A method for treating congestive heart failure (CHF) has been developed that restores kidney renal functions by artificial vasodilation of at least one kidney. A vasodilator drug is locally delivered to the kidney via a kidney perfusion catheter. The drug can be mixed with the patient's blood, saline or other suitable solvent and the mixture directly applied to the kidney through the catheter. The restoration of kidney function assists the heart by removing excess fluid, urine and toxin from the patient, and by normalizing the patient's renin-angiotensin system and other neurohormonal substances. The method is applicable to treat chronic and acute CHF.

A bladder syringe for a fluid delivery system includes a cylindrical body, a cap-bladder assembly, a plunger element disposed in the cylindrical body, and a mounting assembly to secure the cap-bladder assembly to the cylindrical body. The cylindrical body has a distal end and a proximal end and defines a throughbore. The cap-bladder assembly is adapted for connection to the distal end of the cylindrical body, and includes a cap body and a bladder. The cap body defines an interior cavity and a distal discharge conduit and is adapted to engage the distal end of the cylindrical body. A disc-shaped bladder is disposed within the interior cavity and typically includes a central membrane portion. The plunger element is disposed in the throughbore of the cylindrical body and is vented to enable evacuation of the space between the plunger element and the cap-bladder assembly in the cylindrical body.

A survival suit including two bladders filled with air exhaled from the user to provide warmth and floatation. The first bladder is located against the user's back that covers the entire dorsal region. Located behind the first bladder is a second bladder that acts as an insulation layer when submerged under water. Both the first and second bladders are filled with fibrous filler material to provide insulation and allow exhaled air to flow freely therein. An air conduit extends from the user's mouth to the second inner bladder. Formed between the first and second bladders is an air passageway that delivers air from the second bladder into the first bladder. Air outlet ports located on the first bladder allows exhaled air to escape into the body cavity and that completely surround the user. The exhaled air in the body cavity eventually escapes through the face opening.

The invention discloses a preparation method of an anti-phlegm embolus tracheal catheter loaded with a hydrogel coating. The hydrogel coating is adopted to solve the problem that the tracheal catheter is easy to block. Due to the hydrophilic and water-locking characteristics of the hydrogel coating, phlegm can move downwards to the lung along the hydrogel coating of the tracheal catheter, and the situation that the catheter is blocked due to adhesion, aggregation and even dryness of the phlegm is avoided; and when the tracheal catheter is smooth, colonization of bacteria is reduced, so that formation of a biological membrane can be inhibited, and the probability of occurrence of ventilator-related pneumonia can be greatly reduced.

The invention relates to the technical field of medical products, and discloses an automatic 'urine three-cup test' specimen collection device. A distributing damper capable of deflecting towards two sides of a distributing cavity is arranged above a partition plate in the distributing cavity, two or more automatic closed catheters on the partition plate are arranged in the distributing cavity and penetrate the bottom of the distributing cavity, urine collecting tubes are connected to the lower ends of the automatic closed catheters and can be separated from the automatic closed catheters, and the automatic closed catheters are distributed on two sides of the distributing damper. Openings of the upper ends of the adjacent automatic closed catheters have a certain height difference, urine of a patient is automatically separated into different stages and collected by the aid of the height difference of the openings of the closed catheters and the distributing damper, and accuracy of 'urine three-cup test' results can be improved.

The invention provides a blood vessel thrombus extraction device which comprises a suction catheter for sucking a thrombus, a thrombus extractor for breaking the thrombus and a blocking structure for blocking the blood vessel in a region where the thrombus is located through self-expansion. When a thrombus extraction operation is carried out through the blood vessel thrombus extraction device provided by the invention, firstly, the blocking structure can stretch into the region where thrombus is located, then the blocking structure is expanded to block the blood vessel at the position where the thrombus is located so as to temporarily slow down or cut off flowing of blood at the position where the thrombus is located, and then the thrombus extraction operation can be carried out through the thrombus extraction device and the suction catheter. At the moment, the blood at the position where the thrombus is located flows slowly or stops flowing, and thus, when the suction catheter sucks the thrombus, the suction amount of the blood can be effectively reduced, and a patient is prevented from losing more blood.
