Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a hand fixation device. Background Technology
[0002] During certain medical procedures or examinations, it is often necessary to immobilize the patient's hands to ensure the smooth progress of the procedure. For example, during painless endoscopy, patients typically lie on their left side. During intravenous general anesthesia, the required drug dosage varies from patient to patient, making it difficult for anesthesiologists to accurately calculate the amount needed for each patient. Furthermore, to ensure safety, anesthesiologists often use less medication than actually required. The time required for each endoscopy is also variable. When biopsies are needed for lesions or endoscopic surgery, the examination time is often longer. Many patients regain consciousness before the examination is completed, but in the initial stage of consciousness recovery, they are not fully awake, and their limbs are uncontrollable, making hand movement very likely. For example, in the left lateral decubitus position, the right hand is usually placed on the lateral side of the right lower limb. Right hand movement not only interferes with the normal progress of the endoscopy and increases the "unnecessary workload" for medical staff, but excessive movement can also cause the indwelling needle fixed to the back of the right hand to slip out and cause bleeding at the needle insertion site, leading to dissatisfaction from patients and their families. Therefore, it is necessary to effectively immobilize the patient's hands before the examination begins to minimize the occurrence of the aforementioned adverse events.
[0003] Existing hand immobilization devices mostly rely on independent height and angle adjustment mechanisms to adjust the height of the hand immobilization platform and its rotation angle around the vertical axis, resulting in a relatively complex structure. Furthermore, existing hand immobilization devices lack a fixed structure for integration with the hospital bed, making them inconvenient to use. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The purpose of this utility model is to provide a hand fixing device to solve the problems existing in the prior art. It simplifies the structure, occupies less space, saves space, and is easy to use.
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] like Figures 1-3As shown, this embodiment provides a hand fixation device 100, including a fixation platform 1, a fixation body 2, a first support rod 3, a second support rod 4, a first locking component 5, and a clamping device 6. The fixation body 2 is disposed on the fixation platform 1 and is used to fix the patient's hand. The fixation platform 1 is fixedly connected to one end of the first support rod 3. The other end of the first support rod 3 is movably connected to one end of the second support rod 4. The first support rod 3 can move relative to the second support rod 4 along the center line of the second support rod 4 and can rotate relative to the second support rod 4 around the center line of the second support rod 4. The first locking component 5 can be connected to the second support rod 4 and can lock the first support rod 3 onto the second support rod 4. The clamping device 6 is disposed at the end of the second support rod 4 away from the first support rod 3 and can clamp onto the hospital bed. By rotating the first support rod 3 along the second support rod 4, the angle of the fixed platform 1 around the vertical axis can be adjusted. By moving the first support rod 3 along the centerline of the second support rod 4, the height of the fixed platform 1 can be adjusted. After the angle and / or height of the fixed platform 1 are adjusted, the first locking component 5 can lock the first support rod 3 and the second support rod 4, fixing them relative to each other. At this time, the position of the fixed platform 1 is fixed, and the hand can be secured. Since the first support rod 3, the second support rod 4, and the first locking component 5 can simultaneously adjust the angle and height of the fixed platform 1, the structure is simplified, the space occupied is small, and space is saved. At the same time, the clamping device 6 can clamp onto the hospital bed to realize the application of the fixed platform 1, which facilitates the fixation of the patient's hand on the hospital bed and is easy to use.
[0027] In this embodiment, the first support rod 3 is sleeved inside the second support rod 4. The second support rod 4 has a first locking section 401 at one end near the first support rod 3. At least one notch is provided on the end face of the first locking section 401 near the first support rod 3, and each notch extends towards the clamping device 6. A first locking member 5 is sleeved outside the first locking section 401 and is threadedly connected to it. When tightened onto the first locking section 401, the first locking member 5 can press against the notched portion of the first locking section 401, thereby clamping the notched portion of the first locking section 401 onto the first support rod 3. Specifically, the first locking member 5 has a first internal thread, and the first locking section 401 has a first external thread. Due to the notch, when the notched portion of the first locking section 401 contacts and is pressed against the inner wall of the first locking member 5, the notched portion clamps the first support rod 3, thus fixing the first support rod 3 to the second support rod 4.
[0028] In a preferred embodiment, the inner wall of the first locking component 5 near the end of the first support rod 3 is tapered. During the tightening process of the first locking component 5 along the first external thread, the tapered inner wall can squeeze the notch portion, thereby reducing the inner diameter of the notch portion. The inner sidewall of the notch portion is in close contact with the outer sidewall of the first support rod 3 and clamps the first support rod 3, thus fixing the first support rod 3 and the second support rod 4.
[0029] It should be noted that the first locking component 5 is not limited to fixing the first support rod 3 and the second support rod 4 by squeezing the notch. The first locking component 5 can also be a bolt and a nut. The first support rod 3 is provided with a first through hole array, which includes multiple through holes arranged sequentially along the length and height directions of the first support rod 3. The second support rod 4 is provided with a second through hole array, which includes multiple through holes arranged sequentially along the length and height directions of the second support rod 4. The bolt can pass through one hole in the first through hole array and one hole in the second through hole array and then connect with the nut, thereby fixing the first support rod 3 and the second support rod 4.
[0030] In this embodiment, the clamping device 6 includes a fixed base 601, a movable base 602, and a locking knob 603. A second locking section 402 is provided at the end of the second support rod 4 away from the first support rod 3. The fixed base 601 is fixedly connected to the end of the second locking section 402 away from the first support rod 3. The movable base 602 is sleeved on the end of the second locking section 402 near the first support rod 3, and the movable base 602 can move relative to the second locking section 402 along the centerline direction of the second locking section 402. The locking knob 603 is located on the side of the movable base 602 away from the fixed base 601, and the locking knob 603 is threadedly connected to the second locking section 402. Specifically, the second locking section 402 is provided with a second external thread 10, and the locking knob 603 is provided with a second internal thread 11. When connecting to the hospital bed, first move the locking knob 603 away from the fixed base 601 according to the thickness of the bed board, so that the movable base 602 can move upward, making the distance between the movable base 602 and the fixed base 601 greater than the thickness of the bed. Then, place the movable base 602 and the fixed base 601 on the upper and lower sides of the bed respectively, and turn the locking knob 603 in the opposite direction until it can no longer be turned. The movable base 602 and the fixed base 601 are used to clamp and fix the hospital bed.
[0031] In this embodiment, the fixed body 2 is movably connected to the fixed platform 1, and the fixed body 2 can move relative to the fixed platform 1 in a direction perpendicular to the axis of the second support rod 4 and maintain its position.
[0032] In this embodiment, at least one guide bar 7 is fixedly connected to the outer surface of the fixed platform 1 away from the clamping device 6. The guide bar 7 extends from the end of the fixed platform 1 near the first support rod 3 to the end of the fixed platform 1 away from the first support rod 3. The fixed body 2 includes a strap assembly 201, a base 202, at least one slide rail 203 and at least one second locking component 204. The strap assembly 201 is fixedly connected to one side of the base 202. Each slide rail 203 is fixedly connected to the other side of the base 202. Each slide rail 203 corresponds to one guide bar 7, and each slide rail 203 can slide along the corresponding guide bar 7. The second locking component 204 can lock the slide rail 203 onto the guide bar 7.
[0033] In this embodiment, the strap assembly 201 includes a soft strap 205, a soft semi-ring 206, an adhesive strip 207, and a fixing ring 208. The soft semi-ring 206 is fixedly connected to the side of the base 202 away from the fixing platform 1. One end of the soft strap 205 is fixedly connected to one free end of the soft semi-ring 206, and the other end of the soft strap 205 is provided with the adhesive strip 207. The fixing ring 208 is fixedly connected to the other free end of the soft semi-ring 206. The end of the soft strap 205 with the adhesive strip 207 can pass through the fixing ring 208, and the adhesive strip 207 can be bonded to the soft strap 205. In this embodiment, the soft strap 205 only needs to be wrapped around the outside of the wrist, then inserted into and wrapped around the fixing ring 208, and then the free end of the soft strap 205 is pulled in the opposite direction to attach the adhesive strip 207 to the soft strap 205. This achieves hand fixation, which is convenient to operate. When the wrist is fixed too tightly, it can be loosened appropriately by using the adhesive strip 207, which can fully ensure blood circulation in the patient's right hand. The soft semi-ring 206 and soft band 205 are less likely to cause marks on the patient's wrist, while ensuring effective blood circulation in the patient's upper limb and improving comfort. The adhesive 207 is preferably Velcro.
[0034] In this embodiment, a soft pad 8 is fixedly connected to the side of the fixed base 601 near the movable base 602 and / or the side of the movable base 602 near the fixed base 601. In a preferred embodiment, both the movable base 602 and the fixed base 601 are provided with soft pads 8, and the soft pads 8 on the movable base 602 and the fixed base 601 are arranged opposite to each other.
[0035] In this embodiment, a diagonal brace 9 is also included. The two ends of the diagonal brace 9 are fixedly connected to the fixed platform 1 and the first support rod 3, respectively, which increases the stability of the support platform.
[0036] In this embodiment, each second locking component 204 is a screw, and at least one threaded hole is provided on at least one side wall of the slide rail 203. Each screw can be threadedly connected to a threaded hole, and the top of each screw can lock the slide rail 203 onto the guide rail 7 by contacting the side wall of the guide rail 7.
[0037] In this embodiment, a mounting groove 101 is provided on the side of the base 202 away from the fixed platform 1. The middle section of the soft semi-ring 206 is located in the mounting groove 101. Soft rubber is filled between the inner wall of the mounting groove 101 and the middle section to ensure the connection strength of the soft semi-ring 206. If the soft semi-ring 206 is completely above the fixed platform 1, the patient's hand will be directly pressed on the soft semi-ring 206, resulting in an indentation. However, in this embodiment, the middle section of the soft semi-ring 206 is recessed into the fixed platform 1, allowing the patient's hand to be placed on the fixed platform 1 and the soft rubber, which can protect the patient's wrist.
[0038] In a preferred embodiment, the guide bar 7 is a horizontal rail, and there are two guide bars 7. There are two second locking components 204. The soft semi-ring 206 is a rubber semi-ring, the soft pad 8 is a sponge pad, and the fixing ring 208 is a metal ring. More preferably, while ensuring strength, the width of the soft band 205 should not be too large to reduce the contact area with the hand, and to effectively dissipate heat when the endoscopic surgery operation time is long.
[0039] This embodiment can be used to fix the patient's hand during endoscopic examination. Taking the patient in the left lateral decubitus position as an example, the patient's right hand is above the patient's hip joint. The clamping device 6 is clamped to the bed according to the principle of proximity. The height of the first support rod 3 is adjusted according to the height of the patient's right hand. The angle of the first support rod 3 is adjusted according to the relative position of the patient's right hand and the fixation body 2. The position of the fixation body 2 on the guide strip 7 is further adjusted so that the fixation body 2 is between the right hand and the hip joint, or so that the fixation body 2 is close to the right hand. The right hand is placed in the soft semi-ring 206. The soft strap 205 is wrapped around the patient's wrist or hand and then passed through the fixation ring 208. The soft strap 205 is then tightened, and the adhesive 207 is attached to the soft strap 205 in the opposite direction to fix the hand, so that the patient's right hand and wrist cannot move easily. Meanwhile, the hand fixation device 100, with its height adjustment, angle adjustment, and position adjustment along the guide strip 7, can adapt to different patients. It facilitates adjustments during examinations, such as when a patient changes from a left lateral decubitus position to a right lateral decubitus or horizontal decubitus position, allowing for corresponding adjustments based on the patient's postural changes. Anesthesiologists can also adjust the height and / or angle of the hand support as needed to administer additional anesthetic drugs, facilitating timely supplementation. It should be noted that in actual use, the order of height adjustment, angle adjustment, and position adjustment along the guide strip 7 can be determined as needed. During surgery or examinations, there is no need for medical staff to manually fix the patient's hand, effectively reducing their workload and appropriately improving their work efficiency.
[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
