Description

The built-in obstruct valve that leads to

Technical field

This utility model relates to the built-in obstruct valve that leads in the powder and liquid double-chamber transfusion bag of medical packaging container, and it is suitable for two Room on the powder and liquid double-chamber transfusion bag of built-in powder and liquid double-chamber transfusion bag of leading to baffling device and band medicine filling mouthpiece and connects.

Background technology

The powder and liquid double-chamber transfusion bag of researching and developing at present has multiple: wherein a kind of is with built-in powder and liquid double-chamber transfusion bag of leading to baffling device, adopt real welding line that soft bag is divided into two Room, with the built-in baffling device that leads to two Room are connected, the two or more different pharmaceuticals of packing, two Room are not connected in sterilization and the transporting procedures, lead to baffling device connection and mix medicine built-in artificially during use; Another kind of powder and liquid double-chamber transfusion bag for the band medicine filling mouthpiece, medicine powder is contained in the inner chamber of medicine filling mouthpiece, interface afterbody band easy-to-fold cap, liquid preparation is contained in the soft bag, easy-to-fold cap artificially fractures during use, can use after the medicine of interface inner chamber (i.e. coyote hole) and soft bag (being another coyote hole) is mixed, in fact but it also plays a part the Nei Tong baffling device, the former also has this device of use, and its advantage is simple in structure, but easy-to-fold cap is relatively more fragile, in transporting procedures, fractureed prematurely sometimes, cause the medicine newspaper to decrease, may produce microgranule when fractureing, influence the use of medicine.

Summary of the invention

At above-mentioned technical deficiency, this utility model provides in a kind of sterilization and the storing sealing reliable, and is easy to use and do not produce the built-in obstruct valve that leads to of microgranule.

The technical scheme that its technical problem that solves this utility model adopts is: it is made up of valve seat and spool and both sealing member valve pockets, on an end face of valve pocket, has a passage at least, the hole that radially has corresponding also energy with passage and passage to be connected of spool, the poppet shaft that is positioned at another end face one side of valve pocket has blind hole in the heart, blind hole is connected with the hole that the footpath makes progress, and the blind hole end is positioned at passage one side of valve pocket.Valve seat and spool adopt the polypropylene for medical article material, valve pocket then adopts rubber (as butyl rubber) or plastic material, goodish elasticity and plasticity are arranged, sealing is reliable, faying face between valve seat and the valve pocket is preferably the non-face of cylinder, and the faying face between spool and the valve pocket adopts the face of cylinder (or taper seat), though seal between them, but spool still can be at the valve pocket internal rotation, and can not produce microgranule.On the peripheral surface of valve pocket, also the multiple tracks bulge loop can be set up, the sealing property between it and the valve seat can be further strengthened.Cannelure is arranged on the spool, and cannelure one end next-door neighbour's valve pocket (3) is another end face of tape channel (4) not, and cannelure radially intersects with blind hole, and two bags medicinal liquid can both flow to end automatically., technology suitable as material reaches a standard, and this valve can be made up of on the end face that passage is located at valve seat valve seat and spool, and the structure of spool as hereinbefore.

The beneficial effects of the utility model are: dependable performance, and simple in structure, do not produce microgranule in the use.

Specific embodiments

This utility model is made up of valve seat (1), spool (2) and both sealing member valve pockets (3), on an end face of valve pocket (3), has a passage (4) at least, general passage (4) distributes in spool (2) lateral symmetry, the hole (5) that spool (2) radially has an energy and passage (4) to be connected, be positioned on the axle center of spool (2) of valve pocket (3) other end one side blind hole (6) is arranged, blind hole (6) is connected with radial hole (5), and the blind hole end of blind hole (6) is positioned at valve pocket (3) passage (4) one sides.When hole (5) rotate to passage (4) trailing position with spool (2) (position shown in accompanying drawing 1, accompanying drawing 2), this utility model is in closure state; Promptly sterilize, the state when storing and transporting, when hole (5) rotate to (the spool half-twist shown in accompanying drawing 1, the accompanying drawing 2) when being connected the position with passage (4) with spool (2), this utility model is in complete opening state, two coyote holes are through it and UNICOM.Hole (5) two chamfers also remove corner angle, can not produce microgranule in the process of rotation, and the faying face of spool (2) and valve pocket (3) is the face of cylinder (or taper seat), because the material of valve pocket (3) is rubber (as butyl rubber) or plastic cement.Have good plasticity, spool face is extremely smooth, so they can also suitable rotation under the prerequisite of sealing.Faying face between valve seat (1) and the valve pocket (3) is the non-face of cylinder, and valve pocket (3) can also be gone up the location at valve seat (1) with valve seat (1) sealing, preferably is provided with multiple tracks bulge loop (7) on the valve pocket (3), and the sealing meeting between valve seat (1) and the valve pocket (3) is better.The opposite side that spool (2) is positioned at valve pocket (3) tape channel (4) has cannelure (8), and cannelure (8) one ends are close to this end face, and it radially intersects with blind hole (6), and the medicinal liquid in the medicated bag can be through this concentrated flow in blind hole (6), and medicinal liquid can flow to end fully automatically.Earlier spool (2) band awl end is inserted in the spool bore of valve pocket (3) during this utility model assembling, as previously mentioned because the material of valve pocket (3) is butyl rubber and so on, has better elastic and plasticity, impose certain normal pressure, spool can pass this hole and be positioned in the hole, then valve pocket (3) is pressed in the valve seat (1) together together with spool (2).

This utility model on the powder and liquid double-chamber transfusion bag of band medicine filling mouthpiece when using (as Fig. 4,5), it can and medicine filling mouthpiece (9) as one, the afterbody of interface is valve body (1), other structure and aforementioned in full accord.The double dot dash line of figure middle and lower part partly is a soft bag (9).In fact it also is a powder and liquid double-chamber bag, the inner chamber (11) of medicine filling mouthpiece (10) is solid chemicals (as powder) chamber, soft bag (9) is the water preparation chamber, (double dot dash line partly) has the composite cover (12) with its sealed attachment at the top of medicine filling mouthpiece (10), same requirement two Room in sterilization and transporting procedures are not connected, artificially valve is opened during use medicine is mixed in two coyote hole UNICOMs.

Satisfying the requirement that seals on the material and on the manufacturing process as valve seat (1) and spool (2), this utility model is made up of valve seat (1) and spool (2), on an end face of valve seat (1), passage (4) is arranged, the structure of spool (2) as hereinbefore, hole (5) on just axial communicates with the passage (4) on the valve seat (1), and two combine into one for spool and valve pocket.
