Description

Technical Field

[0001] The utility model belongs to the technical field of ophthalmology, and in particular relates to a clinical fixation device for children. Background Art

[0002] Ophthalmological patients under the age of 4 often undergo ophthalmic specialist examinations or treatments (such as eye examinations, tear duct probing, tear duct irrigation, etc.) as needed. However, due to the fear, unfamiliarity, and poor cooperation of the children, their heads and bodies shake violently, which often puts great psychological pressure on the operators and creates certain risks to safe diagnosis and treatment. The families of the children are also dissatisfied or even refuse to be examined due to fear and distress, which further delays or misdiagnosis in diagnosis and treatment.

[0003] The existing fixation method used in ophthalmology is to wrap the child's body with a sheet, one medical staff member fixes the child's head with both hands and presses the child's upper body with both elbows, another medical staff member fixes the child's knees, and the third medical staff member is the operator. It requires three people to work together to complete the task. In this way, only a simple fixation of the head and body can be performed, and the fixation effect is greatly related to the child's strength to break free and the strength of the medical staff. In addition, the operation lacks humanization and is prone to cause diagnosis and treatment risks.

[0004] The invention patent with publication number CN116492077A discloses a head and body fixer for children with poor cooperation in ophthalmology, including a head fixer, a shoulder-chest restraint belt and a knee restraint belt for use together. The head fixer is fixed to the head of the bed or pillow through the head strap, and the front side of the head fixer is hinged with a forehead support for fixing the forehead. The head fixer is U-shaped as a whole, which can fix the head and ears; the shoulder-chest restraint belt includes a shoulder-chest fixing belt and a shoulder-chest strap, the shoulder-chest fixing belt is worn on the shoulders, the lower end of the shoulder-chest fixing belt is connected to the middle of the shoulder-chest strap, and the two ends of the shoulder-chest strap are fixed to the two sides of the treatment bed, and the knee strap is fixed to the two sides of the treatment bed. The restraint belt includes a knee strap and a perforation. Two perforations are arranged in the middle of the knee strap. The knee strap wraps around the knee and passes through the perforations to be fixed on both sides of the treatment bed. Although the above technical solution can fix the head, shoulders and knees of the child, the above technical solution adopts a U-shaped head fixator, so when fixing the head and ears of the child, it will compress the ears of the child, making the child feel uncomfortable. At the same time, improper force will also affect the hearing of the child. Moreover, since the head fixator is an integrated structure, it is impossible to adjust the head fixation distance according to the size of the child's head, so the fixation effect is not very good.

[0026] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. Example 1

[0027] like Figures 1 to 5 As shown, the embodiment of the utility model provides a clinical fixation device for children, including a head fixation unit 1, a shoulder fixation unit 2, a leg fixation unit 3 and a bottom plate 4, wherein the head fixation unit 1, the shoulder fixation unit 2 and the leg fixation unit 3 are sequentially arranged on the top of the bottom plate 4 along the length direction of the bottom plate 4, and the head fixation unit 1 and the shoulder fixation unit 2 are respectively slidably connected to the bottom plate 4. The bottom plate 4 in this embodiment can be placed on an examination bed or other places for use, and the bottom plate 4 is made of a heavy material to prevent the bottom plate 4 from being moved randomly under force during the fixation of the child.

[0028] The head fixing unit 1 in the embodiment of the utility model comprises a first adjusting mechanism, a headrest 101, two head fixing plates 102, two ear protection members 103 and two accommodating holes 104, wherein the first adjusting mechanism is slidably arranged on the front side of the top of the base plate 4, and the headrest 101 is arranged on the top of the base plate 4. In the specific design, the headrest 101 can be placed on the top of the base plate 4, so that the position of the headrest 101 can be moved slightly according to the position of the head of the child lying down; the two head fixing plates 102 are respectively connected to the first adjusting mechanism, and the two head fixing plates 102 are located on both sides of the headrest 101, and the two ear protection members 103 are symmetrically arranged on the sides of the two head fixing plates 102 close to the headrest 101, and the two ear protection members 103 are respectively provided with ear holes 105 for placing ears, and through the design of the ear holes 105, the two head fixing plates 102 can be moved inward. When the two sides of the head are moved relative to each other to fix, the two ears of the child can enter the ear holes 105 respectively, so as to avoid the head fixing plate 102 pressing the two ears of the child and causing discomfort; the ear protection piece 103 in this embodiment is made of elastic materials such as silicone or rubber, and the ear protection piece 103 is an inverted frustum-shaped structure, so that when the head fixing plate 102 fixes the head, the ear protection piece 103 can make contact with the side of the head over a large area, thereby avoiding the head fixing plate 102 from causing damage to the surface of the child's head; two accommodating holes 104 are respectively provided on the two head fixing plates 102, and each accommodating hole 104 is connected to the ear hole 105 on the same side. Through the connection design between the accommodating hole 104 and the ear hole 105, the ear can be connected to the outside world, so as to avoid the head fixing plate 102 blocking the ear and affecting the hearing of the child when fixing the head.

[0029] The first adjustment mechanism in the embodiment of the utility model includes a sliding groove 106, a bidirectional screw 107, two threaded blocks 108 and two support plates 109, wherein the sliding groove 106 is opened at the top of the base plate 4, and the two support plates 109 are vertically arranged on the top of the base plate 4. In the specific design, the bottom of the support plate 109 can be welded to the base plate 4 to achieve the fixation of the two; the bidirectional screw 107 is rotatably connected to the two support plates 109 respectively through bearings, specifically, the bidirectional screw 107 passes through the two support plates 109, and the bidirectional screw 107 is rotatably connected to the two support plates 109 through bearings; one end of the bidirectional screw 107 is provided with a handle 5 for facilitating the pushing of the bidirectional screw 107 for rotation.

[0030] The two thread blocks 108 are respectively arranged on the two thread segments of the bidirectional lead screw 107, and the bottoms of the two thread blocks 108 are slidably connected with the sliding groove 106, and the two thread blocks 108 are respectively connected with the corresponding head fixing plate 102. In the embodiment of the utility model, the two thread blocks 108 are directional structure thread blocks, and since the bottoms of the two thread blocks 108 are respectively slidably connected with the sliding groove 106, the side walls of the sliding groove 106 have a limiting effect on the two thread blocks 108, and the limiting effect makes it impossible for the two thread blocks 108 to rotate with the bidirectional lead screw 107 when the bidirectional lead screw 107 rotates, and can only move closer to or away from each other along the bidirectional lead screw 107.

[0031] When the child's head needs to be fixed, the child lies flat on the base plate 4 and rests the back of the head on the headrest 101. Then the two-way screw 107 is rotated by the handle 5 to drive the two threaded blocks 108 to move closer along the two-way screw 107. When the two head fixing plates 102 and the ear protection pieces 103 move until the two ears enter the corresponding ear protection pieces 103 respectively, and the end faces of the ear protection pieces 103 are in contact with the sides of the child's head, and the head fixing plates 102 can no longer move, the rotation of the two-way screw 107 is stopped to complete the fixation of the child's head.

[0032] In the embodiment of the utility model, the shoulder fixing unit 2 includes a second adjustment mechanism, a restraint belt 201, multiple groups of hooks 202 and multiple hanging rings 203. The second adjustment mechanism is slidably arranged in the middle of the top of the base plate 4. One end of the restraint belt 201 is connected to the second adjustment mechanism, and multiple hanging rings 203 are connected to the second adjustment mechanism. Multiple groups of hooks 202 are arranged on the outer side of the restraint belt 201 away from the connecting end of the restraint belt 201. In the specific design, multiple groups of hooks 202 are respectively arranged along the length direction of the restraint belt 201, and multiple groups of hooks 202 are arranged parallel to each other. Each group of hooks 202 is arranged at intervals along the width direction of the restraint belt 201. Each group of hooks 202 is respectively hooked with corresponding hanging rings 203. The number of each group of hooks 202 is the same as the number of multiple hanging rings 203. In this embodiment, the number of each group of hooks 202 and the number of multiple hanging rings 203 are preferably 3, and the number of groups of hooks 202 is preferably 3.

[0033] In the embodiment of the utility model, the second adjustment mechanism includes two through grooves 204, two sliding rods 205, two sliders 206 and two connecting strips 207. The two through grooves 204 are symmetrically opened on two opposite side surfaces of the bottom plate 4, and the two sliding rods 205 are respectively arranged inside the through grooves 204, and the two ends of the two sliding rods 202 are respectively welded to the front side wall and the rear side wall of the through grooves 204, the two sliders 206 are respectively slidably connected to the sliding rods 205, the two connecting strips 207 are respectively welded to the corresponding sliders 206, and the restraint belt 201 and multiple hanging rings 203 are respectively bonded to the corresponding connecting strips 207.

[0034] When the upper body of the child needs to be fixed, the child lies flat on the top of the base plate 4, with the back of the head resting on the headrest 101, and the two arms of the child are placed flat on both sides of the body. Then, according to the height of the child, the two sliders 206 are moved to drive the restraint belt 201 and the hanging ring 203 to move forward and backward. When the restraint belt 201 and the hanging ring 203 are moved to the appropriate position, the restraint belt 201 is then pulled from one side of the body to pull the restraint belt 201 over the upper body of the child, and a group of hooks 202 at the appropriate position are hooked with multiple hanging rings 203 on the side. Since the upper body and two arms of the child are under the restraint belt, the upper body of the child is fixed.

[0035] The leg fixing unit 3 comprises a leg fixing belt 301, a first Velcro 302 and a second Velcro 303. The middle part of the bottom of the leg fixing belt 301 is connected to the top of the bottom plate 4. Specifically, any connection method of bonding or binding can be adopted, as long as the two can be fixedly connected. The first Velcro 302 is sewn on the inner side of one end of the leg fixing belt 301, and the second Velcro 303 is sewn on the outer side of the other end of the leg fixing belt 301. The two ends of the leg fixing belt 301 are bonded by the first Velcro 302 and the second Velcro 303. When it is necessary to fix the legs of the child, the legs are placed on the leg fixing belt 301, and the two ends of the leg fixing belt 301 are pulled from both sides toward the legs, so that the leg fixing belt 301 constrains the legs, and the legs are fixed by bonding the first Velcro 302 and the second Velcro 303. Example 2

[0036] like Figure 6 and Figure 7As shown, after the shoulder fixing unit 2 in the clinical fixing device for children of Example 1 adjusts the position of the restraint belt 201 according to the height of the child, if the child exerts force, it is possible to drive the restraint belt 201 to move forward and backward, thereby affecting the fixing effect. In order to solve the above problem, the embodiment of the utility model is further improved on the basis of Example 1, so that the slider 206 can be fixed after moving to a suitable position. Specifically, the tops of the two sliders 206 are respectively provided with threaded through holes 208, and the tops of the sliders 206 are provided with fixing bolts 209, which are inserted into the inside of the threaded through holes 208, and the bottom ends of the fixing bolts 209 are in contact with the top of the sliding rod 205. When the two sliders 206 are moved according to the height of the child, the restraint belt 201 and the hanging ring 203 are driven to move forward and backward. When the restraint belt 201 and the hanging ring 203 are moved to the appropriate position, the fixing bolt 209 is screwed downward to make it move downward along the threaded through hole 208 until the bottom end of the fixing bolt 209 abuts against the top of the sliding rod 205, so that the slider 206 cannot move along the sliding rod 205. Then, the fixing bolt 209 is stopped to fix the slider 206 to prevent the restraint belt 201 and the hanging ring 203 from moving freely with the slider 206 after the position of the restraint belt 201 and the hanging ring 203 is adjusted.

[0037] When the medical staff performs ophthalmic examination and treatment on the child and needs to fix the child's body, the child lies flat on the base plate 4 and rests the back of the head on the headrest 101. Then, the two-way screw 107 is rotated by the handle 5 to drive the two threaded blocks 108 to move closer along the two-way screw 107. When the two head fixing plates 102 and the ear protection pieces 103 move until the two ears enter the corresponding ear protection pieces 103 respectively, and the end faces of the ear protection pieces 103 contact the sides of the child's head, and the head fixing plates 102 can no longer move, the rotation of the two-way screw 107 is stopped to complete the fixation of the child's head. Then, the two arms of the child are placed flat on both sides of the body, and then, according to the height of the child, the two screws 107 are moved. The two sliders 206 drive the restraint belt 201 and the hanging ring 203 to move forward and backward. When the restraint belt 201 and the hanging ring 203 move to the appropriate position, the restraint belt 201 is then pulled from one side of the body to make the restraint belt 201 pass over the upper body of the child, and a group of hooks 202 at appropriate positions are hooked with multiple hanging rings 203 on the side. Since the upper body and both arms of the child are under the restraint belt, the upper body of the child is fixed; finally, the legs are placed on the leg fixing belt 301, and the two ends of the leg fixing belt 301 are pulled from both sides toward the legs, so that the leg fixing belt 301 restrains the legs, and the legs are fixed by bonding the first Velcro 302 and the second Velcro 303.

[0038] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
