Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a writing pen with a pain scoring function. Background Art

[0002] In medical clinical practice, especially in scenarios such as the emergency department and wards where the condition of patients needs to be quickly evaluated, medical staff often need to timely and accurately evaluate the pain level of patients. At present, pain assessment mainly relies on the subjective description of patients combined with the experience judgment of medical staff. Common tools include the Visual Analogue Scale (VAS), Numerical Rating Scale (NRS), etc. However, these methods usually require additional assessment tools (such as scoring cards or electronic devices) and manual records, which not only take time but also may affect the assessment efficiency due to cumbersome operations.

[0003] In addition, when medical staff write medical records or record pain scores, they often need to frequently switch tools (such as pens, flashlights, pupillometers, etc.), which not only reduces work efficiency but also may affect the rapid response in emergency situations due to the dispersion of tools. Existing writing tools have single functions and cannot meet the requirements for multifunctional integrated devices in medical scenarios. Although there are some pens with integrated lighting functions on the market, their lighting angles are fixed and it is difficult to simultaneously meet the needs of writing supplementary lighting and medical examinations (such as pupil observation or local lighting).

[0004] In terms of refill replacement, traditional writing pens usually have strict requirements on the length of the refill. If the refill is too long or too short, it may lead to abnormal use. In the prior art, although some writing tools are designed with a structure that can adjust the telescopic length of the refill, their adjustment mechanisms are complex and lack effective protection for the nib, which is prone to damage to the nib or drying up of the ink.

[0005] Therefore, there is an urgent need for a medical special tool that integrates functions of writing, pain assessment, lighting, and data recording to solve problems such as scattered functions, cumbersome operations, and poor refill adaptability in the prior art. The writing pen with a pain scoring function proposed by the present invention combines medical functions with a writing tool through a mechanical-electronic integrated design, which can significantly improve the work efficiency and assessment accuracy of medical staff.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Invention

[0007] To solve the above problems, the purpose of the present invention is to provide a writing pen with a pain scoring function, which integrates medical functions such as pain assessment, pupil observation, and data recording into a conventional writing tool through a mechanical-electronic integrated design, and is particularly suitable for use in scenarios such as the emergency department and wards that require rapid assessment.

[0008] To achieve the above object, the present invention provides a writing pen with a pain scoring function. The writing pen includes a pen body, and the pen body includes a pen case. A writing sticker and a flashlight are installed on the pen case, and a pain scale is provided on the pen case.

[0009] A fixing cylinder is fixed to the upper end of the pen case. The flashlight includes a mounting shaft, and the mounting shaft is threadedly connected to the fixing cylinder. A lamp body is installed on the mounting shaft, and a rotating ring is provided on the lamp body. First rotating shafts are vertically provided on both sides of the pen case, telescopic rods are vertically fixed on the first rotating shafts, second rotating shafts are fixed on the telescopic rods, and the second rotating shafts are rotatably connected to the rotating ring.

[0010] Furthermore, a pen core is installed in the pen case, a limiting ring is fixed in the pen case, a first spring is fixed above the limiting ring, sliding grooves are formed on the inner walls of both sides of the pen case, the pen body further includes a mounting plate, sliding blocks adapted to the sliding grooves are fixed on both sides of the mounting plate, a limiting sleeve is fixed below the mounting plate, a triangular block is fixed above, a rubber layer is provided on the inner wall of the limiting sleeve, and the upper end of the pen core is inserted into the limiting sleeve.

[0011] A threaded hole is formed in the pen case, a lead screw is installed in the threaded hole, a driving knob is fixed to one end of the lead screw, a spherical block is fixed to the other end, and the spherical block corresponds to the inclined surface of the triangular block.

[0012] Furthermore, a pen clip is installed on the pen case, and an electronic watch is installed on the pen clip.

[0013] Furthermore, the pain scale includes pain level scales, and a note for marking the facial expressions and symptoms of patients at the corresponding pain levels is provided on one side of the pain level scales.

[0014] Furthermore, a limiting groove is formed in the upper end of the pen case.

[0015] The writing sticker includes a sleeve sleeved on the fixing cylinder, a winding drum is rotatably provided on the sleeve, a notepad is wound on the winding drum, a limiting rod is fixed to the free end of the notepad, a limiting block adapted to the limiting groove is fixed below the sleeve, a sliding shaft perpendicular to the axis of the sleeve is slidably provided on the limiting block, an L-shaped limiting strip is fixed on the sliding shaft, and a second spring is fixedly connected between the limiting strip and the sleeve.

[0016] Furthermore, a limiting hole is formed in the pen case, a limiting shaft is fixed on the limiting strip, and when the limiting block is inserted into the limiting groove, the limiting shaft is inserted into the limiting hole under the action of the second spring.

[0021] 2. The flashlight in the writing pen of the present invention adopts multi-axis adjustment, so that the flashlight can not only be used for illumination when detecting the body parts of patients, but also be used for filling light at the writing position during writing.

[0022] 3. When the rotation drive knob is rotated, the wire pushes the spherical block to squeeze the inclined surface of the triangular block, and the triangular block drives the mounting plate to move downward along the chute, compressing the first spring. The rubber layer of the limit sleeve clamps the pen core and moves downward synchronously, so that the tip of the pen core extends out of the pen case for writing, enabling the pen case to be applicable to pen cores of different lengths, thereby reducing the requirements for its length when replacing the pen core. When the drive knob is rotated in the reverse direction, the first spring rebounds and resets, and the tip of the pen core retracts into the pen case, realizing the hiding of the tip.

[0039] The pain scale 2 includes pain level graduations, and on one side of the pain level graduations, there are remarks for marking the facial expressions and symptoms of the patient at the corresponding pain levels.

[0040] A pen core 12 is installed inside the pen case 11. As Figure 2 , Figure 3 shown, a limiting ring 13 is fixed inside the pen case 11. A first spring 18 is fixed above the limiting ring 13. Sliding grooves 14 are formed on both inner walls of the pen case 11. The pen body 1 further includes a mounting plate 15. Sliders 16 adapted to the sliding grooves 14 are fixed on both sides of the mounting plate 15. A limiting sleeve 17 is fixed below the mounting plate 15, and a triangular block 19 is fixed above. A rubber layer is provided on the inner wall of the limiting sleeve 17. The upper end of the pen core 12 is inserted into the limiting sleeve 17.

[0041] The pen case 11 is provided with a threaded hole 110. A lead screw 112 is installed in the threaded hole 110. One end of the lead screw 112 is fixed with a driving knob 111, and the other end is fixed with a spherical block 113. The spherical block 113 corresponds to the inclined surface of the triangular block 19. The upper end of the pen case 11 is fixed with a fixed cylinder 114, as Figure 4 , Figure 5 shown. A limiting groove 115 is opened at the upper end of the pen case 11.

[0042] The writing notepad 4 includes a sleeve 41 sleeved on the fixed cylinder 114, as Figure 6 shown. A winding drum 42 is rotatably arranged on the sleeve 41. A notepad paper 43 is wound on the winding drum 42. A limiting rod (not marked in the figure) is fixed at the free end of the notepad paper 43. A limiting block 44 adapted to the limiting groove 115 is fixed below the sleeve 41. A sliding shaft 45 perpendicular to the axis of the sleeve 41 is slidably arranged on the limiting block 44. An L-shaped limiting strip 46 is fixed on the sliding shaft 45. A second spring (not marked in the figure) is fixedly connected between the limiting strip 46 and the sleeve 41. Under the action of the second spring, the limiting strip 46 presses on the notepad paper 43 to prevent it from loosening.

[0043] The pen case 11 is provided with a limiting hole 115. A limiting shaft 47 is fixed on the limiting strip 46. When the positioning block 44 is inserted into the limiting groove 115, under the action of the second spring, the limiting shaft 47 is inserted into the limiting hole 115. A handle 48 is fixed on the winding drum 42.

[0044] The pen case 11 is provided with a pupil comparison table 6. The pupil comparison table 6 includes pupil size scales. On one side of the pupil size scales, there are standard circular diagrams of pupils corresponding to the scales.

[0045] The flashlight 5 includes a mounting shaft 51. The mounting shaft 51 is threadedly connected with the fixed cylinder 114. A lamp body 52 is installed on the mounting shaft 51. A rotating ring 56 is arranged on the lamp body 52. First rotating shafts 53 are vertically arranged on both sides of the pen case 11. An expansion rod 54 is vertically fixed on the first rotating shaft 53. A second rotating shaft 55 is fixed on the expansion rod 54. The second rotating shaft 55 is rotatably connected with the rotating ring 56.

[0046] The connection between the second rotating shaft 55 and the rotating ring 56, the output shaft of the expansion rod 54 and the shaft sleeve, and the first rotating shaft 53 and the pen case 11 are all in damping fit.

[0047] Working principle: The pain scale 2 adopts the principle of the visual analogue scale (VAS). The patient determines the pain level by comparing their own symptoms with the facial expressions / symptom descriptions (such as "frowning / mild stabbing pain" to "crying / severe pain") marked beside the scales.

[0048] The pupil comparison table 6 is used in conjunction with the flashlight 5. After irradiating the patient's eyes with the lamp body 52, the observed pupil size is compared with the standard circular diagram on the scale to achieve a rapid assessment of the pupil diameter.

[0049] The telescopic mechanism of the pen refill 12: When the rotary drive knob 111 is rotated, the lead screw 112 pushes the spherical block 113 to squeeze the inclined surface of the triangular block 19. The triangular block 19 drives the mounting plate 15 to move downward along the sliding groove 14, compressing the first spring 18. The rubber layer of the limit sleeve 17 clamps the pen refill 12 and moves downward synchronously, so that the tip of the pen refill 12 extends out of the pen case 11 for writing. This enables the pen case 11 to be suitable for pen refills 12 of different lengths, thereby reducing the requirements for the length of the pen refill 12 when replacing it. When the drive knob 111 is rotated in the reverse direction, the first spring 18 rebounds and resets, and the tip of the pen refill 12 retracts into the pen case 11 to achieve the hiding of the tip.

[0050] Fixing of the notepad paper 43 in the writing notepad 4: The limiting strip 46 presses the notepad paper 43 tightly on the surface of the winding drum 42 through the pressure of the second spring, and the limiting shaft 47 is inserted into the limiting hole 115 to form a double lock.

[0051] Taking the writing notepad 4: First, remove the mounting shaft 51 from the fixed cylinder 114, and then take the writing notepad 4 off the fixed cylinder 114. When pulling the limiting rod to unfold the notepad paper 43, the winding drum 42 generates a rotational damping. After releasing, the limiting strip 46 automatically presses tightly to prevent rewinding.

[0052] The flashlight 5 adopts multi-axis adjustment: The first rotating shaft 53 provides a ±90° vertical rotation. The telescopic rod 54 can be extended by 50 - 100 mm. The second rotating shaft 55 enables the 360° horizontal rotation of the lamp body. The damping torque of each joint is controlled within the range of 0.5 - 1 N·m. This allows the flashlight 5 to be not only used for lighting during the detection of the patient's body parts but also for providing supplementary light to the writing position during writing.

[0053] Illumination function: The lamp body 52 adopts a 3 - level brightness adjustable LED (50 / 100 / 200 lumens)

[0054] The rotating ring 56 can finely adjust the irradiation angle.

[0055] The pen clip 116 is integrated with the electronic watch 3 to achieve the timing assessment function. All movable parts adopt damping cooperation to ensure the stability during medical operations.

[0056] The notepad paper 43 adopts a medical - grade waterproof material and can record assessment data. This writing pen, through a mechanical - electronic integrated design, integrates medical functions such as pain assessment, pupil observation, and data recording into a conventional writing tool, and is especially suitable for use in scenarios that require rapid assessment such as emergency departments and wards.
