Abstract

The liquid medicine rectum injector discloses an apparatus giving medicine liquid to rectum applicable to all demanding medicine liquid for rectums, which comprises a nipple element (1) and a body element (2). A nipple is connected with the front central end shaped in hollow type of the body element together. Liquid medicine shall be sucked into injector tube through the nipple when using, inserting the nipple 2-5 cm inside the ass, then injecting the liquid medicine into the rectum. Most liquid medicine absorbed at the end of rectum enters body circulation directly.

Description

Medicinal liquid rectum infusion appliance

(1) technical field: this utility model relates to a kind of utensil of medicinal liquid rectally.

(2) background technology: oral administration is the most frequently used route of administration, but the medicine that this route of administration absorbs because of gastrointestinal will be from intestinal wall access door Venous system, so medicine circulates first and must pass through liver, consequently medicine has been subjected to enter the body circulation through hepatic vein again after the influence of hepatic metabolism or association reaction, thereby reduced effective blood drug concentration, and oral administration absorbs slow, produce effects is also slow, bioavailability of medicament differs greatly, thereby influencing its curative effect of medication (sees and wears the spedex chief editor: the special medicine handbook of practical new drug, the 3rd edition, People's Medical Officer Press, in October, 2003, the 11st page).Discover in a large number, if medicinal liquid adopts rectally, the concentration of its blood medicine and reach similar to intravenous administration around (see that Meng Xian relaxes, Li Huanqiu writes: pharmaceutics of Chinese drugs, People's Health Publisher,, the 277th page in 1996) of peak concentration.So medicinal liquid has the advantages that as adopting rectally produce effects is fast, curative effect is high, is a kind of route of administration of worth promotion.But the ordinary straight enteral administration is not owing to there is special administration apparatus, and not only dosage is wayward, and rectally is often dark excessively, is unfavorable for that inferior rectal veins absorbs, thereby influences its curative effect of medication performance.

(3) summary of the invention: the purpose of this utility model provides a kind of medicinal liquid rectum infusion appliance, solves inaccurate, wayward this technical problem of the administration degree of depth of ordinary straight enteral administration dosage.Medicinal liquid rectum infusion appliance is made by silicon moulding material heating back one-shot forming, finished product inside and outside wall surface smoothness height, translucent.Divide pars papillaris, body two parts, pars papillaris is front fine and rear thick open circles taper, and the nipple appearance has length mark, is convenient to grasp the insertion anal degree of depth.It is cylindric that body is, and is divided into the socket of periphery and piston inside, and piston can move forward and backward in socket.This utility model has following beneficial effect: 1, because the rectally degree of depth is 2～5cm, just belonging to the inferior rectal veins absorption site, medicinal liquid is being absorbed through this vein directly enter the body circulation, keeping away the first benefit of crossing of liver, thereby improve drug effect.2, the medicinal liquid rectum infusion appliance injection degree of depth is easy to control, liquid dose is accurate.3, not needing anal canal or enema tube to insert can retention enema or rectally.4, this appliance applications is convenient, all can be applicable in village clinic, community medicine point, family etc., and cheap.

(4) description of drawings: Fig. 1 is a schematic appearance, and Fig. 2 is a center longitudinal profile sketch map.This utensil comprises rectum infusion appliance pars papillaris (seeing that accompanying drawing 1 shows 1), body (seeing that accompanying drawing 1 shows 2), and nipple and body front end face central authorities are hollow shape and are connected to an integral body.Rectum infusion appliance nipple is front fine and rear thick open circles taper, long 5cm (seeing accompanying drawing 2), and nipple is diameter 5mm foremost, and the smooth surface circle is blunt.Nipple rearmost end (linking to each other outward) diameter 7mm with body, open circles taper nipple Zhou Bihou 1mm.The nipple appearance has length mark (cm), is convenient to grasp the insertion anus degree of depth.Rectum infusion appliance body is cylindric, is divided into the socket of periphery and piston two parts inside: the long 150mm of socket, and outer circumference diameter 32mm, socket Zhou Bihou 1.5mm, the socket rear end is to periphery projection 3mm (prominence outer circumference diameter 38mm).The socket outer wall has milliliter (ml) scale sign, so that control rectally dosage.Piston can move forward and backward in socket, and tight with socket sealing, piston is the hollow cylinder of sealing, long 160mm, and external diameter 29mm seals hollow internal diameter 26mm, and piston rear end is also to periphery projection 3mm, prominence outer circumference diameter 35mm.

(5) specific embodiment: elder generation in nipple is pumped into the rectum infusion appliance, inserted medicinal liquid anal 2～5cm with nipple and medicinal liquid can be injected internal rectum when medicinal liquid rectum infusion appliance was used.
