The present invention relates to medical equipment, namely, devices for obtaining cytological material.

It is now known device for obtaining cytological material, consisting of a protective drainage, a hollow plunger mounted on its end a hollow cylinder made of foam and held inside a flexible wire plunger provided at its end with a brush (patent RF № 2175853 C1, And 61 In 10/00, 20.11.2001,)

This device has substantially tenoch cavity of destruction and there is no chance of material with a large area of this cavity.

The technical result of the invention is to expand the functionality of the device: providing noninvasive screening of cytological material and contact with a larger area of the investigated area of the cavity.

The technical result is achieved in that the device is made to be routed through the drainage, with the working part is made in the form of baskets with elastic blades, covered with cloth, one end fixed on the radius to the protective casing and the other end of the wire pusher with the possibility of changing the shape of the basket by the unfolding of the blades to the outlet of the casing.

The working parts in the form of baskets with blades provides a greater area of contact with the test material, encourage adequate contact with the area of destruction. The execution of the elastic blades, covered with cloth, reduces the possibility of injury to the walls of the cavity.

Thus, the proposed device for obtaining cytological material extends the functionality provides greater contact area with the test material, encourage adequate contact with the area of destruction, reduces the possibility of injury to the wall of the bands is de.

In Fig. 2 presents a diagram of the device in working condition.

In Fig. 3 presents a diagram of the device at the time of extraction of the material from the cavity of destruction.

The device is a protective casing 1, which is installed inside a flexible wire pusher with 2 fixed on its end a basket with four flexible blades 3, covered with cloth, the other end of the blade 3 is attached radially to the protective casing 1 so that the exit can change its shape by extending blades.

The principle of operation. After pre-rehabilitation of saline solution through existing patient drainage 5, the proposed device in a protective casing 1 is supplied to the cavity of destruction 6. Using flexible wire pusher 2 translational motion vyvorachivaet of the protective casing basket with elastic blades 3, producing a touch fabrics.

An example of a specific application: the Patient S., 62 years of age, was treated in the Department of purulent surgery Bureau, Kursk with a diagnosis of Biliary infected Subtotal total pancreatic necrosis. Retroperitoneal septic cellulitis on the left.

The ultrasonographic examination revealed a cavity of destruction in the body and tail of pancreas W is Olney performed percutaneous drainage under ULTRASOUND control pancreatic abscesses in the area of the pancreas and left-sided retroperitoneal phlegmon. Evacuated a total of 180 ml of pus, sequestrum and hemorrhagic fluid. Put the drains with a diameter of 13 mm

The device is inserted through put drainage in pre-washed with saline cavity to contact with the wall. Flexible wire pusher of the protective casing divorciadas basket, producing a touch tissues, after which she was voracious back into the protective cover and the device is removed from drainage. Conducted microscopic examination of the material obtained. Conclusion: purulent inflammation, degenerative-inflammatory type.

After the procedure was conducted in a continuous flow and fractional cavity lavage. In dynamics was performed repeated cytological examination of tissues. Before discharge from the hospital were fistulography residual cavity.

The proposed device in the clinic for surgical diseases produced 11 cytological studies of patients with abscesses stuffing bags and retroperitoneal septic phlegmon with pancreatic necrosis. Complications from the use of this device is not marked.

Claims

The device obtained is different, however, the device is made for the liner through the drainage, with the working part is made in the form of baskets with elastic blades, covered with cloth, one end fixed on the radius to the protective casing and the other end of the wire pusher with the possibility of changing the shape of the basket by the unfolding of the blades to the outlet of the casing.

FIELD: medicine, clinical toxicology.

SUBSTANCE: at patient's hospitalization one should gather the data of clinical and laboratory values: on the type of chemical substance, patient's age, data of clinical survey and laboratory values: body temperature, the presence or absence of dysphonia, oliguria being below 30 ml/h, hemoglobinuria, erythrocytic hemolysis, exotoxic shock, glucose level in blood, fibrinogen and creatinine concentration in blood serum, general bilirubin, prothrombin index (PTI), Ph-plasma, the state of blood clotting system. The state of every sign should be evaluated in points to be then summed up and at exceeding the sum of points being above "+20" one should predict unfavorable result. At the sum of "-13" prediction should be stated upon as favorable and at "-13" up to "+20" - prediction is considered to be doubtful.

EFFECT: higher accuracy of prediction.

SUBSTANCE: method involves studying blood samples with venous blood mixed with vital stain like methylene blue. Degree of vital stain absorption by erythrocytes is determined by applying photocolorimetry. The value drop being more than 25%, extracorporal detoxication is to be predicted as ineffective.

EFFECT: simplified method.

SUBSTANCE: method involves evaluating prognostic signs and calculating their prognostic weight. Consciousness disorders and diagnosis set at prehospital stage are used as the prognostic signs. Calculations are carried out from formula: lethal outcome %= -15.99+19.1•C+14.7•DS-2.79•C•DS, where C is the ranged consciousness disorder degree, DS is the diagnosis set prehospital stage. The higher is the value, the higher is lethal outcome probability.

EFFECT: accelerated and simplified prognosis method.

SUBSTANCE: method involves evaluating proliferating processes by calculating index of positive cell nuclei (Ki-67). The Ki-67 value being from 6 to 16%, erosive ulcerating stomach lesions accompanied by stomach hemorrhage and hemorrhagic shock is to be predicted. The value being from 17 to 30%, erosive ulcerating stomach lesions without hemorrhage is to be predicted.

EFFECT: high accuracy of prognosis.

SUBSTANCE: the present innovation deals with differential diagnostics of prostatic cancer and other prostatic diseases at the stage of primary inspection. The method includes the detection of PCA and calculation of probability coefficient for prostatic cancer (PCC) by the following formula: where e - the foundation of natural logarithm (e=2.718…), PCA - the level of total blood PCA in ng/ml, V - patient's age in years. At PCC value being above 0.2 one should diagnose prostatic cancer and to establish final diagnosis one should perform polyfocal prostatic biopsy. The method enables to increase accuracy of diagnostics at decreased number of unjustified prostatic biopsies.

EFFECT: higher efficiency of diagnostics.

SUBSTANCE: method involves measuring radio signals and low frequency spectra of signals emitted by oral cavity organs and tissues in maxillofacial area. Decoding and comparison of the spectra to healthy organs and tissues spectra is carried out. Then, modulated information signals in infra-low frequency bandwidth corresponding to healthy organs and tissues signals are applied. Low frequency radio signals and spectra are measured. Treatment with modulated signals in infra-low frequency bandwidth is applied directly to organ or its location zone via skin.

EFFECT: enhanced effectiveness in diagnosing and treating oral cavity organs and tissues in maxillofacial area.
