The metal ring has the functions of heating sterilization and impedance detection, and can objectively judge whether the absorption amount of the inoculation ring reaches a preset standard.

The utility model discloses a disposable convenient-to-carry canned fast food packaging box which comprises a packaging box body, a box base is arranged at the bottom end of the packaging box body, a juice box is placed in an inner cavity of the upper section of the packaging box body, and a bamboo stick containing groove is formed in the bottom wall of the juice box. A second box edge at the top end of the juice box is used in cooperation with a first box edge at the top end of the packaging box body, the packaging box body and the juice box are both of a conical structure design, containing scale marks are arranged on the outer wall of the juice box, instant skewers are placed in an inner cavity of the packaging box body, and the instant skewers are arranged in the inner cavity of the packaging box body. And the top ends of the bamboo sticks on the instant skewers extend into the bamboo stick storage grooves. The problems that the types of instant food in the current market are various, so that the types of canned instant food packaging boxes are various, however, according to the types of instant food, bamboo sticks have certain lengths, so that seals at the top ends of the packaging boxes are easily punctured, and instant food skewers in the packaging boxes are polluted are solved.

This utility model discloses a blow molding die for plastic bottles, relating to the field of blow molding die technology. The utility model includes a worktable, a movable component on the top of the worktable, a mold component on the top of the movable component, and a lifting component on the top of the worktable. The lifting end of the lifting component is equipped with an air blowing pipe and a clamping component, with the clamping end of the clamping component located outside the air blowing pipe. This utility model uses the lifting component to drive the air blowing pipe and the clamping component to move downwards synchronously. When the air blowing pipe reaches a predetermined position inside the plastic preform, the clamping component can clamp and seal the bottle opening of the plastic preform. This arrangement ensures that after the air blowing pipe transports gas into the plastic preform, the bottle opening of the plastic preform is less prone to expansion and deformation under the clamping force of the clamping component, while also preventing gas leakage, thus guaranteeing the blow molding effect of the plastic preform.

This utility model discloses an electric telescopic tool for hot water bag production. It relates to the field of hot water bags and aims to solve the problem that when the mold core is removed from the bag opening, the lack of air or even negative pressure inside the hot water bag leads to high friction between the mold core and the bag opening, making removal very difficult. The key technical point is that it includes a positioning cylinder and a telescopic cylinder. The telescopic cylinder is slidably positioned at one end of the positioning cylinder. A first fork is vertically arranged at the end of the positioning cylinder away from the telescopic cylinder, and a bent second fork is fixedly arranged at the end of the telescopic cylinder away from the positioning cylinder. The second fork is parallel to the first fork and fits against it. During the separation of the hot water bag, the tool achieves easy and effortless separation of the hot water bag and the mold core by disrupting the internal negative pressure environment and assisting in opening the bag opening.

The utility model relates to the technical field of batteries, and discloses a battery cell diaphragm hole scalding mechanism which not only can prevent a scalding needle from stabbing a diaphragm, but also can ensure the hole scalding effect. The battery cell diaphragm hole ironing mechanism comprises an ironing needle, a driving module and a heating module. The ironing needle comprises a connecting shaft and a plurality of hot ironing parts connected to the connecting shaft, the multiple hot ironing parts are evenly distributed in the circumferential direction of the connecting shaft, and a cylinder structure coaxial with the connecting shaft is defined by the multiple hot ironing parts. The driving module is connected to the blanching parts and used for driving the blanching parts to synchronously move relative to the connecting shaft in the radial direction of the connecting shaft so as to change the diameter of the cylinder structure defined by the multiple blanching parts. The heating module is used for heating all the hot ironing parts so as to change the temperature of the hot ironing parts.

The application provides a tracheal tube anti-falling device and relates to the technical field of medical devices.The tracheal tube anti-falling device comprises an anti-falling mounting piece, an inflation separation piece is fixedly installed on the anti-falling mounting piece, a guide air auxiliary piece is slidably inserted into the anti-falling mounting piece, a guide air anti-falling piece is installed on the anti-falling mounting piece and is attached to the guide air auxiliary piece, an anti-falling detection piece is fixedly installed on the anti-falling mounting piece, an alarm control piece is fixedly installed on the anti-falling mounting piece and is electrically connected with the anti-falling detection piece, and the anti-falling mounting piece is attached to the neck by means of adhesive paste, which is better than the traditional rope connection mode and does not cause a feeling of being confined.The attached rubber sheet can be slowly and simultaneously removed in an inflated manner, the tracheal tube is fixed by means of a rope winding around the neck in the current tracheal tube, the use comfort is poor, the tracheal tube is prone to loosening, the overall fit anti-falling detection structure is not provided, and the tracheal tube cannot be timely warned in the early stage of falling.

The invention provides an artificial blood vessel as well as a preparation method and application thereof. The artificial blood vessel is of a hollow cylindrical structure and is provided with an outer layer and an inner layer. The outer layer is made of gelatin and polyvinyl alcohol; the material of the inner layer comprises SA terminated polylactic acid, a polylactic acid-glycolic acid copolymer, polyethylene glycol and a hydroxyapatite sustained-release drug carrier; by controlling the material mechanical properties of the inner layer and the outer layer, the polytetrafluoroethylene needle head can pierce the outer layer material and cannot pierce the inner layer material, the direction of the needle head can be conveniently controlled during suturing, blood vessels are prevented from being pierced, and suturing is facilitated; meanwhile, the inner layer can gradually degrade and release drugs, the supporting performance is prolonged, and meanwhile the long-acting anti-inflammation and anti-coagulation effects are achieved.
