The invention provides an automatic steam exhausting electric pressure cooker. The cooker comprises a cooker cover, a cooker inner container, a cooker body and a cantilever hinged with the cooker body, wherein the center of the cooker cover is rotationally pivoted to the cantilever; the cooker cover is rotationally buckled with or separated from the cooker body and provided with a counter weight pressure limiting valve; the cantilever is provided with an electromagnetic push rod; when the cooker cover is buckled with the cooker body, the electromagnetic push rod is close to the counter weight pressure limiting valve and can drive the counter weight pressure limiting valve to exhaust steam and release pressure; and when the cooker cover is separated from the cooker body, the electromagnetic push rod is far away from the counter weight pressure limiting valve. Compared with the prior art, the electric pressure cooker of the invention has the advantages of realizing automatic steam exhausting and pressure releasing through cooperating action of the electromagnetic push rod and the pressure limiting valve, ensuring that the cooker can only be opened under the condition that foods are boiled completely, eliminating the safety potential hazard of user scalding, further expanding application range and saving cost, along with simpler structure, more convenient installation and no occupation of internal space.

The invention relates to a self-adaption continuous infusion apparatus. The self-adaption continuous infusion apparatus comprises an upper half part and a lower half part, and is characterized in that the upper half part is provided with a bottle plug puncture device (2) and a bottle plug puncture device protection cover, the upper end of the bottle plug puncture device (2) is used for puncturing through a bottle plug of a to-be-infused bottle, and the bottle plug puncture device protection cover is fixedly arranged on the bottle plug puncture device (2) to protect the bottle plug puncture device (2). In the self-adaption continuous infusion apparatus, the situations are avoided that infusion is automatically stopped after infusion is completed, the blood return phenomenon is caused when nurses do not attend on patients timely and the liquid level drops to a too low level, more seriously, gas enters the human body, which results in bad results like aeroembolism, or when multiple infusion bottles are infused continuously, if the liquid level is lower than the lower part of a Murphy's dropper, air exhaust needs to be conducted again or intravenous injection needs to be conducted again; meanwhile, to prevent the situation that the liquid level is lower than the Murphy's dropper, the nurses, patients and relatives need to conduct nursing in real time, which results in unnecessary tension and psychological burdens of the three parties, therefore, the psychological burden in seeking medical service can be sharply lowered through automatic stopping of infusion, and thus the comfort in seeking medical service is improved.

The invention relates to a self-venting bubble-free infusion set, which comprises a body comprising a venting tube connected with a lower catheter and a buffer body arranged in a dipper. The upper and lower ends of the venting tube are communicated; at least one venting groove is formed on a middle part of a side wall of the venting tube; the upper part of the venting tube is connected with the buffer body; the buffer body comprises a buffer surface and a handle connected with the buffer surface, wherein the handle has a hollow structure and is sealed on a part close to the buffer surface; and a circular air vent is formed at the lower end of the handle close to the sealed part. The self-venting bubble-free infusion set has the advantages that: automatic venting is realized through only one bottle inserting action during infusion, bubbles are not generated, and the infusion set is easy to operate and safe and reliable.
