Abstract
The utility model discloses a sealing cover without an inner cover. The sealing cover is a single cover body, wherein external screw threads connected with a medicament mixer are arranged on the outer wall of the sealing cover. When the sealing cover without the inner cover is used, the sealing cover is welded on a connecting opening of an infusion container, a connecting opening of the medicament mixer is screwed on the external screw threads of the sealing cover, the screwing part can be also welded in a heating way, and then sealing connection is achieved. The medicament mixer is connected with the sealing cover through a screw thread structure or is welded after connection, so the connection is firmer and the sealing effect is better.
Description
Technical field
This utility model relates to a kind of infusion vessel accessory, relates in particular to a kind of seal cover that does not have inner cap.
Background technology
In clinical treating disease, perhaps directly medicine is injected in the body often for patient infusion through intravenous drip, medicine often is stored in the infusion vessel, and the medicinal liquid in the infusion vessel injects or output all need be through the interface realization.
In the prior art, mainly adopt the tubular conduit seam on infusion vessel, as interface, an end seam of tubular conduit seals through sealing-plug in the port of the other end on infusion vessel with this tubular conduit.
Mainly there is following deficiency in the interface of above-mentioned seam on infusion vessel: the outer wall of interface is the slick face of cylinder; When being connected with the connector of the medicine mixer mode through seam; This interface combines comparatively difficulty with the connector of medicine mixer; Cause the qualification rate of thermal weld not high, cause leakage easily.
The utility model content
To the above-mentioned deficiency that exists in the prior art, this utility model provides seal cover a kind of and the no inner cap that connector medicine mixer is used.
In order to solve the problems of the technologies described above, this utility model has adopted following technical scheme: the seal cover of no inner cap, and sealing lid is single lid, the outer wall of seal cover is provided with and is used for the external screw thread that is connected with medicine mixer.
As a kind of preferred version of this utility model, the top of said seal cover is provided with mixes medicine passage, the bottom seals of said mixed medicine passage.
As the another kind of preferred version of this utility model,, the sealing lid also comprises the rubber cushion pressing plate; Be provided with sealing-plug in the said mixed medicine passage, the inwall circumference that mixes the medicine passage is provided with inner groovy, and said rubber cushion pressure board is in inner groovy and be pressed on the sealing-plug.
As another preferred version of this utility model,, said infusion channel is made up of circular channel and conicylindrical passage, and said conicylindrical passage is positioned at the bottom of circular channel, and the bottom of conicylindrical passage is the arc surface transition.
As a kind of improvement project of this utility model, the external screw thread of said seal cover is provided with the connector anti-slip equipment that reverse rotation is withdrawed from external screw thread that prevents medicine mixer.
As the another kind of improvement project of this utility model, said anti-slip equipment is for falling only card of zigzag.
The beneficial effect of this utility model is: when using the seal cover of this no inner cap; At first sealing is covered seam on the interface of infusion vessel, the connector of medicine mixer is enclosed within on the external screw thread of sealing lid, also can be with the rotation set position through the mode of heating seam; And then reach and be tightly connected; Seam again after medicine mixer is connected or connects through helicitic texture and sealing lid, not only connection is more firm, and sealing effectiveness is better.
Description of drawings

Fig. 2 is the structural representation of the seal cover embodiment two of no inner cap;
Fig. 3 is the structural representation of the seal cover embodiment three of no inner cap.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done to describe in further detail.
Fig. 1 is for the structural representation of the seal cover embodiment one of no inner cap, and is as shown in the figure.The seal cover of no inner cap, sealing lid 1 is single lid, the outer wall of seal cover 1 is provided with and is used for the external screw thread 2 that is connected with medicine mixer.When using the seal cover of this no inner cap; At first sealing is covered 1 seam on the interface of infusion vessel, the connector of medicine mixer is enclosed within on the external screw thread 2 of sealing lid, also can be with the rotation set position through the mode of heating seam; And then reach and be tightly connected; Seam again after medicine mixer is connected or connects through helicitic texture and sealing lid, not only connection is more firm, and sealing effectiveness is better.When mixing medicine, the top that only needs the following needle-penetration sealing of the crosspointer in the medicine mixer is covered just can be communicated with infusion vessel and medicament reservoir.
Fig. 2 is the structural representation of the seal cover embodiment two of no inner cap; The difference of Fig. 2 and Fig. 1 is: the seal cover of the no inner cap among the embodiment two also comprises rubber cushion pressing plate 4; The top of seal cover 1 is provided with mixes medicine passage 3, and the bottom seals of mixing medicine passage 3 is provided with sealing-plug 5 in mixed medicine passage 3; The inwall circumference that mixes medicine passage 3 is provided with inner groovy, and rubber cushion pressing plate 4 is stuck in the inner groovy and is pressed on the sealing-plug 5.When mixing medicine, take off rubber cushion pressing plate 4, only need the following needle-penetration of the crosspointer in the medicine mixer should be mixed the sealing-plug 5 of medicine passage 3 bottoms and the hermetically-sealed construction of bottom, just can infusion vessel and medicament reservoir be communicated with.
Fig. 3 is the structural representation of the seal cover embodiment three of no inner cap; The difference of Fig. 3 and Fig. 1 only is: the top of seal cover 1 is provided with mixes medicine passage 3; Infusion channel 3 is made up of circular channel 31 and conicylindrical passage 32; Conicylindrical passage 32 is positioned at the bottom of circular channel 31, and the bottom of conicylindrical passage 32 is the arc surface transition.When mixing medicine, the bottom that only needs the following needle-penetration of the crosspointer in the medicine mixer to be mixed medicine passage 3 just can be communicated with infusion vessel and medicament reservoir.Certainly, the structure of infusion channel 3 also is not limited to said structure, also can adopt following structure, and infusion channel 3 is that port is big, the conical structure that the bottom is little, and the bottom of infusion channel 3 is the arc surface transition.
The external screw thread 2 of seal cover 1 is provided with the connector anti-slip equipment that reverse rotation is withdrawed from external screw thread 2 that prevents medicine mixer.In the present embodiment, anti-slip equipment is that zigzag only blocks 6.The zigzag of falling that zigzag only blocks in 6 connectors that need with medicine mixer of falling on seal cover 1 outer wall is ended card and is used.The connector of medicine mixer is enclosed within on the external screw thread 2 of sealing lid 2; When perhaps the mode of heating seam is passed through at the rotation set position; Only block 6 and on reverse, have barrier effect because of falling zigzag, the female thread of avoiding the medicine mixer of rotation set on seal cover 1 withdraws from from the external screw thread of seal cover 1.
Explanation is at last; Above embodiment is only unrestricted in order to the technical scheme of explanation this utility model; Although with reference to preferred embodiment this utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model; And not breaking away from the aim and the scope of this utility model technical scheme, it all should be encompassed in the middle of the claim scope of this utility model.
