[0001] The utility model belongs to the technical field of medical equipment, in particular to a fetus growth and development monitoring plate. Background Art

[0002] Monitoring fetal growth and development is a crucial aspect of pregnancy. Monitoring discs (also known as gestational week discs) are often used to calculate the due date and assess fetal growth and development during each stage of pregnancy. Existing monitoring discs are multi-layered rotating discs, and the entire pregnancy period is approximately 10 months. Dust easily accumulates on these discs after prolonged use, making them difficult to clean. Utility Model Content

[0003] The purpose of the utility model is to provide a fetal growth and development monitoring plate to solve the problem in the above background technology that dust easily accumulates on the monitoring plate and it is inconvenient to clean the dust.

Based on the transparent material of the outer shell, the contents on the monitoring panel body inside the shell can be directly viewed through the shell cover. After the shell cover is removed and opened, the turntable of the monitoring panel body can be rotated according to the gestational age, so as to evaluate the growth and development of the fetus by comparing it with the standard reference value of the fetal growth and development at the gestational age stage.

[0006] Further restrictions, the monitoring disk body is a multi-layer turntable structure, and the multi-layer turntables are connected by tubular rivets. Each layer of the turntable can rotate around the tubular rivets, and there is a certain friction between the two adjacent layers of turntables, which can prevent them from rotating easily, and the turntable of the monitoring disk body can be rotated according to the gestational age; a locking piece for fixing the monitoring disk body is provided inside the shell; the locking piece includes a first screw fixed to the bottom of the shell, the first screw is passed through the tubular rivet, and the end of the first screw is threadedly connected to a first nut for clamping and fixing the monitoring disk body. Tightening the first nut can clamp the monitoring disk body to the inner bottom surface of the shell. Based on the extrusion of the first nut and the fact that each turntable of the monitoring disk body is made of coated paper or plastic with a certain deformation ability, the turntables of each layer of the monitoring disk body can be pressed and fixed to prevent the turntables of each layer of the monitoring disk body from rotating easily. After loosening the first nut, the turntable of the monitoring disk body can be manually rotated.

[0007] As a further limitation, the inner bottom of the shell is provided with an annular relief groove for the tubular rivet to penetrate. After tightening the first nut, the back of the monitoring disk body can fit tightly against the inner bottom surface of the shell, thereby improving the stability of the monitoring disk body.

A hanging hole is opened on the hanging plate, and the hanging plate can be hung on a nail or hook on the wall, so that the monitoring panel can be hung on the wall for easy viewing.

[0009] As a further limitation, one side outer wall of the shell is connected to the one side outer wall of the shell cover by a hinge, so that the shell cover can be flipped open and closed relative to the shell, and a lock for locking the shell cover is provided on the other side of the shell cover. After the shell cover is flipped closed, the lock can be used to lock the shell cover to prevent it from opening automatically.

[0010] As a further limitation, the hinge is arranged on the left side wall, right side wall, top or bottom of the shell and the shell cover, so that the shell cover can be flipped open to the left, flipped open to the right, flipped open to the upper side or flipped open to the lower side respectively.

[0011] Further restrictions, the lock includes a second screw, a orifice plate and a second nut, one end of the second screw is fixed on the annular flange, the orifice plate is fixed on the outer wall of the shell cover, the orifice plate is sleeved on the second screw, and the second nut is threadedly connected to the other end of the second screw for locking the orifice plate. After removing the second nut, the shell cover can be flipped open and the orifice plate is separated from the second screw.

[0012] Further restrictions, the open end of the shell and the open end of the shell cover are both provided with an annular step, the shell cover and the shell are fastened at the concave and convex overlap, and a sealing gasket is fixed on the annular step surface of the shell. The above structure can improve the stability of the fastening structure between the shell cover and the shell and improve the sealing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The monitoring panel can be used to calculate the expected date of delivery during pregnancy and estimate the growth and development of the fetus by comparing it with various stages of pregnancy. The monitoring panel body can be installed inside the shell. After covering the shell cover, the monitoring panel body can be shielded and protected, which is not only dust-proof, but also splash-proof and scratch-proof. Based on the transparent material of the shell, the contents on the monitoring panel body inside the shell can be directly viewed through the shell cover. After removing and opening the shell cover, the turntable of the monitoring panel body can be rotated according to the gestational age, so as to evaluate the growth and development of the fetus by comparing it with the standard reference values ​​of fetal growth and development at the gestational age stage (such as standard reference values ​​of femoral length, biparietal diameter, abdominal circumference, etc.). After long-term use, when dust adheres to the outer surface of the shell, the dust can be cleaned with a wet cloth. Even if the monitoring panel body is used for a long time, too much dust will not accumulate, and there is no need to clean the monitoring panel body. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] A fetal growth monitoring disc, such as Figure 1 and Figure 3 As shown, it mainly consists of a monitoring panel body 1 and a shell 2 wrapped around the outside of the monitoring panel body 1 for protecting the monitoring panel body 1.

[0025] like Figures 1 to 4 As shown, the monitoring disk body 1 is a multi-layer turntable structure, and the multi-layer turntables are connected by tubular rivets 10. Each layer of the turntable can rotate around the tubular rivet 10, and there is a certain friction between the two adjacent layers of turntables, which can prevent them from rotating easily, so that it is convenient to manually rotate the turntable to adjust the gestational age on the monitoring disk body 1; each turntable of the monitoring disk body 1 is made of coated paper or plastic (such as PP plastic or PVC plastic, etc.); the above-mentioned monitoring disk body 1 is an existing product, which is sold online and offline and can be purchased and used.

[0026] like Figure 1 and Figure 3 As shown, the housing 2 includes a shell 2.1 and a shell cover 2.2 detachably connected to the shell 2.1;

[0027] like Figure 1 and Figure 3 As shown, one side outer wall of the housing 2.1 is connected to one side outer wall of the housing cover 2.2 by a hinge 4, so that the housing cover 2.2 can be flipped open and closed relative to the housing 2.1. The other side of the housing cover 2.2 is provided with a lock 8 for locking the housing cover 2.2. After the housing cover 2.2 is flipped closed, the lock 8 can be used to lock the housing cover 2.2 to prevent it from opening automatically.

[0028] like Figure 1 As shown, the hinge 4 is provided on the left side wall of the housing 2.1 and the shell cover 2.2, and the lock 8 is provided on the right side of the shell cover 2.2, so that the shell cover 2.2 can be flipped open to the left; in addition, as shown Figure 2As shown, the hinge 4 can also be set at the bottom of the shell 2.1 and the shell cover 2.2, and the lock 8 is set at the top of the shell cover 2.2, so that the shell cover 2.2 can be flipped open to the bottom, wherein it is more convenient to flip the shell cover 2.2 to the left or right.

[0029] like Figures 1 to 3 As shown, the back of the shell 2.1 is integrally formed with an annular flange 3, and a hanging plate 5 is provided on the top of the annular flange 3. The hanging plate 5 is provided with a hanging hole 6, which can be hung on a nail or hook on the wall, so that the monitoring panel can be hung on the wall for easy viewing.

[0030] like Figure 3 and Figure 5 As shown, the lock buckle 8 includes a second screw 8.1, a hole plate 8.2 and a second nut 8.3. One end of the second screw 8.1 is fixed on the annular flange 3, and the hole plate 8.2 is fixed to the outer wall of the shell cover 2.2. The hole plate 8.2 is sleeved on the second screw 8.1, and the second nut 8.3 is threadedly connected to the other end of the second screw 8.1 for locking the hole plate 8.2. After removing the second nut 8.3, the shell cover 2.2 can be flipped open and the hole plate 8.2 is separated from the second screw 8.1; in addition, the lock buckle 8 can also be composed of a first plate, a second plate, an iron sheet embedded in the first plate and a magnet embedded in the second plate. The first plate and the second plate are respectively fixed to the outer wall of the shell 2.1 and the outer wall of the shell cover 2.2. When the shell cover 2.2 is flipped over, the iron sheet is magnetically connected to the magnet, thereby locking the shell cover 2.2. Compared with the magnetic connection method, the structure of fastening the hole plate 8.2 with the second nut 8.3 is more stable and reliable.

[0031] like Figure 3 and Figure 5 As shown, the open end of the shell 2.1 and the open end of the shell cover 2.2 are both provided with an annular step, and the shell cover 2.2 and the shell 2.1 are joined at a concave-convex overlap, and a sealing gasket 11 is fixed on the annular step surface of the shell 2.1. The above structure can improve the stability of the snap-fit ​​structure between the shell cover 2.2 and the shell 2.1 and improve the sealing performance, and can prevent dust from entering the shell 2.1 through the gap at the snap-fit ​​between the shell cover 2.2 and the shell 2.1.

[0032] like Figures 1 to 4As shown, the interior of the housing 2.1 is provided with a locking piece 7 for fixing the monitoring disk body 1; the locking piece 7 includes a first screw 7.1 fixed to the inner bottom of the housing 2.1, the first screw 7.1 is inserted into the tubular rivet 10, and the end of the first screw 7.1 is threadedly connected with a first nut 7.2 for clamping and fixing the monitoring disk body 1. Tightening the first nut 7.2 can clamp and fix the monitoring disk body 1 to the inner bottom surface of the housing 2.1; based on the extrusion of the first nut 7.2 and the fact that each turntable of the monitoring disk body 1 is made of coated paper or plastic with a certain deformation ability, the turntables of each layer of the monitoring disk body 1 can be pressed and fixed to prevent the turntables of each layer of the monitoring disk body 1 from rotating easily. After loosening the first nut 7.2, the turntable of the monitoring disk body 1 can be manually rotated;

[0033] like Figure 4 As shown, the inner bottom of the shell 2.1 is provided with an annular clearance groove 9 for the tubular rivet 10 to penetrate. After tightening the first nut 7.2, the back of the monitoring disk body 1 can be closely fitted to the inner bottom surface of the shell 2.1, thereby improving the stability of the monitoring disk body 1. After removing the first nut 7.2, the monitoring disk body 1 can be taken out.

[0034] The housing 2.1 and the housing cover 2.2 are both made of transparent materials, specifically acrylic materials, with high transparency. The monitoring panel body 1 can be placed in the housing 2.1. After the housing cover 2.2 is closed, the monitoring panel body 1 can be shielded and protected from dust, splashing water, and scratches.

[0035] Due to the transparent material of the outer shell 2, the contents on the monitoring disk body 1 inside the housing 2.1 can be directly viewed through the shell cover 2.2. After flipping open the shell cover 2.2, the dial of the monitoring disk body 1 can be rotated according to the gestational age, so as to evaluate the growth and development of the fetus by comparing it with the standard reference value of fetal growth and development at that gestational age.

[0036] In addition, the suspension plate 5 and the annular flange 3 are integrally formed with the shell 2.1 and are all made of acrylic material.

[0037] The operating principle of the monitoring disk in this embodiment is:

[0038] When using the monitoring disc to monitor fetal growth and development, the purchased monitoring disc body 1 is installed in the housing 2.1. Specifically, the tubular rivet 10 on the monitoring disc body 1 is sleeved onto the first screw 7.1 at the bottom of the housing 2.1. The first nut 7.2 is installed at the end of the first screw 7.1 and tightened to lock the monitoring disc body 1. When the turntable of the monitoring disc body 1 is rotated according to the gestational age, the turntable of the monitoring disc body 1 can be rotated by loosening the first nut 7.2. After the adjustment is completed, the first nut 7.2 is tightened to lock the monitoring disc body 1. The fetal growth and development can be evaluated by comparing the standard reference values ​​of fetal growth and development according to the gestational age (for example, standard reference values ​​of femoral length, biparietal diameter, abdominal circumference, etc.) on the monitoring disc body 1. The monitoring disc body 1 can be disassembled and replaced;

[0039] The shell cover 2.2 is turned over to engage with the housing 2.1. The orifice plate 8.2 on the side wall of the shell cover 2.2 is placed on the second screw 8.1. The second nut 8.3 is installed at the end of the second screw 8.1 and tightened to lock the orifice plate 8.2, thereby locking the shell cover 2.2. The buckling part between the shell cover 2.2 and the housing 2.1 has a concave-convex overlap, and the sealing gasket 11 is used to increase the tightness and prevent dust from entering the housing 2.1 and contaminating the monitoring disk body 1. Due to the transparent material of the housing 2, the contents of the monitoring disk body 1 inside the housing 2.1 can be directly viewed through the shell cover 2.2.

[0040] When dust adheres to the outer surface of the shell 2, the dust can be cleaned with a wet cloth. Even if the monitoring panel body 1 is used for a long time, too much dust will not accumulate, and there is no need to clean the monitoring panel body 1. In addition, the monitoring panel body 1 is hidden in the shell 2, and the shell 2 can also prevent water splashing and scratching the monitoring panel body 1.
