Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a heart compression device. Background Art

[0002] Cardiac compression is a first aid measure. When a patient suffers from sudden cardiac arrest or other critical conditions, the doctor will use cardiac compression first aid techniques to press the patient's heart in order to save the patient's life in order to wake up the patient's heart.

[0003] Heart compression consumes a lot of doctors' physical strength, and often requires multiple doctors to take turns to manually perform heart compression. In the case of a major accident, the doctor-patient ratio is often seriously unbalanced, and doctors are short of manpower, making it difficult to provide emergency treatment for multiple people. Therefore, there is an urgent need for a heart compression device to achieve heart compression to reduce the workload of medical staff. Utility Model Content

[0010] Furthermore, the rotating structure includes a rotating rod and an arc-shaped rotating channel, the rotating channel is arranged in the shell, the rotating rod is connected to the annular track, and the rotating rod extends from the shell through the rotating channel to the outside of the shell.

[0011] Furthermore, the rotating rod is connected to a limiting structure.

[0012] Furthermore, the limiting structure includes a U-shaped sleeve and a plurality of limiting holes distributed around the rotating channel, one end of the U-shaped sleeve is sleeved outside the rotating rod and is loosely matched with the rotating rod, and the other end of the U-shaped sleeve can be inserted into the limiting hole.

[0013] Furthermore, the annular track is in the shape of a circular ring, and the axial direction of the rotation axis of the rotating structure rotating the annular track does not coincide with the axial direction of the central axis of the annular track.

[0014] As another design, the annular track is elliptical, and the axial direction of the rotation axis of the rotating structure rotating the annular track coincides with the axial direction of the central axis of the annular track.

[0031] After the support 1 is installed at the bedside, the pressing structure 9 is aligned with the patient's heart. Under the action of the rotating power structure, the rotating rod 4 rotates, driving the first slide 7 to rotate on the circular track 3, and the second slide 8 moves on the linear track 5 through the transmission of the transmission rod 6, so that the pressing structure 9 moves up and down to achieve compression of the heart, thereby reducing the workload of medical staff.

[0032] A pressing amplitude control structure is provided in the housing 2, and the pressing amplitude control structure is connected to the pressing control structure.

[0033] Under the action of the pressing amplitude control structure, the pressing amplitude is adjustable and can be suitable for people of different ages and different physical conditions.

[0034] For thin people, after the bracket 1 is installed, the lowest point of compression needs to be lowered to achieve cardiac compression, while for strong people, the opposite is true.

[0035] The pressing amplitude control structure is an adjustment structure, which is connected to the annular track 3 . The adjustment structure adjusts the annular track 3 to adjust the shortest distance between the annular track 3 and a linear track 5 fixed in the housing 2 .

[0036] By adjusting the shortest distance between the annular track 3 and the linear track 5 fixed in the housing 2 , the pressing amplitude can be controlled.

[0037] A track plate 10 is disposed in the housing 2 , and the annular track 3 is disposed on the track plate 10 .

[0038] The rotating power structure is a first rotating motor 11 . The first rotating motor 11 is fixed in the housing 2 , and a rotating shaft of the first rotating motor 11 is connected to the rotating rod 4 .

[0039] The rotating shaft of the first rotating motor 11 passes through the track plate 10 .

[0040] The rotating rod 4 is provided with a strip-shaped hole 12 , and the first sliding member 7 is provided with a first connecting member 13 , and the first connecting member 13 is arranged in the strip-shaped hole 12 .

[0047] The rotating structure includes a rotating rod 16 and an arc-shaped rotating channel 17 . The rotating channel 17 is disposed in the housing 2 . The rotating rod 16 is connected to the annular track 3 . The rotating rod 16 extends from the housing 2 to the outside of the housing 2 through the rotating channel 17 .

One end of the U-shaped sleeve 18 is sleeved outside the rotating rod 16 and has a clearance fit with the rotating rod 16 . The other end of the U-shaped sleeve 18 can be inserted into the limiting hole 19 .

[0050] The axis of the rotating shaft of the rotating rod 4 coincides with the axis of the rotating shaft of the rotating structure rotating annular track 3. This is because the track plate 10 or the annular track 3 is fixed by the rotating shaft of the first rotating motor 11 and the rotating rod 16 after limiting.

[0051] Embodiment 4:

[0052] like Figure 6 As shown, the fourth embodiment has all the features of the second embodiment, except that:

[0055] At this time, it is not necessary to emphasize that the axial direction of the rotating shaft of the rotating rod 4 coincides with the axial direction of the rotating shaft of the rotating structure rotating annular track 3 .

[0056] Embodiment five:

[0057] like Figure 6 As shown, the fifth embodiment has all the features of the second embodiment, except that:

[0058] The annular track 3 is in the shape of a circular ring, and the axial direction of the rotation axis of the rotating structure rotating the annular track 3 does not coincide with the axial direction of the central axis of the annular track 3 .

[0064] The adjustment structure is a moving structure, and the moving structure moves the position of the annular track 3 .

[0065] The moving mechanism is a linear motor 21 .

[0066] The track plate 10 is provided with a linear hole 23, and the rotating shaft of the first rotating motor 11 passes through the linear hole 23. The extending direction of the linear hole 23 is consistent with the moving direction of the linear motor 21.

[0067] Alternatively, the linear motor 21 and the first rotary motor 11 are respectively disposed on the front and rear sides of the track plate 10 .

[0068] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
