[0041] Embodiment:

[0042] The embodiment of the present application provides a medical device, which comprises a device body and a printer module, the printer module is installed on the device body and is used for printing an inspection report of the medical device. The medical device can be a fetal monitor, an electrocardiograph, a defibrillator and an ultrasonic diagnostic instrument.

[0043] Please refer to Figure 1 , Figure 2 and Figure 6 , the printer module comprises an upper cover 1, a base 2, a traction assembly 4, a printing assembly 5 and a locking structure. The bottom of the upper cover 1 is provided with an accommodating cavity 11; one end of the base 2 is installed on the bottom of the upper cover 1 through a connecting shaft 3 and can slide along the radial direction of the connecting shaft 3 and rotate around the connecting shaft 3 relative to the upper cover 1; the traction assembly 4 is fixed to the base 2; the printing assembly 5 is fixed in the accommodating cavity 11; the locking structure comprises a locking assembly 6 and a trigger assembly 7, the locking assembly 6 is arranged on the printing assembly 5, and the trigger assembly 7 is arranged on the base 2 and can move between a locking position and an unlocking position.

[0044] When the trigger assembly 7 is located at the locking position, the printing assembly 5 is fixed with the traction assembly 4 through the locking assembly 6, so that the upper cover 1 and the base 2 are fixed with each other, thereby the base 2 cannot slide and rotate relative to the upper cover 1, and the normal work of the printer module is ensured; when the trigger assembly 7 is located at the unlocking position, the printing assembly 5 is separated from the traction assembly 4 through the cooperation of the locking assembly 6, so that the upper cover 1 and the base 2 are separated from each other, thereby the base 2 can slide and rotate relative to the upper cover 1, and the inside of the printer module is exposed, so that the paper roll 9 can be taken out and placed in the printer module. Since the trigger assembly 7 is actuated to the locking position or the unlocking position by being rotated, the force is convenient to exert, and the actuation of the trigger assembly 7 does not cause pain, thereby the unlocking operation experience of the printer module is good.

[0045] It should be noted that, in the present application, when the trigger assembly 7 is actuated to the unlocking position, the base 2 needs to slide relative to the upper cover 1 by a certain distance before being rotated, and the base 2 is rotated downward relative to the upper cover 1. In actual application scenarios, the gap between the upper cover 1 and the top of the device body is generally small, and the downward rotation of the base 2 relative to the upper cover 1 can avoid taking out and placing the paper roll 9 by actuating the upper cover 1, thereby improving the adaptation range of the printer module.

[0046] Please refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the side of the printing assembly 5 away from the connecting shaft 3 is provided with a containing groove 521 for accommodating the traction assembly 4, the traction assembly 4 includes a fixing seat 41 and a roller 42, the fixing seat 41 is fixed to the base 2, the roller 42 is rotatably assembled to the fixing seat 41, and the locking assembly 6 is used for limiting the roller 42 in the containing groove 521. Specifically, the connecting shaft 3 and the traction assembly 4 are located at two ends of the base 2 respectively, the locking assembly 6 is rotatably assembled to the printing assembly 5, the locking assembly 6 can be rotated relative to the printing assembly 5 to change the size of the slot of the containing groove 521, thereby limiting the roller 42 in the containing groove 521 or allowing the roller 42 to be separated from the containing groove 521, for example: when the locking assembly 6 is rotated clockwise by a predetermined angle, the slot width of the containing groove 521 is smaller than the diameter of the roller 42, at this time the locking assembly 6 clamps the roller 42 in the containing groove 521; when the locking assembly 6 is rotated counterclockwise by a predetermined angle, the slot width of the containing groove 521 is greater than the diameter of the roller 42, at this time the roller 42 can be separated from the containing groove 521 along the sliding direction of the base 2.

[0047] It should be noted that, when the locking assembly 6 limits the roller 42 in the containing groove 521, the roller 42 can continue to rotate, thereby ensuring the normal implementation of the function of the traction assembly 4.

[0048] Please refer to Figure 2 , Figure 3 and Figure 4Further, the locking assembly 6 comprises a first rotating shaft 61, a limiting member 62, an abutting member 63 and a first restoring member.

Wherein, the first rotating shaft 61 is parallel to the roller 42, and the height of the first rotating shaft 61 relative to the base 2 is higher than the height of the roller 42 relative to the base 2, which is conducive to the first rotating shaft 61 driving the limiting member 62 to move in the accommodating groove 521. The limiting member 62 is partially located between the opposite two side walls of the accommodating groove 521 which are arranged adjacent to the slot of the accommodating groove 521, so that the limiting member 62 can change the slot of the accommodating groove 521 by following the rotation of the first rotating shaft 61, and the slot width of the accommodating groove 521 becomes larger when the limiting member 62 rotates clockwise, and becomes smaller when the limiting member 62 rotates counterclockwise.

One end of the first rotating shaft 61 is fixed with a connecting piece 64, and the abutting member 63 is fixed on the end of the connecting piece 64 away from the first rotating shaft 61, that is, the abutting member 63 is connected with the first rotating shaft 61 through the connecting piece 64, so that the abutting member 63 can be vertically arranged, which is conducive to the contact between the triggering assembly 7 and the abutting member 63.

[0051] In some embodiments, the trigger assembly 7 is arranged on the abutting member 63 at a side close to the connecting shaft 3, and the side of the abutting member 63 close to the connecting shaft 3 is provided with an abutting groove. When the trigger assembly 7 is in the locking position, the trigger assembly 7 abuts against the groove wall of the abutting groove, and the abutting force applied by the trigger assembly 7 to the abutting member 63 is perpendicular to the first rotating shaft 61, so that the abutting member 63 cannot rotate due to the abutting of the trigger assembly 7; when the trigger assembly 7 is in the unlocking position, the trigger assembly 7 abuts against the groove wall of the abutting groove, and the abutting force applied by the trigger assembly 7 to the abutting member 63 is not intersected with the first rotating shaft 61, so that the abutting member 63 can rotate due to the abutting of the trigger assembly 7, so that the roller 42 can be separated from the accommodating groove 521.

[0052] Please refer to Figure 2 , Figure 3 and Figure 5 In some embodiments, the trigger assembly 7 comprises a second rotating shaft 71, a trigger member 72 and a second restoring member 73.

The connecting seat 74 is rotated to make the trigger 72 abut against the abutting piece 63 to rotate by a certain angle, the limiting piece 62 rotates by a certain angle following the first rotating shaft 61, at this time the roller 42 can be separated from the containing groove 521, so that the base 2 slides a certain distance to the right relative to the upper cover 1, at this time the connecting shaft 3 slides to the left end of the sliding groove 22, and then the base 2 rotates downward around the connecting shaft 3 as the rotating shaft, the internal space of the printer module is exposed, and the paper roll 9 can be taken out and placed, and after the taking out and placing of the paper roll 9 are completed, the sequence is reversed to make the limiting piece 62 limit the roller 42 in the containing groove 521.

[0056] Please refer to Figure 2 , Figure 4 and Figure 5 Further, two connecting shafts 3 are arranged between each side wall and the upper cover 1, and each side wall is provided with two sliding grooves 22 and a guide groove 23 corresponding to the two connecting shafts 3, and the base 2 is also provided with a guide groove 23, which is communicated with one of the two sliding grooves 22, so as to form the rotation of one of the two connecting shafts 3 in the guide groove 23 around the other connecting shaft 3. Specifically, the guide groove 23 is communicated with the right one of the two sliding grooves 22, when the base 2 moves a certain distance relative to the upper cover 1, it rotates downward around the connecting shaft 3 in the left sliding groove 22 as the rotating shaft, and the other connecting shaft 3 slides in the guide groove 23, so that the rotation of the base 2 can be guided through the guide groove 23, and the rotation of the base 2 is more stable.

The fixing frame 51 is fixed in the accommodating cavity 11, and the fixing frame 51 and the upper cover 1 define a paper compartment. The paper compartment is provided with a second rotating shaft 71 for mounting the paper roll 9. Since the paper compartment is located in the upper cover 1, the space in the accommodating cavity 11 can be reasonably utilized, the volume of the upper cover 1 is reduced, and thus the volume of the printer module is reduced. The printing head 52 is fixed to the fixing frame 51 and located in the accommodating cavity 11.

The connecting seat 74 is counterclockwise rotated to make the trigger piece 72 cooperate with the abutting piece 63, so that the limiting piece 62 is rotated clockwise to increase the width of the slot of the accommodating groove 521. Then the base 2 is slid to the left for a certain distance until it cannot be slid. At this time, the roller 42 enters the accommodating groove 521, the connecting seat 74 is released, so that the roller 42 is limited in the accommodating groove 521 by the limiting piece 62. The base 2 and the upper cover 1 are fixed to each other through the connection between the printing assembly 5 and the traction assembly 4, so as to ensure the normal use of the printer module.
