Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, specifically to a fall protection device for an interventional catheterization lab. Background Technology

[0002] The interventional catheterization lab is a core medical unit for minimally invasive diagnosis and treatment of cardiovascular diseases, mainly covering procedures such as coronary artery intervention, electrophysiological examination and radiofrequency ablation, and congenital heart disease closure. These procedures are usually performed under local anesthesia combined with moderate sedation. When patients receive stimulation from the diagnostic and treatment devices, they are prone to sudden limb twitching or trunk displacement due to physiological stress response, resulting in unexpected changes in body position and causing patients to fall from the bedside.

[0003] There are many existing technologies for preventing patients from falling off the bed during surgery, such as waist-binding anti-fall restraint belts, which mainly consist of a waist-binding part and a bed-fixing belt. The bed-fixing belt is inserted into the waist-binding part, and both ends of the bed-fixing belt are adjustablely secured to the bed frame with telescopic buckles. During use, the bed-fixing belt can be placed between the patient's back and the bed frame or covered on the patient's abdomen to achieve different degrees of restraint and anti-fall effects.

[0004] However, in practical interventional procedures, patients often need to cooperate with various positional adjustments (not just a single supine position). Existing waist-binding anti-fall-from-bed restraints are difficult to adjust quickly during surgery, and their adjustment operation is complex, inevitably interfering with the surgical process. Therefore, it is necessary to propose an anti-fall-from-bed protection device for interventional catheterization labs to meet the needs of rapid and convenient operation for multiple positional restraints during surgery. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a fall protection device for interventional catheterization labs. This device employs a cross-shaped, encircling restraint structure around the patient's waist, facilitating patient posture adjustment during interventional procedures while maintaining stability and addressing the problem of limited restraint effectiveness in traditional lateral fall-prevention waist-binding techniques.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A fall protection device for an interventional catheterization lab includes an equipment shell installed on the bed frame. The equipment shell is provided with a bed width positioning belt, and the bed width positioning belt is provided with symmetrical strap telescopic components. Each strap telescopic component is provided with a quick-connect connector at its top. Each strap telescopic component is provided with a waist binding loop. Each end of the waist binding loop away from the strap telescopic component is fixedly connected with a quick-connect connector. The strap telescopic component is used to elastically accommodate the corresponding waist binding loop. The waist binding loop is semi-encircled and wrapped around both sides of the patient's waist. The strap telescopic components on both sides, combined with the corresponding waist binding loop, form a cross-shaped encircling restraint on the patient's waist. The elastic accommodating of the waist binding loop by the strap telescopic component enables the waist binding loop to adaptively constrain and adjust the patient's waist according to different body shapes and positions.

[0007] Each of the lumbar support belts integrates a locking component to limit the elastic extension length of the corresponding lumbar support belt; medical staff can adjust the locking component to lock the constraint state of the lumbar support belt to achieve stable fixation of the patient's position during surgery.

[0008] The technical principle of the above solution is as follows: The protective device is installed on a conventional hospital bed through the design of the equipment shell. The equipment shell, combined with the bed width positioning belt, achieves the base positioning of the fall protection technology. Symmetrical strap telescopic components are installed on the bed width positioning belt. The strap telescopic components elastically house the waist restraint belt. The waist restraint belt is connected to the quick-connect connector through a quick-connect plug, forming a cross-shaped circumferential restraint around the patient's waist. Utilizing the elastic storage characteristics of the strap telescopic components, the waist restraint belt can adaptively adjust to different body shapes and positions of the patient. At the same time, the locking component integrated in the strap telescopic components can limit the elastic extension length of the waist restraint belt, making it convenient for medical staff to lock the restraint state during operation to stabilize the patient's position.

[0009] The above approach has the following beneficial effects:

[0010] 1. This method uses two waist straps to form a cross-shaped circumferential restraint structure around the patient's waist. Compared with the traditional transverse waist restraint, the cross-shaped circumferential restraint structure can disperse the restraint force in multiple directions, enhance the restriction effect on trunk displacement, and can be adjusted simultaneously by the two waist straps, improving the convenience of adjusting the restraint ring diameter during the operation.

[0011] 2. This solution uses a strap telescopic component to elastically store the lumbar support belt, allowing the lumbar support belt to automatically adapt to the patient's waist circumference. This meets the constraints of patients of different body types and allows for rapid constraint adjustments during intraoperative positional changes, eliminating the need for frequent manual adjustments and simplifying the adjustment process for medical staff.

[0012] 3. This solution integrates a locking component that can quickly lock or release the telescopic length of the lumbar girdles, meeting the needs of multi-position fixation during surgery, while taking into account both the reliability of the restraint and the convenience of position adjustment.

[0013] Furthermore, the belt extension component includes a belt housing fitted onto the bed width positioning belt. Each belt housing is fixedly connected to a rope winding rod, and each rope winding rod is rotatably connected to a rope winding drum. The waist belt is wound around the corresponding rope winding drum. Each rope winding drum is equipped with a torsion spring, and the two ends of the torsion spring are secured to the inner side wall of the rope winding drum and the outer side wall of the rope winding rod.

[0014] Beneficial effects: Due to the elastic restoring force of the torsion spring, the lumbar support belt can always maintain a contraction trend, achieving automatic tightening and adaptive adjustment, thereby improving the stability, comfort, and adaptability of the lumbar support belt for the patient's waist.

[0015] Furthermore, the tape housing is slidably connected to the bed width positioning belt, and an adjusting locking component is fixedly connected to the tape housing. The adjusting locking component is used to lock the relative position of the tape housing on the bed width positioning belt.

[0016] Beneficial effects: By adjusting the relative position of the locking mechanism to lock the housing, the two strap telescopic components can move laterally and be fixed on the bed width positioning belt; this allows medical staff to adjust the overall restraint position according to the patient's body width, optimizing fit and comfort, while ensuring even distribution of restraint force and reducing secondary injuries to the patient caused by localized pressure from restraint.

[0017] Furthermore, the locking assembly includes a ratchet fixedly connected to one side of the rope drum, a locking button embedded in the side wall of the tape housing, the locking button being slidably connected to the tape housing, and a ratchet protrusion fixedly connected to the bottom of the locking button, the ratchet protrusion being able to engage with the ratchet to limit the rotation of the ratchet.

[0018] Beneficial effects: When medical staff press the locking button, the protrusion of the design engages with the ratchet tooth groove, restricting the rotation of the ratchet and the rope drum, thereby locking the extension length of the two waist straps, realizing the quick locking and unlocking of the cross-shaped circumferential restraint during surgery, and facilitating immediate fixation after the patient's position is adjusted during surgery.

[0019] Furthermore, the quick-connect fittings are all hinged to the top of the corresponding nanotube housing.

[0020] Beneficial effects: The quick-connect connector is hinged to the housing of the lumbar belt, which allows the traction direction of the lumbar belt to be adaptively adjusted according to changes in the patient's body position, reducing friction and torsional stress, improving the comfort of the restraint, and facilitating the docking operation of the quick-connect connector.

[0021] Furthermore, each waist belt is equipped with a restraint pouch assembly on its inner wall. The restraint pouch assembly is used to buffer the restraint reaction force generated by the patient's sudden struggle.

[0022] The restraint bag assembly contains a pneumatic acquisition component for collecting the patient's intention to break free, and the strap housing contains a restraint adjustment component for adjusting the angle of the quick-connect fitting. The restraint adjustment component adjusts the angle of the quick-connect fitting based on the patient's intention to break free collected by the pneumatic acquisition component to achieve dynamic adjustment of the restraint force of the lumbar strap.

[0023] Beneficial effects: The restraint bag assembly is equipped with an air pressure acquisition component to monitor the patient's intention to break free in real time. The restraint adjustment component dynamically adjusts the angle of the quick-connect connector based on the acquired signal, changing the binding force of the waist belt, thus realizing intelligent dynamic restraint adjustment. This reduces harm to the patient when a sudden attempt to break free occurs while ensuring restraint stability, improving the effectiveness of preventing falls from the bed and enhancing patient comfort.

[0024] Furthermore, the restraint bladder assembly includes a pressure-bearing airbag, which is sewn onto the inner wall of the corresponding waist belt.

[0025] Beneficial effects: The pressure-bearing airbag is in direct contact with the patient's body surface. The pressure is dispersed by the deformation of the pressure-bearing airbag, reducing friction with the patient's body surface and providing cushioning when the patient struggles. At the same time, the pressure change inside the pressure-bearing airbag can be used as a monitoring signal.

[0026] Furthermore, the air pressure acquisition component includes an air pressure sensor and a controller fixedly connected inside the pressure-bearing airbag, with the air pressure sensor and controller connected by signals.

[0027] Beneficial effects: The air pressure sensor collects the air pressure changes of the airbag in real time and transmits them to the controller. The controller identifies the patient's limb movement characteristics through signal processing, providing an accurate basis for subsequent restraint adjustment and realizing closed-loop control.

[0028] Furthermore, the air pressure sensor is used to collect real-time air pressure change data inside the airbag and transmit the air pressure signal to the controller. The controller compares the deviation amplitude and rate of change between the real-time air pressure value and the preset baseline value, and combines waveform feature analysis to identify the instantaneous air pressure fluctuation caused by the patient's sudden limb movement, thereby determining whether the patient has the intention to break free.

[0029] Beneficial effects: The controller compares the deviation and rate of change of real-time air pressure with the preset baseline value, and combines waveform feature analysis to identify instantaneous air pressure fluctuations caused by sudden limb movements of the patient, thereby determining the intention to break free, improving monitoring accuracy, and reducing the probability of false triggering causing discomfort to the patient.

[0030] Furthermore, the constraint adjustment assembly includes a signal brake embedded in the top of the nanobelt housing, the output end of the signal brake being hinged to a quick-connect connector, and the signal brake being signal-connected to the controller.

[0031] Beneficial effects: The signal brake adjusts the angle of the hinge end with the quick-connector according to the controller command, changes the traction direction and tension of the waist belt, and realizes dynamic adjustment of the restraint force, so that the cross-shaped restraint has the ability to dynamically respond to the patient's intention to break free, which ensures safety and improves comfort.

[0032] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The following detailed description illustrates the specific implementation method:

[0044] Example 1:

[0045] This embodiment provides a fall protection device for an interventional catheterization lab, specifically as follows: Figure 1 and Figure 2 As shown, the device includes a housing 1 installed on the bed frame, a bed width positioning belt 2 on the housing 1, and two fixing platforms 101 that are bolted to both sides of the bed frame. Both ends of the bed width positioning belt 2 are fixed to the fixing platforms 101 by screws. Medical staff can adjust the position of the fixing platforms 101 on both sides of the bed frame to accommodate the waist width of patients with different heights.

[0046] Combination Figure 2 and Figure 3 As shown, the bed width positioning belt 2 is equipped with two strap telescopic components 3; each strap telescopic component 3 includes a strap housing 301 that is slidably connected to the bed width positioning belt 2. A rope winding rod 302 is fixedly installed inside the strap housing 301. A rope winding drum 303 is rotatably connected to the rope winding rod 302 through a bearing. A waist binding ring belt 4 is wound around the rope winding drum 303. A torsion spring 304 is installed inside the rope winding drum 303. The two ends of the torsion spring 304 are fixed to the inner side wall of the rope winding drum 303 and the outer side wall of the rope winding rod 302. Due to the presence of the torsion spring 304, the waist binding ring belt 4 has a pre-stress that allows it to retract back into the strap housing 301. At the same time, medical staff can still adjust the binding circumference by pulling the waist binding ring belt 4.

[0047] The end of each lumbar support belt 4 away from the winding drum 303 is fixedly connected to a quick-connect plug 5 by screws. A quick-connect connector 6 is hinged to the top of each belt housing 301. The lumbar support belts 4 are wrapped around the patient's waist in a circular motion. (In this embodiment, a belt opening 401 is provided on the lumbar support belt 4 inside the left belt housing 301. The illustration shows the lumbar support belt 4 on the right side passing through the belt opening 401 and wrapping around the patient's waist with the lumbar support belt 4 on the left side.) Figure 5 As shown), the quick-connect plug 5 is fastened to the corresponding quick-connect connector 6 to achieve a limiting restraint on the patient's waist (compared to conventional wearable anti-fall bed restraint technology, the quick-connect connection reduces the complexity of preoperative installation and achieves convenient anti-fall protection installation); before the interventional surgery, the medical staff pulls and adjusts the waist belts 4 on both sides to wrap around the patient's waist in a semi-encircling manner. Under the action of the torsion springs 304 on both sides, the two waist belts 4 apply a cross-encircling restraint to the patient's waist.

[0048] Specifically, the sliding connection between the strap housing 301 and the bed width positioning belt 2 is as follows: an adjusting locking element 7 is fixedly connected to the strap housing 301. The adjusting locking element 7 is used to lock the relative position of the strap housing 301 on the bed width positioning belt 2, that is, to limit the relative sliding of the strap housing 301 and the bed width positioning belt 2. The adjusting locking element 7 is preferably a hook-and-loop buckle, and the bed width positioning belt 2 has several adjustment holes corresponding to the hook-and-loop buckles. By adjusting the position of the two strap housings 301 on the bed width positioning belt 2, the comfort of restraint for patients with different body widths can be adjusted.

[0049] The two lumbar straps 4 are arranged in a cross-shaped, encircling restraint pattern. Combined with the positional limitation of this restraint on the bed width positioning belt 2, it can effectively fix the patient on the bed (i.e., meet the fall prevention requirement), and can also adapt to the need for restraint in multiple positions during surgery by allowing the extension and retraction of the two lumbar straps 4. At the same time, by temporarily unlocking the extension and retraction of the lumbar straps 4 during surgery, the patient's position can be quickly adjusted. After the position adjustment is completed, the extension and retraction length of the lumbar straps 4 can be locked again under the elastic adjustment of the torsion spring 304 to restore the restraint state, thus taking into account both the convenience of intraoperative position adjustment and the reliability of restraint.

[0050] Regarding the extension limit of waist belt 4, the details are as follows: Figure 3 Combination Figure 4 As shown, in this embodiment, a locking component 8 for limiting the elastic extension and retraction of the corresponding waist belt 4 is integrated on the belt housing 301. The locking component 8 includes a ratchet 801 welded to one side of the rope drum 303. A locking button 802 is embedded in the side wall of the belt housing 301. The locking button 802 is slidably connected to the belt housing 301. A ratchet protrusion 803 is welded to the bottom of the locking button 802. When the locking button 802 is pressed, the ratchet protrusion 803 can adapt to and engage the rotation of the limiting ratchet 801, thereby limiting the extension and retraction of the waist belt 4.

[0051] Example 2:

[0052] During the intraoperative positioning process using a cross-shaped circumferential restraint structure (taking the patient's position from supine to lateral decubitus as an example), the friction between the patient's clothing and the lumbar circumferential band 4 can easily lead to unexpected differences in the adjustment length of the two lumbar circumferential bands 4, resulting in uneven distribution of the restraint force on both lumbar circumferential bands 4, which weakens the stability and balance of the overall restraint and fall prevention effect.

[0053] Therefore, as attached Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that restraint bladder assemblies are provided on the inner wall of the waist belt 4, and each restraint bladder assembly includes a pressure-bearing airbag 9, which is sewn onto the corresponding inner wall of the waist belt 4. After the pressure-bearing airbag 9 comes into contact with the patient's body surface, on the one hand, it can reduce the frictional resistance between the waist belt 4 and the patient's body surface during the body position adjustment process. Under the synergistic effect of the elastic restoring force of the torsion springs 304 on both sides, it can improve the consistency of the length of the waist belt 4 on both sides during the extension and retraction adjustment process, thereby optimizing the balanced distribution of restraint force. On the other hand, the pressure-bearing airbag 9 can provide a cushioning effect when the patient makes a sudden limb movement, reducing the risk of secondary injury that may be caused by a sudden increase in restraint force.

[0054] Based on the buffering effect of the pressure-bearing airbag 9 on the restraining reaction force generated by the patient's sudden limb movements, the pressure-bearing airbag 9 can also be used to monitor the patient's intention to break free. Behavioral perception under restraint is achieved through the feedback of air pressure fluctuations within the pressure-bearing airbag 9. To this end, this embodiment is equipped with an air pressure acquisition component for collecting the patient's intention to break free within the pressure-bearing airbag 9. The air pressure acquisition component includes an air pressure sensor and a controller (not shown in the figure) fixedly connected within the pressure-bearing airbag 9. The air pressure sensor is signal-connected to the controller. When the patient makes a sudden limb movement, the cross restraint structure (a wrap-around structure composed of two waist straps 4) acts on the pressure-bearing airbag 9 at the patient's waist, causing it to deform and resulting in changes in its internal air pressure. The air pressure sensor is used to collect the air pressure change data inside the pressure-bearing airbag 9 in real time and transmit the air pressure signal to the controller. The controller compares the deviation amplitude and rate of change between the real-time air pressure value and the preset baseline value, and combines waveform feature analysis to identify the instantaneous air pressure fluctuation caused by the patient's sudden limb movements, thereby determining whether the patient has an intention to break free.

[0055] Since the quick-connect connector 6 and the tape housing 301 are hinged, the tape housing 301 is provided with a constraint adjustment component for adjusting the angle of the quick-connect connector 6. Figure 5 and Figure 6As shown, the restraint adjustment assembly includes a signal brake 10 embedded in the top of the housing 301. The output end of the signal brake 10 is hinged to the quick-connect joint 6. The signal brake 10 is signal-connected to the controller. Based on the patient's intention to break free signal collected by the barometric pressure sensor, the signal brake 10 responds to the control command by adjusting the angle of the hinged end with the quick-connect joint 6 to dynamically adjust the restraint force of the lumbar strap 4. This allows the restraint formed by the two lumbar straps 4 to adaptively adjust the restraint strength according to the patient's real-time behavioral state. That is, when a sudden limb movement or tendency to break free is detected, the controller triggers the signal brake 10 to actively adjust the angle of the quick-connect joint 6, increasing the tension of the lumbar strap 4 to enhance restraint stability; after the patient returns to a stable state, the controller drives the signal brake 10 to reduce the restraint force.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
