Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an improved interventional therapy and nursing device. Background Technology

[0002] Interventional therapy nursing care encompasses multiple aspects, including preoperative care, postoperative care, and psychological support. In interventional therapy, bandaging is a crucial postoperative care step, primarily used for compression to stop bleeding, prevent hematoma formation, and protect the puncture site. By applying appropriate pressure to the wound or puncture point, the bandage reduces local blood flow and promotes blood clotting, effectively stopping bleeding. It also provides a physical barrier to the wound, preventing external contamination and bacterial invasion, reducing the risk of infection. Furthermore, it secures dressings, gauze, and medications to the wound, ensuring they remain in place and continue to function, while absorbing wound exudate and keeping the wound dry. During bandaging, it is important to maintain appropriate tightness and observe the local condition.

[0003] Chinese Patent Application Document 1 (Application No.: 2018207782959, Application Date: 2018.05.24) discloses an interventional therapy nursing device, including an inclined frame 1' and a telescopic mechanism 3'. The telescopic mechanism 3' includes an end cap, a storage slot, a blade, a moving rod, a spring, and a bolt. The end cap is installed on the upper side inside the storage slot, the spring is installed at the bottom inside the storage slot, the moving rod is installed on the upper end of the spring, the blade is installed on the upper end of the moving rod, and the bolt is installed on the front side of the annular side of the moving rod. The front end of the bolt extends to the front side of the inclined frame 1', and the rear end of the bolt passes through the moving rod and fits against the rear wall inside the storage slot. The telescopic mechanism 3' of the above solution is cumbersome to adjust, and its operation is far more complex than directly cutting the bandage; moreover, the inclined frame 1' of the above solution is prone to slipping, making the patient's upper limb prone to slipping; and the single-blade design requires a high degree of sharpness during the cutting process, resulting in a heavy maintenance burden.

[0004] Chinese Patent Application Document 2 (Application No.: 2021207355490, Application Date: 2021.04.12) discloses a portable medical tube-type bandage comprising a placement tube and medical gauze. The medical gauze is stored inside the placement tube, and a sealing cap is fitted onto the upper end face of the placement tube. A cutting blade is provided on the outer end face of the placement tube. Through the arrangement of a cutting plate, a first mounting groove, a rotating plate, a squeezing plate, a second mounting groove, and the cutting blade, when the rotating plate is manually turned, the squeezing plate can push the gauze into the second mounting groove. During the pushing process, the gauze can come into frictional contact with the cutting blade, thereby achieving the cutting of the gauze. In the above solution, the placement tube needs to be constantly turned over in hand during use, and the cutting blade is exposed on the outer wall of the placement tube, which can easily scratch the skin of patients and medical staff during use; furthermore, the above solution lacks a bandage fixing device.

[0005] Chinese Patent Application Document 3 (Application No.: 2023227935106, Application Date: October 18, 2023) discloses a bandaging auxiliary device, including a base assembly, a pressing assembly, and a cutting assembly. The base assembly has various groove structures. The pressing assembly is rotatably connected inside the base assembly. The pressing assembly includes a base column, a fixing rod on the front side of the base column, a pressure block on the front side of the fixing rod, and a bracket on the top of the fixing rod. A rotating shaft is rotatably connected inside the bracket. The above solution has a narrow scope of application; it can only be used for cutting and fixing tape when using infusion tubing, and cannot be used for cutting and fixing bandages.

[0006] Therefore, providing an improved interventional therapy and nursing device that is not only easy to operate and adjust, but also able to fix the patient's upper limbs, effectively cut bandages, and is easy to maintain is a technical problem that urgently needs to be solved in this field.

This embodiment provides an improved interventional therapy nursing device, including a base 1, a triangular prism inner pad 2, a fixing component 3, and a cutting component 4, wherein...

[0034] The base 1 includes a quadrilateral base plate 11, a first triangular plate 12, and a second triangular plate 13. The two sides of the base plate 11 along its width direction are integrally connected to the first triangular plate 12 and the second triangular plate 13, respectively. The first triangular plate 12 and the second triangular plate 13 are both right-angled triangular plates. The side projection shape of the base plate 11, the first triangular plate 12, and the second triangular plate 13 along the length direction of the base plate 11 is U-shaped. The first triangular plate 12 has a first concave notch 121 recessed in the right-angle direction of the first triangular plate 12 on the perpendicular line of its inclined surface. The second triangular plate 13 has a second concave notch 131 recessed in the right-angle direction of the second triangular plate 13 on the perpendicular line of its inclined surface. The first concave notch 121 and the second concave notch 131 correspond to each other.

[0035] The triangular prism inner pad 2 is placed between the base plate 11, the first triangular plate 12, and the second triangular plate 13. Its three sides overlap and are bonded to the base plate 11, the first triangular plate 12, and the second triangular plate 13, respectively. The oblique side of the triangular prism inner pad 2 is an arc-shaped surface, and the concave direction of the arc-shaped surface is the same as the concave direction of the first concave notch 121. The cross-sectional shape of the oblique side of the triangular prism inner pad 2 along its length is a second C-shape 201. A rectangular groove 21 is provided on the perpendicular bisector of the arc-shaped surface of the triangular prism inner pad 2, which is connected to the first concave notch 121 and the second concave notch 131. Along the width direction Y of the base plate 11, the orthographic projections of the first concave notch 121, the second concave notch 131, and the rectangular groove 21 overlap with each other.

[0036] The fastener 3 includes a rectangular fastening strap and a rectangular webbing buckle. The webbing buckle is fixedly connected to the side of the second triangular plate 13 away from the first triangular plate 12. One end of the fastening strap is fixedly connected to the side of the first triangular plate 12 away from the second triangular plate 13, and the other end of the fastening strap is movably connected to the webbing buckle. An annular gap for placing the upper limb is formed between the first triangular plate 12, the fastening strap, the second triangular plate 13 and the arc-shaped surface.

[0037] The cutting component 4 includes a fixed guillotine 41 and a movable guillotine 42 connected to the fixed guillotine 41 via a first connecting shaft 45. The fixed guillotine 41 is fixedly connected to the side of the first triangular plate 12 away from the second triangular plate 13. The right-angled triangle of the first triangular plate 12 includes a right-angled short side perpendicular to the base plate 11 and a right-angled long side coinciding with the base plate 11. The movable guillotine 42 rotates within a range of 0 to 90 degrees with the first connecting shaft 45 as a fixed point and the right-angled short side of the first triangular plate 12 in the direction of the right-angled long side of the first triangular plate 12. Along the width direction Y of the base plate 11, the orthographic projection of the first concave notch 121 does not overlap with the orthographic projection of the fixed guillotine 41.

[0038] Specifically, continue to refer to Figure 2 and Figure 3 As shown, the triangular prism inner pad 2 is located inside the base 1, the fixing member 3 is located on two opposite triangular sides of the base 1, and the cutting member 4 is located along one triangular side of the base 1. The base 1 includes a quadrilateral base plate 11 and a first triangular plate 12 and a second triangular plate 13 integrally connected along the length extension direction of both sides of the base plate 11.

[0039] The base plate 11 is a quadrilateral plate with two right angles. One side of the base plate 11 along its length is an isosceles trapezoidal surface. The length of the upper base of the isosceles trapezoidal surface is equal to the shortest distance between the first triangle 12 and the second triangle 13. The length of the lower base of the isosceles trapezoidal surface is equal to the sum of the thicknesses of the first triangle 12 and the second triangle 13 plus the shortest distance between the first triangle 12 and the second triangle 13. The isosceles trapezoidal surface is recessed in the direction of the right-angled short sides of the first triangle 12 and the second triangle 13 to form a first C-shaped shape 111. The isosceles trapezoidal surface that is recessed into the first C-shaped shape 111 can better make the base plate 11 form a smooth end with the triangular prism inner pad 2 at this end, enhancing the comfort of use. The base plate 11 is vertically connected to the first triangular plate 12 and the second triangular plate 13 on both sides along its length extension direction X. The base plate 11, the first triangular plate 12 and the second triangular plate 13 are integrated for support. The base plate 11 is used to provide rigid support for the patient's upper limb, which can be the left forearm or the right forearm. For example, it supports the patient's left forearm. The integrated support base 1 can distribute the compressive force more evenly.

[0040] The first triangle 12 and the second triangle 13 are both right-angled triangles; the long right-angled sides of the first triangle 12 and the second triangle 13 are connected to the two long sides of the base plate 11 of equal length, and the short right-angled sides of the first triangle 12 and the second triangle 13 are perpendicular to the base plate 11. The right-angled ends of the first triangle 12 and the second triangle 13 are both located at the end of the base plate 11 away from its isosceles trapezoidal surface; along the length direction X of the base plate 11, the side view projection shape of the base plate 11, the first triangle 12 and the second triangle 13 is a c-shape, which is used to lock the patient's upper limb.

[0041] The first triangle 12 has a first concave notch 121 recessed in the right-angle direction of the first triangle 12 along the perpendicular bisector of its inclined plane. The first concave notch 121 penetrates the body of the first triangle 12 along the width direction Y of the base plate 11. The second triangle 13 has a second concave notch 131 recessed in the right-angle direction of the second triangle 13 along the perpendicular bisector of its inclined plane. The second concave notch 131 penetrates the body of the second triangle 13 along the width direction Y of the base plate 11. The frontal projections of the rectangular groove 21, the first concave notch 121, and the second concave notch 131 coincide with each other along the width direction Y of the base plate 11. The width of the rectangular groove 21, the first concave notch 121, and the second concave notch 131 along the width direction Y of the base plate 11 is not less than 50 mm. The rectangular groove 21, the first concave notch 121, and the second concave notch 131 are used to allow the bandage roll to pass through the non-inclined surfaces of the first triangle 12 and the second triangle 13 along the width direction Y of the base plate 11.

[0042] Continue to refer to Figures 2-4As shown, the triangular prism inner pad 2 is glued within the space enclosed by the base plate 11, the first triangular plate 12, and the second triangular plate 13. The three sides of the triangular prism inner pad 2 are respectively glued to and overlap with the base plate 11, the first triangular plate 12, and the second triangular plate 13. The cross-section of the triangular prism inner pad 2 perpendicular to its length extension direction is a right-angled triangle; the thickness extension direction of the triangular prism inner pad 2 is the same as the width direction Y of the base plate 11. Along the width direction Y of the base plate 11, the frontal projection of the triangular prism inner pad 2 completely overlaps with the frontal projection of the first triangular plate 12 and the second triangular plate 13; along the length extension direction of the shorter right-angled side of the first triangular plate 12, the top-view projection of the triangular prism inner pad 2 completely overlaps with the frontal projection of the base plate 11. The triangular prism inner pad 2 provides elastic support for the patient's upper body within the base 1, enhancing comfort.

[0043] The oblique side of the triangular prism inner pad 2 away from the base plate 11 is an arc-shaped surface. The concave direction of the arc-shaped surface is the same as the concave direction of the first concave notch 121 or the second concave notch 131. The cross-sectional shape of the triangular prism inner pad 2 along the length of its arc-shaped surface is a second C-shape 201. The opening width of the second C-shape 201 along the width direction Y of the base plate 11 is not less than 150mm. The arc-shaped surface of the second C-shape 201 provides more stable elastic support for the patient's upper limb when it is placed.

[0044] The triangular prism inner pad 2 is provided with a rectangular groove 21 extending through the inner pad 2 along the width Y direction of the base plate 11. The depth of the rectangular groove 21 is the same as the depth of the first concave notch 121 or the second concave notch 131, the width of the rectangular groove 21 is the same as the width of the first concave notch 121 or the second concave notch 131, and the opening direction of the rectangular groove 21 is the same as the opening direction of the first concave notch 121 or the second concave notch 131. The orthographic projections of the first concave notch 121, the second concave notch 131, and the rectangular groove 21 coincide along the width Y direction of the base plate 11. The width of the rectangular groove 21 is not less than 50mm. The rectangular groove 21 is used to allow the bandage roll to pass through the non-sloping surface of the triangular prism inner pad 2 along the width Y direction of the base plate 11. Thus, when the patient's upper limb needs to be bandaged, the bandage roll can pass through the first concave notch 121, the rectangular groove 21, and the second concave notch 131 in sequence, allowing the bandage roll to wrap and bandage the patient's upper limb.

[0045] Continue to refer to Figure 2As shown, the fixing member 3 includes a rectangular fixing strap and a rectangular webbing buckle, which are movably connected. The webbing buckle can be a snap-on webbing buckle, commonly used for belt connections, and is a well-known technology to those skilled in the art. Those skilled in the art can understand the specific structure based on the location and overall structure of this solution, and thus clearly understand how to implement it. The fixing strap is a rectangular strap with one end fixed to the side of the first triangular plate 12 away from the second triangular plate 13. Specifically, the fixing strap is fixed to the side of the first triangular plate 12 near its oblique side. The end of the fixing strap away from the first triangular plate 12 can pass through the webbing buckle and be locked by the tight pressure of the webbing buckle. On the side of the second triangular plate 13 away from the first triangular plate 12, medical personnel can adjust the size of the annular gap formed by the fixing strap, the webbing buckle, the first triangular plate 12, and the second triangular plate 13 to tightly lock the patient's upper limb within the annular gap on the oblique side of the triangular prism inner pad 2.

[0046] Continue to refer to Figure 2 and Figure 5 As shown, the cutting component 4 is fixed to the side of the first triangular plate 12 away from the second triangular plate 13. The cutting component 4 includes a fixed guillotine 41 fixed to the side of the first triangular plate 12 near its right-angled long side, and a movable guillotine 42 fixed to the side of the first triangular plate 12 near its right-angled short side. Along the length direction X of the base plate 11, the end of the fixed guillotine 41 near the right-angled short side of the first triangular plate 12 and the end of the movable guillotine 42 along its length extension direction are connected by a first connecting shaft 45. The length extension direction of the first connecting shaft 45 is perpendicular to the plane of the first triangular plate 12. Through the cooperative use of the fixed guillotine 41 and the movable guillotine 42, a shearing force is generated to cut the bandage.

[0047] The fixed guillotine 41 is rectangular. One wide side of the fixed guillotine 41 is fixed to the side of the first triangular plate 12 near its long right-angle side along the length X of the base plate 11. The length extension direction of the fixed guillotine 41 is parallel to the length extension direction of the long right-angle side of the first triangular plate 12. The blade of the fixed guillotine 41 faces away from the base plate 11. Along the width Y of the base plate 11, the orthographic projection of the first concave notch 121 is located directly above the orthographic projection of the fixed guillotine 41; along the length extension direction of the short right-angle side of the first triangular plate 12, the top view projection of the first concave notch 121 does not coincide with the top view projection of the fixed guillotine 41.

[0048] Along the length X of the base plate 11, the end of the fixed guillotine 41 near the short right-angle side of the first triangular plate 12 is connected to the end of the movable guillotine 42 along its length extension direction via a first connecting shaft 45. The length extension direction of the first connecting shaft 45 is perpendicular to the plane of the first triangular plate 12. The fixed guillotine 41 and the movable guillotine 42 can vary in angle from 0° to 90° via the first connecting shaft 45.

[0049] The movable guillotine 42 is rectangular. One end of the movable guillotine 42 along its length is fixed to the first triangular plate 12 via the first connecting shaft 45. The movable guillotine 42 rotates within a range of 0 to 90 degrees with the first connecting shaft 45 as a fixed point, with the short right-angled side of the first triangular plate 12 pointing towards the long right-angled side of the first triangular plate 12. When the rotation angle of the movable guillotine 42 is 0°, the length extension direction of the movable guillotine 42 is the same as the length extension direction of the short right-angled side of the first triangular plate 12. The blade of the movable guillotine 42 faces the apex of the first triangular plate 12 away from its short right-angled side. The movable guillotine 42 and the fixed guillotine 41 are perpendicular to each other. Along the length direction X of the base plate 11, the side view projection of the first concave notch 121 coincides with the side view projection of the movable guillotine 42. When the rotation angle of the movable guillotine 42 is 90°, the length extension direction of the movable guillotine 42 is the same as that of the fixed guillotine 41, and the blades of the movable guillotine 42 and the fixed guillotine 41 are opposite to each other. During the process of the movable guillotine 42 and the fixed guillotine 41 changing angle from 0° to 90°, the blade of the movable guillotine 42 can sweep across the bandage, thus allowing the movable guillotine 42 and the fixed guillotine 41 to cut the bandage.

[0050] In practical use, the improved interventional therapy and nursing device provided in this embodiment can be used for bandaging the patient's upper limbs; its specific operation is as follows:

[0051] First, place the patient's upper limb on the oblique side of the triangular prism inner pad 2, ensuring that the length extension direction of the upper limb is consistent with the length extension direction of the oblique side of the inner pad. Second, allow the movable end of the fixing strap away from the first triangular plate 12 to pass over the upper limb away from the triangular prism inner pad 2, and further pass through the webbing buckle on the second triangular plate 13. Adjust the movement of the fixing strap, webbing buckle, and triangular prism inner pad 2 to form an annular gap to accommodate the thickness of the patient's upper limb, and then close the webbing buckle to fix the annular gap. Third, fix one end of the bandage on the patient's upper limb, and then allow the bandage roll to pass sequentially through the second concave notch 131, the rectangular groove 21, and the first concave notch 121, wrapping it around the patient's upper limb once. Fourth, repeat the third step multiple times to complete the bandaging, allowing the bandage roll to extend past the fixed guillotine 41 in a direction away from the first triangular plate 12; then, with the other hand, press down on the end of the movable guillotine 42 away from the fixed guillotine 41, and push the movable guillotine 42 with the short right-angle side of the first triangular plate 12 towards the long right-angle side of the first triangular plate 12, pressing down to cut.

[0052] Compared with the prior art, the improved interventional therapy and nursing device provided in this embodiment achieves at least the following beneficial effects:

[0053] First, the improved interventional therapy nursing device provided in this embodiment makes the operation of cutting bandages simple and easy to use. First, the movable guillotine 42 provided in this embodiment does not require additional adjustment; it can be cut simply by pressing lightly. There is no need to store the movable guillotine 42 or fix and adjust the fixed guillotine 41. Furthermore, the fixing strap and webbing buckle provided in this embodiment are easy to connect and can quickly fix the patient's upper limb within 3 seconds, requiring only one threading operation.

[0054] Secondly, the improved interventional treatment and nursing device provided in this embodiment can fix the patient's upper limb and avoid secondary injury. First, the triangular prism inner pad 2 provided in this embodiment can provide flexible support for the patient's upper limb. In addition, the triangular prism inner pad 2 has an arc-shaped surface, which can lock the patient's upper limb. Furthermore, this embodiment also provides a fixing strap and a webbing buckle, which can also bind and fix the patient's upper limb, thereby facilitating the fixation of the patient's upper limb and preventing it from falling off during the bandaging process.

[0055] Third, the improved interventional treatment nursing device provided in this embodiment has a good bandage cutting effect and is easy to maintain. First, the movable guillotine 42 and the fixed guillotine 41 provided in this embodiment have an angle change of 0~90°, thereby cutting the bandage. The cutting effect is better than that of a single-edged blade. Furthermore, the movable guillotine 42 and the fixed guillotine 41 provided in this embodiment do not require additional adjustment. The triangular prism inner pad 2 and the base 1 are fixedly connected. The overall structure is simple, easy to use, and easy to maintain.

[0061] With the above design, the width of the movable blade 422 is smaller than the width of the movable blade holder 421. This design ensures that the movable blade 422 has sufficient space inside the movable blade holder 421, thus preventing the blade from being exposed. This allows the movable blade 422 to be completely hidden inside the movable blade holder 421. This design effectively prevents the movable blade 422 from being exposed during the cutting of bandages, thereby preventing medical personnel from being cut during the operation.

[0062] In one alternative embodiment, continue to refer to Figure 2 , Figure 6 and Figure 7 As shown, Figure 6 yes Figure 5 Enlarged view of point A in the middle; Figure 7 The present invention provides a schematic diagram of the structure of the movable blade; the movable blade holder 421 has a movable through hole 423 communicating with the movable rectangular slot at one end away from the first connecting shaft 45; the movable blade 422 includes a rectangular movable blade strip 4221, a rectangular block-shaped movable block 4222, and a movable spring 4223.

[0063] One end of the movable blade 4221 is fixedly connected to the two side groove walls of the movable blade holder 421 near the end of the first connecting shaft 45 via the second connecting shaft 44. The other end of the movable blade 4221 is engaged with a movable block 4222. The movable block 4222 passes through the movable through hole 423 and reciprocates along the width direction of the movable blade holder 421. A movable spring 4223 is connected between the end of the movable block 4222 away from the movable rectangular groove and the side of the movable blade holder 421 away from the first connecting shaft 45. Along the width direction of the base plate 11, the orthographic projection of the second connecting shaft 44 and the orthographic projection of the first connecting shaft 45 do not overlap at all.

[0064] Along the width direction of the movable tool holder 421, the width of the movable blade 4221 is less than the depth of the movable rectangular groove; along the length direction of the movable tool holder 421, the length of the movable blade 4221 is less than the length of the movable rectangular groove, and the sum of the lengths between the movable blade 4221 and the movable block 4222 is greater than the length of the movable tool holder 421.

[0065] Specifically, a movable through hole 423 is provided on the side of the movable tool holder 421 away from the fixed tool holder 411. The movable through hole 423 is a rectangular through hole that penetrates the movable tool holder 421. The length and width of the movable through hole 423 are both smaller than the length and width of the side of the movable tool holder 421 away from the fixed tool holder 411. The geometric center of the movable through hole 423 coincides with the geometric center of the side of the movable tool holder 421 away from the fixed tool holder 411. A movable tool bar 4221 is provided at the bottom of the groove of the movable tool holder 421, extending along its length and protruding through the movable through hole 423.

[0066] One end of the movable blade 4221 is fixed to the two side groove walls of the movable blade holder 421 near the fixed blade holder 411 via the second connecting shaft 44. The other end of the movable blade 4221 extending along its length is engaged with a movable block 4222. The movable block 4222 passes through the side of the movable blade holder 421 away from the second connecting shaft 44. The side of the movable block 4222 away from the movable rectangular groove and the bottom of the groove away from the first connecting shaft 45 are respectively connected to the head and tail ends of the movable spring 4223.

[0067] The width of the movable blade 4221 along the width direction Y of the base plate 11 is less than the depth of the movable rectangular groove, the length of the movable blade 4221 is less than the length of the movable rectangular groove, and the sum of the lengths of the movable blade 4221 and the movable block 4222 is greater than the length of the movable rectangular groove. One end of the movable blade 4221 along its length is fixed to both sides of the movable rectangular groove via a second connecting shaft 44, specifically at the end of the movable rectangular groove closest to the first connecting shaft 45. The length extension direction of the second connecting shaft 44 is perpendicular to the plane of the first triangular plate 12, and one end of the second connecting shaft 44 along its length is glued to the plane of the first triangular plate 12 on the side away from the second triangular plate 13. The movable blade 4221 forms an angle of 0~30° with the movable blade holder 421 on the second connecting shaft 44. When the angle between the movable blade 4221 and the movable blade holder 421 is 0°, the blade of the movable blade 4221 is completely hidden in the movable blade holder 421; when the angle between the movable blade holder 421 and the movable blade 4221 is 30°, the blade of the movable blade 4221 is exposed from the opening of the movable rectangular groove.

[0068] A movable block 4222 is engaged with the back of the movable blade 4221 at the end away from the second connecting shaft 44. The movable block 4222 passes through the movable through hole 423 on the side of the movable blade holder 421 away from the second connecting shaft 44. The width of the movable blade 4221 is less than the depth of the movable rectangular groove, the length of the movable blade 4221 is less than the length of the movable rectangular groove, and the sum of the lengths of the movable blade 4221 and the movable block 4222 is greater than the length of the movable blade holder 421. The movable block 4222 is a rectangular block with the same width as the movable through hole 423 and a length less than 1 / 3 of the length of the movable through hole 423. The movable block 4222 can slide within the movable through hole 423 along its length extension direction. The side of the movable block 4222 away from the movable rectangular groove and the bottom of the movable rectangular groove away from the first connecting shaft 45 are respectively connected to the head and tail ends of the movable spring 4223. The movable block 4222 can push the movable blade 4221 to change the angle between the movable blade holder 421 and the second connecting shaft 44 at 0~30°.

[0069] The movable spring 4223 is a metal spring wire. When the movable spring 4223 is in its natural state, the movable block 4222 is located at the end of the movable through hole 423 away from the opening of the movable rectangular groove, the width of the movable blade 4221 is less than the depth of the movable rectangular groove, and the blade of the movable blade 4221 is housed in the movable rectangular groove.

[0070] In practical use, when the movable block 4222 is pushed along the length of the movable through hole 423, the movable block 4222 moves from the end of the movable through hole 423 away from the movable rectangular groove to the end closer to the movable rectangular groove. At this time, the blade of the movable blade 4221 extends out from the opening of the movable rectangular groove. When the movable blade holder 421 and the fixed blade holder 411 are fully engaged (with an included angle of 0°), the blade of the movable blade 4221 can further extend into the fixed rectangular groove, where it cuts with the fixed blade. After the cutting is finished, the movable block 4222 is released, and under the contraction force of the movable spring 4223, the movable block 4222 automatically returns to the end of the movable through hole 423 away from the movable rectangular groove, and the movable blade 4221 is once again stored and hidden in the movable rectangular groove.

[0071] With the above solution, the movable spring 4223 can retract and hide the movable blade 4221 after use; at the same time, a movable block 4222 and a second connecting shaft 44 are provided to fix the movable blade 4221. By gently pushing the movable block 4222, the movable blade 4221 can be inserted into the fixed blade holder 411 to perform a hidden cutting.

[0072] In one alternative embodiment, continue to refer to Figure 2 As shown, a return spring 43 is provided on the side of the movable tool holder 421 away from its slot and on the end away from the first connecting shaft 45. One end of the return spring 43 is fixedly connected to the movable tool holder 421, and the other end of the return spring 43 is glued to the side of the first triangular plate 12 away from the second triangular plate 13.

[0073] Specifically, the return spring 43 is a metal spring wire. One side of the return spring 43 along its length extension direction contacts the side of the first triangular plate 12 away from the second triangular plate 13. One end of the return spring 43 is glued and fixed to the side of the first triangular plate 12 away from the second triangular plate 13. The other end of the side of the first triangular plate 12 away from the second triangular plate 13 is glued and fixed to the end of the movable tool holder 421 away from the first connecting shaft 45. Specifically, it is fixed to the side of the movable tool holder 421 away from the movable rectangular slot.

[0074] When the return spring 43 is in its natural extension and contraction state, the length extension direction of the return spring 43 is the same as the length direction X of the rectangular base plate 11, and the angle between the movable blade holder 421 and the fixed blade holder 411 is 90° in the open state; when the movable block 4222 is loosened and the shearing is finished, the movable blade holder 421 is affected by the contraction force of the return spring 43 and automatically returns to the open state with a 90° angle with the fixed blade holder 411.

[0075] With the above solution, after the medical staff completes the cutting, the movable blade holder 421 automatically returns to the open state at a 90° angle with the fixed blade holder 411, so that the fixed blade 41 and the movable blade 42 can be used immediately for secondary cutting, which is convenient for the medical staff to use next time and saves manpower.

[0076] In one alternative embodiment, continue to refer to Figures 2-4 As shown, the triangular prism inner pad 2 includes a triangular prism support block 22, a first trapezoidal block 23, and a second trapezoidal block 24, which are placed between the base plate 11, the first triangular plate 12, and the second triangular plate 13.

[0077] The upper bottom surface of the first trapezoidal block 23 and the upper bottom surface of the second trapezoidal block 24 are fixedly bonded to the oblique side surface of the triangular prism support block 22, respectively. The first trapezoidal block 23 and the second trapezoidal block 24 are located on both sides of the rectangular groove 21 along the length extension direction of the oblique side surface of the triangular prism support block 22.

[0078] The first trapezoidal block 23 and the second trapezoidal block 24 are both right-angled trapezoids with an upper base smaller than the lower base. The lower base of the first trapezoidal block 23 and the second trapezoidal block 24 are both arc-shaped surfaces that are concave towards their upper base.

[0079] Specifically, the triangular prism support block 22 can be made of polyethylene or polyurethane with a Shore hardness greater than 50. Both polyethylene and polyurethane are inexpensive and readily available. The triangular prism support block 22 is a triangular prism with a right-angled triangle cross-section. The length of the triangular prism support block 22 extends in the width direction Y of the base plate 11. Along the width direction Y of the base plate 11, the frontal projection of the triangular prism support block 22 coincides with the frontal projection of the first triangular plate 12. The triangular prism support block 22 is used to provide good rigid support for the first trapezoidal block 23 and the second trapezoidal block 24.

[0080] The upper base surfaces of the first trapezoidal block 23 and the second trapezoidal block 24 are respectively disposed on the oblique side surface of the triangular prism support block 22. The thickness of the first trapezoidal block 23 and the second trapezoidal block 24 is equal to the length of the triangular prism support block 22. The sum of the lengths of the upper base surfaces of the first trapezoidal block 23 and the second trapezoidal block 24 is less than the length of the oblique side surface of the triangular prism support block 22, thereby allowing the triangular prism support block 22, the first trapezoidal block 23 and the second trapezoidal block 24 to completely fill the space between the base plate 11, the first triangular plate 12 and the second triangular plate 13. The oblique side surfaces of the first trapezoidal block 23 and the second trapezoidal block 24 are far apart from each other. The side of the first trapezoidal block 23 near the second trapezoidal block 24, the side of the second trapezoidal block 24 near the first trapezoidal block 23 and part of the oblique side surface of the triangular prism support block 22 are arranged to form a rectangular groove 21. The lower base of the first trapezoidal block 23 and the lower base of the second trapezoidal block 24 are both arc-shaped surfaces that are concave towards their upper base surfaces. These arc-shaped surfaces are used to support the patient's upper limbs, so that the patient's upper limbs can be engaged along the length of the oblique side of the triangular prism support block 22.

[0081] Through the above scheme, the triangular prism support block 22 enables the triangular prism inner pad 2 to have a stronger ability to support the patient; through the rectangular groove 21, medical staff can pass through the rectangular groove 21 along the width direction Y of the base plate 11 during the bandage application process, and the movable guillotine 42 can cut the bandage, thus achieving rapid fixation of the bandage.

[0082] In one alternative embodiment, continue to refer to Figure 2 and Figure 4 As shown, a T-shaped column 25 is provided on the oblique side of the triangular prism support block 22 corresponding to one side of the rectangular groove 21. The T-shaped column 25 includes a horizontal section and a vertical section that is perpendicularly connected to the middle of the horizontal section. The vertical section is fixedly connected to the oblique side of the triangular prism support block 22.

[0083] Specifically, a T-shaped post 25 is fixedly installed on the inclined side of the triangular prism support block 22 corresponding to the rectangular groove 21. The T-shaped post 25 includes a horizontal section and a vertical section perpendicular to the middle of the horizontal section. The horizontal section is a round rod made of rubber, and its length is no more than half the width of the groove in the rectangular groove 21. The vertical section can be a round rod of the same material as the triangular prism support block 22. The end of the vertical section away from the horizontal section is fixed to the inclined side of the triangular prism support block 22 inside the rectangular groove 21. The triangular prism support block provides stable support for the T-shaped post 25. The T-shaped post 25 is used to hold the tape.

[0084] Through the above scheme, medical tape can be installed on the T-shaped column 25 in this embodiment; the inner ring of the medical tape can overcome the elastic resistance of the horizontal section, engage with the outer wall of the vertical section, and rotate freely on the outer wall of the vertical section, so that after the medical staff completes the bandaging, they can pull the end of the medical tape from the second triangular plate 13 to the first triangular plate 12, and cut the medical tape with the movable guillotine 42 to achieve rapid fixation of the bandage.

[0085] In one alternative embodiment, continue to refer to Figure 2 As shown, a circular groove 221 is provided on the oblique side of the triangular prism support block 22 corresponding to the rectangular groove 21. The circular groove 221 is recessed towards the bottom plate 11. Along the depth direction of the first concave notch 121, the depth of the circular groove 221 is not less than the length of the vertical segment, and the diameter of the circular groove 221 is equal to the outer diameter of the vertical segment. An internal thread is provided on the inner wall of the circular groove 221, and an external thread matching the internal thread is provided on the outer wall of the vertical segment. The vertical segment and the oblique side of the triangular prism support block 22 are connected by the internal thread and the external thread.

[0086] Specifically, a circular groove 221 is provided through the oblique side of the triangular prism support block 22. The opening of the circular groove 221 is circular, and its opening direction is the same as that of the rectangular groove 21. The diameter of the circular groove 221 is equal to the outer diameter of the vertical segment and is fitted with the vertical segment. The depth of the circular groove 221 is not less than the length of the vertical segment and not greater than the height of the triangular side of the triangular prism support block 22. An internal thread is provided on the inner wall of the circular groove 221, and the internal thread extends spirally along the length extension direction of the circular groove 221. An external thread that fits the internal thread is provided on the outer wall of the vertical segment, and the external thread extends spirally along the length extension direction of the vertical segment.

[0087] The above solution enables the triangular prism support block 22 to be fixedly connected to the T-shaped column 25, while allowing the T-shaped column 25 to be retracted and stored towards the triangular prism support block 22 through the circular groove 221. When medical tape is not used, or when the medical tape used is a cut-free medical tape, the T-shaped column 25 can be spirally stored.

[0088] In one alternative embodiment, continue to refer to Figure 2 and Figure 5 As shown, along the width direction of the fixed tool holder 411, the width of the fixed blade is less than the depth of the fixed rectangular groove; along the length direction of the fixed tool holder 411, the length of the fixed blade is less than the length of the fixed rectangular groove.

[0089] Specifically, the width of the fixed blade along the thickness direction of the base plate 11 is less than the depth of the fixed rectangular groove of the fixed blade holder 411, to prevent the excessively wide fixed blade from extending beyond the opening of the fixed rectangular groove, thereby avoiding cuts to medical personnel during use. The length of the fixed blade along the length direction of the base plate 11 is less than the length of the fixed rectangular groove of the fixed blade holder 411, so that the back of the fixed blade can be fixed to the bottom of the groove of the fixed blade holder 411 along its length extension direction.

[0090] The above solution can further prevent the movable guillotine 42 from scratching medical staff during the bandage cutting process. This embodiment provides a fixed blade with a width smaller than the fixed blade holder 411, which can effectively hide the fixed blade and avoid scratches from one side of the fixed blade holder 411.
