Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a cleaning device for bedridden patients after anterior cervical vertebrae surgery in orthopedics. Background Art

[0002] Anterior cervical spine surgery (ACDF) is the mainstream surgical procedure for the treatment of cervical spondylosis, cervical disc herniation and other diseases. It has the advantages of less trauma and quick recovery. The number of cases of anterior cervical spine surgery in my country has exceeded 300,000 per year. After anterior cervical spine surgery, patients need to stay in bed for 3-7 days. During this period, patients need to be cleaned and cared for to reduce the incidence of pressure sores. The patient is in a bedridden state and his or her movements are limited, but the patient's pressure sores often occur in the patient's pressure area, that is, the patient's back. Therefore, when cleaning the patient, it is necessary to focus on cleaning the patient's back.

[0003] Since patients are not able to move easily, they need external force to turn over. At present, in order to reduce the labor intensity of nursing staff, some hospitals use special cleaning devices to assist nursing staff in cleaning the back of patients. Most of these cleaning devices use a driving mechanism to drive the push plate to move, and use the thrust of the push plate to assist the patient to turn over. After the patient turns over, the cleaning mechanism is used to clean the patient's back.

[0004] However, when traditional cleaning devices push patients to turn over, the thrust of the push plate directly acts on the patient's body parts, which will directly exert pressure on the patient's lumbar spine. The maximum stress of the C5-C6 segment of the patient's lumbar spine reaches 2.1MPa (Journal of Biomedical Engineering, 2024), and the patient's lumbar lordosis angle exceeds the limit rate, which causes the pressure to be directly transmitted to the patient's cervical spine, easily causing secondary injury to the surgical site of the patient's cervical spine. Clinical studies have found that repeatedly pushing patients to turn over increases the risk of secondary injury to the patient's cervical spine by 40% (J Neurosurg Spine, 2023). Summary of the invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and provide a cleaning device for bedridden patients after orthopedic anterior cervical spine surgery.

When the support plate drives the patient's body to roll over, the double-headed hydraulic cylinder drives two guard plates to clamp the patient's body on both sides. Since the guard plates are in close contact with the patient's body, sufficient supporting force can be applied to the patient's body to prevent the patient's body from shaking and to prevent the patient's cervical and lumbar vertebrae from being stressed, thereby further preventing secondary injury to the patient's neck during the rollover.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-Figure 8 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] like Figure 1-Figure 8 As shown, the cleaning device for bedridden patients after orthopedic cervical anterior surgery provided by the present invention comprises a bed body 101 and a cleaning mechanism 102, wherein the cleaning mechanism 102 is used to clean the patient's body, and further comprises: a support plate 103, a telescopic mechanism 105, a first driving mechanism 106 and a guard plate 107, wherein the support plate 103 is used to support the patient, and the support plate 103 is provided with a long strip through groove 104 along the length direction of the bed body 101; the telescopic mechanism 105 is arranged in the through groove 104, and the telescopic mechanism 105 can be telescoped along the length direction of the through groove 104, and when the telescopic mechanism 105 is extended The telescopic mechanism 105 can apply a supporting force to the patient's body, and the cleaning mechanism 102 is arranged on the telescopic mechanism 105. When the telescopic mechanism 105 contracts, the telescopic mechanism 105 drives the cleaning mechanism 102 to clean the patient's body; the first driving mechanism 106 is connected to the support plate 103, and the first driving mechanism 106 is used to drive the support plate 103 to rotate around the length direction of the bed body 101; the guard plate 107 is arranged on one side of the support plate 103 along its own width direction, and the guard plate 107 is used to apply a supporting force to one side of the patient's body when the support plate 103 rotates.

[0034] The working principle of the above embodiment is briefly described:

[0035] When the device is in use, the patient lies on the support plate 103, which is provided with a mattress to improve the patient's comfort. The patient's head is facing the head of the bed body 101, and the telescopic mechanism 105 in the through slot 104 is in an extended state. The telescopic mechanism 105 applies a supporting force to the patient's body. At this time, the patient's chest and abdomen can be cleaned. After the chest and abdomen of the patient are cleaned, the first driving mechanism 106 is used to drive the support plate 103 to rotate around the length direction of the bed body 101, thereby driving the patient's body to roll over. In this process, the guard plate 107 on one side of the support plate 103 applies a supporting force to one side of the patient's body. When the support plate 103 drives the patient's body to rotate ninety degrees to complete the side rollover, since the mattress on the support plate 103 is no longer under the pressure of the patient's body, after the support plate 103 rotates ninety degrees, the mattress on the support plate 103 can easily slide from the upper side of the support plate 103 to the lower side of the support plate 103. At this time, the patient's body is directly facing the telescopic mechanism 105, and then, the telescopic mechanism 105 is controlled to move and contract, so that the through slot 104 is opened. Since the patient is in a side rollover position at this time, the guard plate 107 provides sufficient supporting force for the patient. Therefore, after the through slot 104 is opened, it will not affect the supporting force on the patient's body. The patient's body can still receive sufficient supporting force from the guard plate 107, so that the patient's cervical and lumbar vertebrae will not be overstressed, thereby preventing the patient from causing damage to the neck wound when turning over. When the through slot 104 is opened, the patient's back is exposed. At this time, the patient's back can be cleaned through the cleaning mechanism 102, and it is convenient for the patient to turn over. It can prevent the patient's cervical spine from bending in the four directions of front, back, left and right when turning over, and it can also prevent the neck wound from being contaminated by water. At the same time, it can prevent water from entering the ears, and the patient can get a higher degree of comfort while ensuring that the back is clean.

[0036] The cleaning device for bedridden patients after orthopedic cervical anterior surgery of the present invention can prevent excessive stress on the cervical and lumbar vertebrae of bedridden patients during the process of turning over when cleaning the back of the body of the bedridden patients after orthopedic cervical anterior surgery, thereby avoiding secondary damage to the surgical site on the patient's neck when cleaning the patient's back.

[0037] On the basis of the above embodiments, in order to further prevent the patient's neck surgical wound from being damaged due to the bending of the cervical and lumbar vertebrae during the rollover process.

[0038] like Figure 3 , Figure 5 , Figure 6 and Figure 8As shown, the telescopic mechanism 105 includes a second driving mechanism and a plurality of connecting shafts 201, the side wall of the through slot 104 is provided with a slide slot 202 along the length direction of the bed body 101, and the plurality of connecting shafts 201 are arranged in parallel and arranged along the length direction of the bed body 101, and each connecting shaft 201 is arranged along the width direction of the bed body 101 and is slidably connected in the slide slot 202, and the cleaning mechanism 102 is arranged on the connecting shaft 201, and the connecting shaft 201 near the head end of the bed body 101 is connected to the second driving mechanism, and the connecting shaft 201 near the tail end of the bed body 101 is fixed, and a plurality of V-shaped connecting rod mechanisms 203 arranged in parallel are connected between two adjacent connecting shafts 201, and when the second driving mechanism drives the plurality of connecting shafts 201 away from each other, the V-shaped connecting rod mechanism 203 is unfolded to close the through slot 104.

[0039] When the patient lies on the support plate 103, the second driving mechanism is controlled to move forward, and the second driving mechanism drives the connecting shaft 201 near one end of the bedside to move toward the other end of the bedside, thereby increasing the distance between the connecting shaft 201 near one end of the bedside and its adjacent connecting shaft 201, and the V-shaped connecting rod mechanism 203 is unfolded, thereby generating a pulling force on the connecting shaft 201 adjacent to it. Similarly, the distance between multiple connecting shafts 201 is increased until multiple parallel V-shaped connecting rod mechanisms 203 are fully unfolded to block the through groove 104. At this time, the unfolded multiple parallel V-shaped connecting rod mechanisms 203 can exert sufficient supporting force on the patient's body. When the patient rolls over, the second driving mechanism is controlled to move in the opposite direction, and the second driving mechanism drives the connecting shaft 201 near the head of the bed to move toward the foot of the bed, thereby reducing the spacing between the multiple connecting shafts 201, and the V-shaped connecting rod mechanism 203 shrinks, thereby opening the through slot 104. In this process, since the cleaning mechanism 102 is arranged on the connecting shaft 201, the cleaning mechanism 102 can clean the entire back of the patient as the connecting shaft 201 moves. And since the multiple connecting shafts 201 are arranged in parallel and arranged along the length direction of the bed body 101, each connecting shaft 201 is arranged along the width direction of the bed body 101 and is slidably connected in the slide slot 202. Therefore, under the support of the multiple connecting shafts 201, sufficient supporting force can be applied to the patient's body through the V-shaped connecting rod mechanism 203 during the patient's rollover, further preventing the patient from suffering secondary neck injury due to the bending of the cervical and lumbar vertebrae during the rollover.

[0040] As a preferred solution, Figure 5 and Figure 8As shown, the second driving mechanism includes a lead screw 301 and a power device, and the multiple connecting shafts 201 are each provided with a first slider 302, the first slider 302 is slidably connected in the slide groove 202, the first slider 302 near the head end is provided with a threaded hole, and the first slider 302 near the foot end is fixed in the slide groove 202, the lead screw 301 is arranged parallel to the slide groove 202, the first slider 302 near the head end is connected to the lead screw 301 through a threaded hole, and the power device is connected to the lead screw 301. When the second driving mechanism drives the connecting shaft 201 to move, the power device drives the lead screw 301 to rotate by controlling the action of the power device. When the lead screw 301 rotates, it drives the first slider 302 near the head end to slide in the slide groove 202 through the threaded hole. Since the slide groove 202 is arranged along the length direction of the bed body 101, the first slider 302 near the head end is driven to move toward the head or foot end of the bed. Driven by multiple V-shaped connecting rod mechanisms 203, multiple connecting shafts 201 move toward the head or foot end of the bed, thereby causing the entire telescopic mechanism 105 to expand or contract.

[0041] As a preferred solution, Figure 1-Figure 5 and Figure 7 As shown, both sides of the support plate 103 are provided with guard plates 107, and the bottom end of the support plate 103 is provided with a double-headed hydraulic cylinder 401, and the double-headed hydraulic cylinder 401 is connected with a hydraulic control circuit, and the two pistons 402 of the double-headed hydraulic cylinder 401 are respectively connected with the guard plates 107 on both sides of the support plate 103, and the double-headed hydraulic cylinder 401 is used to drive the two guard plates 107 to move closer to each other or away from each other. When the support plate 103 assists the patient to turn over, the hydraulic control circuit is first controlled to move, and the hydraulic control circuit controls the double-headed hydraulic cylinder 401 to drive the two guard plates 107 to move closer to each other until the two guard plates 107 clamp the two sides of the patient's body. At this time, when the support plate 103 drives the patient's body to turn over, because the guard plates 107 are in close contact with the patient's body, sufficient support force can be applied to the patient's body to prevent the patient's body from shaking, and to prevent the patient's cervical and lumbar vertebrae from being stressed, thereby further preventing secondary injury to the patient's neck when turning over.

[0042] As a preferred solution, Figure 1 , Figure 2 and Figure 6As shown, a hydraulic clamping mechanism 5 is provided at one end of the support plate 103 near the head of the bed, and the hydraulic clamping mechanism 5 is provided at the middle position along the width direction of the support plate 103. The hydraulic clamping mechanism 5 is connected to the hydraulic control circuit. When the hydraulic control circuit controls the double-headed hydraulic cylinder 401 to drive the two guard plates 107 to approach each other, the hydraulic control circuit controls the hydraulic clamping mechanism 5 to clamp the patient's neck at the middle position along the width direction of the support plate 103. In the process of the patient's body turning over, by controlling the action of the hydraulic control circuit, when the hydraulic control circuit controls the double-headed hydraulic cylinder 401 to drive the two guard plates 107 to clamp the patient's body, the hydraulic clamping mechanism 5 clamps the patient's neck, thereby preventing the patient's head and neck from shaking when turning over, thereby preventing the patient's head and neck from shaking and causing secondary injury to the patient's neck.

[0043] As a preferred solution, Figure 1-Figure 7 As shown, the first driving mechanism 106 includes an arc-shaped slide groove 601, a gear ring 602 and a transmission shaft 603, the arc-shaped slide groove 601 is arranged at the end of the head of the bed, the axis line of the arc-shaped slide groove 601 is parallel to the length direction of the support plate 103, and a plurality of second sliders 604 are slidably connected in the arc-shaped slide groove 601, and the plurality of second sliders 604 are all fixedly connected to the end of the support plate 103, the gear ring 602 is fixedly connected to the end of the bed body 101 and is coaxially arranged with the arc-shaped slide groove 601, the transmission shaft 603 is pivotally connected to a second slider 604, and the transmission shaft 603 is gear-connected with the gear ring 602 through a gear 605. When the patient's body needs to be turned sideways, the transmission shaft 603 is driven to rotate, and the transmission shaft 603 drives the gear 605 to rotate. Under the action of the ring gear 602, the gear 605 rolls on the ring gear 602, thereby driving the multiple second sliders 604 to slide in the arc-shaped slide groove 601, thereby driving the support plate 103 to rotate. With the support of the multiple second sliders 604, the stability of the rotation of the support plate 103 can be guaranteed, thereby further preventing the patient's body from shaking.

[0044] As a preferred solution, Figure 1 , Figure 3 , Figure 5 and Figure 8As shown, the cleaning mechanism 102 includes a brush pad 701 and a cleaning agent supply device, the brush pad 701 is arranged at one end where the V-shaped connecting rod mechanism 203 is connected to the connecting shaft 201, when the lead screw 301 drives multiple connecting shafts 201 to approach each other, the brush pad 701 contacts the patient's body, the connecting shaft 201 is provided with a liquid hole 703, the liquid hole 703 is connected to the cleaning agent supply device, the V-shaped connecting rod mechanism 203 is provided with a nozzle 702 at one end where the connecting shaft 201 is connected, the nozzle 702 is connected to the liquid hole 703. After the patient's body is turned sideways, the power device is controlled to drive the screw 301 to rotate, thereby driving multiple connecting shafts 201 to approach each other. The brush pad 701 located at one end of the V-shaped connecting rod mechanism 203 connected to the connecting shaft 201 comes into contact with the patient's body. Driven by the connecting shaft 201, the patient's body can be wiped. At the same time, the cleaning agent supply device introduces cleaning agent into the liquid hole 703 on the connecting shaft 201. The cleaning agent is sprayed out through the liquid hole 703 and the nozzle 702 on the V-shaped connecting rod mechanism 203. Combined with the wiping of the brush pad 701, the patient's body can be cleaned while leaking out of the through groove 104.

[0045] As a preferred solution, Figure 8 As shown, a pressure valve 8 is provided in the nozzle 702, and the pressure valve 8 is connected to the nozzle 702. When the brush pad 701 contacts the patient's body, the pressure valve 8 contacts the patient's body and is opened under pressure, and the cleaning agent is sprayed out from the nozzle 702. By setting the pressure valve 8, when the multiple connecting shafts 201 are close to each other, the brush pad 701 contacts the patient's body and wipes the patient's body. At the same time, the pressure valve 8 also contacts the patient's body and is opened under pressure, and the cleaning agent is sprayed out from the nozzle 702, so that the cleaning agent is sprayed on the patient's body; when the telescopic mechanism 105 is unfolded, that is, when the multiple connecting shafts 201 are away from each other, the brush pad 701 does not contact the patient's body. At this time, the pressure valve 8 is not pressed and is in a closed state, so the nozzle 702 will not spray the cleaning agent, so that the automatic control of the cleaning agent spraying can be realized, and the cleaning agent is prevented from being wasted when the cleaning agent is continuously sprayed.

[0046] As a preferred solution, Figure 6 and Figure 7 As shown, the transmission shaft 603 is provided with a self-locking mechanism, and the self-locking mechanism is used to lock the position of the gear 605 on the gear ring 602. By providing the self-locking mechanism, when the patient's body is turned sideways, the position of the gear 605 on the gear ring 602 is locked by the self-locking mechanism, so that the posture of the patient's body can be fixed, so as to prevent the support plate 103 from shaking when the patient's body is washed, thereby preventing the patient's neck wound from being injured due to body shaking.

[0047] As a preferred solution, Figure 2 As shown, the hydraulic clamping mechanism 5 is provided with a rubber pad 9, and the hydraulic clamping mechanism 5 clamps the patient's neck through the rubber pad 9. By providing the rubber pad 9, the hydraulic clamping mechanism 5 clamps the patient's neck through the rubber pad 9, which can cushion the patient's neck and prevent the patient's neck from being injured due to excessive clamping force.

[0048] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
