Description

Technical Field

[0001] This invention belongs to the field of medical assessment device technology, and in particular relates to a controllable pain stimulation component and a special instrument for pain assessment of patients with traumatic brain injury and impaired consciousness. Background Technology

[0002] Patients with impaired consciousness after traumatic brain injury are unable to accurately express their pain sensations verbally. Clinically, the degree of consciousness recovery is often assessed by applying pain stimuli and observing the patient's facial expressions, limb movements, and other responses. Common pain stimulation methods include pressing the nail bed, pricking the skin with a needle, or gently pressing the limb with a blunt instrument.

[0003] Existing pain stimulation tools cannot adjust the stimulation intensity, which can easily lead to situations where the intensity is too high and injures the patient, or too low and fails to achieve the desired stimulation effect. In addition, most tools can only stimulate a single area, resulting in poor adaptability. Furthermore, the accompanying assessment equipment is inconvenient to operate, and devices such as mobile phones used to capture patient expressions are difficult to place. Therefore, a controllable pain stimulation component and a special pain assessment device for patients with traumatic brain injury and impaired consciousness are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a controllable pain stimulation component and a special instrument for pain assessment of patients with traumatic brain injury and impaired consciousness. It can adjust the stimulation intensity, is flexible in use, and is easy to operate, thus solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: A controllable pain stimulation component includes: a first clamping rod and a second clamping rod. Fixing plates are fixedly installed on both sides of the end of the first clamping rod. An arc-shaped first slide rail is provided on one side of each fixing plate. A slide rod is slidably connected between the first slide rails. The second clamping rod rotates around the circumference of the slide rod. A slider is slidably connected within each of the first slide rails. Two arc-shaped guide rods are fixedly connected to one side of each slide rod. The guide rods slidably pass through the sliders. A first spring is sleeved around the circumference of each guide rod, and the two ends of the first spring abut against the slider and the slide rod, respectively. An adjustment section, located between two fixed plates, is used to adjust the compression level of the first spring.

[0006] Furthermore, the adjustment part includes a first rotating shaft and a second rotating shaft. The first rotating shaft is rotatably connected between two sliders, and the second rotating shaft is rotatably connected between the ends of two fixed plates. A through screw is rotatably connected to one side of the second rotating shaft, and the screw thread passes through the first rotating shaft.

[0007] Furthermore, a fixing cylinder is fixedly connected to one end of both the first clamping rod and the second clamping rod. The fixing cylinder is used to extend the first clamping rod and the second clamping rod, and the fixing cylinders have the same structure.

[0008] Furthermore, one end of the fixed cylinder is open and an impact rod is slidably connected inside. One end of the impact rod is fixedly connected to a blunt needle, and the other end of the impact rod is fixedly installed with a second spring between it and the inner wall of the fixed cylinder. A second slide is provided on one side of the fixed cylinder, and a sliding plate is slidably connected inside the second slide. The sliding plate is fixed to the impact rod.

[0009] Furthermore, a mounting groove is provided on the side of the second clamping rod near the first clamping rod, and a fixed shaft is fixedly connected in the mounting groove, with a pressure sleeve sliding around the circumference of the fixed shaft.

[0010] Furthermore, the fixed shaft is circumferentially fitted with two silicone sleeves, the two ends of which contact the mounting groove and the pressure sleeve, respectively.

[0011] The present invention also proposes a special device for pain assessment of patients with traumatic brain injury and impaired consciousness, including a controllable pain stimulation component and a trolley, with a placement box fixedly connected to one side of the trolley, and the controllable pain stimulation component located in the placement box.

[0012] Furthermore, a sleeve is fixedly connected to one side of the trolley. The top of the sleeve is open and a rod slides inside. A guide sleeve is fixedly connected to the top of the rod. A horizontally arranged crossbar is slidably connected inside the guide sleeve. A fixed seat is fixedly connected to one end of the crossbar. A mobile phone holder is rotatably installed on one side of the fixed seat via a damping shaft. A through-hole set screw is threaded to one side of the guide sleeve, and the set screw abuts against the crossbar.

[0013] Furthermore, one side of the insertion rod is provided with multiple equally spaced slots, and one side of the trolley is rotatably connected to a rotating rod. The top of the rotating rod is fixedly connected to a card plate that cooperates with the slots, and the bottom of the rotating rod is fixedly connected to a push plate. A torsion spring is fixedly installed between the rotating rod and the trolley.

[0014] Furthermore, a piston is fixedly connected to the bottom of the insertion rod, the piston slides inside the sleeve, a one-way air intake valve is fixedly connected to one side of the bottom of the sleeve, and an exhaust hole is provided on one side of the bottom of the sleeve to control the exhaust speed.

[0015] The embodiments of the present invention have the following beneficial effects: In this invention, by using the screw and the first rotating shaft in combination, and by setting the first spring and the slider, rotating the screw can drive the slider to move along the first slide, precisely changing the compression degree of the first spring, thereby realizing continuous adjustment of the clamping force between the first clamping rod and the second clamping rod. This allows for flexible adjustment of the stimulation intensity according to the patient's tolerance, avoiding injury to the human body or insufficient stimulation due to improper clamping force.

[0016] In this invention, by using the sliding plate, the impact rod, and the second spring in combination, the sliding plate is pushed backward to compress the second spring. After the spring is released, it pushes the blunt needle to pop out quickly and contact the patient's skin, producing a brief and controllable stinging sensation. This facilitates standardized stimulation of different parts of the patient's body, such as limbs and torso, and improves the repeatability and ease of operation of pain assessment.

[0017] In this invention, by using the slot, plate, torsion spring, crossbar and set screw on the insertion rod, the foot can push the push plate to release the lock and adjust the height of the insertion rod. After being released, it automatically snaps into the slot to complete the positioning. At the same time, the crossbar can slide horizontally and be fixed with the set screw, realizing the rapid adjustment of the phone holder in the height and horizontal direction, which is convenient for stable shooting of the patient's facial expression changes.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0024] In one embodiment, please refer to Figures 1-8As shown, this embodiment provides a controllable pain stimulation component, including: a first clamping rod 1 and a second clamping rod 2. Fixing plates 4 are fixedly installed on both sides of the end of the first clamping rod 1. An arc-shaped first slide rail 15 is provided on one side of each fixing plate 4. The two first slide rails 15 have the same curvature and size. A slide rod 8 is slidably connected between the first slide rails 15. Both ends of the slide rod 8 extend into the interior of the two first slide rails 15, allowing it to slide smoothly along the arc-shaped trajectory of the first slide rails 15. The second clamping rod 2 is rotatably sleeved on the outer circumference of the slide rod 8. The second clamping rod 2 can rotate freely around the axis of the slide rod 8, allowing the first clamping rod 1 and the second clamping rod 2 to be relatively... The mechanism is designed for easy clamping of the patient's fingers. Sliding blocks 9 are slidably connected within the first slide rail 15, their dimensions matching the first slide rail 15. Two arc-shaped guide rods 10 are fixedly connected to one side of the slide rod 8, their curvature matching the curvature of the first slide rail 15. The two guide rods 10 slide through their corresponding sliding blocks 9. Each sliding block 9 has a through hole that matches the guide rod 10. A first spring 11 is fitted around the circumference of each guide rod 10, with both ends of the first spring 11 abutting against the sliding block 9 and the slide rod 8, respectively. When the sliding block 9 slides along the guide rod 10, the compression degree of the first spring 11 changes, thereby adjusting the force exerted by the first spring 11 on the slide rod 8. An adjustment section is provided between the two fixed plates 4 to adjust the compression degree of the first spring 11, thus controlling the clamping force of the first clamping rod 1 and the second clamping rod 2 on the patient's body parts.

[0025] The adjustment unit includes a first rotating shaft 12 and a second rotating shaft 13. The first rotating shaft 12 is rotatably connected between two sliders 9, and the second rotating shaft 13 is rotatably mounted between the ends of two fixed plates 4. A through screw 14 is rotatably connected to one side of the second rotating shaft 13. The screw 14 is threadedly engaged with the second rotating shaft 13. The end of the screw 14 away from the second rotating shaft 13 is threaded through the first rotating shaft 12. When the screw 14 is rotated, it moves relative to the second rotating shaft 13, thereby driving the first rotating shaft 12 to move along the direction of the guide rod 10. When the first rotating shaft 12 moves, it drives the two sliders 9 to slide synchronously. During the sliding process, the sliders 9 are squeezed or released. The first spring 11 is used to adjust the degree of compression of the first spring 11, thereby controlling the magnitude of the clamping force. When stimulating the patient's pain, the patient's finger is placed between the first clamping rod 1 and the second clamping rod 2, and the patient holds the subsequently set fixed cylinder 3 and brings it close. The finger can be stimulated by the first clamping rod 1 and the second clamping rod 2. At the same time, rotating the screw 14 can move the first rotating shaft 12, which drives the slider 9 to move, thereby changing the degree of compression of the first spring 11 and controlling the clamping force. During the clamping process, the slide rod 8 will be displaced along the first slide rail 15 to avoid excessive clamping force that could cause finger injury.

[0026] A fixing cylinder 3 is fixedly connected to one end of the first clamping rod 1 and the second clamping rod 2. The fixing cylinder 3 is made of hollow metal tube, and its length can be set according to actual usage requirements. The fixing cylinder 3 is used to extend the first clamping rod 1 and the second clamping rod 2, making it convenient for operators to hold and operate. The two fixing cylinders 3 have the same structure.

[0027] One end of the fixed cylinder 3 is open and an impact rod 16 is slidably connected inside. The size of the impact rod 16 is adapted to the inner diameter of the fixed cylinder 3, allowing it to slide inside the fixed cylinder 3 without significant wobbling. A blunt needle 19 is fixedly connected to one end of the impact rod 16, and a second spring 20 is fixedly installed between the other end of the impact rod 16 and the inner wall of the fixed cylinder 3. When the second spring 20 is in its natural state, the end of the blunt needle 19 is flush with or located inside the open end of the fixed cylinder 3. A second slide rail 17 is provided on one side of the fixed cylinder 3, and the second slide rail 17 is set along the length of the fixed cylinder 3. A sliding plate 18 is slidably connected inside the second slide rail 17. One side of the sliding plate 18 extends into the interior of the fixed cylinder 3 and is fixed to the impact rod 16. Pushing the sliding plate 18 can drive the impact rod 16 to move synchronously. In another examination method, the end of the fixed cylinder 3 is brought into contact with the human body, the slide plate 18 is moved, which in turn drives the impact rod 16 and the blunt needle 19 away from the human body. After the slide plate 18 is released, the blunt needle 19 is pushed into contact with the human body under the action of the second spring 20, which facilitates stimulation of other parts of the human body and meets the pain stimulation needs of different parts.

[0028] In another embodiment: refer to Appendix Figures 1-8 A controllable pain stimulation component includes a second clamping rod 2 with a mounting groove on the side near the first clamping rod 1. The size of the mounting groove is adapted to subsequent components. A fixed shaft 5 is fixedly connected inside the mounting groove. A pressure sleeve 6 is slidably fitted around the circumference of the fixed shaft 5. The pressure sleeve 6 is made of wear-resistant plastic and can slide and rotate freely around the axis of the fixed shaft 5. Two silicone sleeves 7 are fitted around the circumference of the fixed shaft 5, located on both sides of the pressure sleeve 6. The two ends of the silicone sleeves 7 contact the inner wall of the mounting groove and the end face of the pressure sleeve 6, respectively. The silicone sleeves 7 have good elasticity and cushioning performance, and can play a buffering role between the pressure sleeve 6 and the mounting groove. When clamping the patient's finger, the pressure sleeve 6 can move accordingly as the second clamping rod 2 rotates, further avoiding damage to the patient.

[0029] This pain assessment device for patients with traumatic brain injury and impaired consciousness includes the aforementioned controllable pain stimulation component and a trolley 21 with casters with brakes at the bottom for easy pushing and securing. A placement box 22 is fixedly connected to one side of the trolley 21. The placement box 22 is made of plastic or metal and the controllable pain stimulation component is placed inside the placement box 22 for easy storage and retrieval.

[0030] A sleeve 23, made of hollow metal tubing, is fixedly connected to one side of the trolley 21. The sleeve 23 has an open top with a sliding insert 25 inside. A guide sleeve, also hollow, is fixedly connected to the top of the insert 25, with a horizontally slidable crossbar 26 inside. The crossbar 26 can slide left and right along the length of the guide sleeve. A fixing seat 29 is fixedly connected to one end of the crossbar 26. A phone holder 30 is rotatably mounted on one side of the fixing seat 29 via a damping pivot. The phone holder 30 can rotate freely around the damping pivot, facilitating adjustment of the phone's shooting angle. A through-hole set screw 27 is threaded onto one side of the guide sleeve. One end of the set screw 27 extends into the guide sleeve and abuts against the crossbar 26. Once the crossbar 26 is adjusted to the appropriate position, tightening the set screw 27 secures the crossbar 26, preventing it from sliding. In use, push the trolley 21 to the usage position, prepare the mobile phone for taking pictures of the patient's facial expressions, push the subsequently set push plate 35 with your legs or feet, push plate 35 drives the rotating rod 24 to rotate, thereby causing the locking plate 34 to disengage from the locking slot 28, then pull the insertion rod 25 upward, thereby raising the mobile phone holder 30. After it is in place, release the push plate 35, the locking plate 34 is reset under the action of the torsion spring 36, and re-locks into the locking slot 28 to complete the positioning of the insertion rod 25. Then put the mobile phone into the mobile phone holder 30, pull the crossbar 26 to move the mobile phone above the patient, adjust the angle, tighten the set screw 27 to fix the crossbar 26, and you can take pictures to record the patient's facial expressions after being stimulated by pain, providing a basis for pain assessment.

[0031] Multiple equally spaced slots 28 are provided on one side of the insertion rod 25. The slots 28 are evenly arranged along the length of the insertion rod 25. A rotating rod 24 is rotatably connected to one side of the trolley 21. A locking plate 34 that works with the slots 28 is fixedly connected to the top of the rotating rod 24. The size of the locking plate 34 is adapted to the slots 28 so that it can be locked into the slots 28 for positioning. A push plate 35 is fixedly connected to the bottom of the rotating rod 24 so that the operator can push it with their legs or feet. A torsion spring 36 is fixedly installed between the rotating rod 24 and the trolley 21. The torsion spring 36 is sleeved on the outside of the rotating shaft of the rotating rod 24. When the push plate 35 is pushed to rotate the rotating rod 24, the torsion spring 36 will deform and generate elastic force. After the push plate 35 is released, the elastic force of the torsion spring 36 will drive the rotating rod 24 to return to its original position, thereby causing the locking plate 34 to be locked into the slots 28, realizing the rapid positioning of the insertion rod 25. The operation is convenient and efficient.

[0032] A piston 31 is fixedly connected to the bottom of the insertion rod 25. The piston 31 is made of rubber and contacts the inner wall of the sleeve 23. The piston 31 slides inside the sleeve 23 and can move up and down inside the sleeve 23. A one-way air intake valve 32 is fixedly connected to one side of the bottom of the sleeve 23. The one-way air intake valve 32 only allows air to enter the sleeve 23 from the outside. An exhaust hole 33 is opened on one side of the bottom of the sleeve 23. The exhaust hole 33 is used to control the exhaust speed. When the insertion rod 25 is pulled upward, the piston 31 moves upward, and a negative pressure is formed inside the sleeve 23. External air enters the sleeve 23 through the one-way air intake valve 32. When the insertion rod 25 is pushed downward, the piston 31 moves downward, and the air inside the sleeve 23 is discharged through the exhaust hole 33. By controlling the exhaust speed of the exhaust hole 33, the descent process of the insertion rod 25 can be made more stable, avoiding the phone on the phone holder 30 from shaking or falling due to the rapid descent of the insertion rod 25, and further improving the stability of use.

[0033] The usage process and working principle of the technical solution of this invention are as follows: When in use, push the cart 21 to the use position. First, prepare a mobile phone to take pictures of the patient's facial expressions. Push the push plate 35 with your legs or feet. The push plate 35 drives the rotating rod 24 to rotate, which in turn drives the locking plate 34 to disengage from the slot 28. Then pull the insertion rod 25 upward to raise the mobile phone holder 30. After it is in place, release the push plate 35. The locking plate 34 resets under the action of the torsion spring 36 and re-locks into the slot 28 to complete the positioning of the insertion rod 25. Then put the mobile phone into the mobile phone holder 30, pull the crossbar 26 to move the mobile phone above the patient, and adjust the angle to take pictures. During stimulation, the patient's finger is placed between the first clamping rod 1 and the second clamping rod 2, and then the fixed cylinder 3 is grasped and brought closer to stimulate the finger. At the same time, the patient's facial expression is recorded. By rotating the screw 14, the first rotating shaft 12 can be moved, which drives the slider 9 to move, thereby changing the compression degree of the first spring 11 and thus controlling the clamping force. During the clamping process, the slider 8 is displaced to avoid finger injury. In another examination method, the end of the fixed cylinder 3 is brought into contact with the human body, and the sliding plate 18 is moved, which in turn moves the impact rod 16 and the blunt needle 19 away from the human body. After the sliding plate 18 is released, the blunt needle 19 is pushed into contact with the human body by the action of the second spring 20, which facilitates stimulation of other parts of the human body.
