Description

Blood drawing, injection practice teaching module

The novel creation department is a teaching module for blood drawing and injection practice, and is a medical teaching device for practicing blood drawing and needle-injecting techniques.

In order to enable medical staff to master the skills of blood sampling and injection, there are related practice teaching products on the market, most of which are made into high-simulation dummy arms, and have artificial simulation on the arm to simulate the skin of the arm. The surface layer, as well as the tube under the outer surface layer for simulating blood vessels, can be used for the practice and teaching demonstration of blood sampling and injection, but the shortcomings of this product are high cost, so after being damaged by a large number of needles If you want to buy new products again, it will cause a big economic burden.

Furthermore, the medical staff needs to actually face the patient during the blood injection, and the user does not have the feeling of facing the patient when practicing with the dummy arm, and has the disadvantage that the exercise effect is not good.

In view of the above-mentioned shortcomings, the new creators believe that it is necessary to make corrections. In order to carry out research and creation of related technologies and product design, and to uphold the excellent design concept, we will study and create the above disadvantages. After continuous efforts, we will end up It is the introduction of this new creative blood drawing and injection practice teaching module, which corrects the product structure to enhance the excellent effect of the product.

The main purpose of the novel teaching blood drawing and injection practice teaching module is to provide a blood-sampling and practicing teaching equipment for a person to wear on the arm and having a lower cost.

In order to achieve the purpose of the foregoing disclosure, the novel blood drawing and injection practice teaching module comprises a wear component, a simulation component and a liquid container component:

a wear component having a support plate, the support plate preferably being made of a hard material, the support plate being provided with a plurality of fixing straps, so that the wear component can be worn on a person's arm by the fixing strap;

An analog component having an inner layer, the inner layer is closely attached to one side of the support plate, and the inner layer is opposite to the one side of the support plate to closely fix an outer cover layer, and the outer layer The coating is made of a soft material, and the dummy component has a working tube which is made of a soft elastic material, and the working tube is buried between the inner layer and the outer layer, and The coating will be raised along the passage of the action tube to simulate the shape of the skin of the human arm along the blood vessel;

a liquid container assembly having an extracting liquid container and an injecting liquid container, wherein the extracting liquid container and the injecting liquid container are respectively connected with a connecting tube, and both of the connecting tubes are connected with a switching valve, and the switching valve is also simultaneously Acting tube connection, the switching valve is used for human operation switching, so as to switch to connect the working tube only to the connecting pipe of the extracting liquid container, or switch to make the working tube communicate only with the connecting pipe of the injection liquid container By.

In use, the dyeing liquid is first filled into the liquid container of the liquid container assembly to be used as blood, and then the wearer wears the wearing component on the arm by the wearer, and then the user can put the needle of the syringe. When it is inserted into the action tube, the switching valve is switched to connect the working tube with the connecting tube of the extracting liquid container, so the dyeing liquid in the extracting liquid container flows into the working tube for the syringe to be extracted, thereby achieving the effect of simulating blood drawing. And if the switching valve is switched so that the working tube communicates with the connecting tube of the injection container and the injection liquid is pre-filled in the syringe, the injection liquid in the syringe can be injected into the action tube and the injection liquid flows into the injection container. In order to achieve the effect of simulated injection injection, compared with the conventional artificial dummy arm, the creation is simple in structure and can effectively reduce the manufacturing cost, so even when a large number of needles are used for damage and need to replace the new product It will not cause too much economic burden, and because it can be worn on the arm, the user will have a realistic sense of the patient’s presence when using it.
