Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

The present inventors have found that cardiopulmonary resuscitation is often not effectively performed for persons not trained in cardiopulmonary resuscitation, i.e. depth, frequency at chest compressions is difficult to establish effective ventilation and blood circulation. To solve the above-mentioned problems, a person skilled in the art proposes a cardiopulmonary compression auxiliary device, which is worn on the wrist of an operator or on the body surface of a patient to sense parameters such as the compression depth and compression frequency of the operator, and outputs the parameters by voice or display, so as to be referred to by the operator. Therefore, the chest compression action can be conveniently adjusted by the operator through the parameters fed back by the cardiopulmonary compression auxiliary equipment, so as to realize more effective cardiopulmonary resuscitation.

For cardiopulmonary compression aids, the accuracy test currently employed is typically performed by manually simulating compression. However, the manual simulation of the pressing test mode requires a lot of manpower, which is inconvenient to realize efficient test. On the other hand, parameterized detection is difficult to realize by manual simulation pressing, and the detection result is affected by the subjective effect and has low accuracy.

In order to solve the above-mentioned problems, the present utility model provides a testing device, which includes a driver and a displacement detector, and the driver simulates an external chest compression action to achieve efficient detection. The displacement detector is used for detecting the actual action parameters of the cardiopulmonary compression auxiliary equipment, and comparing the parameters with the parameters sensed and output by the cardiopulmonary compression auxiliary equipment so as to judge whether the sensing result of the cardiopulmonary compression auxiliary equipment is accurate. The test device provided by the utility model will be described in detail below with reference to the detailed description and the accompanying drawings.

Referring to fig. 1 and 2, fig. 1 is an axial schematic view of a testing device according to an embodiment of the utility model, and fig. 2 is a front view of the testing device shown in fig. 1. An embodiment of the present utility model provides a testing device 10 including a driver 100 and a displacement detector 200. The driver 100 includes a placement tray 110 and a driving member (not shown) for driving the placement tray 110 to reciprocate, and the placement tray 110 is used for loading a cardiopulmonary compression aid. Since the cardiopulmonary compression auxiliary apparatus is mounted on the placement tray 110, the positions of the two are relatively stable, so that the actual motion of the placement tray 110, that is, the actual motion of the cardiopulmonary compression auxiliary apparatus, the displacement detector 200 can directly detect the motion of the cardiopulmonary compression auxiliary apparatus, and can indirectly obtain the motion of the cardiopulmonary compression auxiliary apparatus by detecting the motion of the placement tray 110. The specific actions of cardiopulmonary resuscitation can be simulated by driving the placement plate 110 to reciprocate by the driver 100. Thus, the test efficiency can be improved relative to manual simulation pressing.

The displacement detector 200 is used for detecting the displacement of the cardiopulmonary compression auxiliary device, and by comparing the parameter sensed by the cardiopulmonary compression auxiliary device with the actual parameter actually detected by the displacement detector 200, it can be determined whether the sensing of the cardiopulmonary compression auxiliary device is accurate. Compared with the manual subjective judgment, the accuracy of the detection result is improved.

Further, the cross-sectional area of the placement tray 110 is larger than the cross-sectional area of the cardiopulmonary compression auxiliary device in the direction perpendicular to the detection direction of the displacement detector 200, toward the side where the displacement detector 200 is located. In this way, it is possible to more facilitate the displacement detector 200 to detect the actual movement of the placement tray 110, i.e., to more facilitate the displacement detector 200 to detect the actual movement of the cardiopulmonary compression aid. The detection direction of the displacement detector is denoted by reference numeral K in fig. 1 and 2.

It will be appreciated that, since cardiopulmonary compression assistance devices are typically worn, for ease of handling and reduced physical energy consumption, the cardiopulmonary compression assistance devices are typically miniaturized and integrated. The tray 110 having a larger cross-sectional area in the detection direction is placed to facilitate detection. Meanwhile, the placement tray 110 is used for loading the cardiopulmonary compression auxiliary device, and the shape of the placement tray is simpler and more convenient to detect than that of the cardiopulmonary compression auxiliary device.

Referring to fig. 2, in one embodiment, the displacement detector 200 is positioned in the direction of movement of the puck 110. By the arrangement, the detection result can more directly reflect the movement of the heart-lung pressing auxiliary equipment, and the difficulty in data processing of the detection result of the displacement detector 200 is reduced.

In one embodiment, displacement detector 200 is used to emit a detection medium into the range of motion of the cardiopulmonary compression aid and receive the reflected detection medium, thereby detecting the actual displacement of the cardiopulmonary compression aid. In combination with the displacement detector 200 being located in the moving direction of the placement tray 110, the arrangement in this embodiment can further facilitate the transmission and reception of the detection medium, and facilitate the detection, i.e. the processing of the detection result.

The displacement detector 200 may be specifically a displacement detector 200 such as an infrared sensor, an ultrasonic sensor, or a laser sensor. When the displacement detector 200 is an infrared sensor, the detection medium is infrared; when the displacement detector 200 is an ultrasonic sensor, the detection medium is ultrasonic; when the displacement detector 200 is a laser sensor, the detection medium is a laser.

Referring again to FIG. 1, in one embodiment, the test apparatus 10 further includes a processor (not shown, described below) and a display 500. The test device 10 further includes a processor electrically connected to the driving member for adjusting the output motion of the driving member. Therefore, the stroke of the driving piece for driving the placement disc 110 to move and the frequency of the reciprocating movement can be adjusted through the processor, so that the accuracy of sensing results of the cardiopulmonary compression auxiliary equipment under different strokes and different frequencies can be tested.

It will be appreciated that the stroke and frequency of the reciprocating motion of the cardiopulmonary compression aid may be adjusted by inputting the stroke and frequency of the desired test to the processor.

The processor is electrically connected between the displacement detector 200 and the display 500 to parameterize the result detected by the displacement detector 200 and transmit the parameter to the display 500. The display 500 is used for displaying the detection result of the displacement detector 200, that is, the display 500 receives the parameter processed by the processor and outputs the parameter, so as to intuitively compare the display parameter of the cardiopulmonary compression auxiliary device with the actual parameter detected by the displacement detector 200.

Specifically, they may be electrically connected between the processor and the displacement detector 200 through the wire 700, and between the processor and the display 500 through the wire 700 for transmitting related information.

Referring to fig. 3, in one embodiment, the placement tray 110 includes a detection surface 111 and a fixing surface 112 disposed opposite to each other, the detection surface 111 faces the displacement detector 200, and the fixing surface 112 is used for loading the cardiopulmonary compression auxiliary device. Since the cardiopulmonary compression aid is provided on the placement tray 110 and is fixed in position relative to the placement tray 110, the placement tray 110 position is indicative of the movement of the cardiopulmonary compression aid. Loading cardiopulmonary compression aid on the side of the placement plate 110 facing away from the displacement detector 200, the surface of the side of the placement plate 110 for reference for detection by the displacement detector 200 is smoother, which facilitates detection of actual movement of the placement plate 110 by the displacement detector 200.

Referring to fig. 2 and 3, in one embodiment, the detection surface 111 is perpendicular to the movement direction of the tray 110. The direction of movement of the placement tray 110 is referred to by reference numeral M in fig. 2 and 3. Thus, when the detection medium reflected by the detection surface 111 is detected by the displacement detector 200, the entire displacement of the placement tray 110 can be reflected more intuitively. Thereby bringing the parameters detected by the displacement detector 200 closer to the actual movement of the cardiopulmonary compression aid. Thus, the accuracy in detecting the cardiopulmonary compression auxiliary device can be improved.

With continued reference to fig. 3, in one embodiment, the stationary surface 112 includes a plurality of mounting stations 112a, the plurality of mounting stations 112a being configured to mount cardiopulmonary compression assistance devices in a one-to-one correspondence. In this way, the single test process of the test device 10 can detect multiple cardiopulmonary compression auxiliary devices at the same time, so as to further improve the test efficiency of the test device 10.

Referring to fig. 3, in one embodiment, when the placement tray 110 is a circular disk-like structure, a plurality of mounting stations 112a may be disposed on the stationary surface 112 at intervals along the circumference of the placement tray 110. Of course, when the placing tray 110 is in other shapes, the plurality of mounting stations 112a may be uniformly arranged on the fixing surface 112 at intervals, so that the description thereof will not be repeated.

In one embodiment, the placement tray 110 includes a mounting structure (not shown, infra) that is removably attachable to the cardiopulmonary compression aid. In this way, the heart-lung pressing auxiliary equipment can be conveniently fixed on the placing plate 110 through the mounting structure, so that the heart-lung pressing auxiliary equipment can conveniently reciprocate along with the placing plate 110 to test the sensing accuracy of the heart-lung pressing auxiliary equipment. The mounting structure may be specifically disposed on the fixing surface 112.

Because the mounting structure is detachably connected with the cardiopulmonary compression auxiliary equipment, after the cardiopulmonary compression auxiliary equipment is tested, the cardiopulmonary compression auxiliary equipment after the testing is completed can be detached from the mounting structure so as to replace other cardiopulmonary compression auxiliary equipment to be detected.

In one embodiment, the number of the mounting structures may be plural, and the plural mounting structures may be disposed one by one corresponding to the positions of the mounting stations 112a, so as to fix the plural cardiopulmonary compression auxiliary apparatuses to the respective mounting stations 112a.

In some embodiments, the mounting structure may also be removably disposed on the placement tray 110. In this embodiment, the mounting structure may include a plurality of mounting portions (not shown, the same applies below), and the distribution of the plurality of mounting portions corresponds to the plurality of mounting stations 112a. When detecting a certain batch of cardiopulmonary compression auxiliary equipment, another batch of cardiopulmonary compression auxiliary equipment can be simultaneously installed on another installation structure. Therefore, when the cardiopulmonary compression auxiliary equipment borne by one mounting structure is tested, the other mounting structure bearing a plurality of cardiopulmonary compression auxiliary equipment can be quickly replaced, so that the test of the cardiopulmonary compression auxiliary equipment is further improved.

Of course, no additional mounting structure may be provided on the support plate. At this time, the cardiopulmonary compression auxiliary apparatus may be fixed to the fixing surface 112 of the placement tray 110 by means of an adhesive tape or the like.

Referring again to fig. 1 and 2, in one embodiment, the testing apparatus 10 includes a stand assembly 300 and a base 400, wherein the stand assembly 300 is disposed on the base 400.

Of course, in some embodiments, the base 400 may not be provided, and the bracket assembly 300 may be directly provided on the ground or other supporting structure.

The carriage assembly 300 includes a first carriage 310 carrying the driver 100 and a second carriage 320 carrying the displacement detector 200, the first carriage 310 being spaced from the second carriage 320 and reducing the transmission of motion between the first and second carriages 310, 320. Thus, the influence of vibration possibly generated by the driving motion of the driver 100 on the displacement detector 200 can be reduced, and the detection result of the displacement detector 200 can be more accurate.

With continued reference to fig. 1 and 2, in one embodiment, the test apparatus 10 further includes a shock absorbing member (not shown, described below). The bracket assembly 300 is disposed on the working surface, and the damping member is disposed between the first bracket 310 and the working surface. In this way, the vibration motion, which may be generated by the driving motion of the driver 100, can be reduced by the shock absorbing member, and transferred to the second bracket 320 through the working surface. In other words, the transmission of the motion between the first bracket 310 and the second bracket 320 can be reduced by the shock absorbing member, so that the detection result of the displacement detector 200 on the displacement second bracket 320 is more accurate.

The working surface may be a surface of the base 400 for supporting the first bracket 310 and the second bracket 320, or the working surface may be a surface of the ground or the like for supporting the first bracket 310 and the second bracket 320.

In some embodiments, a shock absorber may also be provided between the second bracket 320 and the work surface. Thereby, the transmission of the vibration motion from the first bracket 310 to the second bracket 320 can be reduced by the shock absorbing member as well, thereby improving the accuracy of the detection result of the displacement detector 200.

Of course, in some embodiments, the damping member may be disposed between the first support 310 and the working surface, and between the second support 320 and the working surface, so as to reduce transmission of vibration between the first support 310 and the second support 320, thereby improving accuracy of detection result of the displacement detector 200 located on the second support 320.

The damping member may be a damping spring, a damping cushion or other damping structure.

In one embodiment, the test device 10 further includes a top cover 600, the top cover 600 being disposed on the rack assembly 300. The upper cover 600 is hollow, the driving element and the processor are both arranged in the upper cover 600, and the display 500 is embedded in the upper cover 600 for displaying related information.

Referring to fig. 2, in one embodiment, the first bracket 310 includes a top plate 311 and a support plate 312, and the support plate 312 is connected to the top plate 311 and is supported between the top plate 311 and the base 400. The upper cover 600 and the displacement detector 200 are respectively located at two opposite sides of the top plate 311, i.e. the processor, the display screen, etc. are arranged in the upper cover 600 and located at one side of the top plate 311 away from the displacement detector 200. By such arrangement, the structure in the detection range of the displacement detector 200 can be relatively reduced, so that the interference in the detection process of the displacement detector 200 can be simplified and reduced.

In one embodiment, the driving member may be a motor (not shown, the same applies below). In this embodiment, the driver 100 may further include a transmission structure (not shown, hereinafter, the same applies) connected between the driving member and the placement tray 110. That is, in the present embodiment, the rotational movement output from the motor can be converted into the linear movement of the placement tray 110 by the transmission structure. The processor may be electrically connected to the motor, and the processor may control the direction in which the placement tray 110 reciprocates by controlling the steering of the motor.

For example, the transmission structure may be a rack and pinion transmission structure, i.e. a motor is connected to a gear to drive the gear to rotate. And the rack may be connected between the gear and the placing tray 110. When the gear rotates, the placing tray 110 can be driven to linearly move by the rack. It should be noted that, for convenience of connection, the transmission structure may be provided to include a transmission rod, and the rack is provided on an outer circumferential surface of the transmission rod. Of course, the placing tray 110 can be driven to reciprocate by a driving member through other mechanical transmission modes. For example, a transmission mode of matching a screw with a nut and a transmission mode of matching a worm wheel with a worm can be adopted.

Of course, the driving member is not limited to a motor. For example, in some embodiments, the drive member may also be a linear drive 100 such as a pneumatic cylinder, hydraulic cylinder, electric push rod, or the like.

In one embodiment, the top plate 311 is provided with a via, and the transmission rod is connected between the placing plate 110 and the driving member through the via. It will be appreciated that since the displacement detector 200 is used to detect the movement of the placing tray 110, the placing tray 110 needs to be provided on the side of the top plate 311 close to the displacement detector 200. Therefore, by providing the through hole through which the transmission rod passes, the placing tray 110 can be conveniently driven to reciprocate. The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
