensity of nurses, save manpower, and improve the safety of infusion , accuracy and work efficiency.

In order to achieve the above object, the present invention adopts the following technical solutions:

The portable intelligent infusion device is characterized in that it includes a strap, an outer box fixed on the strap, an inner box installed in the outer box, an infusion bag, an infusion tube drawn from the infusion bag, and a flow controller arranged on the infusion tube ; The inner box is provided with a single-chip microcomputer and a micro air pump connected thereto, a flow sensor, the micro air pump is connected with the inflation hole of the infusion bag through an air delivery tube, the flow sensor is arranged on the air delivery tube, and the outer box is provided with a The display screen connected to the microcontroller and the operation buttons.

Preferably, the infusion bag has a double-layer structure, including an inner liquid bag and an outer air bag wrapped around it, the inner liquid bag is connected to the infusion tube, and the outer air bag is connected to the air delivery tube.

Preferably, a card slot is formed on the strap, and the card slot is adapted to the outer box.

The beneficial effects of the present invention are: the present invention utilizes the single-chip microcomputer to control the miniature air delivery pump, so that the air delivery pump exerts pressure on the outer layer of the infusion bag, and gets rid of the restriction of the gravitational potential energy of the traditional infusion set during the infusion process, which makes it inconvenient for the infusion patient to move around and requires manual monitoring. Disadvantages; at the same time, the present invention utilizes the flow sensor and the flow controller to improve the accuracy of infusion regulation, the safety of the infusion process, and reduce the working pressure of medical staff.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following examples.

As shown in Figures 1 to 5, the portable intelligent infusion set provided by the present invention includes a strap 14, an outer box fixed on the strap, an inner box installed in the outer box, a black box and an infusion bag, and an infusion solution drawn from the infusion bag. Tube and the flow controller 16 arranged on the infusion tube.

The outer box is formed by connecting the upper box body 1 and the lower box body through the rotating shaft 5 on the rear side of the lower box body, and the switch button 6 on the front side of the lower box body controls the opening and closing of the upper box body. The inner box 8 is fixed on the rear side of the inner cavity of the lower box body 7 through the clamping structure 18 of the lower box body and the buffer cotton 10, and the infusion bag is placed on the front side of the inner cavity of the lower box body. The black box is installed in the inner box, and the buffer cotton 10 and the buffer cotton 11 (the front side of the infusion bag) effectively protect the stability of the black box 9 and the infusion bag 12-2.

Described black box is provided with power supply, single-chip microcomputer and the miniature air pump that is connected with single-chip microcomputer, flow sensor 13. The micro air pump is connected to the inflation hole of the infusion bag through the air delivery pipe 3, and the flow sensor is arranged on the air delivery pipe. The outer box is provided with a display screen 4 and operation buttons 17 connected with the single-chip microcomputer.

The infusion bag has a double-layer structure, including an inner liquid bag 12 and an outer air bag 2 wrapped outside it. The inner liquid bag is connected with the infusion tube, and the outer air bag is connected with the air delivery tube. Through the effect of the miniature air pump 9, the infusion bag 12-2 is pressurized, and the pressure in the outer layer air bag 2 constantly increases. When the pressure in the outer layer air bag 2 is greater than the external atmospheric pressure, the liquid in the inner layer liquid bag 12 will Flow out from the infusion tube, the operation button 17 and the flow controller 16 can adjust the dripping speed and the liquid flow rate very accurately.

The upper side of the strap is a rubber belt, and a rubber slot is formed on the rubber strap, which is compatible with the outer box. The rubber material can increase the friction, so that the connection between the box body and the strap is more firm. The lower layer of the strap is made of medical elastic cloth, which can increase the comfort of the infusion user. The two ends of the strap can be fixed on the arm of the infusion user through Velcro (hook and loop).

When the present invention is in use, at first the nursing staff can open the upper box body 1 by the switch button 6, and the air delivery hole of the outer layer air bag 2 of the transfusion bag 12-2 is connected with the air delivery tube 3, and the bottle stopper of the inner layer liquid bag 12 is connected with the air delivery tube 3. The infusion tube is connected; the infusion bag can be fixed in the lower box body 7 through the suspension ring 15. After the above actions are completed, the box bodies 1 and 7 can be closed by the switch button 6; the nursing staff needs to fix the strap 14 on the arm of the infusion patient, and then The whole outer box is fixed in the draw-in slot on the bandage 14; the transfusion person can turn on the power by operating the button 17 at this moment, and adjust the dripping liquid speed and flow according to the data shown on the display screen 4; when the transfusion is about to end, the flow controller 16 (Prior art) It can be automatically connected to the nurse's desk for alarm.

Finally, it should be noted that the present invention is not limited to the above embodiments, and many variations are possible. All deformations that can be directly derived or associated by those skilled in the art from the content disclosed in the present invention should be considered as the protection scope of the present invention.
