The top of the cylindrical convex device at the upper end of the needle head is in a luer lock female joint shape, and the center of the top end of the cylindrical convex device at the upper end is provided with a recess which can be tightly connected and communicated with a luer lock male joint of a prefilled syringe. The outer side of the lower edge of the cylindrical protruding device at the upper end of the needle head is connected with the adapter in a virtual mode, the protruding device is pressed, the virtual connection is broken, the protruding device sinks into a gap below, and the needle head is exposed. The adapter can be used for sucking the medicines of the prefilled syringe and the penicillin bottle, and the application range of the adapter is expanded.

Description

Compatible painless injection adapter

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to compatible type adapter of painless injection equipment.

Background

Painless injection is also called needle-free injection, namely, when medicine is injected, a needle head is not used, and a high-pressure jet principle is used, so that the medicine liquid forms a thin liquid flow and instantly penetrates through the skin to reach the subcutaneous part. Painless injection can not only reduce the fear mood of the patient, because the liquid medicine distributes in subcutaneous dispersion, can also improve the absorptivity of medicine, and the time of onset is faster, and painless injection does not have the syringe needle to pierce skin and has also avoided "broken needle", and the security is higher.

The painless injection equipment mainly comprises a restorer, a syringe, a sterile ampoule and an adapter. The reset box is used for pressurizing the injector; the adapter is provided with a needle head and is used for connecting a penicillin bottle/prefilled syringe and a sterile ampoule and sucking the medicine for the sterile ampoule.

Most of patients with hypodermic injection have nervous emotion, and the injection part is easy to induration, so that the local skin is uneven, and even the medicine absorption is influenced, therefore, the painless injector is widely applied. However, the painless adapters for injection on the market at present are all adapters suitable for only one kind of medicine package. This not only increases the variety of adapters produced by the manufacturer, but also tends to waste adapters when a patient changes different packages of medication. Therefore, the compatible adapter not only suitable for packaging penicillin bottles, but also suitable for packaging prefilled syringes is certainly widely applied.

Disclosure of Invention

An object of the utility model is to provide a compatible type does not have pain adapter for injection can be applicable to extraction xiLin bottle and pre-filling formula injection simultaneously, enlarges the application scope of adapter.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a compatible type does not have pain adapter for injection, includes shell 1, syringe needle 2, syringe needle lower extreme fixed bed 3 and the cylindric convex device 4 in syringe needle upper end, and the syringe needle is located the adapter central line, and syringe needle lower extreme fixed bed 3 guarantees for the mounting that the syringe needle position does not change, and the syringe needle runs through lower extreme fixed bed 3 and the cylindric convex device 4 in upper end and closely wraps up by cylindric arch, and its characteristics are cylindric convex device top 6 in syringe needle upper end for luer lock female joint, and there is sunken 7 in the top center for fixed pre-filled syringe.

The outer edge of the bottom end of the cylindrical boss device 4 at the upper end of the needle head is connected with the adapter in a virtual mode 8, the lower portion of the cylindrical boss device is provided with a gap 5 with the same shape, and a spring 9 or a cam structure can be installed in the gap 5.

When adapter and xiLin bottle are connected, through pressing down, impress cylindric bellying device 4 in syringe needle upper end in below space 5, syringe needle 2 exposes this moment and impales xiLin bottle plug, and aseptic ampoule is connected to adapter another, absorbs the injection through the pull ampoule. When the adapter is connected with the prefilled syringe, the adapter and the prefilled syringe are fixed through the luer lock, the cylindrical protrusion device 4 at the upper end of the needle head is tightly connected with the liquid outlet of the prefilled syringe and communicated with the liquid outlet of the prefilled syringe, the other end of the adapter is connected with a sterile ampoule, and the injection is sucked through a drawing ampoule.

Through the structure, the compatible adapter can be simultaneously suitable for packaging penicillin bottles and prefilled syringes, and the application range of the painless adapter for injection is expanded.

Detailed Description

The following description of the present invention will be made in detail and completely with reference to the accompanying drawings, which include but are not limited to the following embodiments.

The compatible painless injection adapter comprises a shell 1, a needle head 2, a needle head lower end fixing layer 3 and a needle head upper end cylindrical protruding device 4. The needle head is positioned on the central line of the adapter, and the fixing layer 3 at the lower end of the needle head is used for positioning the needle head and ensuring the position of the needle head to be fixed. The needle head penetrates through the lower fixing layer 3 and the upper cylindrical protrusion device 4 and is tightly wrapped by the cylindrical protrusion 4. A gap 5 with the same shape is arranged below the cylindrical convex device 4 at the upper end of the needle head, and the cylindrical convex device 4 at the upper end enters the gap 5 after being pressed. The top 6 of the cylindrical convex device 4 at the upper end of the needle head is in a luer lock female joint shape, and the center of the top end of the cylindrical convex device at the upper end is provided with a recess 7 which can be tightly connected and communicated with a luer head of a prefilled syringe. The outer side of the lower edge of the needle head upper end protruding device 4 is connected with the adapter in a virtual mode 8, the protruding device 4 is pressed, the virtual connection 8 is broken, the protruding device sinks into the lower space 5, and the needle head 2 is exposed.

When using xiLin bottle, open xiLin bottleneck plastics, expose the plug, cover the adapter on xiLin bottle, press xiLin bottle, upper end bump device 4 on the adapter is oppressed to in the space 5, exposes syringe needle 2 in the middle of, and syringe needle 2 pierces xiLin bottle plug. The other end of the adapter is connected with a sterile ampoule, and the ampoule is pulled to suck the medicine.

When the prefilled syringe is used, the adapter is tightly connected with the prefilled syringe through the luer lock, the adapter is communicated with the liquid channel of the prefilled syringe at the moment, the other end of the adapter is connected with the sterile ampoule, and the ampoule is pulled to suck the medicine.

The utility model discloses the painless adapter for injection of compatible type that describes has reduced cross infection's risk for disposable article, has reduced the requirement to the material hardness. The adapter can be used for sucking the medicines of the prefilled syringe and the penicillin bottle, and the application range of the adapter for painless injection is expanded.
