Description

Technical Field

[0001] The present invention relates to the technical field of post-intervention nursing, and in particular to a device and system for post-intervention limb nursing. Background Art

[0002] Interventional surgery is a minimally invasive method of diagnosing and treating diseases through the body's natural cavities or tiny channels, using special catheters, guidewires and other precision instruments under the guidance of medical imaging equipment.

[0003] After interventional surgery, patients usually need to remain in the supine position and implement immobilization measures on the limb on the operated side for at least 6 hours. For patients with more serious conditions, they may need to rest in bed for a longer period of time after surgery. During this period, since the lower limbs are in an immobilized state for a long time, it is difficult to perform effective massage care. Patients often feel discomfort in the lower limbs and the possibility of deep vein thrombosis. In addition, if the airbag is used to apply pressure to restrict the affected limb, the airbag and the affected limb are in close contact for a long time, which may cause local skin compression and ischemia, thereby increasing the risk of skin injuries such as pressure sores.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] like Figure 1 - Fig.12 As shown, the present invention provides:

[0055] A post-interventional limb care device comprises a hip plate 10 and a clamping tool 20 mounted at the edge of the hip plate 10, a leg restraining unit 60 is detachably fixed to the end of the hip plate 10, the clamping tool 20 comprises a clamping frame 21 connected to the hip plate 10, an adjusting stud is threadedly connected to the lower surface of the clamping frame 21, one end of the adjusting stud inserted into the clamping frame 21 is rotatably connected to a clamping plate 22, and the hip plate 10 is fixed to the bed through the clamping plate 22;

[0056] Specifically, in actual use, the hip board 10 and the leg restraint unit 60 are first placed flat on the bed, and during the placing process, they are pushed from the edge to the middle. In this way, when the hip board 10 is placed in the middle of the bed, the clamping frame 21 will be clamped at the edge of the bed. At this time, the adjusting studs are rotated to move the clamping plate 22 upward, and then against the bottom of the bed, so that the position of the hip board 10 is fixed to avoid displacement during braking.

[0057] like Figure 1 , Figure 2 and Figure 3As shown, a compression unit 30 is mounted on the buttocks plate 10, and the compression unit 30 includes a compression airbag 32, which can compress the puncture point after being inflated;

[0058] In further detail, when inflating, the front three-way solenoid valve 52 is first adjusted to connect the delivery tube with the first inflation tube 53, and then the air pump 51 is started to inflate the compression airbag 32 through the first inflation tube 53, thereby compressing the puncture point;

[0059] The compression unit 30 also includes a push-up member 31 inserted into the hip plate 10, and the compression airbag 32 is assembled on the push-up member 31. A slot 33 is opened at the edge of the surface of the hip plate 10, and the push-up member 31 is fixed in the slot 33 by a knob bolt;

[0060] Specifically, a plurality of laterally distributed positioning screw holes are provided on the top of the inner wall of the slot 33, and a plurality of groups of vertically distributed mounting screw holes that are compatible with the positioning screw holes are provided on one side of the support member 31. By matching the mounting screw holes at different positions with the positioning screw holes at different positions, the support member 31 can be fixed in position after being adjusted up and down and left and right, so that the position of the compression airbag 32 can be adjusted according to the position of the patient.

[0061] like Figure 2 and Figure 3 As shown, a leg restraint unit 60 is detachably fixed to the end of the hip plate 10, and the leg restraint unit 60 includes a restraint member 61 connected to the hip plate 10, and a side airbag 62 and a bottom airbag 63 are respectively mounted on the inner side wall and the inner bottom wall of the restraint member 61, and the side airbag 62 can restrain the patient's affected limb after being inflated, and a temperature sensor and a pressure sensor are both arranged on the side airbag 62 and the bottom airbag 63;

[0062] Both sides and the bottom of the restricting member 61 are equipped with an air intake control assembly 40 by opening an air supply cavity 64. The air intake control assembly 40 includes a main pipe 41 inserted into the air supply cavity 64, and a control pipe 42 is rotatably connected to the main pipe 41.

[0063] After the control tube 42 is rotated to different angles, it can supply air to the side airbags 62 and the bottom airbags 63 at different positions, so as to realize dynamic adjustment according to different positions of the affected limb. At the same time, by supplying different amounts of air to the bottom airbags 63 at different positions, the bottom airbags 63 are tilted downward or upward as a whole, so as to promote the movement of the affected limb.

[0064] One end of the control tube 42 is equipped with a rotating joint 43, and a rotating portion 44 is fixedly sleeved on the surface of the control tube 42. A limiting ring is sleeved on the outer surface of the rotating portion 44, and one end of the limiting ring is fixed to the limiting member 61. In particular, under the action of the rotating joint 43, when the rotating portion 44 is held to drive the control tube 42 to rotate, the second inflation tube 54 at the other end of the joint will not rotate with it;

[0065] A spring is mounted on the outer wall of the rotating part 44 through a mounting hole, and a clamping column is fixed on one end of the spring. A plurality of limiting holes distributed in a circumferential array are opened on the outer wall of the limiting ring, and the clamping column is matched with the limiting holes, so that the position of the control tube 42 can be fixed after the rotating part 44 drives the control tube 42 to rotate to a required angle. Preferably, a closing hole matched with the clamping column is opened on the outer wall of the limiting ring between two of the limiting holes.

[0066] In further detail, after the control tube 42 is rotated 72°, the clamping column will be engaged in the limiting hole at the corresponding position under the drive of the spring, thereby fixing the position of the control tube 42. In this state, inflation is performed again. When the inflation is completed, the control tube 42 is rotated until the clamping column is engaged in the closing hole. At this time, the air supply hole 46 on the surface of the control tube 42 is in a covered state, and is not connected to the synchronous air outlet hole 45 or the separate air outlet hole 47 on the surface of the main tube 41. At this time, the bulging state of the side airbag 62 and the bottom airbag 63 can be maintained.

[0067] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.11 As shown, a plurality of synchronous air outlet holes 45 are opened on one side of the outer wall of the main pipe 41, and air supply holes 46 corresponding to the synchronous air outlet holes 45 are opened on one side of the control pipe 42. The air supply holes 46 are evenly divided into four groups, and each group is located in an air supply cavity 64 at a different position. A sealing cover is detachably fixed on the inner wall of the air supply cavity 64;

[0068] Four groups of separate air outlet holes 47 are also provided on the outer wall of the main pipe 41, so that after the control pipe 42 is rotated 72 degrees, the air supply hole 46 is connected with the separate air outlet holes 47 at different positions, so that air can be supplied to the air supply chambers 64 at different positions separately;

[0069] Specifically, the outer wall of the main tube 41 is evenly divided into four areas, namely, area A, area B, area C, and area D. Each area corresponds to an air delivery cavity 64. The circumference of each area is divided into five parts, and the 0° scale line, the 72° scale line, the 144° scale line, the 216° scale line, and the 288° scale line are respectively delimited in the clockwise direction.

[0070] In order to achieve the communication between the synchronous air outlet holes 45 on the main pipe 41 and the air supply holes 46 on the control pipe 42, the synchronous air outlet holes 45 are opened on the 0° scale line in each area. In order to enable the air supply holes 46 to communicate with the separate air outlet holes 47 at different positions after the control pipe 42 is rotated 72° each time, so that each chamber can be independently air-intaked, a first group of separate air outlet holes 47 is opened at the 72° scale line in the A area, a second group of separate air outlet holes 47 is opened at the 144° scale line in the B area, a third group of separate air outlet holes 47 is opened at the 216° scale line in the C area, and a fourth group of separate air outlet holes 47 is opened at the 288° scale line in the D area;

[0071] In particular, the positions of the limiting holes correspond to the 0° scale line, the 72° scale line, the 144° scale line, the 216° scale line and the 288° scale line, so that the personnel can know the rotation angle when rotating.

[0072] like Figure 1 , Figure 2 and Figure 3 As shown, the air intake control assembly 40 also includes an air charging and discharging assembly 50 mounted on the outer wall of the clamping tool 20;

[0073] The inflation and deflation assembly 50 includes an air pump 51 mounted on the clamping fixture 20. The output end of the air pump 51 is connected to a front three-way solenoid valve 52 through a delivery pipe. One end of the front three-way solenoid valve 52 is connected to the compression airbag 32 through a first inflation pipe 53. The other end of the front three-way solenoid valve 52 is connected to a rear three-way solenoid valve 55 through an air delivery pipe.

[0074] A protective cover is clamped on the outer wall of the clamping frame 21. In particular, the protective cover is used to shield and protect the air pump 51, the front three-way solenoid valve 52 and the rear three-way solenoid valve 55.

[0075] The two ends of the rear three-way solenoid valve 55 are respectively fixed with a second inflation tube 54 and a Y-shaped inflation tube 56. One end of the second inflation tube 54 and both ends of the Y-shaped inflation tube 56 are detachably fixed to the end of the rotary joint 43. The air inlet ends of the side airbag 62 and the bottom airbag 63 are fixed in the air delivery cavity 64. The gas entering the air delivery cavity 64 enters the side airbag 62 and the bottom airbag 63 through the air inlet ends, so that the airbags swell.

[0076] In further detail, depending on whether the affected limb is the left leg or the right leg, before actual use, the second inflation tube 54 and the Y-shaped inflation tube 56 are installed on the rotating joint 43 on the corresponding restriction member 61;

[0077] Specifically, the front three-way solenoid valve 52 can control the delivery pipe to be connected with the rear three-way solenoid valve 55 or the first inflation pipe 53. After the delivery pipe is connected with the rear three-way solenoid valve 55, the rear three-way solenoid valve 55 can control the delivery pipe to be connected with the second inflation pipe 54 or the Y-shaped inflation pipe 56, so that the air pump 51 can inflate the compression airbag 32, the side airbag 62 or the bottom airbag 63 respectively.

[0078] like Fig.10 As shown, a system for post-interventional limb care includes a central processing unit, an input end of the central processing unit is electrically connected to an output end of a data transmission module, an input end of the data transmission module is electrically connected to an output end of a monitoring module, the monitoring module includes a temperature sensor and a pressure sensor, an output end of the central processing unit is electrically connected to an input end of a control module, the control module includes an inflation and deflation assembly 50, and an output end of the central processing unit is connected to a user end signal;

[0079] Specifically, the temperature and pressure data can be monitored in real time through the sensor, and the pressure applied to the airbag can be adjusted through the inflation and deflation assembly 50 .

[0080] Specifically, when the device and system for post-interventional limb care are working / in use:

[0081] 1. Preparation stage: Place the buttocks board 10 and the leg restraint unit 60 flat on the bed, push the buttocks board 10 from the edge to the middle, and clamp the clamping frame 21 on the edge of the bed. Then, according to the patient's affected limb (left leg or right leg), install the second inflation tube 54 or the Y-shaped inflation tube 56 on the rotary joint 43 on the corresponding restraining member 61 (it is worth noting that if the other leg needs to be fixed, the inflation tube must be connected to the corresponding rotary joint 43 first, and then the side airbag 62 corresponding to the leg must be inflated. After the inflation is completed, the control tube 42 is rotated until the clamping column is engaged in the closing hole, and then the inflation tube is pulled out and installed on the rotary joint 43 corresponding to the affected limb);

[0082] 2. Fix the hip plate 10: Rotate the adjustment stud to move the clamping plate 22 upward and against the bottom of the bed, thereby fixing the position of the hip plate 10 to prevent displacement during braking;

[0083] 3. Adjust the position of the compression airbag 32: insert the push piece 31 into the slot 33 on the surface of the hip plate 10, and use the positioning screw hole on the top of the inner wall of the slot 33 and the mounting screw hole on one side of the push piece 31 to adjust the position of the push piece 31 up and down and left and right, and then adjust the position of the compression airbag 32 to adapt to the specific position of the patient. After adjustment, fix the push piece 31 in the slot 33 by the knob bolt.

[0084] 4. Connect the inflation and deflation system: control the delivery pipe to be connected with the first inflation pipe 53 or the rear three-way solenoid valve 55 through the front three-way solenoid valve 52. After the delivery pipe is connected with the rear three-way solenoid valve 55, control the delivery pipe to be connected with the second inflation pipe 54 or the Y-shaped inflation pipe 56 through the rear three-way solenoid valve 55 to inflate the compression airbag 32, the side airbag 62 or the bottom airbag 63 respectively.

[0085] 5. Inflation and compression: Start the air pump 51 to inflate the compression airbag 32 through the first inflation tube 53 to compress the puncture point;

[0086] When the side airbag 62 or the bottom airbag 63 is inflated, the control tube 42 is rotated to different angles to connect the air supply hole 46 with the synchronous air outlet holes 45 or the separate air outlet holes 47 at different positions, thereby inflating the side airbag 62 and the bottom airbag 63 to restrict the movement of the affected limb, and dynamically adjust the inflation volume of the side airbag 62 to apply dynamic pressure to the affected limb, thereby performing massage care on the affected limb;

[0087] Specifically, the rotation angle of the control tube 42 is adjusted through the rotating portion 44 and the clamping column, and its position is fixed, so as to dynamically adjust the inflation state of the airbag.

[0088] 6. Monitoring and control: The temperature and pressure data of the affected limb are monitored in real time through the temperature sensor and the pressure sensor, and the monitoring data is transmitted to the central processing unit through the data transmission module. The central processing unit adjusts the pressure applied by the airbag through the control module according to the monitoring data to maintain an appropriate compression effect;

[0089] 7. Observation and care: During the braking period, closely observe the patient's reaction and the condition of the affected limb, promptly detect and deal with adverse reactions, and adjust the compression force and position of the airbag in a timely manner according to the patient's specific situation and needs.

[0090] 8. Ending and cleaning: After use, gradually deflate the airbag and remove the device, then clean and disinfect the device for next use.

[0091] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
