Problems solved by technology

When the surgical specimens are placed in the specimen container, the formaldehyde solution is easy to volatilize and leak, causing damage to the health of the operator; at the same time, due to the volatilization of the formaldehyde solution, the concentration of the specimen fixative solution will also decrease, resulting in the specimen soaking The concentration of the solution is not up to standard, which eventually leads to the denaturation of the specimen

Embodiment 1

[0030] In this embodiment, when the operator removes a small piece of pathological specimen from the patient's body and needs to put it into the specimen bottle and pour 30ml of formaldehyde solution into it for disinfection, only one bottle of 30ml formaldehyde solution is needed, and the conventional structure of the formaldehyde solution bottle is a bottle body The mouth is heat-sealed with aluminum foil, and the outside of the bottle mouth is processed with external threads. In order not to leak when pouring formaldehyde solution, you can use such as Figure 1-3 The formaldehyde-leakage proof specimen container shown includes a container body 1 , an injection pipe 2 , a limiting ring 3 , an upper tooth set 4 , a limiting half ring 7 and a tear handle 71 .

[0031] In this embodiment, the container body 1 can be an ordinary specimen bottle for containing small specimens, and the mouth of the specimen bottle has an external thread. The injection pipe 2 is injection molded f...

Embodiment 2

[0038] When the operator removes a large pathological specimen from the patient's body, in order to save costs, a plastic specimen bag with a large volume is often used. When the specimen bag needs to be placed in the formaldehyde solution for disinfection, multiple bottles of formaldehyde solution will be required. In the past, during the process of pouring the formaldehyde solution into the specimen bag, the specimen bag was open, and the formaldehyde would leak into the air environment. Take pouring 1500ml formaldehyde solution as an example, in order not to leak when pouring formaldehyde solution, you can use the following Figure 4-7 The formaldehyde-leakage prevention specimen container shown includes a container body 1 , an injection pipe 2 , a casing sleeve 6 , a stop ring 3 , an upper tooth set 4 and a lower tooth set 5 . In this embodiment, the container body 1 is a specimen bag, and three bottles of formaldehyde solution are required, so the number of injection pipe...

Abstract

The invention relates to the field of medical appliances and particularly relates to a specimen container for preventing formaldehyde from leaking. The specimen container is communicated with at leastone injection pipeline capable of injecting a formaldehyde solution into a container body, the injection pipeline is internally provided with a limiting ring, the limiting ring is provided with a liquid injection hole for allowing the formaldehyde solution to go through, and an upper tooth group capable of puncturing an aluminum foil film on a bottleneck of a formaldehyde solution bottle is arranged on the upper end face of the limiting ring. Due to the design of the injection pipeline and the limiting ring, the formaldehyde solution poured into the container body avoids volatilizing to endanger the human body, and the concentration of the formaldehyde solution is guaranteed to be not changed.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a formaldehyde leakage-proof specimen container. Background technique [0002] Formalin (formalin) is a 37% to 40% formaldehyde solution, which is flammable, highly corrosive, and highly irritating. It is an important disinfectant and preservative, and it is also a class of carcinogens. It is often used to fix biological specimens and preserve corpses. and anti-corrosion, etc., but it has a strong stimulating effect on the skin, eyes and mucous membranes, and has an inhibitory effect on the central nervous system after absorption. Formaldehyde is oxidized in the body to form formic acid, which often leads to acidosis, that is, formalin poisoning. [0003] In surgery, specimen management is particularly important. With the increase of tumor patients, the number of pathological specimens is gradually increasing, and surgical specimens are required to be soaked in formaldehyde sol...
