The embodiment is shown in the drawings, which is a preferred embodiment of the present utility model. The utility model provides an auxiliary positioning device during scanning, mainly includes bottom plate 10, bottom plate 10 is installed perpendicularly in the both sides of length direction, baffle 1 is divided into anterior segment and back segment along length direction, two on the back segment of baffle 1 all offer the connecting hole, the axis of connecting hole is perpendicular to the face of baffle 1, sliding connection has connecting rod 9 on the connecting hole, splint 7 are installed to one end of connecting rod 9, two splint 7 support respectively on the both sides of patient's wrist, install first nut 8 and second nut 11 on the connecting rod 9, first nut 8 is located splint 7's medial surface, second nut 11 is located splint 7's lateral surface; a fixed belt 12 with adjustable length is arranged between the two clamping plates 7, and two ends of the fixed belt 12 are respectively connected to the inner side surface of one clamping plate 7; the fixing pillow 6 is detachably arranged on the bottom plate 10, the fixing pillow 6 is made of soft materials, the fixing pillow 6 is positioned on the bottom plate 10 at the front section of the baffle plate 1, a strip-shaped slide hole 2 is formed in the front section of the baffle plate 1, the length direction of the slide hole 2 is in the vertical direction, a pressing plate 5 is arranged between the two baffle plates 1, the pressing plate 5 is made of nonmetallic hard materials, the pressing plate 5 is pressed on the front palm of a patient, sliding rods 3 are arranged at two ends of the pressing plate 5, the sliding rods 3 slide in the slide holes 2, a third nut 4 is connected to each sliding rod 3 in a threaded manner, and the two third nuts 4 are positioned on the outer side surface of the baffle plate 1; the outer part of the fixed pillow 6 is sleeved with a pillowcase.

In the specific use process, the utility model has the advantages that the wrist and the fingers of a patient are required to be placed flatly and straightly when being scanned, and the fingers are opened and straightened, so that the examination result obtained by scanning is more accurate due to the placing posture. Therefore, the base plate 10 is firstly placed in the middle of the examination bed during scanning, so that the scanner is convenient to use for scanning. The patient places the wrist and palm on bottom plate 10, and the splint 7 through installing on baffle 1 centre gripping is in patient's wrist both sides for patient's wrist is difficult for crooked to both sides, because the thickness of the wrist of every patient is different, so the distance between two splint 7 that need is different. In this regard, the positions of the clamping plates 7 at the ends of the connecting rod 9 can be adjusted by sliding the connecting rod 9 through the connecting holes in the baffle plate 1, so that the distance between the two clamping plates 7 can be adjusted to be suitable for patients with wrists of different thicknesses. After the position of the clamping plate 7 is adjusted, the first nut 8 and the second nut 11 are in threaded connection on the connecting rod 9, so that the first nut 8 and the second nut 11 are respectively clamped on the inner side surface and the outer side surface of the baffle plate 1, and the connecting rod 9 slides in the connecting hole, so that the position of the clamping plate 7 is fixed. Further, in order to prevent the patient's wrist from being lifted during scanning, a fixing band 12 is installed between the two splints 7, and the length of the fixing band 12 can be adjusted, and the patient's wrist is fixed by the fixing band 12 so that the patient's wrist cannot be lifted. Further, the fixing strap 12 is installed on the inner side surfaces of the two clamping plates 7, so that the fixing strap 12 can be better contacted with the wrist, and the effect of fixing the wrist is improved. After the placement position of the wrist is adjusted, the placement position of the fingers of the patient needs to be adjusted, because the fingers of the human body can be involuntarily combined and bent under the natural state. Therefore, further, the fixed pillow 6 is arranged on the bottom plate 10, the fixed pillow 6 is made of soft materials, the fingers of the patient are pressed on the fixed pillow 6 after being opened, the fixed pillow 6 deforms under the action of force, the palm and the fingers of the patient are embedded in the fixed pillow 6, and the fixed pillow 6 is filled between the finger slits, so that the fingers of the patient are separated to be opened. In order to prevent the finger of the patient from being bent unconsciously, a pressing plate 5 is arranged between the two baffle plates 1, and the finger joints of the patient are straightened and are not easy to bend by pressing the pressing plate 5 on the front palm of the patient. Because the finger thickness varies from patient to patient, the height requirements for the platen 5 are also different. Therefore, further, the slide bars 3 are installed at the two ends of the pressing plate 5, the slide bars 3 slide up and down in the slide holes 2 on the baffle plate 1, after being adjusted to a proper position, the slide bars 3 are in threaded connection with the slide bars 3 through the third nuts 4, so that the two third nuts 4 are respectively abutted to the outer side face of the baffle plate 1, the clamping effect of the two third nuts 4 on the baffle plate 1 is achieved, the position of the pressing plate 5 is fixed, the pressing plate 5 is used for pressing the finger joints of a patient conveniently, the fingers of the patient are opened and straightened, and scanning is convenient. Because of the very large number of patients that need to be scanned every day, disinfection is required. However, the fixed pillow 6 is made of soft material, which is inconvenient to sterilize. Therefore, the pillow case is sleeved outside the fixed pillow 6, and the pillow case can be replaced to avoid cross infection among patients. Furthermore, the pillowcase can be a disposable pillowcase, and is similar to a disposable shoe cover, and the pillowcase can be directly discarded after use, so that the use is convenient, and the time for sterilizing the pillowcase is reduced.

Further, the inner filler of the fixing pillow 6 adopts latex particles, because the latex particles are separated from each other, after the patient presses the latex pillow with hands, the fingers and the palm are more easily embedded into the fixing pillow 6 with the latex particles, and the latex particles have elasticity, and when the latex particles are pressed with hands and the pressing plate 5 is pressed on the front palm, the latex particles are contacted with the hands of the patient, so that the comfort level can be improved. After the use is finished, the fixing pillow 6 is dithered, so that the latex particles in the pillow can be quickly restored to the original state.

Further, the upper end surface of the bottom plate 10 is provided with a plurality of buckling seats, the lower end surface of the pillow case of the fixed pillow 6 is provided with a plurality of snap fasteners, and the snap fasteners are detachably connected with the buckling seats, so that the position of the fixed pillow 6 is not easy to deviate.

Further, a plurality of fixing ropes are arranged on two sides of the pillowcase, a plurality of fixing holes are formed in each baffle plate 1, and the end parts of the plurality of fixing ropes penetrate out of the fixing holes and are fixed on the outer side of the baffle plate 1. The fixing ropes on the pillowcase are penetrated out of the baffle plate 1 from the inner side of the baffle plate 1 through the fixing holes, and the fixing ropes extending out of the baffle plate 1 are connected with each other, so that the pillowcase is fixed on the bottom plate 10.

Further, the inner side surface of the clamping plate 7 is provided with a soft cushion, so that comfort is improved.

Further, the fixing strap 12 adopts a flat broadband structure, so that comfort is improved, and the fixing strap is not easy to be injured by a user.

Further, the lower end surface of the bottom plate 10 is provided with a non-slip pad, so as to reduce the movement of the bottom plate 10.

Further, the pressing plate 5 is made of transparent material, so that the hand condition of the patient can be clearly seen.

The foregoing description is directed to the preferred embodiments of the present utility model, but the embodiments are not intended to limit the scope of the utility model, and all equivalent changes or modifications made under the technical spirit of the present utility model should be construed to fall within the scope of the present utility model.
