Description

Technical Field

[0001] The present invention relates to the technical field of medical nursing equipment, and in particular to a nursing equipment for preventing skin pressure injury of patients after interventional surgery. Background Art

[0002] Cervical spine surgery is a series of surgical treatments for cervical spine diseases. The main purpose of cervical spine surgery is to relieve the compression of cervical nerves, spinal cord and blood vessels caused by cervical spine degeneration, injury or other pathological conditions, relieve pain, improve nerve function, and restore the stability and normal physiological curvature of the cervical spine. After cervical spine surgery, in order to limit the movement of the patient's neck and facilitate the healing of the wound, the patient is usually required to wear a neck brace to provide neck care.

[0003] The cervical collar used in cervical spine surgery is generally a hard cervical collar, which has good supporting and protective effects. However, during its use, it needs to come into contact with the body around the patient's neck in order to support the neck. Since it itself needs to be made of hard materials to ensure the supporting effect, it will produce a certain amount of pressure on the supporting area near the patient's neck, which will then cause pressure damage to the skin of the neck. In the prior art, a pad can be provided at the contact position between the cervical collar and the skin to prevent skin pressure damage, and at the same time, it can also improve the comfort of the cervical collar after wearing it. However, after the patient wears the cervical collar, the neck area inevitably needs to perform certain activities. During the activities, the chin part frequently rubs and contacts with the pad at the corresponding position, which makes it easy for the pad to be stained with sweat stains and is difficult to disassemble and clean. After the cervical collar has been worn for a period of time, it will become loose due to the patient's activities and needs to be put on again to ensure the nursing effect of the cervical collar. The operation is relatively cumbersome. Therefore, the present application provides a nursing device for preventing pressure damage to the skin of patients after interventional surgery to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a nursing device for preventing skin pressure injuries of patients after interventional surgery to solve the problems that the pad on the existing neck collar is inconvenient to disassemble and clean, the position of the pad cannot be adjusted, and the operation of re-wearing it after it becomes loose is cumbersome.

[0014] Optionally, the elastic component includes a through-hole opened on the fixed seat corresponding to the positions of the guide rod and the threaded rod, and a first connecting plate is sleeved in the through-hole. The first connecting plate is fixedly connected to the guide rod and the threaded rod, and both ends of the first connecting plate are connected and fixed to the through-hole through connecting ends.

[0015] Optionally, two symmetrically distributed first weakening grooves are provided on the first connecting plate, the first weakening grooves are C-shaped, and the first weakening grooves are bent in a direction away from the fixing seat, and the width of the first connecting plate is smaller than the width of the through-opening.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by providing a back neck pad and side protection pads as well as a chest support area and a chin protection pad, the areas where the first neck support piece and the second neck support piece contact the patient's skin after being worn are protected to avoid pressure injuries and improve the comfort of the patient after wearing the device. Different support states are provided for the patient's chin area through the first support area and the second support area on the chin protection pad to adapt to different usage conditions and ensure the adaptability range of the equipment.

[0018] By providing an adjustment component, when the first neck support piece and the second neck support piece become loose during wearing, the position of the chin protection pad can be adjusted quickly and conveniently through the adjustment component, thereby regaining the supporting effect of the first neck support piece and the second neck support piece on the patient's neck area. At the same time, the existence of the adjustment component enables the chin protection pad to be displaced and adjusted on the inner side of the annular protection zone, and changed according to the body shape of different users, thereby further improving the adaptability range of the equipment.

[0019] By setting up the installation component, the assembly and disassembly operations between the chin protection pad and the fixing seat are simple and convenient. After installation, it has strong stability and is convenient for support and protection during work. When disassembling, the installation component and the adjustment component can be matched with each other. After the adjustment component is adjusted to a specific position, the chin protection pad and the fixing seat can be automatically disassembled and separated, and the structure between the installation component and the adjustment component is matched, thereby making the correlation between the various structures in the whole scheme stronger and more ingenious.

[0020] By providing an elastic component, the position of the chin guard and the fixing seat can be adjusted by displacement through the adjustment component. The squeezing of the chin guard by the patient's activities can also drive the chin guard and the fixing seat to move under the action of the elastic component. On the one hand, it can further cooperate with the adjustment component to expand the adjustable range of the chin guard, and then expand the adaptation range of the equipment. On the other hand, it can also make the chin guard easier to adapt to the patient's activities, further improving the comfort of the patient after wearing the equipment.

[0021] By providing the first weakened groove and the through-hole in the elastic component, a certain gap is created between the first connecting plate and the fixed seat through the through-hole, thereby reducing the connection points between the first connecting plate and the fixed seat, allowing the first connecting plate to be deformed at the first weakened groove so that the fixed seat and the chin protection pad can be offset from the guide rod and the threaded rod. The C-shaped structure of the first weakened groove that bends toward the outside of the fixed seat can avoid interference from the internal structure of the fixed seat during the deformation of the first connecting plate, thereby making the entire elastic component work more smoothly.

[0044] like Figures 1 to 13As shown, an embodiment of the present invention provides a nursing device for preventing skin pressure injuries of patients after interventional surgery, including a first neck brace 1 and a second neck brace 2. A fixing frame 8 is fixedly connected to the middle part of the first neck brace 1, and the fixing frame 8 and the second neck brace 2 are connected and fixed by Velcro. The first neck brace 1 and the second neck brace 2 are both arc-shaped plate structures that match the shape of the patient's neck area. The fixing frame 8 on the first neck brace 1 is used to connect the two ends of the Velcro, so that the first neck brace 1 and the second neck brace 2 can remain stable after being connected and fixed by Velcro, and the postoperative wound area of ​​the patient is wrapped and protected to avoid tearing of the wound due to pulling on the wound due to excessive movement of the patient's head. The Velcro connection method enables the internal space formed by the combination of the first neck brace 1 and the second neck brace 2 to be adjusted through the connection position of the Velcro to adapt to patients of different body shapes.

[0045] The inner side of the second neck support piece 2 is provided with a back neck pad 3 and a side protection pad 4, the top area of ​​the first neck support piece 1 is provided with an annular protection area 6, and the bottom area of ​​the first neck support piece 1 is provided with a chest support area 7, the annular protection area 6 is provided with a chin protection pad 11 and a fixing seat 14, and the chest support area 7 is provided with a chest pad 5. When the neck support formed by the first neck support piece 1 and the second neck support piece 2 protects the patient's neck, the main contact positions with the patient's body are the back neck, both sides of the neck, the chest support area and the chin area during the patient's activities. Therefore, a back neck pad 3 corresponding to the back neck, side protection pads 4 corresponding to both sides of the neck, a chest pad 5 corresponding to the chest support area and a chin protection pad 11 corresponding to the chin area are provided to protect the skin in these areas and avoid pressure injuries to the skin.

[0046] The adjusting component is used to adjust the relative position between the fixing seat 14 and the annular protection zone 6, and the adjusting component is connected to the annular protection zone 6; the installing component is used to install and fix the chin protection pad 11 and the fixing seat 14, and the installing component is connected to the fixing seat 14; the elastic component is used for the adaptive displacement of the chin protection pad 11 when the patient's activities affect the chin protection pad 11, and the elastic component is connected to the fixing seat 14. The position of the chin protection pad 11 can be adjusted by the adjusting component. When the first neck support sheet 1 and the second neck support sheet 2 are loosened after wearing, the position of the chin protection pad 11 is adjusted to generate pressure against the patient's chin, so as to maintain the first neck support sheet 1 and the second neck support sheet 2. The neck brace 1 and the second neck brace 2 are stable to wear, and the chin protection pad 11 is connected and fixed to the fixing seat 14 by the installation component, and can also be quickly disassembled and replaced through the structure of the installation component, and cooperate with the adjustment component. The chin protection pad 11 is automatically disassembled after the position of the chin protection pad 11 is adjusted to a certain degree by the adjustment component. The elastic component can allow the fixing seat 14 and the chin protection pad 11 to be offset as a whole when the patient's head moves, adapt to the patient's activities, improve the patient's comfort after wearing the device, and avoid excessive squeezing of the patient's chin during the use of the adjustment component to cause discomfort to the patient.

[0047] In this embodiment, if Figures 1 to 3As shown, there are two groups of side protection pads 4 in the second neck support piece 2, and the two groups of side protection pads 4 are symmetrically distributed on the inner wall of the second neck support piece 2. The back neck pad 3 in the second neck support piece 2 is located in the middle area of ​​the two groups of side protection pads 4. The chin protection pad 11 is provided with a first support area 12 and a second support area 13. The first support area 12 is close to the edge of the annular protection area 6, and the thickness of the first support area 12 is greater than the thickness of the chin protection pad 11. The setting of the first support area 12 and the second support area 13 divides the chin protection pad 11 into two areas, one part is the light extrusion limiting area of ​​the first support area 12, and the other part is the enhanced extrusion limiting area of ​​the second support area 13. During normal use, the support effect can be achieved by only relying on the first support area 12 to contact the patient's chin. When the deformation of the first support area 12 is not enough to meet the patient's wearing needs, the chin protection pad 11 is deformed again and contacts the patient's chin area The second support area 13 and the back neck pad 3 are in contact with each other for support and protection, the second support area 13 and the outer part of the back neck pad 3 are both wavy, the first neck support piece 1 is provided with a through opening corresponding to the position of the fixing frame 8, and the first neck support piece 1 is symmetrically provided with lightweight openings evenly distributed on both sides of the through opening, and the first neck support piece 1 and the second neck support piece 2 are provided with ventilation holes, and the wavy structure of the second support area 13 and the back neck pad 3 can leave a certain gap between the second support area 13 and the back neck pad 3 and the patient's skin after being attached, and then cooperate with the ventilation holes on the first neck support piece 1 and the second neck support piece 2 to facilitate air circulation and improve the comfort of the patient after wearing the equipment, and the through opening and lightweight opening on the first neck support piece 1 can also reduce the weight of the first neck support piece 1 without affecting the overall structural strength of the first neck support piece 1, reduce the burden on the patient after wearing it, and reduce the raw materials required in the production process, thereby reducing the production cost.

[0048] In this embodiment, if Figures 2 to 7As shown, the adjustment component includes a threaded sleeve 16 movably connected between the bearing and the annular protection zone 6, one end of the threaded sleeve 16 extends to the outside of the annular protection zone 6 and is fixedly connected to the knob 9, and the other end of the threaded sleeve 16 extends to the inside of the annular protection zone 6 and is threadedly connected to a threaded rod 21, one end of the threaded rod 21 away from the threaded sleeve 16 is connected to the fixed seat 14, and guide tubes 10 located on both sides of the threaded sleeve 16 are symmetrically installed on the annular protection zone 6, and a guide rod 20 is slidably sleeved in the guide tube 10, and one end of the guide rod 20 away from the guide tube 10 is connected to the fixed seat 14, and the guide tube 10 and the threaded sleeve 16 are parallel to each other. The parallel position relationship between the guide tube 10 and the threaded sleeve 16 can make the adjustment direction of the entire adjustment component along the guidance of the guide tube 10 and the guide rod 20, so as to ensure the adjustment direction of the adjustment component, and a limiting disc is provided at one end of the guide rod 20 located in the guide tube 10, and a guide rod 20 is provided in the guide tube 10 to be connected to the guide rod 20 and The shape of the limiting disc is adapted to the slideway to avoid excessive adjustment that may cause the guide tube 10 to separate from the guide rod 20. The bearing between the threaded sleeve 16 and the annular protection zone 6 can ensure the rotation ability of the annular protection zone 6. When the first cervical support plate 1 and the second cervical support plate 2 become loose due to the patient's activities, the first cervical support plate 1 maintains the supporting contact effect between the chest support area 7 and the chest pad 5 and the patient's chest area under the action of its own gravity, while the chin protection pad 11 that can originally squeeze and support the patient's chin area is away from the patient's chin area and cannot provide a good supporting effect. At this time, rotating the knob 9 can drive the threaded sleeve 16 to rotate, and then through the thread between the threaded sleeve 16 and the threaded rod 21, the fixing seat 14 is pushed to slide along the guide of the guide tube 10 and the guide rod 20 as a whole, and then the position of the chin protection pad 11 on the inner side of the annular protection zone 6 is adjusted, and the chin protection pad 11 is pressed against the patient's chin area to maintain the supporting effect of the first cervical support plate 1 and the second cervical support plate 2 on the neck.

[0049] In this embodiment, if Figures 7 to 12As shown, the mounting assembly includes a connecting seat 25 fixedly connected to the outside of the chin protection pad 11, a groove matching the shape of the connecting seat 25 is opened in the fixing seat 14, an inclined surface 26 is opened at the end of the connecting seat 25 away from the chin protection pad 11, and the connecting seat 25 is opened with evenly distributed lightweight openings, the chin protection pad 11 and the fixing seat 14 are connected through the connecting seat 25, the connecting seat 25 and the fixing seat 14 are both made of hard plastic, which can ensure the stability of the chin protection pad 11 after connection and fixation, the groove in the fixing seat 14 can adapt to the overall shape of the connecting seat 25, and facilitate the docking between the connecting seat 25 and the fixing seat 14, the setting of the inclined surface 26 on the connecting seat 25 can reduce the area of ​​the connecting seat 25 in this area, thereby facilitating the plug-in assembly of the connecting seat 25 to the groove area in the fixing seat 14, and the lightweight opening opened on the connecting seat 25 can reduce the weight of the connecting seat 25 without affecting the overall structural strength of the connecting seat 25, and reduce the material cost required for the production of the connecting seat 25.

[0050] In this embodiment, if Figures 7 to 12 As shown, two second connecting plates 27 are symmetrically installed on one side of the extrusion plate 15 away from the chin protection pad 11, and a clamping joint 22 is fixedly connected to the end of the second connecting plate 27, and a second weakened groove 28 is provided on the second connecting plate 27. The second weakened groove 28 makes the thickness of the second connecting plate 27 at the second weakened groove 28 thinner and weaker, so that the second connecting plate 27 can be deformed at the second weakened groove 28 after being subjected to an external force, and a clamping interface 24 corresponding to the position of the clamping joint 22 and matched in size is provided on the fixing seat 14, and a connecting seat 25 corresponding to the position of the second connecting plate 27 is fixedly connected to the inner side wall of the annular protection zone 6, and a first extrusion surface 17 is provided at the end of the extrusion plate 15. A second extrusion surface 23 that is adapted to the shape of the first extrusion surface 17 is provided on the outer side of the head 22. When the chin protection pad 11 and the fixing seat 14 are installed and fixed, the connecting seat 25 on the chin protection pad 11 is directly inserted into the fixing seat 14, and the connecting seat 25 enters the fixing seat 14. During this process, the card joint 22 will contact and be squeezed with the inner wall of the card interface 24, and then the second connecting plate 27 will be deformed at the second weakened groove 28. After the connecting seat 25 and the fixing seat 14 are fully docked, the card joint 22 completely passes through the card interface 24. At this time, the second connecting plate 27 recovers its deformation under the action of its own elastic force, so that the card interface 24 is clamped on the outside of the fixing seat 14, thereby realizing the connection and fixation between the fixing seat 14 and the connecting seat 25.

[0051] When the chin protection pad 11 needs to be disassembled and cleaned, the knob 9 is rotated so that the fixing seat 14 drives the chin protection pad 11 to approach the inner wall of the annular protection zone 6 until the clamping joint 22 and the extrusion plate 15 contact each other, and then the knob 9 is continuously rotated so that the first extrusion surface 17 on the extrusion plate 15 fits with the second extrusion surface 23 on the clamping joint 22, and the second extrusion surface 23 is extruded. After the second extrusion surface 23 is extruded, the second connecting plate 27 is bent and deformed at the second weakened groove 28, so that the second extrusion surface 23 is compressed. The pressing surface 23 avoids the extrusion plate 15, ending the clamping relationship between the clamping joint 22 and the clamping interface 24, releasing the connection and fixation between the connecting seat 25 and the fixing seat 14, and then separating the fixing seat 14 from the connecting seat 25 by the elastic force generated when the second connecting plate 27 recovers its deformation, completing the disassembly of the chin protection pad 11, relying on the adjustment of the adjustment component to achieve linkage with the installation component, so that the adjustment component and the installation component are matched, thereby making the disassembly and separation operation of the chin protection pad 11 and the fixing seat 14 simple and convenient.

[0052] In this embodiment, if Figure 7 and Fig.12 Figure and Fig.13As shown, the elastic component includes a through hole 30 opened on the fixing seat 14 and corresponding to the position of the guide rod 20 and the threaded rod 21, and a first connecting plate 18 is sleeved in the through hole 30. The first connecting plate 18 is fixedly connected to the guide rod 20 and the threaded rod 21, and the two ends of the first connecting plate 18 are connected and fixed to the through hole 30 through the connecting ends 29. Two symmetrically distributed first weakening grooves 19 are provided on the first connecting plate 18. The opening of the first weakening groove 19 makes the thickness of the first connecting plate 18 at this location thinner and the strength weaker, so that the first connecting plate 18 can be deformed at the first weakening groove 19 after being subjected to external force. The first weakening groove 19 is C-shaped, and the first weakening groove 19 is bent in the direction away from the fixing seat 14. The shape and position of the first weakening groove 19 ensure that the first connecting plate 18 will not be deformed with the structure on the inner side of the fixing seat 14 when it is deformed at the first weakening groove 19. Interference is generated between them, the width value of the first connecting plate 18 is smaller than the width value of the through-hole 30, and the width value of the first connecting plate 18 is smaller than the width value of the through-hole 30, so that there is a certain gap between the first connecting plate 18 and the through-hole 30, which is easy for the first connecting plate 18 to be deformed after being acted upon by external force, and the offset movement between the fixing seat 14 and the first connecting plate 18. When the head is moved after wearing the first cervical support plate 1 and the second cervical support plate 2, the chin protection pad 11 will be subjected to pressure from the patient's chin area and adapt to the patient's movements through its own deformation. At the same time, the first connecting plate 18 will also undergo adaptive deformation at the first weakened groove 19, so that a certain inclination is generated between the first connecting plate 18 and the guide rod 20 and the threaded sleeve 16, and then the fixing seat 14 together with the chin protection pad 11 will be tilted as a whole to adapt to the patient's movements, thereby further improving the comfort of the patient's activities after wearing the equipment.

[0053] The working principle of the technical solution provided by the present invention is as follows: when in use, the first neck support piece 1 and the second neck support piece 2 are wrapped around the outside of the patient's neck to care for the post-surgery area, and the first neck support piece 1 and the second neck support piece 2 are connected and fixed by Velcro, so that the back neck pad 3 on the second neck support piece 2 fits against the back of the patient's neck, and the side protection pad 4 contacts the side of the patient's neck. The chest support area 7 on the first neck support piece 1 corresponds to the patient's chest position, and the annular protection area 6 surrounds the outside of the patient's chin area. The chest pad 5 on the chest support area 7 protects the chest area, and the chin protection pad 11 at the annular protection area 6 supports and protects the patient's chin area to avoid pressure damage to the skin caused by wearing the first neck support piece 1 and the second neck support piece 2.

[0054] When the patient wears the first neck brace 1 and the second neck brace 2 and performs head movements, the chin protection pad 11 will be subjected to pressure from the patient's chin area and adapt to the patient's movements through its own deformation. At the same time, the first connecting plate 18 will also undergo adaptive deformation at the first weakened groove 19, so that a certain inclination is generated between the first connecting plate 18 and the guide rod 20 and the threaded sleeve 16, so that the fixing seat 14 together with the chin protection pad 11 will be tilted as a whole to adapt to the patient's movements.

[0055] When the first cervical support plate 1 and the second cervical support plate 2 become loose as the patient moves, the rotating knob 9 can drive the threaded sleeve 16 to rotate, and then the thread between the threaded sleeve 16 and the threaded rod 21 can push the fixing seat 14 as a whole to slide along the guide tube 10 and the guide rod 20, and then adjust the position of the chin protection pad 11 on the inner side of the annular protection zone 6, and press the chin area of ​​the patient with the chin protection pad 11 to maintain the supporting effect of the first cervical support plate 1 and the second cervical support plate 2 on the neck.

[0056] When the chin protection pad 11 needs to be disassembled and cleaned, the knob 9 is rotated so that the fixing seat 14 drives the chin protection pad 11 to approach the inner wall of the annular protection zone 6 until the clamping joint 22 and the extrusion plate 15 contact each other, and then the knob 9 is continuously rotated to make the first extrusion surface 17 on the extrusion plate 15 fit with the second extrusion surface 23 on the clamping joint 22, and form an extrusion on the second extrusion surface 23. After the second extrusion surface 23 is extruded, the second connecting plate 27 bends and deforms at the second weakened groove 28, so that the second extrusion surface 23 avoids the extrusion plate 15, and the clamping relationship between the clamping joint 22 and the clamping interface 24 is ended, and the connection between the connecting seat 25 and the fixing seat 14 is released. Then, the fixing seat 14 and the connecting seat 25 are separated by the elastic force generated when the second connecting plate 27 recovers its deformation, and the disassembly of the chin protection pad 11 is completed.

[0057] When the disassembled chin protection pad 11 is cleaned and installed, the knob 9 is rotated to make the fixing seat 14 leave the action range of the extrusion plate 15, and the connecting seat 25 on the clean chin protection pad 11 is directly inserted into the fixing seat 14. The connecting seat 25 enters the fixing seat 14, and the card connector 22 contacts and is squeezed with the inner wall of the card interface 24, so that the second connecting plate 27 is deformed at the second weakened groove 28. After the connecting seat 25 is fully docked with the fixing seat 14, the card connector 22 passes through the card interface 24, the second connecting plate 27 resumes its deformation, and the card interface 24 is carded to the outside of the fixing seat 14, so as to realize the connection and fixation between the fixing seat 14 and the connecting seat 25, and complete the use process of the whole nursing equipment for preventing pressure injuries of the skin of patients after interventional surgery.
