Description

Venous transfusion device

Technical Field

The utility model relates to a medical instrument, concretely relates to venous transfusion device.

Background

The existing disposable transfusion system is generally composed of a vein needle, a protective cap, a transfusion hose, a filter, a flow rate regulator, a drip cup and a bottle stopper puncture outfit which are connected. When the infusion apparatus is used clinically, the patient can pull the infusion apparatus to different degrees in the moving process, so that the bottle stopper puncture outfit and the infusion bottle are not stably matched, the bottle stopper puncture outfit falls off from the infusion bottle, if the bottle stopper puncture outfit falls on the ground, the patient can be subjected to secondary puncture pain caused by the replacement of the infusion apparatus, and the workload of medical staff is increased.

In addition, the filter in the existing disposable transfusion device is often to filter out the impurities in the liquid medicine by a layer of filter paper, but the air mixed in the transfusion tube cannot be filtered, and the air often contains harmful gas and germs. When the harmful gas or germs enter the transfusion along with air and flow into the body of a healthy person, the side effect of the transfusion and even the infection of the disease can be caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that current disposable transfusion system, at the infusion in-process, the bottle plug puncture ware slides in from the infusion medicine bottle because of patient's activity easily, provides a venous transfusion device, with the effectual fixing of bottle plug puncture ware and infusion medicine bottle, has guaranteed the stability of connecting to the landing of bottle plug puncture ware has been prevented.

The utility model discloses a following technical scheme realizes:

a venous transfusion device comprises a bottle stopper puncture outfit, a transfusion hose, a medicine adding bag, a Murphy dropper, a flow rate regulator, a liquid medicine filter, a venous needle and a clamping shell; the bottle stopper puncture outfit, the medicine adding bag, the Murphy dropper, the flow rate regulator, the liquid medicine filter and the vein needle are sequentially connected through the transfusion hose, the clamping shell is used for fixing the bottle stopper puncture outfit and the transfusion bottle and comprises a first shell and a second shell which are both in semi-cylindrical shapes, the first shell and the second shell of the clamping shell form a complete cylinder, a bottle opening positioning cavity and a puncture outfit positioning cavity are arranged inside the clamping shell along the axial direction of the cylinder, a channel for communicating the bottle opening positioning cavity and the puncture outfit positioning cavity is arranged between the bottle opening positioning cavity and the puncture outfit positioning cavity, bottle clamping holes communicated with the bottle opening positioning cavity are respectively arranged on the two bottom surfaces of the clamping shell, and the first shell and the second shell equally divide the bottle mouth positioning cavity and the puncture device positioning cavity. The bottle mouth of the infusion bottle is provided with a bulge, when a patient is infused, the first shell and the second shell of the clamping shell are clamped at the bottle mouth of the infusion bottle, so that the bulge of the bottle mouth is positioned in the bottle mouth positioning cavity of the clamping shell, in addition, a small bulge is arranged below the bottle plug puncture device in life, the bulge on the bottle plug puncture device is positioned in the puncture device positioning cavity, and the first shell and the second shell are fixed through rubber bands or clips, so that the infusion bottle and the bottle plug puncture device are firmly fixed together. When the patient pulls the infusion hose in the moving process, the bottle stopper puncture outfit and the infusion bottle can not fall off due to the effect of the clamping shell.

Furthermore, the medicine adding bag comprises an inner bag and an outer bag, the inner bag is communicated with the infusion hose, a separation cavity between the inner bag and the outer bag is a pressurizing cavity, the pressurizing cavity is externally connected with a pressurizing air bag, a switch is arranged at the joint of the pressurizing air bag and the pressurizing cavity, and the pressurizing air bag is filled with a certain amount of gas before use. During the infusion process, a certain amount of liquid medicine is stored in the medicine adding bag, when the infusion speed needs to be accelerated, a switch at the joint of the pressurizing air bag and the medicine adding bag can be opened, the gas in the pressurizing air bag is extruded and enters the outer bag of the medicine adding bag, the gas can fill the outer bag of the medicine adding bag, the inner bag is extruded, and the descending speed of the liquid medicine in the medicine adding bag is accelerated; and then the speed of the transfusion is maximized by controlling the flow rate regulator so as to aim at emergency.

Furthermore, a non-toxic organic polymer small ball with certain viscosity is arranged in the Murphy's dropper, and the density of the polymer small ball is less than that of the transfusion liquid medicine. When the infusion process is just started, liquid medicine enters the Murphy dropper, when the liquid medicine reaches a certain amount, the organic polymer small balls float in the liquid medicine due to the fact that the density of the organic polymer small balls is smaller than that of the liquid medicine, and along with the progress of the infusion process, when the infusion process is about to be completed, the organic polymer small balls gradually move to a medicine outlet of the Murphy dropper along with the descending of the height of the liquid medicine in the Murphy dropper, and due to the fact that the diameter of the organic polymer small balls is slightly larger than that of an infusion hose and the organic polymer small balls have certain viscosity, the small balls can plug the infusion hose at the medicine outlet of the Murphy dropper, and air is prevented from entering a human.

Furthermore, the infusion hoses at the liquid inlet and the liquid outlet of the medicine adding bag extend into the medicine adding bag by 10-15 mm. The infusion hoses of the liquid inlet and the liquid outlet extend into the medicine adding bag, and a small amount of liquid remained in the medicine adding bag can not be discharged after infusion is completed, so that whether the set of disposable infusion device is used or not can be conveniently identified, and the set of disposable infusion device is prevented from being used for a second time.

Furthermore, the first shell and the second shell are arranged in parallel, and a flexible connecting piece for connecting the first shell and the second shell is arranged between the two adjacent sides; the other two sides are provided with lock catches. The other side of the first shell, which is relatively provided with the soft connecting piece, is provided with a movable part of the lock catch, and the other side of the second shell, which is relatively provided with the soft connecting piece, is provided with a fixed part of the lock catch. With first casing and for the flexible connectors of second casing, even become a whole, made things convenient for the installation of card shell and deposited, both sides set up the hasp in addition, set up the movable part of hasp on one side, set up the fixed part of hasp on the other side, after will blocking the shell and fix in the card shell at infusion bottle and bottle plug puncture ware, it is fixed to block the shell through the hasp, improved the convenience of installation, shortened the time of card shell installation simultaneously, and then help improving the work efficiency of hospital or clinic.

Compared with the prior art, the utility model, following advantage and beneficial effect have:

1. by arranging the clamping shell and the corresponding bottle mouth positioning cavity and puncture outfit positioning cavity, the bottle stopper puncture outfit can not slide down from an infusion bottle when a patient walks in the infusion process.

2. The organic polymer small ball is arranged in the Murphy's dropper, so that the air is prevented from entering the vein of a patient in the infusion process to cause side effect;

3. the medicine adding bag is designed to be double-layer and comprises an inner bag and an outer bag, and a pressurizing cavity between the inner bag and the outer bag is connected with the pressurizing air bag, so that the transfusion efficiency under emergency is improved.
