Description

The device refers to a medical technique designed to perform surgical operations that require the patient's arm, leg and body to be fixed in a certain position for anesthesia and analgesia.

In particular, the role of locoregional anesthesia (LRA) has been increasing among anesthesia techniques in the last 20 years. Research has shown that this is particularly the case with the choice of anesthetic technique during traumatic and orthopedic surgery. [1] Among the directions in which the development of the LRA is particularly rapid is the development of devices to ensure a comfortable physiological position for the patient, as well as the convenience of doctors and medical staff. Prior to fixing the required positions, it is desirable to allow for a free range of physiological movements, particularly in the area of the shoulder and elbow, upper and lower arm, hip and thigh, knee and lower leg, and body.

Currently, LRA is performed in three major areas: upper and lower extremities and perimeter anesthesia in the spine (spinal and epidural). An urgent problem for physicians - anesthesiologists is the development of a universal removable device that allows for LRA in the upper and lower limbs and perimeter anesthesia in the spine. In addition, it is important to have a portable sonograph and Injectobloc neurostimulator in the physician's work area for a high-quality LRA. A portable sonograph is used for more accurate nerve localization with visual control. Injectobloc includes a neurostimulator, a perfuser for slow drug delivery and a pressure gauge for measuring injection pressure. Injectobloc also provides a function for recording and documenting manipulation - it records the electrical parameters used and the amount of anesthetic injected, which is important for keeping track records and anesthesia charts.

Various devices are known which partially solve the set goals. [3, 4, 5, 6, 7,8,9,10]

A device is known to achieve free range of motion in the shoulder and upper arm, elbow, and forearm with subsequent fixation in the required positions for LRA execution and to provide complete nerve blockage, free range of motion in the rubber joint and thigh, knee joint, and lower leg subsequent fixation to the required positions for LRA fulfillment and the provision of complete nerve blockage and fixation of the required body position (sitting) for perimeter anesthesia (spinal and epidural) in the spine. [11] A known device is a prototype.

When performing an LRA using a device - it is not possible to simultaneously secure the patient's arm, leg and body and the placement of a portable sonograph and Injectobloc neurostimulator in the doctor's work area for performing a high-quality LRA.

The object of the invention is:

1. To increase the quality of the LRA by expanding the functional properties of the device;

2. Provide 180 ° horizontal rotation of the console and additional 360 ° horizontal rectangular support for convenient positioning of the various support assemblies.

3. Ensure the stability of the device by attaching additional devices.

4. Increase the number of shelves for the convenience of doctors and medical staff.

The set objective is achieved by providing the device with an additional rectangular support in the form of a three-sided rectangle (12. 13, 14) with a 360 ° rotation in the horizontal plane, the lower horizontal rectangle (12) being fixed to the common support (5). at the console (7) level; in addition, the aspect ratio of the rectangular support (12, 13, 14) is 1: 1.2-1.3: 1.5-1.6, for example one is 23.6 cm. An additional shelf (16) is attached to the upper horizontal edge (14) of the rectangle, and the console (7) has a 180 ° rotation in the horizontal plane.

The device for locoregional anesthesia is pushed onto the patient's bed by means of a movable support frame (1) and the brake mechanisms (3, 3, 3, 3) of the wheels (2, 2, 2, 2) are locked by the doctor. When releasing the handle (6), mount the brackets (7) and the additional three rectangular brackets in the form of a rectangle (12, 13, 14) to the required height and secure with the handle (6). Apply a soft cloth to the body of the body in the form of a pad (37) and rest the front of the patient's chest against it. The patient's forearms are placed on additional supports (41, 41) while the patient's palms surround the handles (42, 42). The comfortable position of the body of the patient is obtained by adjusting the alignment of the support pad (37) in the vertical plane around the sham (38) and by the turns of the clamp (39) around the pivot axis (8) in the horizontal plane. Achieve a comfortable position with the handle (40). In addition to a comfortable support body body (37), the position is obtained by turning the console (7) around the common support (5) and securing it with the handle (11), as well as moving the movable support frame (I) if necessary. After fixing the body, the user places the rotating shelves (20, 21) in a comfortable position with the tooling, the cover (23) with the attached neurostimulator "Injectobloc" and the shelf (16) with the portable sonograph. The height of the shelves (20, 21) and the latch (23) is changed by moving the bar (19) in a vertical plane in the opening of the movable sham (17) and secured by the handle (18). In addition to the shelves (20, 21) there is a possibility of rotation around the bar (19) in the horizontal plane. This position is secured with the fixing screws (22, 22).

If no support kits (24, 25, 30, 30, 37) are used to fix the patient's arm, leg and body, the console (7) is not attached to the total support (5) and the device is used as a movable stand for the necessary tooling, neurostimulator Injectobloc and a portable sonograph. The positions of the shelves (16, 20, 21) and the shelf (23) are adjusted in the same way as using the support assemblies (24, 25, 30, 30, 37) - the user puts the rotating shelves (20, 21) ) with an attached "Injectobloc" neurostimulator and a shelf (16) with a portable sonograph. The height of the shelves (20, 21) and the latch (23) is changed by moving the bar (19) in a vertical plane in the opening of the movable sham (17) and secured by the handle (18). In addition to the shelves (20, 21) there is a possibility of rotation around the bar (19) in the horizontal plane. This position is secured with the fixing screws (22, 22).

The new device is versatile, portable and allows for LRA of the upper and lower limbs, as well as perimeter anesthesia in the spine, controlling the quality of anesthesia with the Injectobloc portable sonograph and neurostimulator. Additional rectangular support in the form of three sides of a rectangle (12, 13, 14) in proportions of 1: 1,2-1,3: 1,5-1,6, for example one of 23,6 cm and with the possibility of turning in the horizontal plane 360 ° extends the functionality of the device and ensures the stability of the device in the case of additional attached shelves and the devices on them - a working tool, a portable sonograph and an Injectobloc neurostimulator, which are needed for quality LRA. A variety of support kits are used to find a comfortable patient position - a support set in the form of a palette (24, 25), a support set for the lower leg in the form of a pallet (30, 30) and a support set for the body. Their use is facilitated by the fact that the console (7) has a 180 ° rotation in the horizontal plane.

The device is versatile, easy to move and fix, easy to disassemble and transport.
