Abstract
The utility model makes a request for a pharmaceutical plastic combination sealed cap, including a plastic cap, rubber pad and a capping. A very thin sealed layer in the middle of the plastic cap is divided the cap into two parts, and the lower part adopts a smooth design in which the smooth inner wall is in touch with the liquor. The rubber pad is pressed into the capping tightly, while the capping is pressed into the upper part of the plastic cap, and the capping is provided with an anti-theft ring. An easy-to-break anti-theft ring is provided in the capping, the supine surface (the surface nurses make sterilizations on) of the rubber pad adopts a plane type. The sealed cap is simple in structure, easy for injection molding, safe and reliable in use, and easy to open, lowering the standard to the raw materials, which could be domestic polypropylene, saving production cost substantially.
Description
Technical field
This utility model belongs to the medical apparatus technique field, is specifically related to a kind of medical plastic combined sealed cap, and it can be used on plastic infusion bottle or the plastic infusion bag.
Background technology
At present, the seal cover of common plastic infusion bottle or bag is made of plastics, its structure as shown in Figure 1, its outer cover 13 is connected with interior lid 14 employing clasps, accompany disc rubber blanket 12 between interior lid and the outer cover, the outer cover outside is with easy-to-pull anti-theft ring 11.During use, utilize easy-to-pull anti-theft ring 11 to tear outer cover bottom, Medicated needle of syringe and infusion needle are stung rubber blanket 12 and interior lid 14 and stretch in plastic bottle or the bag.The effect of rubber blanket is the sealing when keeping dosing and transfusion.
The shortcoming of this common plastics seal cover is: 1, production cost height: the easy-to-pull anti-theft ring molding difficulty on the outer cover is very big, must carry out modification to polypropylene with elastomer, the whole dependence on import of used elastomeric material; 2, because exterior and interior cover is a snapping, exist to connect seam, this seam is easy to produce the medicinal liquid internal hemorrhage due to trauma, medicinal liquid is contacted with outer cover material, but because for ease of the outer cover molding, outer cover material has generally all been carried out modification, material is poisonous, therefore can influence quality of liquid medicine, the grievous injury health.3, the unlatching of anti-theft ring is very inconvenient, and the nurse of hospital will be hooked draw ring with finger, draws with strength, just can draw back anti-theft ring, and is very big to nurse's injury of finger.
Defective at the existence of conventional seals lid, prior art discloses a kind of medical plastic compound seal lid (patent No. is ZL2004 20061955.X), its structure is seen Fig. 2, and it comprises a plastic cover 21, individual rubber blanket 22, a slice aluminium foil 24 and a pressure ring 23.There is very thin sealant 25 that lid is divided into two parts up and down in the middle of the plastic cover 21, the lower part of plastic cover 21 has slick inwall, contact with medicinal liquid, the top of plastic cover is equipped with rubber blanket 22, and on rubber blanket the assembling pressure ring 23, the scrobicular ring tight fit of pressure ring 23 by offering on flange and the tegmental wall, aluminium foil 24 heat-sealings are at the top of plastic cover.
There is following shortcoming in this structure in practice: 1, the aluminium foil sealing image appearance is poor; 2, the fastness of aluminium foil sealing is difficult to grasp, and seals sacrifices consisting of an ox, a sheep and a pigly, and the nurse of hospital can not tear open; Heat-sealing De Taisong, product are in sterilization, and the weld of aluminium foil and plastics will breach, makes product rejection; 3, there is pitting on the surface, site of puncture of rubber blanket, and when the nurse adopted iodine disinfection, the residue in the pitting be difficult to be removed, and residue just enters needle tubing probably when transfusion needle puncture, is input in people's the blood vessel, and people healthy caused very big harm.
Summary of the invention
This utility model is at the prior art above shortcomings, purpose provide a kind of simple in structure, be easy to make, easy-to-use medical plastic seal cover, to solve the problems referred to above that exist in the conventional art.
Goal of the invention of the present utility model realizes by the following technical solutions:
This medical plastic combined sealed cap comprises a plastic cover, a rubber blanket and a gland.Have very thin sealant that lid is divided into two parts in the middle of the plastic cover, smooth design is all adopted in the lower part, and inwall is slick, because this part contacts with medicinal liquid.Top is used to assemble rubber blanket and gland, their mutual structural relation is that rubber blanket is pressed in the gland, and the gland repress is contained in the top of plastic cover, and anti-theft ring is arranged on gland, can adopt traditional easy-to-pull anti-theft ring, split the formula anti-theft ring but preferably adopt easily to pull.
Be connected with the tight of gland for the ease of lid, the structure that plastic cover and gland have adopted the flange scrobicular ring to rabbet mutually cooperatively interacts, and has also adopted ultrasonic bonding, and lid and gland are sticked together firmly.
In addition, this patent has also changed the structure of rubber blanket, and upper surface (being that the nurse sterilizes simultaneously) the employing plane form at rubber blanket so just is easy to remove the residue on surface, just not having residue enters human body in infusion process, and then the warrantor's is healthy.
Innovation part of the present utility model is: the integrated structure of plastic cover, rubber blanket and gland is reasonable in design, and by ultrasonic bonding, lid and gland are sticked together firmly, guaranteed the sealing when product cleans and product is sterilized, and then guaranteed product quality.Changed the structure of rubber blanket, sterilized the nurse and simultaneously adopt the plane, be easy to remove the residue on surface, just not having the disinfectant residue does not enter human body in infusion process, and then the warrantor's is healthy.Change the opening ways of anti-theft ring, adopted easily to pull and split the formula anti-theft ring, can utilize instrument to open.
As seen, this medical plastic combined sealed cap is simple in structure, is easy to injection mo(u)lding, and is safe and reliable, is easy to open, and reduced raw-material requirement, adopts homemade pp material just can produce, and saves production cost greatly.
