Description

TECHNICAL FIELD

[0001] The present application relates to a defibrillation monitor, in particular to a detachable printer module of a defibrillation monitor. BACKGROUND

[0002] The existing defibrillation monitor generally has an integrated printer module and main body. When the printer module needs to be replaced or repaired, the main body needs to be disassembled, which is troublesome. The printing paper used in the current defibrillation monitor is generally divided into flat printing paper and roll paper. The former has a clear direction specificity and needs to be placed in the printer module according to the specified direction. If it is placed in the reverse direction, the printing operation cannot be normally performed. For the latter, no effective limiting structure is provided in the paper bin of the current defibrillation monitor. When the roll paper is installed, it is easy to be offset, and it is easy to shake during work, which can cause uneven tension on both sides of the paper (too much on one side and too little on the other side), and as the amount of roll paper increases, the roll paper becomes thin and can cause the roll paper to jump or deviate in the paper bin, resulting in paper jamming failure or printing interruption.

[0003] Therefore, in view of the above-mentioned technical problems, it is necessary to propose a new technical solution. SUMMARY

[0004] The present application aims to at least solve one of the problems in the prior art. A detachable printer module of a defibrillation monitor is proposed, which is independent of the main body of the defibrillation monitor and is easy to disassemble and assemble. Moreover, an elastic arm and a clamping column are provided in the containing bin, which can effectively ensure the stability of the movement of the paper roll in the containing bin and reduce the probability of printing interruption and paper jamming. The technical solution is as follows: A detachable printer module of a defibrillation monitor has a first direction, which includes a shell, a core, a cover and a paper feed roller. The core is arranged in the inner cavity of the shell, the cover is arranged on the shell, and the paper feed roller is arranged on the core and located on the side of the core. The axis direction of the paper feed roller is consistent with the first direction. The detachable printer module is detachably arranged on the main body of the defibrillation monitor. The inner cavity is provided with a containing bin for containing a paper roll. The containing bin is located on the side of the core where the paper feed roller is arranged. The side of the containing bin facing the core is provided with a bin opening. The bin opening is located below the paper feed roller. The containing bin is provided with two elastic arms arranged along the first direction. The opposite sides of the two elastic arms are respectively provided with clamping columns. The axis direction of the clamping column is consistent with the first direction.

[0005] The detachable printer module of the defibrillation monitor is a separate module independent of the main body of the defibrillation monitor, is convenient to detach and attach, does not need to disassemble the main body of the defibrillation monitor, and can reduce the operation difficulty of medical staff or maintenance personnel. Moreover, the accommodation cavity for accommodating the paper roll is provided, and the elastic arm and the clamping column are further provided in the accommodation cavity. The elastic arm and the clamping column can not only bidirectionally limit the paper roll, ensure the stability of movement of the paper roll in the accommodation cavity, and prevent the paper roll from deviating and jumping due to a small and thin remaining amount of the paper roll in the use process, and further prevent the printing from being interrupted or the paper jamming problem from occurring, but also can ensure the continuous and reliable printing process. Meanwhile, the elastic arm and the clamping column can support the printing paper to be loaded in the forward direction and the reverse direction, can greatly improve the operation convenience and the fault tolerance rate, and the elastic arm can better match the size of the paper roll, and avoid the axial deviation of the paper roll due to the size error of the paper roll.

[0006] In one of the embodiments, the accommodation cavity has two first cavity walls spaced apart along the first direction, and the first cavity walls are provided with V-shaped through holes with wide openings downward, so that wall portions of the first cavity walls below the V-shaped through holes form the elastic arms.

[0007] In one of the embodiments, the clamping column is arranged close to the upper end of the elastic arm, and the elastic arm is provided with a through hole group including at least one through hole. In this way, the elastic arm is more elastic, and the paper roll is more convenient to detach and attach.

[0008] In one of the embodiments, the through hole group includes a plurality of through holes, and the plurality of through holes are spaced apart around the axis of the clamping column.

[0009] In one of the embodiments, the upper end of the shell is provided with an opening corresponding to the accommodation cavity and communicating with the inner cavity, the opening extends above the paper feed roller, the cover body is arranged on the opening, and a paper outlet is formed between one end of the cover body corresponding to the movement core and the inner wall of the opening.

[0010] In one of the embodiments, the inner wall opposite to the cover body of the paper outlet is provided with a paper breaking structure. In this way, the paper breaking structure can conveniently tear the printing paper without adding extra mechanisms or parts.

[0011] In one of the embodiments, the paper breaking structure includes a plurality of paper breaking teeth distributed along the first direction.

[0012] In one of the embodiments, the paper breaking teeth are in the shape of a triangular pyramid, and the tapered portion thereof faces downward.

[0013] In one of the embodiments, the size of the paper breaking structure in the first direction is greater than the axial size of the paper roll. In one embodiment, the wall of the accommodating compartment is provided with mounting holes. When the detachable printer module is installed on the main body of the defibrillator, it is fixedly connected to the main body of the defibrillator via fasteners through the mounting holes. This design allows for simple and convenient installation and removal of the detachable printer module from the main body of the defibrillator by simply removing or installing the fasteners.

Detailed Implementation

[0016] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0017] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] This embodiment provides a detachable printer module for a defibrillator monitor. For easier description of the technical solution, the following definitions are used: Figure 1 The arrow shown indicates the first direction X. The detachable printer module includes a housing 1, a mechanism 2, a cover 3, and a paper feed roller 4. The mechanism 2 is disposed within the inner cavity 11 of the housing 1. The cover 3 is disposed within the housing 1, and the paper feed roller 4 is disposed within the cover 3 and located on the mechanism 2, with the axis of the paper feed roller 4 aligned with the first direction X. The detachable printer module is detachably mounted on the main body of the defibrillator monitor. The inner cavity 11 contains a receiving compartment 12 for accommodating a paper roll 7. The receiving compartment 12 is located on the side of the mechanism 2 where the paper feed roller 4 is located. The receiving compartment 12 has a compartment opening 121 facing the mechanism 2, located below the paper feed roller 4. The receiving compartment 12 has two elastic arms 122 spaced apart along the first direction X, and locking posts 123 are respectively provided on opposite sides of the two elastic arms 122, with the axis of the locking posts 123 aligned with the first direction X.

[0020] The aforementioned detachable printer module of the defibrillator monitor is an independent module separate from the main body of the defibrillator monitor, making it easy to assemble and disassemble without disassembling the main body of the defibrillator monitor, thus reducing the operational difficulty for medical staff or maintenance personnel. Furthermore, it is equipped with a receiving compartment 12 for accommodating the paper roll 7, and within the receiving compartment 12, there are also elastic arms 122 and locking posts 123. These not only provide bidirectional limiting for the paper roll 7, ensuring the stability of the paper roll 7's movement within the receiving compartment 12, preventing the paper roll 7 from shifting or jumping due to reduced margin or thinning during use, thus preventing printing interruptions or paper jams, but also ensure continuous and reliable printing. Simultaneously, it supports forward and reverse paper loading, significantly improving operational convenience and error tolerance, completely avoiding paper jams and printing failures caused by incorrect paper orientation, and reducing operational errors in clinical emergency scenarios. Moreover, the elastic arm 122 can better match the size of the paper roll 7, preventing axial displacement of the paper roll 7 due to size errors.

[0021] like Figures 1 to 5 As shown in the figure, a schematic embodiment is illustrated. The housing 1 includes a top plate 15, a first side plate 16 extending along the first direction X, and second side plates 17 and third side plates 18 spaced apart along the first direction X. The two ends of the first side plate 16 are respectively connected to the second side plate 17 and the third side plate 18. The first side plate 16, the second side plate 17, and the third side plate 18 are respectively connected to the top plate 15, thereby forming the inner cavity 11. The accommodating compartment 12 has two first compartment walls 124 spaced apart along the first direction X, a second compartment wall 126 extending along the first direction X and a vertical direction, and an arc-shaped compartment wall 127 extending along the first direction X, as shown below. Figure 5 As shown. The upper end of the first compartment wall 124 is connected to the top plate 15. Both ends of the second compartment wall 126 are connected to the two first compartment walls 124 respectively, and the upper end of the second compartment wall 126 is connected to the top plate 15. The second compartment wall 126 is parallel to and spaced apart from the first side plate 16. The arc-shaped compartment wall 127 is concave downward, one end of the arc-shaped compartment wall 127 is connected to the bottom end of the second compartment wall 126, and the other end of the arc-shaped compartment wall 127 faces the first side plate 16. The arc-shaped compartment wall 127 is connected to the bottom ends of the two first compartment walls 124 respectively.

[0022] The movement 2 is located between the first side plate 16 and the arc-shaped compartment wall 127, and the movement 2 is arranged along the first direction X, as shown below. Figure 4 and Figure 5As shown. The mechanism 2 is fixedly connected to the housing 1. Specifically, the mechanism 2 can be fixed to the housing 1 via a fixing bracket 5. The other end of the arc-shaped compartment wall 127 extends close to the mechanism 2. The mechanism 2 is provided with a paper roller groove 21 for mounting the paper feed roller 4 and a movable claw 22 for mounting the paper feed roller 4. A pressing arm 221 extends from the movable claw 22. Since the mechanism 2 is prior art, and its specific structure and installation method are not the focus of this application, they will not be described in detail in this application.

[0023] The upper end of the housing 1, i.e., the top plate 15, is provided with an opening 13 corresponding to the receiving compartment 12, which communicates with the inner cavity 11. The opening 13 extends toward the movement 2, such as... Figure 1 , Figures 3 to 5 As shown. The cover 3 is placed over the opening 13. Specifically, the end of the cover 3 facing away from the movement 2 can be rotatably connected to the top plate 15 via a pin structure; while the end of the cover 3 corresponding to the movement 2 can be directly attached to the upper end of the movement 2.

[0024] The lower side of the cover 3, near the end corresponding to the mechanism 2, is provided with a clamping structure 31 for clamping the paper feed roller 4. The clamping structure 31 extends to the end of the arc-shaped compartment wall 127 facing away from the second compartment wall 126, and a certain gap is formed between the clamping structure 31 and the end of the arc-shaped compartment wall 127 facing away from the second compartment wall 126, i.e., the compartment opening 121. The paper feed roller 4 is clamped to the side of the clamping structure 31 facing the mechanism 2. For example... Figure 6 As shown, bushings 42 are respectively provided at both ends of the roller shaft 41 of the paper feed roller 4. The bushings 42 are embedded in the slots on the clamping structure 31. The bushings 42 are restricted to not rotate relative to the clamping structure 31, while the roller shaft 41 can rotate relative to the bushings 42 within the bushings 42. One end of the roller shaft 41 is provided with a driven wheel 43 at the drive wheel corresponding to the mechanism 2. The roller shaft 41 and the driven wheel 43 are fixed together. When the cover 3 is placed over the opening 13, the paper feed roller 4 is located in the paper roller groove 21 of the mechanism 2 and is locked and limited by the movable claw 22. Figure 4 or Figure 5 As shown; simultaneously, the driven wheel 43 on the roller shaft 41 meshes with the drive wheel of the mechanism 2. Since the specific structure of the paper feeding roller 4, the way the paper feeding roller 4 is arranged on the cover 3, and the way the paper feeding roller 4 is arranged with the mechanism 2 can all be implemented using existing technology, and they are not the focus of this application, they will not be described in detail in this application.

[0025] A paper outlet 131 is formed between one end of the cover 3 corresponding to the mechanism 2 and the inner wall of the opening 13. For example... Figure 4 or Figure 5 As shown, the opening 13 extends above the paper feed roller 4, specifically located diagonally above the paper feed roller 4 facing the mechanism 2. The cover 3 has a notch at one end corresponding to the mechanism 2, so that when the cover 3 is placed over the opening 13, the cover 3 forms a paper outlet 131 extending along the first direction X between the notch and the inner wall of the opening 13. In a specific implementation, the paper roll 7 in the receiving compartment 12 passes sequentially through the compartment opening 121 and between the paper feed roller 4 and the mechanism 2, and then through the paper outlet 131 to the outside. When the detachable printer module is working, the drive wheel of the mechanism 2 drives the driven wheel 43 to rotate, which in turn drives the paper feed roller 4 to rotate, thereby moving the printing paper outwards, and the mechanism 2 prints on the printing paper.

[0026] like Figure 5 As shown in the figure, schematically illustrating one embodiment, each of the two first compartment walls 124 is provided with a downward-facing V-shaped through hole 1241, so that the portion of the first compartment wall 124 located below the V-shaped through hole 1241 forms the elastic arm 122. Further, the retaining post 123 is disposed near the upper end of the elastic arm 122, and the elastic arm 122 is provided with a group of through holes, the group of through holes including at least one through hole 1221. For example... Figure 5 In the schematically illustrated embodiment, the through-hole group includes two fan-shaped through holes 1221 spaced apart along the axis of the retaining post 123. This design makes the elastic arm 122 more flexible. When installing the paper roll 7, simply push the paper roll 7 into the receiving compartment 12, and the elastic arm 122 can adapt to the paper roll size by its own deformation, making it easier to install and remove the paper roll 7. Of course, the above are only some embodiments. In other embodiments, the number of through holes 1221 in the through-hole group is not limited to two; it can be one, three, or more. The shape and distribution of the through holes 1221 can also be set according to specific needs.

[0027] In one embodiment, the inner wall of the paper outlet 131 opposite to the cover 3 is provided with a paper-cutting structure 14. The dimension of the paper-cutting structure 14 in the first direction X is preferably larger than the axial dimension of the paper roll 7. For example... Figure 1 , Figures 3 to 5In the schematically illustrated embodiment, the paper-cutting structure 14 includes a plurality of paper-cutting teeth 141 distributed along the first direction X. Each paper-cutting tooth 141 is triangular pyramidal in shape, with its cone facing downwards. This design allows for convenient tearing of the printed paper without adding unnecessary mechanisms or parts. Furthermore, the smooth triangular pyramidal cutting edge allows for rapid and even tearing of the paper by applying tension at any angle to the cutting edge after the paper is output from the paper outlet 131, without any residue or breakage. No additional tools are required, and the single tearing operation time is ≤1 second, meeting the clinical need for defibrillator monitors to "rapidly acquire printed data." Of course, in other embodiments, the shape of the paper-cutting teeth 141 can also be other adaptable structures.

[0028] In a further embodiment, the wall of the accommodating compartment 12 is provided with mounting holes 125. When the detachable printer module is installed on the main body of the defibrillator monitor, the detachable printer module is fixedly connected to the main body of the defibrillator monitor through the mounting holes 125 by fasteners. For example... Figure 2 and Figure 5 As schematically shown, two fixing holes are spaced apart along the first direction X on the arc-shaped chamber wall 127. In specific implementation, the detachable printer module of this application can be embedded in a matching groove on the main body of the defibrillator monitor, and then locked and fixed to the main body of the defibrillator monitor through the mounting holes 125 using screws or other fasteners. With this design, during disassembly and assembly, only the fasteners need to be removed or removed to install the detachable printer module to the main body of the defibrillator monitor or to remove the detachable printer module from the main body of the defibrillator monitor, making the operation simple and convenient. Of course, the above is only a preferred embodiment. In specific implementation, the detachable printer module of this application only needs to be embedded in the main body of the defibrillator monitor to meet the usage requirements. Users can choose whether to use the fasteners for fixing according to specific needs. This application adopts an integrated module to simplify the overall assembly process of the defibrillator monitor. At the same time, the module can be produced, tested, and replaced separately, reducing the overall maintenance cost of the main unit and improving the reliability of the product.

[0029] In a further embodiment, a button 19 is also provided at the upper end of the housing 1, and the pressing arm 221 on the movable claw 22 extends below the button 19, as shown below. Figure 5 As shown. When the button 19 is pressed, the pressing arm 221 is driven to press down, thereby unlocking the movable claw 22 from limiting the paper feed roller 4. Furthermore, when the movable claw 22 rotates, it also lifts the end of the cover 3 corresponding to the mechanism 2, allowing the user to quickly open the cover 3. Since the button 19 and the movable claw 22 are existing technologies and are not the focus of this application, they will not be described in detail here.

[0030] Additionally, the detachable printer module also includes a circuit board 6, which is disposed in the inner cavity 11 and fixedly connected to the housing 1, such as... Figure 2 and Figure 4 As shown. The circuit board 6 is electrically connected to the mechanism 2. Since the circuit board 6 is prior art, and its specific structure and arrangement are not the focus of this application, it will not be described in detail here.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
