CN210750879U - Painless venous patch - Google Patents

Abstract

A painless venous patch, which comprises a basal layer, and the basal layer includes an anesthetic ointment; an annular protrusion is formed on the lower side of the basal layer, and the anesthetic ointment is accommodated in the annular protrusion; around the annular protrusion, a lower side of the basal layer is further formed with Medical adhesive; a ring-shaped gasket is fixed on the upper side of the base layer, and the gasket is made of loose material; the gasket contains white tea polyphenol powder; the upper side of the gasket is covered with a transparent plastic film, so that the white tea polyphenols The powder is confined between the transparent plastic film and the base layer. In the painless venous patch of the present application, the air enters the white tea polyphenol powder after passing through the loose gasket. After a predetermined period of time, all the tea polyphenol powder surrounded by the gasket turns reddish brown, thereby indicating that the user has When the optimal duration of anesthesia is reached, venipuncture can be performed.

Description

Painless venous patch

technical field

The utility model relates to a medical patch, in particular to a painless vein patch.

Background technique

CN202538152U discloses a superficial anesthesia applicator for venipuncture, which is used for sticking on the surface of a patient to be punctured to anesthetize the patient's skin, so that the patient will not feel pain during puncture, which is especially suitable for For venipuncture in infants and young children.

Anesthetic ointment is usually compound lidocaine cream. It usually takes 1 hour for the anesthetic ointment to be applied to the patient's skin surface to act as anesthesia. That is, the drug will penetrate into the skin and anesthetize the skin tissue for 1 hour after the application.

Therefore, after the surface anesthesia applicator is attached, the applicator can be removed and punctured after a predetermined period of time; if the applicator is removed and punctured before the time is up, it is very likely that the skin is not effectively anesthetized. It would be very troublesome if the doctor or nurses timed the applicator for each patient to ensure the efficacy of the drug, especially in the vaccine injection room, where many infants and young children would be concentrated, making it difficult to monitor the time.

Utility model content

In view of the above problems, the present application aims to provide a painless venous patch, which can instruct the user after a predetermined time to remind the user that the optimal anesthesia time has come.

The painless venous patch of the present application includes a basal layer, and the basal layer includes anesthesia ointment;

An annular bulge is formed on the lower side of the base layer, and the anesthetic ointment is accommodated in the annular bulge; around the annular bulge, a medical adhesive is also formed on the lower side of the base layer;

A ring-shaped gasket is fixed on the upper side of the base layer, and the gasket is made of loose material; the gasket contains white tea polyphenol powder; the upper side of the gasket is covered with a transparent plastic film, thereby confining the white tea polyphenol powder to the transparent surface. between the plastic film and the base layer.

Preferably, the medical adhesive is provided with release paper.

Preferably, the painless venous patch is vacuum sealed in a packaging bag.

Preferably, the upper side of the base layer is coated with reference color patches.

In the painless venous patch of the present application, the air enters the white tea polyphenol powder after passing through the loose gasket. After a predetermined period of time, all the tea polyphenol powder surrounded by the gasket turns reddish brown, thereby indicating that the user has When the optimal duration of anesthesia is reached, venipuncture can be performed.

Detailed ways

Hereinafter, the painless venous patch of the present application will be described in detail with reference to the accompanying drawings.

The painless venous patch of the present application includes a base layer 10 , the base layer 10 is made of medical plastic or silica gel, and the base layer 10 includes an anesthetic ointment 13 .

An annular protrusion 12 is formed on the lower side of the base layer 10, and the anesthetic ointment 13 is accommodated in the annular protrusion 12; around the annular protrusion 12, a medical adhesive 11 is also formed on the lower side of the base layer 10; The adhesive 11 is separated from the anesthetic ointment 13 to prevent the adhesive from deteriorating the anesthetic ointment. Here, the anesthetic ointment is an anesthetic ointment that should be used in the prior art, and is generally a compound lidocaine ointment.

An annular gasket 14 is fixed on the upper side of the base layer 10, and the gasket 14 is made of loose material, such as gauze, non-woven fabric, etc.; the gasket 14 contains white tea polyphenol powder; the upper side of the gasket 14 is covered with a transparent plastic film 16 , thereby confining the white tea polyphenol powder between the transparent plastic film 16 and the base layer 10 . The medical adhesive 11 is provided with release paper, and the release paper is peeled off during use. The painless venous patch is sealed in a vacuum bag20, and the tea polyphenols are prevented from contacting with the air during storage. The upper side of the base layer 10 is coated with a reference color block, so as to facilitate the user to judge whether the optimal anesthesia duration is achieved.

When in use, tear open the packaging bag 20, peel off the release paper covered on the medical adhesive on the lower side of the base layer, and then align the anesthetic ointment in the annular bulge on the lower side of the base layer at the position to be punctured, so that there is no pain. The venous patch is attached to the skin of the person to be punctured. The air continuously enters it through the loose material gasket, and reacts with the tea polyphenols surrounded by the gasket, so that the surrounded tea polyphenols continuously turn reddish brown; when all the surrounded tea polyphenols are oxidized, The optimal length of anesthesia time. At this time, the color of the surrounded tea polyphenols is the same as the color of the control color block. At this time, the user can peel off the painless venous patch from the skin surface and prepare for venipuncture.
