Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an electrocardiograph. Background Art

[0002] The electrocardiograph can automatically record the bioelectric signals (electrocardiogram signals) generated by the myocardial excitation during cardiac activity. It is a medical electronic instrument commonly used in clinical diagnosis and scientific research. Before the heart beats, the myocardium is first excited, and a weak electric current is generated during the excitement process. This current is transmitted to various parts of the human body through human tissue. Due to the different tissues of various parts of the body and the different distances between each part and the heart, different potential changes are shown in different parts of the human body surface. The relationship between the surface potential and time generated by the electrical activity in the human heart is called an electrocardiogram. An electrocardiograph is an instrument that records these physiological electrical signals. Domestically, they are divided into single-channel, three-channel, six-channel and twelve-channel electrocardiographs according to the number of synchronous output channels of the recorder.

[0003] When the electrocardiogram records the heartbeat, the heartbeat index is reflected by the broken line appearing on the electrocardiogram paper. In order to facilitate the replacement of electrocardiogram paper, the current electrocardiogram machine's paper bin is made into a drawer type. When the paper needs to be replaced, the paper bin structure can be pulled out of the electrocardiogram machine. This operation is convenient and quick. However, there is a blockage in the pulling process, and it cannot be pulled out smoothly, and the operation is time-consuming and laborious.

[0004] Therefore, it is particularly important to improve the existing electrocardiograph and design a new electrocardiograph to solve the above technical defects and improve the practicability of the overall electrocardiograph. Utility Model Content

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Example: See Figure 1-Figure 4 , the utility model provides a technical solution:

[0022] An electrocardiograph comprises an electrocardiograph 1, a protective cover 101 is installed on the outside of the electrocardiograph 1, a display 2 is installed on the top of the electrocardiograph 1, a cover 3 is installed on the left end of the top of the electrocardiograph 1, a paper bin 4 is opened below the cover 3, and a self-locking component 5 is installed between the cover 3 and the electrocardiograph 1;

[0023] The self-locking component 5 is used for quick opening and closing between the cover 3 and the electrocardiograph 1 .

[0024] For further information, see Figure 2 , Figure 3 and Figure 4In this embodiment, the self-locking component 5 includes a T-shaped frame 501, a pressing block 502, a special-shaped groove 503, a special-shaped block 504, a fixed block 505, a spring 506, a card roller 507 and a collision block 508. The T-shaped frame 501 is installed inside the electrocardiograph 1, the pressing block 502 is installed inside the T-shaped frame 501, the special-shaped groove 503 is opened inside the pressing block 502, the special-shaped block 504 is installed inside the special-shaped groove 503, the fixed block 505 is installed at the bottom end of the inner side of the T-shaped frame 501, the spring 506 is installed between the pressing block 502 and the fixed block 505, and the card roller 507 is installed outside the fixed block 505. The impact block 508 is installed at the bottom of the cover 3. When the electrocardiogram paper needs to be replaced, the cover 3 is pressed so that the impact block 508 squeezes the pressure block 502, thereby driving the spring 506 to contract, so that the card roller 507 slides inside the special-shaped groove 503, so that the card roller 507 is disengaged from the recess of the special-shaped block 504, so that the contraction force of the spring 506 is released, so that the top end of the pressure block 502 pops out of the T-shaped frame 501, thereby releasing the fixation of the impact block 508, so that the cover 3 and the paper bin 4 are separated, making it more convenient to replace the electrocardiogram paper.

[0025] Among them, see Figure 2 , Figure 3 and Figure 4 In this embodiment, one end of the card roller 507 is connected to the fixed block 505 in a rotating manner, and the end of the card roller 507 away from the fixed block 505 is connected to the special-shaped groove 503 in a sliding manner. By swinging one end of the card roller 507 inside the fixed block 505, the other end of the card roller 507 can slide smoothly inside the special-shaped groove 503.

[0026] Second, see Figure 2 , Figure 3 and Figure 4 In this embodiment, the top of the pressing block 502 is designed with an inclined structure, and a connecting seat 509 is symmetrically installed on the top of the pressing block 502. A clamping strip 510 is installed inside the connecting seat 509. When the pressing block 502 is pressed into the inside of the T-shaped frame 501, the clamping strip 510 is squeezed through the inside of the T-shaped frame 501, so that the two groups of clamping strips 510 are brought together.

[0027] Furthermore, please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the impact block 508 is designed in an arrow-shaped structure. The impact block 508 is adapted for use with the pressure block 502. Triangular blocks are symmetrically installed on the outside of the T-frame 501. The clamping strips 510 are brought close to each other, so that the clamping strips 510 clamp the protruding part of the impact block 508, thereby realizing the connection between the cover 3 and the paper bin 4.

[0028] For further information, see Figure 2 In this embodiment, a through slot 301 is provided inside the cover 3, and the cover 3 is interconnected with the inside of the paper bin 4 through the through slot 301. The cover 3 is hinged to the top of the electrocardiograph 1, and the through slot 301 is interconnected with the paper bin 4, so that the electrocardiograph paper can be printed better.

[0029] For further information, see Figure 2 In the present embodiment, a square groove is provided on the outside of the display 2 and inside the electrocardiograph 1, and an L-shaped groove 6 is provided on the inner wall of the square groove. The display 2 is slidably connected to the inside of the square groove through the L-shaped groove 6. By moving the display 2, the display 2 slides inside the L-shaped groove 6. When sliding to the top of the L-shaped groove 6, the display 2 is tilted to better observe the data.

[0030] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the electrocardiogram paper needs to be replaced, by pressing the cover 3, the impact block 508 squeezes the pressing block 502, thereby driving the spring 506 to contract, so that the card roller 507 slides inside the special-shaped groove 503, so that the card roller 507 is disengaged from the notch of the special-shaped block 504, so that the contraction force of the spring 506 is released, so that the top end of the pressing block 502 pops out of the T-shaped frame 501, and the squeezing of the card strip 510 is released through the inside of the T-shaped frame 501, so that the two groups of card strips 510 are unfolded, thereby releasing the fixation of the impact block 508, so that the cover 3 is separated from the paper bin 4, making it more convenient to replace the electrocardiogram paper, and by toggling the display 2, the display 2 slides inside the L-shaped groove 6. When it slides to the top of the L-shaped groove 6, the display 2 is tilted to better observe the data.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
