Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to an anti-drop type blood oxygen saturation finger clip. Background Art

[0002] The ECG monitoring blood oxygen saturation meter is a medical device that monitors the human body's blood oxygen saturation. It is helpful to understand the patient's hypoxia and promptly detect the patient's hypoxia and other problems. At present, the ECG monitoring blood oxygen saturation meter includes a host and a blood oxygen probe connected to the host. The blood oxygen probe is mostly finger-clip type, worn on the end of the patient's finger, so that the patient's blood oxygen saturation is displayed on the display screen of the host. However, after the blood oxygen probe is worn on the end of the patient's finger, it is very easy for the patient to break free. For example, the patient accidentally rubs off the blood oxygen probe during sleep, which leads to interruption of blood oxygen saturation monitoring, resulting in the lack of important parameters for ECG monitoring and failure to detect changes in the patient's condition in time, and even serious consequences. Summary of the invention

[0003] The present invention aims to provide an anti-dropping blood oxygen saturation finger clip to solve the problem that the existing finger clip type blood oxygen probe is easy to drop off.

[0004] In order to achieve the above-mentioned purpose, the scheme of the present invention is as follows: an anti-drop type blood oxygen saturation finger clip, comprising a finger clip body, and also comprising a finger ring sleeve and a wrist sleeve, a connecting component is provided between the finger clip body and the finger ring sleeve, the connecting component comprises a movable block, a fixed block and a connecting rod, one end of the connecting rod is rotatably connected to the movable block, the other end of the connecting rod is provided with a threaded section, the fixed block is provided with a threaded through hole I threadedly connected to the threaded section, the fixed block is fixedly connected to the finger ring sleeve, and the movable block is connected to the finger clip body through a connecting rope; one end of the wrist sleeve is detachably connected to the other end of the wrist sleeve, a D-shaped buckle is fixedly connected to the wrist sleeve, a tensioning piece is provided between the finger ring sleeve and the wrist sleeve, a Velcro male surface and a Velcro female surface are provided on the tensioning piece, one end of the tensioning piece is fixedly connected to the finger ring sleeve, and after the other end of the tensioning piece passes through the D-shaped buckle, the Velcro male surface on the tensioning piece is adhered to the Velcro female surface.

[0005] The working principle and beneficial effect of this scheme are as follows: in this scheme, the finger ring sleeve is connected to the finger clamp body through the connecting assembly, and is connected to the wrist cuff through the tensioning member, so that the finger ring sleeve is put on the patient's finger, the finger clamp body is clamped on the fingertip of the finger, and the wrist cuff is worn on the patient's wrist. Under the restriction of the connecting assembly and the tensioning member, the positions of the finger ring sleeve and the finger clamp body are fixed, which can effectively prevent the finger clamp body from falling off from the patient's fingertip. In addition, when the connecting assembly connects the finger ring sleeve and the finger clamp body, the threaded section of the connecting rod is threadedly connected to the threaded through hole I of the fixing block, and the distance between the finger ring sleeve and the finger clamp body can be adjusted by rotating the connecting rod, ensuring that the finger ring sleeve can cover the patient's proximal interphalangeal joint, effectively restricting the flexion and extension movement of the patient's finger, preventing the patient's finger from bending and detaching from the finger clamp body, and further preventing the finger clamp body from falling off.

[0006] Moreover, in this solution, the length of the tensioning member is adjustable, that is, the distance between the wristband and the finger ring is adjustable. Furthermore, the distance between the finger ring and the finger clip body is adjustable, and the wristband can be matched with the thickness of the patient's wrist. Therefore, this solution is applicable to hands within a certain range of length and has good applicability. In addition, in this solution, the existing finger clip type blood oxygen probe can be utilized without a large number of structural improvements. The cost of remodeling old items is low, which is conducive to promotion and use.

[0007] Optionally, a top sheet is provided inside the finger ring sleeve, a raised portion is provided on the outer wall of the finger ring sleeve, a threaded through hole II communicating with the interior of the finger ring sleeve is opened on the raised portion, an adjusting screw is threadedly connected to the threaded through hole II, and one end of the adjusting screw located inside the finger ring sleeve is rotatably connected to the top sheet.

[0008] In this solution, the adjusting screw is rotated to realize the movement of the top sheet in the finger ring sleeve, so that the proximal interphalangeal joints of the patient in the finger ring sleeve are pressed against or pressed tightly, so that the patient can be prevented from bending the proximal interphalangeal joints, or the finger ring sleeve can be further fixed while preventing the patient from bending the proximal interphalangeal joints, thereby further preventing the finger clip body from falling off. In addition, this solution is applicable to fingers of different thicknesses.

[0009] Optionally, the finger clamp body includes an upper finger clamp plate and a lower finger clamp plate, the movable blocks and fixed blocks are both two in number, the two movable blocks are respectively connected to the side walls of the upper finger clamp plate and the lower finger clamp plate by connecting ropes, and the fixed blocks correspond to the movable blocks one by one.

[0010] In this solution, after the threaded section of the connecting rod is threadedly connected to the threaded through hole I of the fixed block, the connecting rope is tightened to apply tension to the upper finger splint and the lower finger splint, thereby effectively preventing the upper finger splint and the lower finger splint from opening and further preventing the finger clamp body from falling off.

[0011] Optionally, there are two tensioning pieces, one of which can be attached to the back of the hand, and the other tensioning piece can be attached to the palm of the hand.

[0012] In this solution, when there are two tensioning members, tension can be better applied to the finger ring sleeve.

[0013] Optionally, one end of the wristband is connected to the other end of the wristband via a Velcro or a belt buckle.

[0014] In this solution, the wristband is detachably connected by means of a Velcro or belt buckle.

[0015] Optionally, an adjustment cap is provided at one end of the adjustment screw located outside the finger ring sleeve.

[0016] In this solution, the design of the adjustment cap makes it easy for the nurse to turn the adjustment screw.

[0017] Optionally, the top sheet is arc-shaped.

[0018] In this solution, when the top sheet is curved, it better fits the shape of the patient's fingers and is more comfortable.

[0019] Optionally, a pressure sensor is provided on the inner bottom wall of the finger ring sleeve or the bottom surface of the top sheet.

[0020] In this solution, a pressure sensor is used to detect the pressure on the patient's proximal interphalangeal joints to prevent the top plate from applying excessive pressure on the proximal interphalangeal joints.

[0021] Optionally, a display screen is provided on the tensioning member, and the display screen is used to display pressure data detected by the pressure sensor.

[0022] In this solution, a display screen is used to display the pressure data detected by the pressure sensor, so that the pressure on the patient's proximal interphalangeal joint can be visualized, making it easier for nurses to adjust the pressure.

[0023] Optionally, a through hole for the connecting rod to pass through is formed on the movable block, and two blocking plates are provided at one end of the connecting rod away from the threaded section, and the two blocking plates are located on both sides of the through hole.

[0024] In this solution, the blocking sheet can prevent the connecting rod from being separated from the movable block. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 1

[0034] This embodiment is basically Figure 1 and Figure 2 As shown: an anti-drop type blood oxygen saturation finger clip, including a finger clip body 1, a finger ring cover 2 and a wrist cover 3, a connecting assembly is provided between the finger clip body 1 and the finger ring cover 2, and the connecting assembly includes a movable block 4, a fixed block 5 and a connecting rod 6, one end of the connecting rod 6 is rotatably connected to the movable block 4, the other end of the connecting rod 6 is provided with a threaded section 610, and the fixed block 5 is provided with a threaded through hole Ⅰ501 threadedly connected to the threaded section 610. Specifically, the way in which the connecting rod 6 is rotatably connected to the movable block 4 is as follows: combined Figure 4 As shown, a through hole for the connecting rod 6 to pass through is provided on the movable block 4, and two blocking sheets 620 are integrally formed at one end of the connecting rod 6 away from the threaded section 610, and the two blocking sheets 620 are located on both sides of the through hole to prevent the connecting rod 6 from detaching from the movable block 4. The fixed block 5 is fixedly connected to the outer wall of the finger ring sleeve 2, the finger clamp body 1 includes an upper finger clamp plate 110 and a lower finger clamp plate 120, and the movable block 4 is connected to the side walls of the upper finger clamp plate 110 and the lower finger clamp plate 120 through a connecting rope 7. In this embodiment, the number of the fixed block 5, the movable block 4 and the connecting rod 6 are all two, and the two movable blocks 4 are respectively connected to the side walls of the upper finger clamp plate 110 and the lower finger clamp plate 120 through a connecting rope 7 and the two movable blocks 4 are located on the same side, and the fixed block 5 corresponds to the movable block 4 one by one, so that the connecting rod 6 can be threadedly connected with the corresponding threaded through hole Ⅰ501 on the fixed block 5.

[0035] Combination Figure 3As shown, a top sheet 8 is provided inside the finger ring sleeve 2, and the top sheet 8 is arc-shaped; a protrusion 210 is integrally formed on the outer wall of the finger ring sleeve 2, and a threaded through hole II is provided on the protrusion 210, which is connected to the inside of the finger ring sleeve 2, and an adjusting screw 9 is threadedly connected to the threaded through hole II, and one end of the adjusting screw 9 located inside the finger ring sleeve 2 is rotatably connected to the top sheet 8. In this embodiment, the adjusting screw 9 is rotatably connected to the top sheet 8 through a bearing 11. An adjusting cap 10 is integrally formed on one end of the adjusting screw 9 located outside the finger ring sleeve 2, so that the nurse can rotate the adjusting screw 9.

[0036] One end of the wristband 3 is detachably connected to the other end of the wristband 3. Specifically, one end of the wristband 3 is connected to the other end of the wristband 3 by a Velcro or a belt buckle. In this embodiment, one end of the wristband 3 is detachably connected to the other end of the wristband 3 by a Velcro. A tensioning member 12 is provided between the wristband 3 and the finger ring 2. In this embodiment, there are two tensioning members 12, and the tensioning members 12 are selected as inelastic tensioning belts. One tensioning member 12 can be attached to the back of the hand, and the other tensioning member 12 can be attached to the palm. Each tensioning member 12 is sewn with a Velcro male surface (obstructed and not shown) and a Velcro female surface 13. The wristband 3 is fixedly connected with a D-shaped buckle 14. In this embodiment, there are two D-shaped buckles 14. One end of the tensioning member 12 is fixedly connected to the finger ring 2. After the other end of the tensioning member 12 passes through the D-shaped buckle 14, the Velcro male surface on the tensioning member 12 is adhered to the Velcro female surface 13, thereby realizing the connection between the wristband 3 and the finger ring 2.

[0037] When in use, ensure that the connection assembly is disconnected, that is, the connecting rod 6 and the fixing block 5 are in a separated state. Next, first wear the finger ring sleeve 2 on the corresponding finger of the patient, and then clamp the finger clamp body 1 on the fingertip of the corresponding finger of the patient. At this time, the fingertip is located between the upper finger splint 110 and the lower finger splint 120, so as to monitor the blood oxygen saturation. Subsequently, align the two connecting rods 6 with the threaded through holes Ⅰ501 of the corresponding fixing blocks 5 respectively and rotate the connecting rods 6. Since the threaded section 610 is threadedly connected to the threaded through hole Ⅰ501, the connecting rod 6 rotates while pulling the finger ring sleeve 2 to move toward the finger clamp body 1, thereby adjusting the distance between the finger ring sleeve 2 and the finger clamp body 1 to adapt to patients with different finger lengths. When one end of the finger ring sleeve 2 covers the proximal interphalangeal joint toward the finger clamp body 1, the top plate 8 is located above the proximal interphalangeal joint. The nurse no longer rotates the connecting rod 6, but rotates the adjusting screw 9 through the adjusting cap 10. The adjusting screw 9 drives the top plate 8 to move downward until the top plate 8 fits the proximal interphalangeal joint. In this way, the top plate 8 can be used to limit the flexion and extension movement of the proximal interphalangeal joint to prevent the patient's fingers from bending and causing the finger clamp body 1 to fall off.

[0038] Then, the nurse puts the wristband 3 on the patient's wrist, passes the end of the tension piece 12 away from the finger ring 2 through the corresponding D-shaped buckle 14, and adheres the Velcro male surface of the tension piece 12 to the Velcro female surface 13. At this time, one tension piece 12 is attached to the back of the patient's hand, and the other tension piece 12 can be attached to the palm of the patient, so that the tension piece 12 is used to connect the wristband 3 and the finger ring 2, and the effective length of the tension piece 12 is adjustable, which can be applied to hands of different lengths. At this point, the wearing of the blood oxygen saturation finger clip is completed.

[0039] In the above process, when the finger clamp body 1 is clamped on the patient's fingertip, an angle may be formed between the upper finger splint 110 and the lower finger splint 120 (the thicker the finger, the larger the angle), and the connecting rope 7 can adapt to the angle between the upper finger splint 110 and the lower finger splint 120, so that the movable block 4 has a certain range of motion, so that the connecting rod 6 can be horizontally aligned with the threaded through hole Ⅰ501 on the fixed block 5. In addition, after the connecting rod 6 is threadedly connected to the fixed block 5, the connecting rope 7 is tightened to apply tension to the upper finger splint 110 and the lower finger splint 120 to prevent the upper finger splint 110 and the lower finger splint 120 from opening, further ensuring that the finger clamp body 1 will not fall off the fingertip. In addition, the tension applied by the connecting rope 7 to the upper finger splint 110 and the lower finger splint 120 can be adjusted by rotating the connecting rod 6.

[0040] In summary, in this embodiment, the wristband 3 is fixedly worn on the patient's wrist, and the tensioning member 12 is used to effectively prevent the finger ring sleeve 2 from moving toward the fingertip, and the finger ring sleeve 2 applies a pulling force to the finger clamp body 1 through the connecting assembly, effectively preventing the finger clamp body 1 from falling off the patient's fingertip. Moreover, the top sheet 8 in the finger ring sleeve 2 supports the proximal interphalangeal joints of the patient's fingers, preventing the patient's fingers from bending and causing the fingertips to fall off the finger clamp body 1, and the anti-falling effect is good. In addition, in this embodiment, the inner diameter of the finger ring sleeve 2 can be designed to be larger, and the tensioning member 12 and the connecting assembly are both adjustable, so this embodiment can be applied to different patients and has a wide range of applications.

[0041] Embodiment 2

[0042] The difference between this embodiment and the first embodiment is that: Figure 5 and Figure 6 As shown, in this embodiment, a pressure sensor 15 is attached to the bottom surface of the top sheet 8, and a display screen 16 is attached to the tension member 12, and the display screen 16 is used to display the pressure data detected by the pressure sensor 15; wherein the pressure sensor 15 is a patch type pressure sensor 15. In another embodiment, the pressure sensor 15 is arranged on the inner bottom wall of the finger ring sleeve 2.

[0043] In this embodiment, the pressure sensor 15 is used to detect the pressure applied by the top sheet 8 to the patient's proximal interphalangeal joints, and the specific value of the pressure is displayed on the display screen 16 for the convenience of the nurse to check, so as to ensure that the top sheet 8 supports the patient's proximal interphalangeal joints and avoid excessive pressure applied by the top sheet 8 to the patient's proximal interphalangeal joints, thereby causing compression injuries to the proximal interphalangeal joints.
