Abstract
The utility model discloses a kind of no-needle transfusion bag joint, it comprises joint (3) and sealing ring (2), wherein, through hole (1) is provided with in joint (3), the bottom of joint (3) is rhombus base (5), sealing ring (2) is arranged in through hole (1), is provided with conduit through hole (4) in sealing ring (2), and the large end of conduit through hole (4) is provided with diaphragm seal (6).The beneficial effects of the utility model are: medicinal liquid can be derived without the need to using sharp-pointed syringe needle to thrust in joint by using the conduit of tack by this device, manufacture some residues when avoiding syringe needle to thrust in joint thus block syringe needle or flow in tube for transfusion, and this device has, and clamping is reliable, good airproof performance, advantage easy to use.
Description
Technical field
This utility model relates to transfusion bag joint, particularly a kind of no-needle transfusion bag joint.
Background technology
According to investigation, the inpatient of China more than 98% all uses venous transfusion as base therapy means.And transfusion bag can be shunk under the influence of air pressure due to self and seem convenient without the need to using breather, its use is also increased gradually.Before transfusion, need syringe needle to thrust in bottle stopper, so that liquid can flow out, but sharp-pointed due to syringe needle, some materials in small, broken bits can be made to be stung to fall to being mixed in medicinal liquid, thus medicinal liquid is polluted or blocks syringe needle.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, the no-needle transfusion bag joint providing a kind of structure simple, easy to use, medicinal liquid can be derived without the need to using sharp-pointed syringe needle to thrust in joint by using the conduit of tack by this device, manufactures some residues thus block syringe needle or flow in tube for transfusion when avoiding syringe needle to thrust in joint.
The purpose of this utility model is achieved through the following technical solutions: a kind of no-needle transfusion bag joint, it comprises joint and sealing ring, wherein, through hole is provided with in joint, the bottom of joint is rhombus base, sealing ring is arranged in through hole, is provided with conduit through hole in sealing ring, and one end of conduit through hole is provided with diaphragm seal.
Described through hole is shoulder hole.
Described sealing ring is arranged in the macropore of through hole by interference fit.
Described conduit through hole is bellmouth, and its outside diameter is greater than the diameter of the conduit thrust in joint, and its central diameter is less than the diameter of the conduit thrust in joint, and diaphragm seal is arranged at the large end of conduit through hole.
Described diaphragm seal is provided with projection, and projection is clamped between through hole and sealing ring.
This utility model has the following advantages: medicinal liquid can be derived without the need to using sharp-pointed syringe needle to thrust in joint by using the conduit of tack by this utility model, manufacture some residues when avoiding syringe needle to thrust in joint thus block syringe needle or flow in tube for transfusion, and this device has, and clamping is reliable, good airproof performance, advantage easy to use.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of no-needle transfusion bag joint.
In figure, 1-through hole, 2-sealing ring, 3-joint, 4-conduit through hole, 5-rhombus base, 6-diaphragm seal.
Detailed description of the invention
Be further described this utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, a kind of no-needle transfusion bag joint, it comprises joint 3 and sealing ring 2, wherein, through hole 1 is provided with in joint 3, in the present embodiment, described through hole 1 is shoulder hole, the bottom of joint 3 is rhombus bases 5, in the present embodiment, described sealing ring 2 is arranged on by interference fit in the macropore of through hole 1, conduit through hole 4 is provided with in sealing ring 2, in the present embodiment, described conduit through hole 4 is bellmouth, its outside diameter is greater than the diameter of the conduit thrust in joint, its central diameter is less than the diameter of the conduit thrust in joint, diaphragm seal 6 is arranged at the large end of conduit through hole 4, described diaphragm seal 6 is provided with protruding 61, protruding 61 are clamped between through hole 1 and sealing ring 2.
Work process of the present utility model is as follows: during use, the conduit of tack is thrust in conduit through hole 4 from bringing out greatly of conduit through hole 4, diaphragm seal 6 is brought into conduit through hole 4 by conduit, because protruding 61 are clamped between through hole 1 and sealing ring 2, diaphragm seal 6 can not come off, and conduit is made it to drop by the clamping of the conduit through hole 4 of taper.
Claims (5)
