Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to an ointment applying device with flow control and blocking functions.
Background
The ointment is a semisolid pharmaceutical preparation containing lipid or oil substances (such as vaseline, lard, and lanolin) as matrix for skin, and belongs to external preparations for transdermal administration. Transdermal absorption of drugs involves the release, penetration and absorption of the drug into the blood circulation in three stages. The process of absorption of drugs applied to the skin through sweat gland channels, transport through the stratum corneum and transport through the deep layers of the epidermis is called transdermal absorption. Transdermal absorption is the absorption of drugs through the skin to achieve the purpose of medication and treatment, and is undoubtedly the first to be mentioned from the physiological structure of the skin. The skin is composed of many layers of tissues, mainly including epidermis, dermis and subcutaneous adipose tissue, wherein the pilosebaceous glands and sweat glands of the subcutaneous adipose tissue are open in the epidermis. The outermost layer of the epidermis is the stratum corneum, which is a natural barrier to the skin by the lamination of dense, keratinized, inanimate cells. The transdermal absorption of the drug can reach the focus through the following three routes: hair follicles, intact stratum corneum, sweat glands. When a drug passes through the outermost cells of the epidermis or between the cells of the stratum corneum into the skin, the stratum corneum acts as a rate-limiting barrier to drug penetration and the rate of drug diffusion through the stratum corneum is enhanced. It is known that skin absorption is mainly completed through stratum corneum cells, intercellular spaces, or through hair follicles and sebaceous glands. The drug with small molecular weight is absorbed quickly and can diffuse into the stratum corneum of the barrier; the drugs with higher molecular weight are mostly diffused through pores and sweat glands.
Generally, the externally applied ointment is mainly used for local skin detumescence, pain relief, infection resistance and wound healing promotion, and does not make precise requirements on the applied dosage, such as erythromycin ointment, Baiduobang ointment and the like. However, the medicine such as compound lidocaine ointment has requirements on dosage according to different operation time and operation area. At present, the ointment is mostly applied by cotton swabs clinically, but the ointment has the defects of uncertain application area or need to mark an application area, namely an affected part in advance; the smearing thickness is uneven, which influences the absorption of the skin of a patient and the final anesthetic effect; the cotton swab has certain absorption capacity, and errors can be caused when the medicine is used; meanwhile, the cotton swab is smeared, so that the transmission procedure of the medicine is prolonged, and the pollution probability is increased; part of the ointment remains on the cotton swab, which causes waste.
The prior Chinese patent with publication number CN204092832U and name of an ointment external applicator provides an ointment external applicator which has the advantages of accurate administration dosage, reduced medicine waste, and enhanced accuracy and safety of anesthesia, compared with the traditional cotton swab application mode, the ointment external applicator reduces the transfer process of medicines, avoids the secondary pollution of medicines and the waste generated in the transfer process, ensures accurate dosage of the ointment and even application, provides convenience for the preparation of clinical operation, and increases the safety of superficial skin operation. However, including the above-mentioned documents, the ointment is usually applied from a metal or plastic tube having a metal or plastic tip which is easily smeared with excess ointment and greasy. Contamination of the tip of the tube is a problem and there is no way to regulate the amount of medicament dispensed from the tube.
