Description

Technical Field

[0001] The invention belongs to the field of pharmaceutical packaging containers, and specifically relates to a large-capacity injection container which is safe, convenient for liquid preparation and has no residue. Background Art

[0002] When using clinical drugs, it is often necessary to mix powder injection drugs or small-volume injections with large-volume injection bottles before injection. Especially when the dosage form to be prepared is sterile powder injection for injection, the traditional method is to inject a certain liquid into the powder injection bottle with a syringe, dissolve and dilute it, and then use a syringe to extract the mixed liquid in the powder injection bottle, and finally inject it into the large-volume injection bottle. The traditional method not only has cumbersome operating steps, but also easily causes cross infection or environmental pollution during the complex operation process, which increases the workload of nurses and increases the risk of aseptic operation, bringing great hidden dangers to drug safety. In addition, when the existing injection container is infused to the end, there is often some residual liquid at the bottle mouth that cannot flow out. When the drug is a special drug or requires precise administration, the residual liquid often affects the patient's treatment effect, causing waste of precious drugs and deviation of the dosage.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] like Figure 1-14 As shown, a large-capacity injection container that is safe, convenient for liquid preparation, and has no residue includes an upper cover, a container body 2, and a lower cover; the upper cover and the lower cover are respectively sealed with the container body 2, the upper cover is a double-ended needle cover, and the lower cover is a plug-in cover.

[0034] The double-ended needle cover comprises a support cylinder, a support tube, and a sealing cover 1. The support tube is sleeved in the support cylinder, the lower end of the support cylinder is connected to the container body 2, and the sealing cover 1 covers the upper opening of the support cylinder; the support cylinder comprises an upper silo 3, a middle silo 4 and a lower silo 5. The outer diameter of the middle silo 4 is the same as the inner diameter of the upper silo 3. A protrusion 6 is provided on the inner wall of the connection between the middle silo 4 and the upper silo 3. The middle silo 4 is provided with a cylinder bottom with three circular holes, and three groups of baffles 7 and three clamping plates 8 are provided on the cylinder bottom. One side wall of the baffle 7 is fixedly connected to the inner wall of the middle silo 4, and the clamping plate 8 is located between the inner wall of the middle silo 4 and the circular hole. A rubber cylinder 9 and a connecting cylinder are provided in the lower silo 5. 10. A rubber plug 22 is provided in the rubber tube 9; the support tube includes an outer ring 11, a ring bottom 12 and a double-ended needle 13; three blocks 15 with latches 14 and three stoppers 16 are provided in the support tube; three latch holes 17 are provided on the ring bottom 12; three stopper holes 18 are provided at the connection between the ring bottom 12 and the wall of the outer ring 11; the stopper 16 is obliquely arranged in the stopper hole 18 and the bottom is fixedly connected to the ring bottom 12; a clamping head 19 is provided on the upper part of the stopper 16; the double-ended needle 13 is located at the center of the support tube and is fixedly connected to the ring bottom 12; the upper edge of the clamping plate 8 passes through the clamping hole 17 and corresponds to the lower edge of the middle part of the clamping block 15; and the lower end of the latching tongue 14 is located on the inner side of the upper end of the clamping plate 8. The outer wall of the support tube outer ring 11 is provided with a plurality of triangular protrusions 20; the rubber tube 9 is sleeved in the connecting tube 10, the lower edge of the rubber tube 9 is shorter than the lower edge of the connecting tube 10, and the outer diameter of the middle silo 4 is greater than the outer diameter of the lower silo 5. The double-ended needle cover is threadedly connected or welded to the container body 2. The inner wall of the connecting tube 10 is provided with threads, and the container body 2 is threadedly connected to the connecting tube 10 by means of the threads.

[0035] The plug-in cover includes a fixing ring 21, a conical bucket 24 and a cylindrical mouth 25 from top to bottom. The fixing ring 21, the conical bucket 24 and the cylindrical mouth 25 are an integrally formed structure. The lower end of the cylindrical mouth 25 is sealed. The plug-in cover is welded or integrally formed with the container body 2. One end of the double-ended needle 13 is inserted into the rubber plug 22 or located above the rubber plug 22; a handle 23 is also provided on the support tube. The inner wall of the block 15 and the outer wall of the outer ring 11 are both provided with sealing protrusions. The width of the clamping hole 17 is greater than the width of the clamping plate 8, and the width of the blocking hole 18 is greater than the width of the baffle 7. The sealing cover 1 is covered on the upper mouth of the support tube by means of glue or welding. The plug-in cover is also provided with a base 26, which is sleeved on the fixing ring 21, and the base 26 is a conical seat or a cylindrical seat.

[0036] In specific implementation, a large-capacity injection container is provided which is safe, convenient for liquid preparation and has no residue. The upper cover is a double-ended needle cover. When the container is in a sealed state without use, the bottom needle head of the double-ended needle 13 is located inside or on the upper part of the rubber plug 22 but the needle tip is not exposed. The upper edge of the clamping plate 8 passes through the clamping hole 17 and is opposite to the lower edge of the middle part of the clamping block 15, that is, the clamping plate 8 limits the position of the support tube so that it can no longer move downward or left and right. When in use, tear open the sealing cover 1, insert the medicine bottle containing the reagent to be prepared into the support tube upside down, and the upper end needle of the double-ended needle 13 is inserted into the rubber stopper of the medicine bottle. At the same time, due to the thrust of the bottle mouth on the latch tongue 14, the latch tongue 14 pushes the card plate 8 outward, and the upper edge of the card plate 8 is located on the outer side of the outer wall of the card block 15, which loses its limiting effect and provides space for the support tube to move downward. The medicine bottle is gently pushed downward, and the support tube begins to move downward; when the support tube moves to the bottom of the middle silo 4, under the action of the baffle 7, the upper end of the block 16 is squeezed inward, and the card head 19 clamps the bottleneck of the medicine bottle, which is firm and safe. The lower end needle of the double-ended needle 13 now penetrates the rubber stopper 22, and the needle tip is exposed in the container body 2; flipping allows the solution in the container body 2 to flow into the medicine bottle, and repeated flipping allows the powder or solution in the medicine bottle to be completely dissolved and mixed and finally flow into the container body 2. Finally, lift the medicine bottle up, and after the support tube is reset, the support tube is prevented from being pulled out due to the limitation of the triangular protrusion 20 and the protrusion 6 on the inner wall, and then the medicine bottle can be pulled out. The sealing effect of the rubber plug 22 prevents air contamination. When infusing, the container body can be hung up by the handle 23.

[0037] The lower cover is a plug-in cover. When in use, the base 26 is unplugged, and the cylindrical opening 25 can be used to plug and unplug the injection needle. The conical bucket 24 can make all the liquid medicine in the container flow into the cylindrical opening 25. Finally, all the liquid medicine flows into the injection needle and then is administered to the patient, so that there is no residual liquid medicine, the measurement is more accurate, there is no waste, and the expected treatment effect is achieved.
