Abstract
The invention discloses a composite seal cover of a medical infusion bag, which comprises an infusion cover body (1) and a rubber plug (2), wherein a seal layer (5) which is used for dividing the infusion cover body (1) into a rubber plug cavity (3) and a solution cavity (4) is arranged in the infusion cover body (1), the rubber plug (2) is put in the rubber plug cavity (3), a seal cover (2) is arranged on the infusion cover body (1) and connected with the infusion cover body (1) through a thread structure, and gluing points (6) are arranged on the lower end surface of the seal cover (2) and connected with a connecting ring (7) which is arranged on the outer wall of the infusion cover body (1). By adopting such a structure, the seal cover has the advantages of good seal performance and reliability in use, and the safety is guaranteed.
Description
Affiliated technical field
The present invention relates to a kind of medical seal cover, particularly a kind of transfusion bag composite seal cap for medical purpose.
Technical background
The utility model patent that a kind of name is called " compound plastic seal lid for medical use of easily tearing " is disclosed in CN2834524, the sealing lid includes outer cover and interior lid, adopt clasp to be connected between outer cover and the interior lid, accompany the disc rubber cushion between interior lid and the outer cover, the outer cover outside is with draw ring.There is following shortcoming in the seal cover of this structure: 1. what adopt between outer cover and the interior lid is that clasp is connected, exist between outer lid body and the interior lid and be connected the slit, this slit is easy to make the medicinal liquid internal hemorrhage due to trauma, cause medicinal liquid to contact with outer cover, because the outer cover material is poisonous, has so just caused the pollution to medicinal liquid.2. because the molding difficulty of outer cover is very large, cause production cost high.
The utility model patent that a kind of name is called " compound plastic seal lid for medical use " is disclosed in CN2626482, it includes a plastic cover, at least one rubber blanket and an aluminium foil, lid has wall section and bottom and is made by injection moulding integral body, has the groove that equates with rubber blanket quantity that stretches out towards the seal cover inboard in the bottom, close fit rubber blanket in the groove, aluminium foil is attached to the outside of bottom to cover rubber blanket, and the part of aluminium foil is freely stretched out from the bottom.Although the seal cover of this structure has overcome the medicinal liquid internal hemorrhage due to trauma, cause the shortcoming to liquid medicine contamination, but still there is such deficiency in this structure: the combination that adopts between rubber blanket and the lid is the assembling mode that the groove projection cooperatively interacts, when using when infusing, tear aluminium foil, plug transfusion needle, then bottle is stood upside down, do like this being easy to make rubber blanket to come off, cause medicine liquid leakage.
Summary of the invention
Purpose of the present invention just provides a kind of simple in structure, good airproof performance, service-strong transfusion bag composite seal cap for medical purpose.
The objective of the invention is to realize by such technical scheme, a kind of transfusion bag composite seal cap for medical purpose, include infusion cover body and plug, in the infusion cover body, be provided with a sealant that the infusion cover body is divided into plug chamber and medicinal liquid cavity, plug is placed on the plug intracavity, be provided with seal cover at the infusion cover body, described seal cover is connected with the infusion cover body by helicitic texture, the described gummed point that is provided with in the seal cover lower surface, described gummed point is connected with connecting ring on being arranged on infusion cover body outer wall.
Further, described gummed point 6 is 8, and is circumferentially evenly distribution.
During use, the twisting seal cover so that gummed point fracture, stretches into Medicated needle of syringe and infusion needle thorn seep through plug and sealant in the transfusion bag and to get final product.
The technique effect that the present invention obtains is: adopt this structure to make the good airproof performance of seal cover, use reliably, safety has obtained guarantee.
Description of drawings
Description of drawings of the present invention is as follows:
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Embodiment 1: as shown in Figure 1, a kind of transfusion bag composite seal cap for medical purpose, include infusion cover body 1 and plug 2, in infusion cover body 1, be provided with a sealant 5 that infusion cover body 1 is divided into plug chamber 3 and medicinal liquid cavity 4, plug 2 is placed in the plug chamber 3, be provided with seal cover 2 at infusion cover body 1, described seal cover 2 is connected with infusion cover body 1 by helicitic texture, the described gummed point 6 that is provided with in seal cover 2 lower surfaces, described gummed point 6 is connected with connecting ring 7 on being arranged on infusion cover body 1 outer wall.
Further, in order to be connected firmly, described gummed point 6 is 8, and is circumferentially evenly distribution.
