[0002] Medical monitoring equipment such as fetal monitors, electrocardiographs, defibrillators or ultrasonic diagnostic apparatuses usually include a host and a printing mechanism disposed in the host. Taking the printing mechanism of the fetal monitor as an example, the laminated thermal printing paper is usually installed in the printing paper bin. When the printing mechanism is working, the rubber pressure roller driven by the stepper motor rotates at a preset speed to drag the printing paper through the thermal printing head, thereby recording information such as curves representing the vital characteristics of the pregnant woman or the fetus on the thermal printing paper. The printing mechanism in the host records and prints data information in real time when the pregnant woman is monitored and sends the printing paper to the outside of the host. After the monitoring is completed, the operator tears the printing paper with the sharp edge of the cutting board above the paper outlet. Due to the structural and internal layout limitations of the existing printing mechanism, there is usually a delay of 80-110 seconds from printing the data information on the printing paper to sending the printing paper with the data information printed on it to the outside of the host, which can be seen by the operator. This means that there is also a certain degree of delay when the midwife or doctor needs to see the recorded data information as soon as possible. In an emergency, this delay may cause considerable harm.

Figure 1 As shown, the printing mechanism 1 of the medical monitoring device according to the utility model generally includes a support plate (or base plate) 3, and the support plate 3 is usually installed on the housing of the medical monitoring device (not shown) such as a fetal monitor. The printing mechanism 1 of the medical monitoring device according to the utility model also includes a support arm 5. In a preferred embodiment, the support arm 5 is generally L-shaped, and the support arm 5 is rotatably mounted on the support plate 3 at one end 5a. The support arm 5 is installed with a print head mounting portion 7 at its other end 5b, and a print head such as a thermal print head is mounted on the print head mounting portion 7. Figure 1In the figure, the print head is not visible because it is installed on the lower side of the print head installation part 7. The print head is electrically connected to the host of the medical monitoring device through wired or wireless communication, thereby receiving a signal from the host to perform a printing operation. The printing mechanism 1 of the medical monitoring device according to the utility model also includes a movable frame assembly 9, which is movably arranged on the support plate 3 and is located in the space between the support plate 3 and the support arm 5.

[0031] Figure 2 After removing the support arm and print head mounting part Figure 1 A cross-sectional view of the printing mechanism is shown in FIG. Figure 2 As shown, the movable frame assembly 9 includes a frame 11, a printing paper bin 15 mounted on the frame 11 and used to accommodate printing paper 13, and a rubber pressure roller 17 rotatably supported on the frame 11 at both ends. The rubber pressure roller 17 is rotatably supported at the front end of the two opposite side plates of the frame 11 close to the outside of the medical monitoring device through bearings, and the motor 20 installed at the rear end of the frame 11 spaced apart from the rubber pressure roller 17 can drive the rubber pressure roller 17 to rotate through a synchronous belt. A front end plate 19 is also installed at the front end of the frame 11 close to the outside of the medical monitoring device, close to the print head and the rubber pressure roller 17.

[0032] Figure 3 The front end plate 19 of the printing mechanism of the medical monitoring device according to the present utility model is schematically shown in a three-dimensional diagram.

Preferably, the cutting board 23 is made of a transparent material with high light transmittance, which makes the cutting board 23 also have the function of an observation window. In this way, in some special or emergency situations, the user or doctor can see the vital characteristics information of the pregnant woman or fetus recorded on the printing paper as early as possible through this transparent cutting board (or observation window). More preferably, at least one of the two side surfaces of the cutting blade 23a that defines the cutting board 23 is formed as a curved surface profile convex outward. In this way, the cutting board 23 plays a magnifying role similar to a convex lens, so as to magnify the text and curves printed on the printing paper to a certain extent, so as to further increase the visual distance and improve ease of use. In the preferred embodiment shown in the accompanying drawings, the side surface 23b of the two side surfaces of the cutting edge 23a of the cutting paper board 23 facing the inner side of the medical monitoring device is formed as a curved surface profile convex outwardly, but it should be understood that it is also feasible to form the side surface 23c of the two side surfaces of the cutting edge 23a of the cutting paper board 23 facing the outer side of the medical monitoring device as a curved surface profile convex outwardly, or it is also feasible to form both the side surface 23b of the two side surfaces of the cutting edge 23a of the cutting paper board 23 facing the inner side of the medical monitoring device and the side surface 23c facing the outer side of the medical monitoring device as curved surface profiles convex outwardly.

[0035] In addition, the portion of the cutting board 23 that is not used for observing the printed paper that has been printed with information but has not yet been sent out of the paper outlet 25 (for example, the portion 23d above the side surface 23b formed into a curved profile convex outward) can be subjected to a light-proof treatment such as frosting to increase the coverage area of ​​the light-proof portion so that the internal components are shielded as much as possible and are not easily visible from the outside.

[0036] According to the utility model, the cutting board used to define the paper outlet of the printing mechanism has an observation window and a magnifying function. In this way, in some special or emergency situations, the operator can see the information recorded on the printing paper as early as possible and clearly through the observation window before the printed printing paper is sent out of the paper outlet.

[0037] Although the utility model has been described in detail in conjunction with the preferred embodiments of the utility model, it should be understood that such detailed description is only used to explain the utility model and does not constitute a limitation of the utility model. For example, the cutting board for defining the paper outlet of the printing mechanism according to the utility model is not only used for the printing mechanism of medical monitoring equipment, but can be used in all printers where the printed paper needs to be seen before being sent out of the paper outlet. The scope of the utility model is determined by the technical solution defined in the claims.
