Description

A zero-contact medication dispenser

Technical Field

The utility model belongs to the technical field of medical equipment, and in particular relates to a zero-contact medicine dispenser.

Background Art

During the traditional manual drug preparation process, nursing staff need to frequently come into contact with chemotherapy drugs and use syringes to add drugs. During the process, they need to repeatedly puncture bottle stoppers, load and unload needles, and repeatedly aspirate, which increases the risk of exposure of syringe needles and needle plugs. In addition, the impact force of the drug preparation process can easily lead to the generation of drug foam, affecting the quality and efficacy of the drug.

Utility Model Content

The purpose of the utility model is to solve the above technical problems and provide a zero-contact medicine dispensing device.

In order to solve the above technical problems, the technical solution adopted by the utility model is:

A zero-contact dispenser comprises a first hose, a first puncture head, a water stop clamp and a second puncture head, wherein the first puncture head and the second puncture head are respectively arranged at two ends of the first hose, the water stop clamp is clamped in the middle of the first hose, the first puncture head and the second puncture head are connected to the first hose at their connection points, and an air filter is provided at the free end of the second hose.

Furthermore, the length of the first hose is 2-3 cm.

Furthermore, the through hole of the first puncture head is opened in the middle of the side wall.

Furthermore, baffles are provided at the connections between the first puncture head, the second puncture head and the first hose.

Furthermore, the first puncture head is made of ABS plastic, and the second puncture head is made of stainless steel.

Compared with the prior art, the beneficial effects of the utility model are:

1. The nursing staff of the utility model only needs to insert the puncture needle into the liquid bag and the medicine bottle, and then use gravity to complete the configuration, reducing repeated puncture of the rubber stopper, reducing the probability of particle contamination and microbial contamination, thereby reducing the occurrence of adverse reactions to drug infusion;

2. The utility model reduces the probability of contaminating the liquid medicine and the occurrence of needlestick injuries to medical personnel by repeatedly drawing and dispensing medicine with a relative syringe;

3. The utility model can prevent the body and environment from being polluted by the splashing of medicines caused by uneven pressure in syringe dispensing, thus protecting medical staff;

4. The utility model is simple to operate and saves time. On the basis of ensuring the quality and efficacy of the medicine, it protects the dispenser and improves the work efficiency of the nursing staff.

DETAILED DESCRIPTION

The present invention will be further described below in conjunction with the embodiments and the accompanying drawings.

As shown in Fig. 1-2, a zero-contact dispenser comprises a first hose 1, a first puncture head 2, a water stop clamp 3 and a second puncture head 4. The first puncture head 2 and the second puncture head 4 are respectively arranged at both ends of the first hose 1, and a baffle 7 is provided at the connection. The through hole of the first puncture head 2 is opened in the middle of the side wall. The length of the first hose 1 is 3 cm. The water stop clamp 3 is clamped in the middle of the first hose 1. The connection between the first puncture head 2 and the second puncture head 4 and the first hose 1 is externally connected to a second hose 5, and an air filter 6 is provided at the free end of the second hose 5.

The first puncture head 2 is made of ABS plastic, and the second puncture head 4 is made of stainless steel.

The length of the first hose 1 can also be any value between 2-3 cm.

The working process of this utility model is as follows:

Step 1: The nursing staff first determines the amount of medication required according to the needs;

Step 2: Insert the first puncture head 2 into the soft plug of the liquid bag 9, insert the second puncture head 4 into the medicine bottle 8, open the water stop clamp 3, and the nursing staff holds the liquid bag 9 and lifts it to make it upside down. The medicine bottle 8 is located directly below the liquid bag 9. At this time, the liquid medicine in the liquid bag 8 flows into the medicine bottle 8 along the first hose 1 under the action of gravity. When the outflow of the liquid medicine in the liquid bag 9 reaches the preset dosage, close the water stop clamp 3; when the liquid medicine in the liquid bag 8 is less, the through hole in the middle of the first puncture head 2 can ensure that the liquid medicine flows out completely to avoid residue;

Step 3: Shake the medicine bottle 8 to fully mix the original medicine solution in the medicine bottle 8 with the incoming medicine solution;

Step 4: The nursing staff lifts the medicine bottle 8 by hand and makes it stand upside down. The liquid bag 9 is located directly below the medicine bottle 8 and the water stop clamp 3 is opened. At this time, the prepared liquid medicine in the medicine bottle 8 flows into the liquid bag 9 along the first hose 1 under the action of gravity. The proportion of the liquid medicine is completed and the liquid bag 9 can be used later.

When the liquid medicine flows up and down in the first hose 1, the first hose 1 is connected to the outside atmosphere through the second hose 5 and the air filter 6, so that the pressure of the medicine bottle 8, the liquid bag 9, the first hose 1 and the outside atmosphere are always consistent, the liquid medicine flows smoothly without impact force and foam generation during the process, thereby ensuring the quality and efficacy of the liquid medicine;

The baffle 7 on one side of the first puncture head 2 can prevent the drug from flowing back and contaminating the hands of the nursing staff;

The baffle 7 on one side of the second puncture head 4 can prevent the chemotherapy drugs in the medicine bottle 8 from splashing out and polluting the environment;

The utility model can also avoid the body and environment pollution caused by the splashing of medicine due to uneven pressure in the syringe dispensing, thereby protecting medical staff; compared with the repeated suction dispensing of the syringe, it reduces the probability of contaminating the medicine liquid and also reduces the occurrence of needle stick injuries to medical staff.
