Description

Adjustable hand fixer for bone density determination

Technical Field

The utility model relates to a hand fixer, concretely relates to bone density survey is with adjustable hand fixer belongs to hand fixer technical field.

Background

The bone density measurement has high sensitivity and high diagnosis rate for osteoporosis caused by various reasons; the early diagnosis and the curative effect observation of the osteoporosis can be carried out; bone density measurement is also a conventional operation for obstetrical measurement of calcium loss of pregnant and lying-in women, and generally is used for measuring the density of radius bones; in the measuring process, the hand of a patient is easy to shake, and the bone density probe cannot accurately find the position of the radius, so that the detection speed and precision are influenced; to this end, the chinese patent application number; 201520200835.1, discloses an adjustable hand fixer for bone density determination, comprising a left fixing plate and a right fixing plate, wherein the bottom end of the left fixing plate is connected with a left adjusting toothed plate with teeth, the bottom end of the right fixing plate is connected with a right adjusting toothed plate with teeth, the left adjusting toothed plate and the right adjusting toothed plate are positioned between the left fixing plate and the right fixing plate, the left adjusting toothed plate and the right adjusting toothed plate are connected through a gear, the left fixing plate and the right fixing plate are inverted-shaped plates, and the left fixing plate and the right fixing plate are symmetrically installed with openings; in the operation process, the hand is difficult for rocking, and the radius is detected more easily to the bone density probe, and during the measurement, the radius scanning process is as follows: after scanning starts, the probe falls down perpendicular to the arm position; firstly, rotating the probe outwards to scan about 70 degrees; continuing to scan, and returning the probe to the initial position; then, scanning in the opposite direction, wherein the angle is about 70 degrees, and finally, returning to the starting point; the above-mentioned process is repeated until the measuring cycle is accomplished, and above-mentioned technical scheme timing is pressed from both sides tightly the back, still can outwards expand to lead to fixed failure, in addition, during its survey, both unable auxiliary probe location had, when the probe swing, caused the probe upset easily to block simultaneously.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a bone density survey is with adjustable hand fixer can realize that the hand flexible clamp is tight, can assist probe location and scanning simultaneously.

The utility model discloses an adjustable hand fixer for bone mineral density survey adopts a base that can hold the slip table, the slip table is double-slider structure, the hand wheel rotates and can drive the lead screw to rotate, two sliders on the lead screw convert circular motion into linear motion, thereby make two sliders approach each other and keep away from each other, thereby can drive the adjusting seat on the slider to carry out clamping and releasing to the hand, set up a hand supporting platform between two adjusting seats, can fix a position the bottom surface of the hand, after accomplishing the location, carry out the lateral part through adjusting the seat and press from both sides tightly, when the hand is placed on the hand supporting platform, must make the radius line position of marking on the hand align with side groove height line, after the scanning begins, the probe falls off perpendicular to the arm position; one side of the probe is close to the height line of the side groove; because the side groove has a high position and a low position, the back side (radius) of the arm is exposed, and at the moment, the probe is firstly rotated outwards to scan an angle of about 70 degrees; continuing to scan, and returning the probe to the initial position; then, scanning in the opposite direction at an angle of about 70 degrees, finally returning to the starting point, and guiding the probe by the high and low positions of the side close to the side groove of the probe in the whole scanning process, wherein the probe cannot be blocked by the fixer in the rotating process; the manual screw rod sliding table is fixed on the inner side of the square groove base; the manual screw rod sliding table is a double-slider sliding table; each sliding block of the manual screw rod sliding table is fixedly provided with an adjusting seat; a hand supporting platform is radially fixed in the middle of the square groove base; the two adjusting seats comprise square seat bodies, and one surfaces, close to each other, of the two square seat bodies are provided with cushion grooves; a rubber pad is fixed on the pad groove; one side of the top surfaces of the two square seat bodies is provided with a side groove; the supporting platform top surface is fixed with an at least cushion, and the cushion number of piles can be confirmed according to the person's of awaiting measuring forearm width, and it is spacing to adopt the flexonics through the cushion, can enough press from both sides tight hand, avoids hand and fixer hard contact simultaneously.

As a preferred embodiment, the threads of the two sliding blocks are opposite, the lead screw is driven to rotate through the hand wheel, and the two sliding blocks can approach to or separate from each other.

As a preferred embodiment, the bottoms of the two square groove bases are provided with silica gel base plates.

Compared with the prior art, the utility model discloses an adjustable hand fixer is used in bone density survey can realize that the hand flexible clamp is tight, and the hand clamp force is stable, and the probe upset can lead to, auxiliary probe location and scanning.

Detailed Description

Example 1:

as shown in fig. 1, the utility model discloses an adjustable hand fixer for bone mineral density determination, adopt a base that can hold the slip table, the slip table is two slider structures, the hand wheel rotates and can drive the lead screw and rotate, two sliders on the lead screw convert circular motion into linear motion, thereby make two sliders be close to each other and keep away from each other, thereby can drive the regulation seat on the slider and carry out the centre gripping and release to the hand, set up a hand supporting platform between two regulation seats, can fix a position the bottom surface of the hand, after accomplishing the location, carry out the lateral part through adjusting the seat and press from both sides tightly, when the hand is placed on the hand supporting platform, must make the mark out radius line position on the hand align with side groove height line A, after the scanning begins, the probe falls perpendicularly to the arm position; one side of the probe is close to the height line A of the side groove; because the side groove has a high position and a low position, the back side (radius) of the arm is exposed, and at the moment, the probe is firstly rotated outwards to scan an angle of about 70 degrees; continuing to scan, and returning the probe to the initial position; then, scanning in the opposite direction at an angle of about 70 degrees, finally returning to the starting point, and guiding the probe by the high and low positions of the side close to the side groove of the probe in the whole scanning process, wherein the probe cannot be blocked by the fixer in the rotating process; comprises a square groove base 1 and a manual screw rod sliding table 2 fixed on the inner side of the square groove base; the manual screw rod sliding table 2 is a double-slider sliding table; each slide block of the manual screw rod sliding table 2 is fixedly provided with an adjusting seat 3; a hand supporting platform 4 is radially fixed in the middle of the square groove base 1; the two adjusting 3 seats comprise square seat bodies 31, and one surfaces, close to each other, of the two square seat bodies 31 are provided with cushion grooves; a rubber pad 32 is fixed on the pad groove; one side of the top surfaces of the two square seat bodies 31 is provided with a side groove 33; the top surface of the supporting platform 4 is fixed with at least one rubber mat 32, and the rubber mat is in flexible contact limiting, so that the hand can be clamped, and meanwhile, the hand is prevented from being in hard contact with the fixer.
