technical field

The invention relates to a medical instrument, in particular to a medical fetal heart instrument.

Background technique

The fetal heart rate monitor is mainly used as an electronic instrument for fetal heart rate monitoring. Before the detection of the general fetal heart rate monitor, the head of the probe needs to be coated with couplant and alcohol to facilitate disinfection. The couplant and alcohol of the fetal heart rate monitor are usually loaded inside the fetal heart rate monitor and supplied through a push-type outlet. But the problem is that during each use of this fetal heart rate monitor, the position of the screen, the inclination of the screen, the switch of the cover plate on the push-type outlet, and the position of the handle all need to be adjusted. Since the manual adjustment times are frequent, it is extremely inconvenient to use. , In addition, when the fetal heart device is not in use, the user often forgets to close the cover plate on the push-type outlet, which leads to the breeding of bacteria and dust, which is not conducive to the use of hygiene.

Detailed ways

In order to make those skilled in the art better understand the technical solutions of the present invention, the present invention will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present invention. Not all, based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

As shown in Figures 1 to 5, a medical fetal heart instrument includes a body 1, a handle 2, a screen 3 and a drawer 4; the left and right sides of the handle 2 are fixedly connected to the body 1 through bearings. The short axis 5.

The fuselage 1 is provided with a locking assembly adapted to the stub shaft 5; a gear 10 is installed on each stub shaft 5, the gear 10 is meshed with a rack 11, and the two racks 11 are connected together with a gear 10. Lifting plate 12 .

The front part of the fuselage 1 is provided with two press-type outlets 15 , the top of the press-type outlets 15 is covered with a cover plate 16 hingedly mounted on the fuselage 1 , and the bottom of the cover plate 16 abuts against a lift plate welded on the lift plate. 12 Push rod 17 at the upper end.

The locking assembly includes limit plates 6 fixed on the left and right outer sides of the fuselage 1 respectively. The limit plates 6 are L-shaped, and the limit plates 6 abut against the short shaft 5 and the handle 2; Any one of the limiting plates 6 in the plates 6 is installed with two spring pin structures.

Each spring pin structure is composed of a frame body frame 7, a spring 8 and a plug pin 9; the frame body frame 7 is fixedly installed on the limit plate 6, and the plug pin 9 is slidingly matched with the frame body frame 7 and the limit plate 6; The spring 8 is connected between the latch 9 and the frame body frame 7 .

There are two sockets 5 a matched with the plug pins 9 on the corresponding short shaft 5 of the two short shafts 5 .

The screen 3 is hingedly mounted on the upper side of the fuselage 1 , and the bottom of the screen 3 is fixedly connected with a linkage plate 13 abutting against the lifting plate 12 .

The linkage plate 13 is in the shape of an arc, and the center position of the linkage plate 13 is adapted to the position of the hinge point of the screen 3 on the fuselage 1; Guide frame 14.

An alcohol bottle 18 and a couplant bottle 19 are placed inside the drawer 4 respectively; the alcohol bottle 18 and the couplant bottle 19 are respectively connected with leather tubes;

In the present invention, a storage slot is also provided on the right side of the fuselage 1, and the probe 20 is placed inside the storage slot. The alcohol bottle 18 and the couplant bottle 19 are respectively used for storing the alcohol and the couplant, and the couplant and the alcohol can be sprayed upward through the pressing outlet 15 to facilitate the probe to be dipped.

The main feature of the present invention is that it is convenient to switch between the working state and the carrying state. That is, it is realized by rotating the handle 2 by 90 degrees, that is, when the handle 2 is in a horizontal state, the present invention is in a carrying state, which is convenient for manual hand-carrying. When the handle 2 is in the vertical state, it is in the working state.

Specifically, when actual use is required, it is only necessary to release the engagement between the latch 9 located on the front side and the socket 5a, and then rotate the handle 2 and the short shaft 5 clockwise by 90 degrees, and then rotate the latch located on the lower side by 90 degrees. 9 cooperates with the socket 5a under the action of the spring 8, thereby producing a locking effect. In addition, when the gear 10 rotates with the short shaft 5, it can drive the rack 11 and the lifting plate 12 to slide upward, so as to realize the lifting of the screen 3 and the cover plate 16 upward, so that the screen 3 is rotated to a tilted state, which is convenient for use and observation. The cover plate 16 is also rotated to open, so that the push-type outlet 15 is exposed, which is convenient for the probe to be dipped.

In addition, when not in use, both the handle 2 and the short shaft 5 need to be rotated 90 degrees counterclockwise, so that the gear 10 moves downward, that is, the screen 3 and the cover plate 16 are automatically dumped to a horizontal state under gravity, and the cover plate 16 can effectively play a protective role after covering the pressing outlet 15 again, which is relatively convenient to use.
