Description

Liquid-based cell preservation bottle

Technical Field

The utility model belongs to the technical field of medical equipment, and in particular relates to a liquid-based cell preservation bottle.

Background Art

Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. Medical devices include medical equipment and medical consumables, such as cell preservation bottles used in the cell testing process. Cell preservation bottles are a type of preservation bottle used to preserve preservation fluid. Cell preservation bottles in the prior art usually include a bottle body and a bottle cap. The bottle cap is threadedly connected to the bottle mouth of the bottle body. After the bottle cap is tightened, it is sealed and fixedly connected to the bottle mouth. The sampling brush head containing the cell sample is placed in the bottle for preservation.

Chinese utility model patent CN219578161 U discloses a cervical liquid-based cell preservation bottle that is convenient for adding samples. The device includes: a preservation bottle body, a preservation cover is arranged on the top of the preservation bottle body, a liquid collecting funnel is arranged at the bottom of the inner cavity of the preservation bottle body, the preservation cover includes a cover plate, a sealing plug and a pull ring, two pull rings are arranged, and the edge of the pull ring ring is chamfered. By arranging the cover plate, the sealing plug and the pull ring, it is convenient for the staff to pull the pull ring to drive the sealing plug on the cover plate to separate from the bottle mouth of the preservation bottle body, so that the staff can quickly seal and sample the preservation bottle body.

In the above technical solution, the sealing plug is directly inserted into the inner cavity of the preservation bottle. During the movement and preservation of the preservation bottle by the staff, the cell sample will adhere to the sealing plug after vibration. When the pull ring is pulled to remove the sealing plug, the cell base fluid will splash onto the staff or the operating area, thus causing certain risks.

Utility Model Content

The purpose of the utility model is to provide a liquid-based cell preservation bottle in view of the above-mentioned technical problems, so as to avoid the cell-based liquid from splashing onto the staff or the operation area when the staff opens the preservation bottle to sample the cell sample in the preservation bottle, thereby preventing certain risks.

In view of this, the utility model provides a liquid-based cell preservation bottle, comprising: a preservation bottle body, a bottle cap is threadedly connected to the top of the preservation bottle body, and the bottle cap comprises:

A cover body, wherein the inner wall of the cover body is provided with an internal thread, and a film is provided within the cover body;

A flip cover, the flip cover is movably connected to the cover body through a movable member;

Wherein, the film is located above the internal thread.

In the present technical solution, after the sampling brush head containing the cell sample is placed in the bottle, the bottle cap is tightened onto the upper end of the preservation bottle body, and the flip cover is movably connected to the cover body through a movable part, so that the staff can take samples without removing the cover body. When the staff needs to take samples, the flip cover is opened. Due to the obstruction of the film, the cell base fluid will not be directly contacted to avoid splashing. The liquid extraction tube is inserted through the film to enter the preservation bottle body for sampling, thereby preventing the cell base fluid from splashing onto the staff or the operation area, reducing potential risks.

In the above technical solution, further, the movable part includes:

A pull ring, which is arranged at the upper end of the flip cover;

A first magnetic strip, wherein the first magnetic strip is disposed on a side wall of the flip cover;

a second magnetic strip, wherein the second magnetic strip is disposed on a side wall of the cover;

Wherein, the first magnetic stripe is adapted to the second magnetic stripe.

In the technical solution, the flip cover is movably connected to the cover body through the pull ring, the first magnetic strip, and the second magnetic strip. This magnetic connection allows the flip cover to be easily opened and closed while maintaining its tight connection with the cover body.

In the above technical solution, further, the edges of the first magnetic stripe and the second magnetic stripe are chamfered.

In the above technical solution, further, two pull rings are provided, and the edges of the pull ring openings are chamfered.

In the technical solution, the edges of the first magnetic strip and the second magnetic strip are chamfered and the edge of the pull ring opening is chamfered to avoid injuries to the hands of the staff.

In the above technical solution, further, a connecting strip is provided on the side wall of the flip cover away from the first magnetic strip, and the other end of the connecting strip is fixedly connected to the side wall of the cover body.

In the technical solution, under the effect of the connecting strip, it is prevented that the staff randomly puts the flip cover when it is opened, which may cause the flip cover to be lost and cause unnecessary trouble.

In the above technical solution, further, the film is made of rubber material, and a cross-shaped groove is provided in the center of the film.

In the technical solution, a cross-shaped groove is provided in the center of the film to facilitate the staff to penetrate the film through the liquid extraction tube to take samples.

In the above technical solution, further, a funnel-shaped collecting bin is provided at the inner bottom of the storage bottle body.

In the above technical solution, further, a filter screen is arranged in the body of the preservation bottle, a sampling tube is arranged at the center of the filter screen, and the lower end of the sampling tube is connected to the collection bin.

In the present technical solution, the cell sample entering the collection chamber is filtered through a filter, thereby preventing mucus, leucorrhea and other interfering components that affect diagnosis from entering the collection chamber.

In the above technical solution, further, a placement cavity for placing the sampling brush is formed between the outer wall of the sampling tube and the inner wall of the preservation bottle body.

In the above technical solution, further, when the preservation bottle body and the bottle cap are tightened, the top end of the sampling tube is in contact with the film.

In the present technical solution, the staff penetrates the film through the liquid extraction tube and enters the collection bin through the liquid extraction tube to sample the cell sample. When the preservation bottle body and the bottle cap are tightened, the top end of the sampling tube fits against the film to prevent impurities from entering the collection bin from the top end of the sampling tube due to the overturning of the preservation bottle body, thereby improving the accuracy of cell detection.

The beneficial effects of the utility model are:

1. After placing the sampling brush head containing the cell sample into the bottle, tighten the bottle cap to the upper end of the preservation bottle body. The flip cover is movably connected to the cover body through a movable part, which is convenient for the staff to take samples without removing the cover body. When the staff needs to take samples, the flip cover is opened. Due to the obstruction of the film, there will be no direct contact with the cell base fluid, thereby avoiding splashing. The liquid extraction tube is inserted through the film into the preservation bottle body for sampling, thereby avoiding the cell base fluid from splashing onto the staff or the operation area, reducing potential risks.

2. The staff passes the liquid extraction tube through the film and enters the collection chamber to sample the cell sample. When the preservation bottle body and the bottle cap are tightened, the top of the sampling tube fits the film to prevent impurities from entering the collection chamber from the top of the sampling tube due to the overturning of the preservation bottle body, thereby improving the accuracy of cell detection.
