Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-cross infection applicator. Background Art

[0002] Skin diseases are chronic diseases, and most of the treatments in clinical practice are done by direct administration of drugs through external application. Using a cotton swab dipped in medicine to apply to the affected skin area was a common operation method before, but the efficiency is relatively low. The applicator is a device that puts liquid medicine inside and slowly pushes the medicine out through a push structure. However, there is usually more than one affected area on the skin, and using the same applicator head to apply medicine poses a risk of cross-infection. Later, applicators with multiple replaceable applicator heads were developed. However, some of the applicator heads of the above applicators apply medicine through a ball bearing, which is uneven. In addition, during the process of replacing the applicator head, the liquid medicine inside the applicator easily flows out from the medicine outlet, resulting in drug waste.

[0003] In view of the above problems, the present utility model is proposed. Utility Model Content

[0007] A socket is arranged on the upper surface of the applicator plate, a liquid cavity and a plurality of through holes are arranged inside the applicator plate, the upper surface of the liquid cavity is connected to the socket, and the lower surface is connected to the through holes.

[0008] Preferably, it also includes a stop plate, a limiting plate is arranged at the upper position in the socket, a lower support plate is arranged at the lower position in the socket, the stop plate is located between the limiting plate and the lower support plate, a spring is arranged between the stop plate and the lower support plate, and the upper surface of the stop plate is in contact with the lower surface of the limiting plate.

[0009] Preferably, the plurality of through holes are equidistantly distributed along the length direction and the width direction of the applicator plate, and the through holes are all connected to the sponge pad.

[0010] Preferably, the injection head is curved, and the angle of the curved position of the injection head is 45°.

[0011] Preferably, the limiting plate and the lower supporting plate are both in annular shape, and the flow-stop plate is in the shape of a disc.

[0012] Preferably, a plug-in / plug-out locking structure is provided between the injection head and the socket.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] After the liquid medicine flows out from the through hole, it can soak the sponge pad, so that the affected area of ​​the skin can be applied more evenly and the affected area can better absorb the medicine; when the applicator plate is removed from the socket and replaced with a new one, the liquid medicine remaining in the socket is blocked by the stop plate and will not flow out of the socket, thus saving medicine.
