The invention concerns hypoxia, which is a critical medical condition that can have severe health consequences. Early and accurate detection of hypoxia is thus desirable to prevent irreversible tissue damage and improve clinical outcomes. Traditional methods for detecting hypoxia, such as arterial blood gas measurements, use of oxygen sensors or misonidazole positron-emitting tomography, have limitations in terms of accuracy, invasiness, irradiation and cost. That is why the inventors have developed a method to determined a biological state linked to hypoxia, said method being without irradiation.

The invention belongs to the field of respiratory and cardiovascular system disease treatment, and provides application of bletilla striata glycoside in preparation of a medicine for treating or preventing heart failure and pulmonary edema. It is found and proved for the first time that bletilla striata glycoside can remarkably improve heart function indexes of heart failure model mice, relieve pathological injuries of heart and lung tissue, effectively regulate and control arterial blood-gas indexes in a pulmonary edema model, reduce the level of inflammatory factors in alveolar lavage fluid and improve the pathological structure of lung tissue. The medicine can be applied in dosage forms such as oral administration, injection or spray, and the preferable dosage is 2.5-10 mg / kg. The invention provides a multi-target and multi-effect intervention strategy derived from a natural product for heart failure and concurrent or secondary pulmonary edema thereof, and has a remarkable clinical transformation prospect.

The utility model relates to the technical field of medical instruments, in particular to a high-reliability exhaust type preset arterial blood gas needle which comprises a piston, a core rod, a sleeve, an exhaust plug and a needle head, the piston is arranged on the inner side of the sleeve in a sliding mode, the core rod is coaxially fixed to the end, close to an opening of the sleeve, of the piston, and a ventilation channel is formed in the piston. One end, far away from the opening of the sleeve, of the ventilation channel is filled with the venting plug, the inner side of the ventilation channel is filled with the non-return plug, the non-return plug and the venting plug are arranged in a spaced mode, the edge of the end, far away from the opening of the sleeve, of the piston is provided with a ventilation hole, the ventilation hole is communicated with the ventilation channel between the non-return plug and the venting plug, and both the venting plug and the non-return plug are ventilated without liquid. The needle is mounted at one end of the sleeve away from the opening. According to the blood gas needle, the vent holes are formed in the edge of the piston, so that bubbles which cannot be discharged can be prevented from being easily formed at dead corners between the piston and the inner wall of the sleeve when arterial blood is filled to be close to the piston, and the blood gas needle has a good application prospect.

The utility model discloses an arterial blood gas needle capable of mutually converting preset blood drawing and direct blood drawing, which comprises a needle cylinder and a piston rod movably arranged in the needle cylinder, a blood drawing cavity is arranged in the needle cylinder, the piston rod slides along the inner wall of the needle cylinder in the blood drawing cavity, and the arterial blood gas needle further comprises a sealing cap used for converting preset blood drawing into direct blood drawing. And the sealing cap is detachably arranged at the top end of the piston rod, and is detachably arranged at the front end of the needle cylinder during inspection. The preset type blood gas needle is reasonable in structural design, aiming at some special patient groups such as infants and elderly patients, when blood vessel pressure in bodies of the patients is not enough to press enough blood into the needle cylinder, the sealing cap can be inserted into the top of the needle cylinder to play a sealing role and generate vacuum negative pressure, and the preset type blood gas needle is converted into a direct pumping type. The patient continues to be subjected to blood drawing in the mode of manually drawing the piston rod, and the insufficient amount of blood in the needle cylinder during preset blood drawing is supplemented.

The present application relates to the technical field of medical devices, and particularly relates to a radial artery arteriole blood gas puncture fixing device. The radial artery arteriole blood gas puncture fixing device comprises a mounting frame, a notch is formed in the mounting frame, a bandage is symmetrically mounted on two sides of the mounting frame, a rotating cover plate is rotatably connected to the mounting frame, a control panel is mounted on the rotating cover plate, a universal coupling is symmetrically rotatably mounted on the inner wall of the mounting frame, a mounting plate is rotatably mounted on the end of the universal coupling, and a guide tube is connected to the mounting plate. The universal coupling and the mounting plate are arranged, so that the guide tube can be freely adjusted in angle and position in three-dimensional space, can be fitted to the actual bending trend of the radial artery in three-dimensional space, and can solve the problem that the prior art can only adjust the angle in a single plane. When operating, the angle of the mounting plate and the guide tube is flexibly adjusted through the universal coupling, the universal joint is locked by an electromagnet after the position is determined, so as to fix the guide tube. The structure enables the puncture needle to be inserted along the real track of the blood vessel.

The application discloses an extracorporeal organ perfusion system, which comprises a perfusion main loop and an inflammation factor removing sub-loop; the perfusion main loop comprises a sterile organ storage container, a venous blood gas monitoring device, a venous pressure monitoring device, a perfusion liquid storage tank, a main loop pump, a heat exchanger, a gas exchanger, a white blood cell filter, a bubble filter, an arterial pressure monitoring device, a flow monitoring device, a temperature monitoring device, an arterial blood gas monitoring device and a biological sensor which are sequentially connected and form a circulation loop; the inflammation factor removing sub-loop comprises a purification sub-loop input pump, an inflammation factor filter, a perfusion exchange liquid storage tank and a purification sub-loop output pump which are sequentially connected; the output end of the purification sub-loop output pump is in communication with the input end of the perfusion liquid storage tank; the application has the advantages that the inflammation factors in the perfusion loop can be effectively removed, the perfusion liquid can be effectively reused, and various physiological parameter indexes in the perfusion process can be monitored and fed back in real time.
