Technical Field

[0001] The invention belongs to the field of medical packaging containers, and specifically relates to a ready-to-dispense double-ended needle large-capacity injection bottle. Background Art

[0002] When using clinical drugs, it is often necessary to mix sterile 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 or plastic ampoule, the traditional method is to inject a certain liquid into the powder injection bottle with a syringe, dissolve and dilute it, 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. It increases the workload of nurses while increasing the risk of aseptic operation, which brings great hidden dangers to drug safety. Summary of the invention

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] like Figure 1-12As shown, a ready-to-prepare double-ended needle large-capacity injection bottle comprises a support cylinder, a support tube, a sealing cover 1 and a large-capacity injection bottle 2, wherein the support tube is sleeved in the support cylinder, the lower end of the support cylinder is connected to the large-capacity injection bottle 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 middle silo 4 at the connection with the upper silo 3, the middle silo 4 is provided with a cylinder bottom with a circular hole, a baffle 7 and a clamping plate 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, the clamping plate 8 is located between the inner wall of the middle silo 4 and the circular hole, and the lower The silo 5 is provided with a rubber tube 9 and a connecting tube 10, and 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, and a block 15 with a tongue 14 and a stopper 16 are provided in the support tube, a clamping hole 17 is provided on the ring bottom 12, and a stopper hole 18 is provided at the connection between the ring bottom 12 and the outer ring 11 wall, the stopper 16 is obliquely arranged in the stopper hole 18 and the bottom is fixedly connected to the ring bottom 12, and a clamp 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 block 15, and the lower end of the tongue 14 is located on the inner side of the upper end of the clamping plate 8. A triangular protrusion 20 is provided on the outer wall of the outer ring 11 of the support tube. The rubber tube 9 is sleeved in the connecting tube 10, and the lower edge of the rubber tube 9 is shorter than the lower edge of the connecting tube 10.

[0031] There are three ways to connect the connecting tube 10 and the large-capacity injection bottle 2: threaded connection, welding structure or integral molding structure. When the threaded connection is adopted, the inner wall of the connecting tube 10 is provided with threads, and the large-capacity injection bottle 2 is threadedly connected with the connecting tube 10 by means of the threads. One end of the double-ended needle 13 is inserted into the rubber plug 22 or is located above the rubber plug 22.

[0032] A card 21 is provided on the inner wall of the lower silo 5; a sealing protrusion is provided on the inner wall of the card block 15 and the outer wall of the outer ring 11. A handle 23 is also provided on the support tube. The sealing cover 1 is covered on the upper opening of the support tube by means of glue or welding. The width of the card hole 17 is greater than the width of the card plate 8, and the width of the blocking hole 18 is greater than the width of the baffle 7.

[0033] In specific implementation, when the large-capacity injection bottle is in a sealed state without use, the bottom needle head of the double-ended needle 13 is inserted into the inside or upper part of the rubber plug 22 but the needle tip part is not exposed, and 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 medicine to be prepared into the support tube upside down, and the upper end needle of the double-ended needle 13 is inserted into the bottle 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 the 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 penetrates the rubber plug 22 at this time, and the needle tip is exposed in the large-capacity injection bottle 2; the solution in the large-capacity injection bottle 2 flows into the medicine bottle by flipping, and the powder or solution in the medicine bottle is completely dissolved and mixed and finally flows into the large-capacity injection bottle 2 after repeated flipping. 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 provided on the inner wall, and then the medicine bottle can be pulled out. The sealing effect of the rubber plug 22 prevents the liquid medicine from being polluted by air. When infusing, the large-capacity injection bottle can be hung up by the handle 23.
