Description

Urological dnagiostatic comilex, flowmeter (variaitis) in the mechanism

catheter traction

The invention relates to medical equipment, namely to devices for the diagnosis of urological diseases.

Known urological diagnostic complex "Relief - DIM, containing an information processing device connected to peripheral diagnostic and actuating devices, one of which is a flowmeter and catheter traction mechanism 1. The above-mentioned peripheral devices have design flaws that reduce the reliability, ergonomic characteristics and versatility of the complex generally. So, the gravity flowmeter, which is part of the complex, is not autonomous, so patients are forced to constantly visit a medical institution.

A self-contained flowmeter of the company DANTEC (Denmark) of a gravitational type is known, which contains a housing with a movable cover that is sanded on dynamometric sensors connected to an information processing device and a storage device located inside the housing, the latter being able to be connected to an external reading device and also includes a urine cone with with a jet cutter, a urine collection container installed on the lid and the power supply 2. The patient after a certain time interval, depending on the amount of memory apominayuschego device delivers flowmeter to the laboratory, where the reading of the information and its processing device in vneschnem. This is because the flowmeter cannot be operated as part of the urological diagnostic complex, which reduces its unversality. Before taking measurements, patients usually turn on the device by pressing the pedal, but many, especially older people, often forget to do this, and the results of measurements necessary for diagnosis are distorted. In addition, in order to install a container for collecting urine in the upper brush, a recess was made, where urine often falls.

The catheter traction mechanism, which is also part of the DANTEC diagnostic complex (Denmark), contains a screw-nut with a moving nut, and the nut is equipped with a device for securing the distal part of the catheter. The nut stroke length is limited by the device in the form of end sensors 3. Sensors often exit failure, which reduces the reliability of the mechanism.

The task, for the solution of which a useful model is proposed, is to increase the reliability of operation, ease of use and universality of urological diagnostic devices.

IPC A 61 5/20, M 25/00

The urological diagnostic complex includes an information processing device connected to peripheral diagnostic and actuating devices, one of which is a catheter traction mechanism and flowmeter, the latter containing a device that allows it to work offline.

The inventive flowmeter has a housing with a movable cover resting on a torque sensor connected to an information processing device and a storage device located inside the housing, the latter having the ability to connect to an external reading device (personal computer), and also includes a receiving cone with a jet cutter, a container for collection of urine mounted on the cover, power supply. The flowmeter further comprises a device for connecting the sensor to an external information processing device, for example, which is part of the complex. The flowmeter may have the ability to work in standby mode, since the current consumption required for the operation of the device is very small and therefore there is no need to regularly turn on the setra before use.

It is better when the device for connecting the sensor is installed higher than the lower cut, which helps to avoid splashing urine on it.

Also claimed is Flowil & gr, comprising a housing with a movable lid associated with a measuring sensor and having a platform for installing a urine collection container on top. The platform is convex in shape of a recess in the bottom of the urine container and can be round.

The inventive mechanism of traction of the catheter, ensuring its translational movement and return to its original position, contains a screw-nut transmission with a moving nut, and the nut is equipped with a device for securing the distal part of the catheter. The mechanism includes a device for limiting the stroke length of the nut, which contains at least one of the sides of movement power circuit element located at the end of the nut stroke. The screw-nut transmission is made with an intake cone with siphons for placing an element of a power circuit, which can be made in the form of a spring.

The inventive utility model is illustrated by graphic materials, where Fig. 1 shows a longitudinal section of a flowmeter, and in Fig. 2 shows a kinematic diagram of a catheter traction mechanism.

The utility model is illustrated by constructive methods of flowmeter and catheter, which are part of the urological diagnostic complex. Example 1. Flowmeter gravity type.

The flowmeter comprises a cup-shaped housing 1 with a movable lid 2, supported by a hinge 3 and a torque sensor 4, which is connected to the microprocessor 5 and memory 6, the latter being able to be connected to an external reading device via connector 7. Sensor 4 is also electrically connected to the terminals connector 7. The flowmeter includes a receiving cone 9 mounted on a rod 8 with a jet cutter 10, as well as a measuring cup 11 with divisions for collecting urine, installed on a convex platform 12 of the cover 2, made according to a recess 13 at the bottom of the cup 11, and a battery 14, the capacity of which should provide the required number of measurements. Microprocessor 5, device 6, and battery 14 are mounted on board 15.

 when used, it is constantly on and in constant standby mode. A stream of urine flows through the cone 9 without pressure along the walls of the cutter 10 into the circle 11. The dynamics of urination are detected by the sensor 4, the signal from which is processed by the microprocessor 5, and the received information is stored by the device 6. After the required number of measurements has been taken, the information from the memory device 6 is read through the connector 7 external reader (e.g. personal computer). In non-autonomous operation, for example, as part of a urological diagnostic complex, the signal from the sensor 4 is directly removed through connector 7 by an external reader included in the complex

Example 2. The mechanism of traction of the catheter,

The catheter traction mechanism includes a cylindrical housing 16, in which a microelectromotor 17 is mounted, the shaft of which is connected through the coupling 18 to the driving shaft screw 19, on which the nut 20 is located. sections of the shaft adjacent to the threaded part. The nut 20 is equipped with a slider 23, passing through the longitudinal groove 24 to 16, and a mechanical clamp 25 for securing the distal part of the catheter. In the places of the runoffs 21 and 22, coil springs 26 and 27 with free ends are mounted in the housing 16.

Before traction, the distal part of the catheter is fixed by a clamp 25, with the nut 20 being in the extreme right position. The rotation of the shaft of the microelectric motor 17 through the clutch 18 is transmitted to the running shaft 19, and the nut 20 begins to move, providing traction movement. Having reached the runaway 21, the nut 20 abuts against the spring 26, comes off the thread and stops. To ensure the return of the nut 20 to its original position, the shaft of the microelectric motor 17 begins to rotate in the opposite direction, while under the action of the spring 26, the nut 20 engages with the threads of the shaft 19 and begins to move in the opposite direction, where, having reached the run 22, it abuts the spring 27, gets off the thread and stops.
