Abstract
The utility model relates to a compound sealing cap for the medical infusion bag, which comprises an infusion cover body (1) and a rubber plug (2). A sealing layer (5) which splits the infusion cover body (1) into a rubber plug cavity (3) and a medicine liquor cavity (4) is arranged in the infusion cover body (1), the rubber plug (2) is positioned in the rubber plug cavity (3), and a sealing cap (7) with a draw ring (6) is arranged on the rubber plug cavity (3), and the sealing cap (7) and the rubber plug cavity (3) are connected into a whole and cause the rubber plug (2) to be sealed in the rubber plug cavity (3). The adoption of the structure ensures that the sealing of the compound sealing cap is good, the use is reliable, and the security is ensured.
Description
Affiliated technical field
This utility model relates to a kind of medical seal cover, particularly a kind of medical infusion bags compound seal lid.
Technical background
The utility model patent that a kind of name is called " the medical plastic compound seal lid 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 big, cause the production cost height.
The utility model patent that a kind of name is called " medical plastic compound seal lid " is disclosed in CN2626482, it includes a plastic cover, at least one rubber blanket and an aluminium foil, lid has wall portion 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, to cover rubber blanket, freely stretch out from the bottom by the part of aluminium foil attached to the outside of bottom for aluminium foil.Though the seal cover of this structure has overcome the medicinal liquid internal hemorrhage due to trauma, cause 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 being easy to make rubber blanket to come off like this, cause medicine liquid leakage.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, good airproof performance, service-strong medical infusion bags compound seal lid.
The purpose of this utility model is to realize by such technical scheme, it has transfusion to cover body and plug, cover in transfusion and to be provided with one in the body and will to infuse and cover the sealant that body is divided into plug chamber and medicinal liquid cavity, plug is placed on the plug intracavity, the plug chamber is provided with the seal cover of a band draw ring, seal cover is connected with the outer wall in plug chamber, and plug is sealed in the plug intracavity.
During use, the pulling draw ring is torn transfusion and cover the top of body, Medicated needle of syringe and infusion needle are stung seep through plug and sealant and stretches in the transfusion bag.Because seal cover is sealed in the plug intracavity with the inwall in plug chamber with plug, makes plug can not come off out from the plug intracavity because of handstand, has prevented that medicinal liquid from spilling, guaranteed the safety of transfusion.Simultaneously, it is one-shot forming that body is covered in transfusion, and the situation of seepage can not take place medicinal liquid, has guaranteed that medicinal liquid can not polluted.
The technique effect that this utility model is obtained 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 utility model is as follows:
Fig. 1 is first kind of sectional structure sketch map of this utility model;
Fig. 2 is second kind of sectional structure sketch map of this utility model;
Fig. 3 is a STRUCTURE DECOMPOSITION sketch map of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, 2, 3, this utility model includes transfusion and covers body 1 and plug 2, cover in transfusion and to be provided with one in the body 1 and will to infuse and cover the sealant 5 that body 1 is divided into plug chamber 3 and medicinal liquid cavity 4, plug 2 is placed in the plug chamber 3, plug chamber 3 is provided with the seal cover 7 of a band draw ring 6, seal cover 7 connects into an integral body with plug chamber 3, and plug 2 is sealed in the plug chamber 3.
During use, pulling draw ring 6 is torn transfusion and cover the top of body 1, Medicated needle of syringe and infusion needle are stung seep through plug 2 and sealant 5 and stretches in the transfusion bag.Because seal cover 7 is sealed in the plug intracavity with the inwall in plug chamber 3 with plug 2, the plug 2 that makes can not come off out in plug chamber 3 because of handstand, has prevented that medicinal liquid from spilling, and has guaranteed the safety of transfusion.Simultaneously, it is one-shot forming that body 1 is covered in transfusion, and the situation of seepage can not take place medicinal liquid, has guaranteed that medicinal liquid can not polluted.
Shown in Fig. 1,3, seal cover 7 is connected like this with plug chamber 3: the wall of seal cover 7 is provided with and seal cover 7 all-in-one-piece V-ring platforms 8, the wall in plug chamber 3 is provided with the V-ring groove 9 that matches with V-ring platform 8, and V-ring platform 8 is connected into an integral body with V-ring groove 9 by the microwave arc welding.Do that like this plug 2 is sealed in the plug chamber 3 closely, in the time of clinical use, the plug 2 that can make because of bottle is stood upside down does not come off.Certainly, as shown in Figure 2, seal cover 7 also can be connected like this with plug chamber 3: the wall of seal cover 7 is provided with and seal cover 7 all-in-one-piece V-ring grooves 9, the wall in plug chamber 3 is provided with the V-ring platform 8 that matches with V-ring groove 9, and V-ring platform 8 is connected into an integral body with V-ring groove 9 by the microwave arc welding.
As shown in Figure 1, 2, 3, the dome 10 of 3 bottoms, plug chamber is provided with aerofluxus breach 11.On the inwall in plug chamber 3, axially be provided with air discharge duct 12.When plug 2 assembles in plug chamber 3, air in the plug chamber 3 can make plug 2 produce the phenomenon of emitting lid, owing to had aerofluxus breach 11 and air discharge duct 12, too much air is just discharged to the external world by aerofluxus breach 11 and air discharge duct 12, has avoided emitting the generation of covering phenomenon.
As shown in Figure 1, 2, 3, described aerofluxus breach 11 is 4, and is circumferential uniform distribution.Described air discharge duct 12 is 4, and is circumferential uniform distribution.Certainly aerofluxus breach 11 and air discharge duct 12 also can be set as required.
