In specific implementation, when the sample 3 does not enter the sample chamber 111 through the sample inlet 121, the interior of the sample chamber 111 is communicated with the outside, and the inner wall of the sample chamber 111 has an antistatic effect, that is, the inner wall of the sample chamber 111 does not form an electrostatic magnetic force effect, and does not actively adsorb external dust and bacteria, and the inner wall of the sample chamber 111 has a sterilization effect, and can kill the bacteria adsorbed on the inner wall of the sample chamber 111, thereby ensuring the sanitation of the sample chamber 111 and avoiding pollution to the sample 3.

In the embodiment of the invention, the antistatic sterilization layer is composed of a plurality of nano metal mineral crystals, and the nano metal mineral crystals are tetrapod-like zinc oxide whiskers.

The tetrapod-like zinc oxide whisker is an antistatic high polymer material, and experiments prove that under the action of an electric field, the tip of the tetrapod-like zinc oxide whisker can generate an electric core concentration effect and a tunnel effect, so that the tetrapod-like zinc oxide whisker has a conductive characteristic and achieves an antistatic effect; in addition, under the condition of the same amount of the tetrapod-like zinc oxide whiskers, the resistance in the coating is lower than that in the plastic or rubber, so that the coating has better conductivity and achieves better antistatic effect, because: the tetrapod-like zinc oxide whiskers in the coating are hardly damaged and are completely and uniformly dispersed in the coating, and in the latter two cases, especially in rubber processing, because the material flowability is poor and the shearing force in the mixing process is also large, the tetrapod-like zinc oxide whiskers are partially damaged into single needles, even needle-like bodies are broken, and the formation of a conductive channel is influenced.

The outermost layer of the bacteria is synthesized with a layer of cell walls, and the cell walls of the bacteria are colorless, transparent, tough and elastic membrane walls and account for 10-40% of the total dry weight of the bacteria; due to refractivity and difficult dyeing; so that it is difficult to see under an optical microscope, and its main function is to maintain the appearance of bacteria and protect bacteria; most antibiotics, such as penicillin, inhibit peptidoglycan in bacterial cell walls, blocking the ability of microorganisms to build cell walls, thereby rendering the bacteria non-viable by losing their protective barrier. It is known that the purpose of sterilization can be achieved by inhibiting the synthesis of cell walls by bacteria or destroying the synthesized cell walls. The tetrapod-like zinc oxide whiskers in the crystals have four radial needle bodies, and the needle points have the capability of piercing the cell walls of bacteria through a nanocrystallization process, so that when the bacteria are adsorbed on the inner wall of the sample chamber 111, the needle points of the tetrapod-like zinc oxide whiskers can smoothly pierce the cell walls of the bacteria, the bacteria can die naturally due to the loss of a protective barrier, and the aim of sterilization is fulfilled.

In the embodiment of the invention, the liquid-repellent layer is a nano self-cleaning paint coating.

As is known, lotus leaves have strong self-cleaning capability because the lotus leaves have fine and uneven nano structures on the surfaces, and according to the principle, advanced technology is applied to form the concave-convex appearance similar to the lotus leaves on the surfaces of coatings in the drying and film-forming process of paints, so that the same self-cleaning capability is achieved; the technical development basis of the self-cleaning paint has a bionics principle, and the nano self-cleaning paint coating is made of a nano-structure material and a PIN technology, has strong surface tension, has strong hydrophobic capacity, can greatly increase the contact angle between water and the surface of the coating, and is beneficial to rolling off water drops on the surface of the coating.

In specific implementation, when the dc power supply is the semiconductor refrigeration sheet is powered on by dc power, the heat absorbing plate absorbs heat, that is, absorbs heat in the sample cavity 111 to keep cold the sample 3 in the sample cavity 111, and the heat dissipating plate emits heat, which is dissipated through the box body 11.

In addition, the main control chip 23 may be electrically connected to the dc power supply, and the main control chip 23 controls the voltage of the dc power supply, that is, controls the current intensity of the cold insulation circuit, so as to control the heat absorption and heat dissipation of the semiconductor refrigeration sheet, and maintain the temperature of the sample 3 at about 4 ℃, thereby prolonging the time for placing the blood gas sample in the sample 3.

It should be noted that the working principle of the semiconductor cooling plate is based on the peltier principle, and the effect was first discovered by j.a.c peltier in 1834, i.e. when the circuit composed of two different conductors a and B is energized with direct current, some other heat is released at the junction in addition to joule heat, while the other junction absorbs heat, and the phenomenon caused by peltier effect is reversible, and when the direction of the current is changed, the heat releasing and absorbing junction is changed, and the amount of heat absorbed and released is proportional to the current intensity ia and is related to the nature of the two conductors and the temperature of the hot end.
