Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary device technology, and in particular to a special pillow for patients with cranial traction. Background Technology

[0002] Cranial traction is a commonly used treatment method in spinal surgery. It can effectively restore the physiological curvature of the cervical spine, maintain cervical spine stability, and prevent further damage. It can be used as an important non-surgical treatment for cervical spine injuries and is also an important means of perioperative traction reduction in cervical spine surgery.

[0003] The standard position for cranial traction is supine. Generally, cranial traction is required for at least two weeks and must be maintained 24 hours a day. When the patient needs to turn over, the long screws on both sides of the cranial traction bow can affect the angle of repositioning, preventing effective turning and easily causing pressure injuries to the skin in vulnerable areas such as the back of the head, sacrum, coccyx, and scapulae, making skin care difficult. Furthermore, turning over can easily cause displacement of the patient's head, neck, and shoulders, affecting the traction effect and, in severe cases, causing secondary injury to the cervical spine. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a special pillow for patients undergoing cranial traction, which facilitates turning over and ensures that the patient's head, neck, and shoulders rotate as a whole during turning over.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A special pillow for patients with cranial traction includes a headrest, a traction mechanism, and a fixation mechanism;

[0007] The traction mechanism includes a traction bow, screws, and a traction assembly. The screws are used to fix the traction bow to the patient's head, and the traction assembly is used to pull the traction bow.

[0008] The fixation mechanism includes two fixation plates and a clamping assembly. The two fixation plates are used to fix the patient's two shoulders respectively. The clamping assembly is set on the two fixation plates and includes two clamping plates and a driving component. The driving component is used to drive the two clamping plates to move closer together to clamp and fix the patient's head on both sides.

[0009] The headrest is equipped with a first placement groove and two first limiting grooves. After the patient turns over, the splint is inserted into the first limiting groove and the screw is inserted into the first placement groove.

[0010] Furthermore, the two clamping plates are Y-shaped, and the driving component includes a connecting cylinder, a double-threaded rod, and two movable plates. The double-threaded rod is rotatably connected to the inside of the connecting cylinder, and the two movable plates are respectively threaded to the two ends of the double-threaded rod. The two movable plates are respectively fixedly connected to the two clamping plates. A fixed airbag is provided on the inner side of the two clamping plates, and an air storage bag is provided between the two movable plates. A connecting pipe is provided between the air storage bag and the fixed airbag.

[0011] Furthermore, each fixed plate is provided with a connecting rod, and both ends of the connecting cylinder are provided with fixed blocks. The bottom of the fixed block is provided with a slot, and the upper end of the connecting rod is provided with an insert block that can be inserted into the slot. The driving component also includes two knobs, one side of which is provided with an insert rod. The insert block is provided with a fixing hole, and the insert rod passes through the fixing hole. The ends of the insert rod and the ends of the double-ended threaded rod are provided with matching connectors for connecting the insert rod and the double-ended threaded rod.

[0012] Furthermore, the two fixation plates are arc-shaped, and auxiliary plates are fixedly connected to the two fixation plates. The two ends of the auxiliary plates are arc-shaped and used to fix the patient's chest.

[0013] Furthermore, sliding plates are slidably connected to both ends of the auxiliary plate along its length. Multiple push plates are spaced apart on the outer side of the sliding plates, and an external airbag is provided between each push plate. When the external airbag is inflated, the sliding plate can bend inward.

[0014] Furthermore, an auxiliary airbag is provided on the inner side of the sliding plate, and a support airbag is provided at the lower end of the sliding plate. When the support airbag is inflated, it can support the patient's back.

[0015] Furthermore, it also includes a support plate, which is L-shaped, and the headrest is located on the support plate;

[0016] The traction assembly includes a slider, a support rod, a rigid rope, a weight, and a pulley. A slide rail is provided on one side of the support plate, the slider is slidably connected to the slide rail, the pulley is located on the top of the support rod, the rigid rope passes around the pulley, and one end of the rigid rope is connected to the traction bow and the other end is connected to the weight.

[0017] Furthermore, a shoulder pillow is provided on one side of the headrest, a second limiting groove is provided on the headrest for placing the head, and a second placement groove is provided on the headrest for placing the traction bow;

[0018] The headrest has multiple through holes spaced apart in the first limiting groove, and each through hole has a telescopic airbag. A support box is provided on the support plate, and the bottom of each telescopic airbag is connected to the support box.

[0019] The beneficial effects of this utility model are as follows:

[0020] In this invention, a special pillow for cranial traction patients can be used with a fixing plate and splint to connect and fix the patient's head, neck, and shoulders, and the installation is simple. Rotating the knob fixes the splint to the patient's head via the insert rod, simultaneously inflating the fixation airbag to fill the gap between the patient's head and the splint, creating a wrapping effect and improving the stability of the splint and the patient's comfort. This ensures that the patient's head, neck, and shoulders remain in a straight line when turning over.

[0021] Furthermore, after the patient turns over, the splint will fall into the first limiting groove for positioning and fixation. This facilitates the positioning of the patient's head after turning over, ensuring that the patient's head, neck, and shoulders remain in a straight line. On the other hand, it facilitates the positioning of the traction bow and the adjustment of the traction mechanism, ensuring that the traction force of the traction mechanism always coincides with the cervical spine axis, thus maintaining cervical spine stability.

[0040] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0041] Reference Figure 1-14 A special pillow for patients undergoing cranial traction is designed to facilitate turning over and ensure that the traction force is always aligned with the cervical spine axis before, during, and after turning over, thus maintaining cervical spine stability.

[0042] This skull traction patient-specific pillow includes a support plate 1, a headrest 2, a traction mechanism, and a fixation mechanism;

[0043] The support plate 1 is L-shaped, and the headrest 2 is mounted on the support plate 1. The support plate 1 is used to fix the headrest 2. A shoulder pillow 3 is also provided on the support plate 1 to support the patient's shoulders and help limit the body position during traction. The headrest 2 is provided with a second limiting groove 202, which is used to limit and fix the patient's head when the patient is lying flat.

[0044] The headrest 2 is made of latex material, which has good support and breathability, and can be used by people of different weights.

[0045] The headrest 2 is provided with a first placement groove 203, a second placement groove 204 and a first limiting groove 201. After the patient turns over, the splint 20 is inserted into the first limiting groove 201, thereby limiting the splint 20 and ensuring the positioning and fixation of the patient's head after turning over. At this time, the screw 13 is inserted into the first placement groove 203 and the traction bow 12 falls into the second placement groove 204, effectively avoiding the influence of the traction bow 12 and the screw 13 after the patient turns over.

[0046] The fixation mechanism is used to connect and stabilize the patient's head, cervical spine, and body when the patient turns over, preventing traction failure or aggravation of injury. The fixation mechanism includes two arc-shaped fixation plates 14 that fit snugly over the patient's shoulders, and the inner side of each fixation plate 14 is provided with a sponge pad 1401. Connecting rods 15 are fixedly connected to the fixation plates 14, and the upper ends of the two connecting rods 15 are connected to connecting sleeves 17 via a plug-in fixing method. The connecting sleeves 17 connect and fix the two fixation plates 14.

[0047] Two clamps 20 are slidably connected to one side of the connecting tube 17. The two clamps 20 can slide close to each other to clamp the two sides of the patient's head. The two clamps 20 are Y-shaped, which facilitates cooperation with the traction bow 12 and avoids affecting the fixation of the traction bow 12. The Y-shaped clamps 20 can form four-point fixation on the patient's head, that is, fix the patient's head in four directions, thereby improving the head fixation effect. Together with the connected fixation plate 14, the patient's shoulders and head are fixed, thereby ensuring that the head, neck, shoulders and torso rotate as a whole when the patient turns over, so as to maintain the stability of the cervical spine and avoid traction failure or aggravation of injury.

[0048] In some embodiments, a fixing airbag 21 is provided on the inner side of the two splints 20. The fixing airbag 21 can be inflated. After inflation, it can fill the gap between the patient's head and the splint 20 to form a wrapping effect, which improves the clamping stability of the splint 20 on the one hand and the patient's comfort on the other.

[0049] Reference Figure 3 and Figure 4 A double-ended threaded rod 22 is rotatably connected inside the connecting cylinder 17. Both ends of the double-ended threaded rod 22 are threadedly connected to movable plates 23. Two clamping plates 20 are fixedly connected to the two movable plates 23 respectively. Rotating the double-ended threaded rod 22 brings the two movable plates 23 closer together, thereby causing the two clamping plates 20 to move closer together. An air reservoir 2102 is located between the two movable plates 23. A connecting tube 2101 connects the air reservoir 2102 and the fixed air bladder 21. When the two clamping plates 20 move closer together, the two movable plates 23 push the air reservoir 2102, thereby forcing the gas inside the air reservoir 2102 into the fixed air bladder 21 through the connecting tube 2101. This causes the fixed air bladder 21 to inflate and fill the gap between the patient's head and the clamping plates 20.

[0050] In some embodiments, refer to Figure 5 and Figure 6The connecting cylinder 17 has fixing blocks 18 on both sides, and the bottom of the fixing blocks 18 has a slot. The upper end of the connecting rod 15 has an insert block 16, which can be inserted into the slot to connect the connecting rod 15 to the fixing blocks 18. The insert block 16 has a fixing hole. The fixing mechanism also includes a knob 19, and one side of the knob 19 is fixedly connected to an insert rod 1901. When installing the fixing mechanism, the insert block 16 can be inserted into the slot of the fixing block 18 first, and then the insert rod 1901 can be inserted horizontally into the fixing hole 1601 of the insert block 16 to fix the insert block 16, so that the fixing plate 14 of the fixing shoulder and the clamp 20 of the fixing head cannot be detached.

[0051] Furthermore, one end of the insertion rod 1901 and the end of the double-ended threaded rod 22 are equipped with a matching connector 1902. When the insertion rod 1901 is inserted, it can be connected to the double-ended threaded rod 22 via the connector 1902. Rotating the knob 19 will then rotate the insertion rod 1901, thereby rotating the double-ended threaded rod 22 and fixing the splint 20 to the patient's head. The connector 1902 can be a magnetic connector to prevent the insertion rod 1901 from falling out. Magnetic connectors are existing technology and will not be described further.

[0052] In some embodiments, refer to Figure 7-10 Each fixed plate 14 has an auxiliary plate 25 on one side, and a sliding groove on the auxiliary plate 25. A movable block 26 is slidably connected inside the sliding groove. A sliding plate 28 is provided on one side of the movable block 26. Both the auxiliary plate 25 and the sliding plate 28 are arc-shaped and fit against the outer side of the patient's chest. The sliding plate 28 can be moved by the movable block 26, thereby moving the sliding plate 28 towards the patient's back, so that one end of the arc-shaped sliding plate 28 reaches the patient's back, and works with the auxiliary plate 25 to wrap around both sides of the patient's chest.

[0053] The movable block 26 is provided with an inflation port 27, and the inner side of the sliding plate 28 is provided with an auxiliary airbag 29. The inflation port 27 is connected to the auxiliary airbag 29. By inflating the inflation port 27, gas can enter the auxiliary airbag 29 inside the sliding plate 28. The auxiliary airbag 29 expands, thereby fixing the auxiliary plate 25 and the sliding plate 28 to the outside of the patient's chest, and fixing the fixation plate 14 firmly to the patient's shoulder.

[0054] The bottom end of the sliding plate 28 is provided with a support airbag 30. The auxiliary airbag 29 is connected to the support airbag 30. When the airbag is inflated through the inflation port 27, the gas will enter the interior of the support airbag 30 and cause it to expand. Since one end of the sliding plate 28 allows the support airbag 30 to be inserted under the patient's back, when the support airbag 30 expands, it can lift one side of the patient's body upwards to assist the patient in turning over.

[0055] In some embodiments, refer to Figure 11The sliding plate 28 is made of flexible material and can be bent. The outer side of the sliding plate 28 is provided with multiple spaced push plates 2801. An external air bladder 2802 is provided between every two push plates 2801. The external air bladders 2802 are connected to each other. When the external air bladders 2802 are inflated, the external air bladders 2802 expand, thereby pushing the push plates 2801, causing the outer side of the sliding plate 28 to extend, thereby causing the sliding plate 28 to bend inward and fit against the outer side of the patient's chest to accommodate patients of different body types.

[0056] Reference Figure 2 The traction mechanism includes a traction bow 12, a rigid rope 8, and a support rod 7. Screws 13 are provided on the traction bow 12 for fixing it to both sides of the patient's head. One end of the traction bow 12 is connected to the rigid rope 8, and a weight 9 is attached to the other end of the rigid rope 8. A pulley 10 is provided at the top of the support rod 7 to support the rigid rope 8, allowing the weight 9 to pull the traction bow 12 through the rigid rope 8.

[0057] In some embodiments, refer to Figure 2 The top of the support rod 7 is provided with a horizontal guide cylinder 11, through which the rigid rope 8 passes to facilitate observation of whether the rigid rope 8 is horizontal and whether the traction force coincides with the cervical spine axis.

[0058] In some embodiments, a slide rail 5 is provided on one side of the support plate 1, and a slider 6 is provided at the bottom of the support rod 7. The traction mechanism can be moved as a whole by sliding the slider 6 inside the slide rail 5. When the patient turns over, the head position shifts, and the traction mechanism can be moved at the same time, so that the traction force of the traction mechanism always coincides with the cervical spine axis, maintaining cervical spine stability.

[0059] In some embodiments, the top of the support rod 7 is provided with a telescopic rod. By extending and retracting the telescopic rod, the height of the pulley 10 can be adjusted, thereby allowing for flexible adjustment according to the height position of the traction bow 12. This ensures that the traction force of the traction bow 12 always coincides with the cervical spine axis, maintaining cervical spine stability. The telescopic rod is existing technology and will not be described in detail here.

[0060] Reference Figure 12 and Figure 13 The headrest 2 is provided with a first limiting groove 201, which is adapted to the shape of the splint 20. When the patient turns over, the splint 20 falls into the first limiting groove 201, thereby limiting the splint 20. This facilitates the positioning of the patient's head after turning over, ensuring that the patient's head, neck, and shoulders are always in a straight line. On the other hand, it facilitates the positioning of the traction bow 12 and the adjustment of the traction mechanism, ensuring that the traction force of the traction mechanism always coincides with the cervical spine axis, maintaining cervical spine stability.

[0061] The bottom of the first limiting groove 201 is also provided with multiple through holes, and the inside of the through holes is provided with telescopic airbags 4. The bottom of the headrest 2 is provided with a support box 401, and the telescopic airbags 4 are connected to the support box 401. When the patient turns over, the weight of the head is supported by the first limiting groove 201 of the headrest 2. In order to avoid the headrest 2 from deforming due to prolonged pressure, the head is supported by telescopic airbags 4. Each telescopic airbag 4 is connected to each other through the support box 401, so as to adapt to the arc-shaped splint 20 structure.

[0062] The headrest 2 is provided with a first placement slot 203 and a second placement slot 204, into which screws 13 and traction bows 12 can be placed respectively after the patient turns over.

[0063] The support box 401 can also pump in or expel air, causing the telescopic airbag 4 to rise or fall as a whole, thereby ensuring that the head, neck and shoulders of patients with different head circumferences are always in a straight line when using it.

[0064] The working principle of this special pillow for cranial traction patients is as follows: The patient's head, neck, and shoulders are connected and fixed by the cooperation of the fixing plate 14 and the splint 20. Installation is simple: inserting the insert block 16 into the slot connects the connecting rod 15 to the fixing block 18. Then, inserting the insert rod 1901 limits and fixes the insert block 16, preventing the fixing plate 14 for the shoulder from separating from the splint 20 for the head. Finally, rotating the knob 19 fixes the splint 20 to the patient's head via the insert rod 1901, simultaneously inflating the fixation airbag 21 to fill the gap between the patient's head and the splint 20, creating a wrapping effect and improving the stability of the splint 20 and patient comfort. This ensures that the patient's head, neck, and shoulders remain in a straight line when turning over.

[0065] Furthermore, after the patient turns over, the traction mechanism can move synchronously via slider 6 to ensure that the traction force always coincides with the cervical spine axis before and after the patient turns over, thus maintaining cervical spine stability.

[0066] After the patient turns over, the splint 20 falls into the first limiting groove 201 for positioning and fixation, facilitating adjustments to the position of the traction mechanism and ensuring that the traction force of the traction mechanism always coincides with the cervical spine axis. Furthermore, the telescopic airbag 4 supports the head, preventing head displacement caused by deformation of the headrest 2 due to the weight of the head. This ensures that the patient's head, neck, and shoulders remain in a straight line at all times.

[0067] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
