Sensor for blood component analysis

A sensor for blood component analysis, which allows even a trace amount of blood to be led to an analysis portion reliably. The sensor for blood component analysis includes a substrate, a spacer, and a cover. The cover is disposed on the substrate with the spacer intervening between the cover and the substrate, whereby a space that serves as an analysis portion and a channel for leading blood to the analysis portion is formed inside the sensor. Through holes are formed in the substrate and the spacer, respectively, so that a common through hole through which a needle of a lancet can pass is formed when the spacer is disposed on the substrate. The through hole of the spacer communicates with the channel and a top of the through hole of the spacer is covered with the cover, whereby a lancing portion is formed by the common through hole and a portion of the cover covering the top of the through hole of the spacer. In use, the sensor is placed at a position where blood collection is to be performed, the portion of the cover covering the lancing portion is broken through with the needle of the lancet so that the needle is allowed to pass through the common through hole to puncture the position, and blood that has come out is guided by a downwardly protruding burr formed when the cover is broken through so that the blood is led to the channel and flows through the channel to be led to the analysis portion.

Medicinal gelatin microspheres and preparation method thereof

ActiveCN102475684AMeet the needs of delayed release and prolonged efficacyImprove efficacyOrganic active ingredientsPharmaceutical product form changeCross-linkDissolution
The invention relates to medicinal gelatin microspheres and a preparation method thereof, and belongs to the field of medicine preparation. The active ingredient of the medicinal gelatin microspheres is trimetazidine or a medicinal salt of the trimetazidine. The preparation of the microspheres adopts a chemical cross-linking method, and comprises steps of emulsification, deoiling and dewatering, chemical cross-linking, washing and drying, and the like. According to the preparation method, the particle size, the appearance, the encapsulation efficiency, the drug loading rate are adopted as indexes to comprehensively optimize the carrier, the oil phase, the dewatering and deoiling agent, the cross-linking curing agent, and other reagents added in the process, wherein the carrier, the oil phase, the dewatering and deoiling agent, the cross-linking curing agent, and other reagents are suitable for preparation of the microspheres of the present invention. The prepared microspheres have characteristics of smooth surface, particle size of 50-200 mum, drug loading rate of 30-35%, and has a slow release effect under the common dissolution conditions. In addition, the blood drug level of the microspheres is stable in vivo, and is better than the blood drug level of ordinary tablets.

Inflatable double-opened-blade protection type puncturing device for thoracoscope

The invention discloses an inflatable double-opened-blade protection type puncturing device for a thoracoscope. The inflatable double-opened-blade protection type puncturing device comprises a hollow tube pipe; a pair of clamping arms rotating around a fixed shaft and an airbag mechanism for driving the clamping arms to clamp a thoracoscope lens are arranged at the end part of the hollow pipe body; each clamping arm consists of a long movable blade and a short movable blade; air cavity bags are arranged on the inner lateral faces of the long movable blades and the short movable blades and the surface of the end part of the hollow pipe body; and when the air cavity bags are full of gas, the long movable blades and the short movable blades rotate around the fixing shaft to an expansion state until the long movable blades and the short movable blades are compactly connected with the thoracoscope lens at the bottom of the hollow pipe body. The double-opened movable blades lead bloods at a cut position well, so that the pollution on the thoracoscope lens can be reduced. The airbags at the end parts of the hollow pipe body are prevented from being damaged on intercostals nervus vascularis and the like through the design; and meanwhile, the inflatable double-opened-blade protection type puncturing device has certain effects of hemostasis by compression on the cut. Furthermore, the airbags at the inner sides of the double-opened movable blades form a protection cushion to buffer the upper turning shape of the thoracoscope lens. Therefore, the inner side of the chest wall can be prevented from being damaged.

Processing method of scrap blood and apparatus

The invention discloses a processing method and an equipment of blood which is discarded. Because of the specificity of the blood processing of a blood station, an ordinary disinfection cabinet cannot meet the disinfection requirement of the blood station, all along the blood station adopts the traditional disinfection way to disinfect, thus the dangers that the disinfection is incomplete, the environment is polluted, and the related personnel who contact with the blood is infected exist. The invention leads blood bags which are required to be processed and provided with pathogenic microorganisms to be arranged in the cabinet which is equipped with a quartz heating tube, an ultraviolet ray disinfection lamp and an ozone generator, under the conditions that the ozone concentration is more than 40 mg/l, and the 253.7 nm ultraviolet intensity radiated by the ultraviolet ray disinfection lamp is more than 140 microwatt/cm<2>, the blood bags are sterilized for 60 to 100 minutes under the temperature of 75 to 90 DEG C. The method not only can thoroughly kill the pathogenic microorganisms outside and inside the blood bags and lead the blood in the blood bags to be congealed into block shape, but also can ensure that the blood bags are not broken in the sterilization process, guarantee the healthy safety of the related personnel, and sever the propagation spread possibility of the contagious diseases through the blood which is discarded.
