Description

Technical Field

[0001] The utility model relates to the field of pharmaceutical preparation packaging, in particular to a vial for freeze-dried powder for injection. Background Art

[0002] Clinically, vials are commonly used to contain powder preparations or liquid preparations. When used to contain powder preparations (such as cytarabine for injection), during use, a certain amount of liquid (diluent for dissolving the powder) needs to be sucked with a syringe, and then the needle of the syringe is passed through the rubber stopper of the vial, and the liquid is injected into it. After fully shaking and dissolving, it is sucked out again. Since vials are generally small, their rubber stoppers are also small. When using a syringe, the situation where the needle tip stabs the operator may occur due to the needle tip not being aligned, causing certain danger.

[0003] Ordinary vials are generally sealed with rubber stoppers. When the syringe needle pierces the rubber stopper, it is easy to bring rubber particles of the bottle cap into the vial, resulting in rubber stopper particle contamination.

[0004] Chinese Patent CN218247825U discloses a vial that does not require a needle, including a bottle body and a sealing member for sealing the bottle body; the sealing member includes a sealing plug inserted into the bottle mouth part of the bottle body, a sealing cover sleeved on the bottle mouth part, an intubation tube arranged at the end far from the bottle body inside the sealing cover, a conical plug arranged at the end of the intubation tube close to the bottle body, a first groove arranged at one end of the sealing plug close to the intubation tube, and a protective sleeve sleeved on the outer wall of the sealing plug; the sealing cover is provided with a through hole, the through hole is communicated with the intubation tube, the intubation tube and the plug are both arranged in the first groove, and there is a gap between the sealing plug and the sealing cover. This vial that does not require a needle can suck or inject liquid into the vial without using a needle, which is safer.

[0005] During the use of the above-mentioned utility model, the conical plug needs to pierce the rubber stopper, and there is still a possibility of rubber particle contamination. In addition, the end of the intubation tube passes through the sealing plug and enters the vial. When sucking the liquid medicine out with a syringe, inevitably, there will be a certain amount of liquid medicine remaining in the bottle, resulting in waste of the medicine and reduction of the dosage used.

[0006] Therefore, it is necessary to design a new type of vial that can complete liquid preparation without using a needle, and can also ensure that all the liquid medicine in the bottle can be sucked out and the liquid medicine is not contaminated by rubber particles. Content of the Utility Model

[0007] In order to solve the problems that the liquid medicine in the vial in the prior art is easily contaminated by rubber particles and the liquid medicine cannot be all sucked out, the utility model provides a vial for freeze-dried powder that can suck out all the liquid medicine and avoid rubber particle contamination;

[0008] The utility model provides a vial for freeze-dried powder for injection, which adopts the following technical scheme:

[0009] A vial for freeze-dried powder for injection, comprising a bottle body, an outer cap and an inner cap. An injection hole and a sealing cap are provided on the inner cap. The injection hole has the same shape as the syringe nipple, which is a tapered hole that is wider at the top and slightly narrower at the bottom. A circle of shielding strips is fixedly connected to the bottom of the injection hole to prevent the syringe nipple from extending into the vial; the connecting arm of the sealing cap is fixedly connected to the edge of the inner cap, and the sealing cap can be buckled into the injection hole to seal the injection hole.

[0010] Preferably, a groove is further provided on the inner cap, and the connecting arm of the sealing cap has the same shape and thickness as the groove and can be pressed into the groove.

[0011] Preferably, the inner surface of the top of the inner cap is an inclined surface structure, and the included angle between the inclined surface and the horizontal is θ, where θ > 0°.

[0012] Preferably, an anti-slip layer is provided on the inner wall of the injection hole to ensure that the syringe nipple part can be closely attached to the injection hole and no liquid leakage will occur.

[0013] Preferably, a tear strip is provided on the outer cap, and a buckle and a buckle groove are provided at the starting end of the tear strip. The buckle can be buckled into the buckle groove.

[0014] Preferably, a non-slip sleeve is provided in a circle below the shoulder on the upper half of the bottle body, and anti-slip ridges are provided on the non-slip sleeve.

[0015] More preferably, the width of the non-slip sleeve is 1-2 cm.

[0016] Preferably, the diameter of the circular hole formed by the shielding strip is larger than the inner diameter of the syringe nipple part.

[0017] Preferably, the inner cap is made of plastic material, and the outer cap is made of aluminum foil material.

[0018] In summary, the beneficial effects of the utility model are as follows:

[0019] With the injection hole and the sealing cap provided on the inner cap of the utility model, medical staff can use a needleless syringe to dilute the freeze-dried powder and suck out the liquid medicine, which can effectively avoid the situation of medical staff being accidentally injured by the needle. The utility model does not need to penetrate the rubber stopper, and can effectively avoid the pollution of rubber particles.

[0020] By providing a shielding strip at the bottom of the inner cap of the utility model, it can be avoided that the syringe nipple part extends into the vial, resulting in incomplete suction of the liquid medicine. The inner surface of the top of the inner cap is set as an inclined surface structure, which can make the liquid medicine concentrate at the injection hole when sucking the liquid medicine, which is beneficial to sucking out all the liquid medicine.

[0021] The utility model is provided with an anti-slip sleeve on the bottle body, which is convenient for medical staff to grip and reduces the risk of the vial slipping. Description of the Drawings

[0030] As Figure 2 , Figure 3 and Figure 5As shown, the inner cap 3 is provided with an injection hole 31, a sealing cap 32 and a groove 33. The injection hole 31 is a conical hole that is wider at the top and slightly narrower at the bottom. At the bottom of the injection hole, a shielding strip 311 is integrally formed. The shielding strip 311 can prevent the nipple part of the syringe from extending into the inside of the vial, preventing some of the liquid medicine from not being sucked out when sucking the liquid medicine. The inner wall of the injection hole 31 is provided with a rubber anti-slip layer, which can make the nipple part of the syringe fit tightly with the injection hole 31 to prevent liquid leakage. The inner surface of the top of the inner cap 3 is arranged as an inclined surface structure, and the angle between the inclined surface and the horizontal is θ, where θ > 0°, ensuring that all the liquid medicine is concentrated at the injection hole 31 when sucking the liquid medicine, so as to ensure that medical staff can suck out all the liquid medicine in the vial at one time.

[0031] The implementation principle of the embodiment of the present utility model is as follows:

[0032] During use, medical staff unclips the buckle 42 on the aluminum foil outer cap from the buckle groove 43, tears off the easy-to-tear strip 41 with force, and removes part of the aluminum foil outer cap 4. Medical staff unclips the sealing cap 32 by hand. One hand holds the syringe without a needle, and the other hand holds the anti-slip sleeve 2 part of the vial. The nipple part of the syringe is inserted into the injection hole 31 on the inner cap 3. The injection hole 31 and the nipple part of the syringe fit tightly. The nipple part of the syringe is inserted until it abuts against the shielding strip 311.
