Detailed Description

Hereinafter, only certain exemplary embodiments are briefly described. As will be recognized by those of skill in the pertinent art, the described embodiments may be modified in various different ways without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive.

The present disclosure first provides a position adjustment apparatus 10 for adjusting the position of a detection device. The position adjustment device 10 is described in detail below with reference to fig. 1 to 7.

FIG. 1 illustrates a schematic perspective view of a position adjustment device according to one embodiment of the present disclosure; FIG. 2 illustrates a schematic view of the position adjustment device 10 with the equipment box assembly 300 removed, according to one embodiment of the present disclosure; FIG. 3 shows an exploded schematic view of a part of the structure of the position adjustment device 10 according to one embodiment of the present disclosure; fig. 4 shows a schematic view of a rear view of the position adjustment device 10 according to one embodiment of the present disclosure. As shown in fig. 1 and 2, a position adjusting apparatus 10 for adjusting a position of a detection device includes: bracket assembly 100, slide assembly 200, and equipment cabinet assembly 300.

The bracket assembly 100 has a first end and a second end in a first direction, the first end being provided with a sliding window 101 extending along a second direction, wherein the second direction is different from the first direction. In some embodiments, the second direction may be orthogonal to the first direction. As shown in fig. 1, the first direction may be a Z direction shown in the drawing, or an up-down direction; the second direction is the X direction shown in the figure, or the front-rear direction. The sliding window 101 may have a rectangular shape with a longest edge extending in the X direction. In other embodiments, the second direction may be approximately perpendicular to the first direction, or both may be disposed at an angle, such as an included angle greater than 75 °, greater than 80 °, etc. The second end of the subsequent bracket assembly 100 may be fixedly disposed on a base (e.g., a bed).

The slider assembly 200 may include a slider 210 and a telescoping member 220. The slider 210 is provided at the sliding window 101 and is configured to be capable of bidirectional sliding along the extending direction of the sliding window 101. One end of the telescopic member 220 is fixedly connected to one end of the sliding window 101 in the second direction, the other end thereof is connected to the sliding member 210, and the telescopic member 220 is used for shielding the sliding window 101. It should be noted that the number of the telescopic members 220 may be two, and the telescopic members are respectively disposed at two sides of the sliding member 210, so as to cover the sliding window 101 at two sides of the sliding member 210. To facilitate the illustration of the sliding window 101, the telescoping member 220 on one side of the sliding member 210 is hidden in fig. 2. Fig. 3 illustrates an exploded view of a portion of the structure of the position adjustment device 10, wherein the bracket assembly 100 is hidden, according to one embodiment of the present disclosure. As shown in fig. 3, in some embodiments, the telescoping member 220 comprises a folding telescoping member 220, the folding telescoping member 220 having a plurality of folds along the second direction, for example, there may be 5, 6, 8, or even more folds. As the telescoping member 220 expands or contracts, the plurality of folds expand or collapse, and the extension length of the telescoping member 220 will change accordingly. The folder type extension 220 may be made of plastic or rubber, etc., and have a certain ductility and toughness at the same time, and the folder type extension 220 may be used to shield the sliding window from direct exposure of the sliding window 101. The end of the folder-type expansion member 220 facing away from the slider 210 is fixedly coupled to the rim of the sliding window 101 by means of a screw, and the end facing the slider 210 is coupled to the slider 210 by means of a screw. As shown in fig. 3, the opposite ends of the folder type telescopic member 220 and the relative positions of the sliding member 210 and the frame of the sliding window 101 are provided with a plurality of screw holes so as to facilitate the interconnection between the above-mentioned elements. Although in the present embodiment, the telescoping member 220 is shown as a folding telescoping member 220, in other embodiments, the telescoping member 220 may also be a telescoping member such as a telescoping rod, telescoping spring, or the like, which may replace the folding telescoping member 220 described above, and which may provide some holding force to the sliding member 210 when the sliding member 210 is moved to a particular position of the sliding window 101.

The inside of the equipment cabinet assembly 300 is for mounting the inspection equipment, and the outside of the equipment cabinet assembly 300 is fixedly connected to the slider 210 and configured to be capable of bi-directional movement in the second direction using the slider assembly 200. As shown in fig. 3, the outer wall of the equipment cabinet assembly 300 may be fixedly coupled to the end surface of the slider 210 protruding from the sliding window 101 by screws, thereby achieving movement of the equipment cabinet assembly 300 together with the slider 210.

In the embodiment of the present disclosure, by providing the sliding window 101 along the second direction on the bracket assembly 100 and providing the sliding assembly 200 capable of moving the equipment box assembly 300 along the sliding window 101, the equipment box assembly 300 can be slid along the second direction by the user manually pushing the equipment box assembly 300, thereby achieving the position adjustment of the detection apparatus in the second direction.

As shown in fig. 2 and 4 (in fig. 4, the second side wall 120 of the bracket assembly 100 is hidden in order to show the internal structure of the bracket assembly 100), the bracket assembly 100 includes: a housing. The housing interior forms a receiving cavity, one end of the receiving cavity in a first direction (i.e., the same end as the first end of the bracket assembly 100) communicates with the sliding window 101, and wherein at least a portion of the slider 210 is disposed in the receiving cavity. The housing has a first side wall 110 and a second side wall 120 disposed opposite to each other in a third direction, wherein the third direction is orthogonal to the second direction, and the sliding window 101 is disposed on the first side wall 110. The third direction may be orthogonal to both the first direction and the second direction. The first and second sidewalls 110 and 120 may each be arc-shaped such that the receiving chamber is formed as a chamber having an approximately arc-shaped cross section. And the second side wall 120 has a larger vertical dimension than the first side wall 110 such that both ends of the second side wall 120 in the first direction extend beyond both ends of the first side wall 110 in the first direction, thereby allowing the end face of the housing at the first end to extend in a vertical plane (i.e., in the XOZ plane shown in the drawing). In addition, the housing may also have a front wall 130 and a rear wall for closing the receiving cavity.

This arrangement may allow the equipment cabinet assembly 300 to be located entirely on one side of the rack assembly 100 (i.e., outside of the first sidewall 110), thus facilitating positional adjustment of the equipment cabinet assembly 300. When the position adjustment device 10 is fixedly arranged on a base (for example, a bed body) later, since only one side of the equipment box assembly 300 is provided with the bracket assembly 100, a person or patient to be detected can enter the lower part of the equipment box assembly 300 from the other side of the equipment box assembly 300, and thus, compared with the situation that the bracket assemblies 100 are arranged on both sides of the equipment box assembly 300, the detection of the person to be detected is more convenient.

In some embodiments, at least one first guide rail extending along the second direction is disposed inside the housing, and at least one first sliding groove is disposed at a corresponding position of the sliding member 210, and the first guide rail and the corresponding first sliding groove cooperate to realize sliding of the sliding member 210. As shown in fig. 4, the number of first guide rails is two, namely, a first guide rail 102a and a first guide rail 102b, and the first guide rail 102a and the first guide rail 102b are provided at positions near the upper edge and the lower edge of the sliding window 101, respectively. In the present embodiment, by providing the first guide rail and the first slide groove, the sliding of the slider 210 in the second direction can be ensured, avoiding the slider 210 from being separated from the sliding window 101.

As shown in fig. 3, the slider 210 includes: a first portion 211 and a second portion 212. The first portion 211 is disposed to extend in a first direction and is disposed within the receiving cavity. The second portion 212 has one end connected to the first portion 211 and the other end protruding from the sliding window 101 in a third direction (Y direction shown in the drawing, hereinafter also referred to as left-right direction) for connecting the equipment box assembly 300. The shape of the first portion 211 may be adapted to the sectional shape of the receiving cavity, and when the first portion 211 is positioned in the receiving cavity, both sides thereof in the third direction are respectively fitted to the inner sides of the first and second sidewalls 110 and 120, so that the slider 210 may be stably moved within the receiving cavity. The second portion 212 is approximately rectangular and may have an approximately rectangular end surface extending from the sliding window 101, and a screw hole is provided in the end surface to facilitate subsequent threaded connection with the equipment box assembly 300. The first sliding groove provided on the slider 210 may include a first sliding groove 213a and a first sliding groove 213b, the first sliding groove 213a being provided on the top surface of the second portion 212 to correspond to the first rail 102a, and the first sliding groove 213b being provided on the bottom surface of the second portion 212 to correspond to the first rail 102 b.

The magnetocardiography 1 is typically placed in an independent room of 10-20 square meters. The person to be detected does not need to make any preparation, and only needs to lie on the magnetocardiograph 1 for 1-10 minutes in the scanning process. The detection personnel can independently complete the detection flow in a short time, and the detection result is automatically recorded in the corresponding storage equipment. The magnetocardiogram generated by the magnetocardiogram instrument 1 can be used for diagnosing whether the patient has myocardial ischemia, microangiopathy, ventricular hypertrophy and the like. The magnetocardiograph 1 has sufficiently high sensitivity, and can accurately find the trace of myocardial apoptosis or necrosis caused by myocardial ischemia in the past.
