It will be apparent that the described embodiments are some, but not all, embodiments of the application. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the application, fall within the scope of protection of the application.

A size adjustable dummy pod according to an embodiment of the present application will be described in detail with reference to the accompanying drawings.

Specifically, as shown in fig. 1 and 2, the embodiment of the present application provides a size-adjustable premature infant simulation capsule, which includes a base 10, a base member and a limiting member.

The base 10 is provided with a first groove 110, the base piece comprises a head base plate 21 and a tail base plate 22, the head base plate 21 and the tail base plate 22 are spliced to form the base piece of the simulation cabin, the head base plate 21 is connected to one end of the base 10 and corresponds to the head position of a premature infant, the tail base plate 22 is connected to the base 10, the head base plate 21 and/or the tail base plate 22 can move relative to the base 10, a through groove 22a is formed in the head base plate 21 and/or the tail base plate 22 which can move relative to the base 10, and the through groove 22a is matched with the first groove 110.

Specifically, when only the head chassis 21 is movable relative to the base 10, the through groove 22a is provided on the head chassis 21; when only the tail bottom plate 22 can move relative to the base 10, a through groove 22a is arranged on the tail bottom plate 22; when both the head chassis 21 and the tail chassis 22 are movable relative to the base 10, through grooves 22a may be provided on the head chassis 21 and the tail chassis 22, respectively. Thus, the head floor 21 and/or the tail floor 22 may be secured relative to the base 10 by the stop block 310 when moved to a desired position.

The limiting member includes a limiting block 310, the limiting block 310 is matched with the through groove 22a and the first groove 110, and the limiting block 310 is used for limiting the relative positions of the head bottom plate 21, the tail bottom plate 22 and the base 10.

That is, the head bottom plate 21/the tail bottom plate 22 can move relative to the base 10 to adjust the size of the space in the cabin, so as to be suitable for premature infants with different sizes, and the limiting block 310 is used to limit the relative position between the base 10 and the bottom plate member after the adjustment to a proper size, that is, the bottom plate member is locked on the base 10, so that the movement is avoided in the use process.

Here, the limiting member may be a separate detachable member or may be connected to the base 10.

In one embodiment, the limiting member includes a connecting portion, where one end of the connecting portion is connected to the base 10 and the other end is connected to the limiting member 310, and the connecting portion is a deformable flexible member such as a plastic tape, a silicone tape, or the like.

It should be noted that fig. 1 and 2 only show the case where the length direction is adjustable. In fact, instead of being adjustable in the length direction, width direction adjustment may be achieved based on the same principle. For example, taking the case that the width of the head chassis 21 is adjustable, the head chassis 21 may be composed of two parts, i.e., a left side and a right side, in which the left side and/or the right side may be moved with respect to the base 10, and after being adjusted to a desired size, may be fixed to the base 10 by a stopper as well. Regarding the specific structure, those skilled in the art can appropriately change the design with reference to the above-mentioned embodiment with adjustable length, and detailed descriptions thereof will be omitted herein.

In an embodiment, as shown in fig. 3, the stopper 310 is provided with a second groove 311 and a handle 312, the handle 312 is located in the second groove 311, and the top of the handle 312 is lower than the surface of the stopper 310.

That is, the second groove 311 forms a space for the operator to take and place the handle 312, and the handle 312 does not protrude from the surface of the stopper 310, so that the flatness of the surface of the bottom plate member can be ensured, and the lying comfort of the premature infant can be ensured.

In another embodiment, the stopper 310 is a spherical crown-shaped or frustum-shaped elastic protrusion formed on the base 10, and the height of the elastic protrusion may be approximately equal to the thickness of the base plate member, when moving the head/tail base plate 21, 22, since the elastic protrusion does not affect its movement, when moving to the position where the elastic protrusion exactly matches the through groove 22a on the tail base plate 22.

In an embodiment, the simulation pod further includes a first transmission member 40, where the first transmission member 40 includes a first gear 420 and a first rack 410, where the first gear 420 engages the first rack 410, the first gear 420 is mounted on the base 10, and the first rack 410 is connected to the bottom of the tail sole plate 22 and/or the head sole plate 21. The base 10 is provided with a third groove 120, the first transmission member 40 is located in the third groove 120, and when the tail bottom plate 22 and/or the head bottom plate 21 are subjected to an external force, the tail bottom plate 22 and/or the head bottom plate 21 moves along with the first rack 410.

That is, the first transmission member 40 is located below the surface of the base 10 to enhance the fit between the surface of the base 10 and the floor member. By the first gear 420 engaging the first rack 410, stability during adjustment of the floor member is improved.

Here, fig. 2 shows only one rack 410, in other words, fig. 2 shows only a case where one of the head chassis 21 and the tail chassis 22 is connected to the rack 410 to move by the rack 410. In the case where both the head chassis 21 and the tail chassis 22 are movable, two first racks 410 may be provided in parallel at both sides of the first gear 420, respectively, to drive the head chassis 21 and the tail chassis 22 to move by connecting the two first racks 410, respectively.

The premature infants from 28 weeks to 37 weeks have a large difference in length, and premature infants of different lengths can be accommodated by pushing and pulling the tail base plate 22 to move toward or away from the head base plate 21, i.e., adjusting the size of the premature infant in the length direction.

In one embodiment, the floor member further includes a first infill floor that matches the first space when there is a first space between the tail floor 22 and the head floor 21.

That is, when the floor area needs to be enlarged, a first space exists between the adjusted head floor 21 and the tail floor 22, and the first filling floor is inserted into the first space, so that the head floor 21, the first filling floor and the tail floor 22 are spliced to form a flat floor, so as to ensure the lying comfort of the premature infant. Of course, when it is desired to reduce the floor element area, the first filler floor can be removed and the tail floor 22 can be adjusted.

The area of the first filling floor corresponds to the distance between the first through groove 22a1, the second through groove 22a2, and the third through groove 22a 3.

Premature infants from 28 weeks to 37 weeks have not only large differences in length, but also differences in width. In order to meet different requirements of premature infants with large differences, the embodiment of the application not only can adjust the length direction of the premature infants, but also can adjust the width direction of the premature infants so as to improve the suitability of the simulation cabin and the physical constitution of the premature infants.

The simulation cabin further comprises a second transmission member 50, the second transmission member 50 has the same structure as the first transmission member, the second transmission member 50 is located in the third groove 120, and the transmission direction of the second transmission member 50 is perpendicular to the length direction of the simulation cabin.

The first bottom plate 211 is fixedly connected with the base 10, the second bottom plate 212 is connected with the second transmission member 50, the third bottom plate 221 is simultaneously connected with the first transmission member 40 and the second transmission member 50, the fourth bottom plate 222 is connected with the first transmission member, the third bottom plate 221 and the fourth bottom plate 222 move along the length direction of the simulation cabin under the transmission of the first transmission member 40, and the second bottom plate 212 and the third bottom plate 221 move along the width direction of the simulation cabin under the transmission of the second transmission member 50.

That is, the floor member is divided into four parts, i.e., a first floor 211, a second floor 212, a third floor 221 and a fourth floor 222, wherein the first floor 211 is fixedly connected with the base 10, and when it is required to adjust the size along the length direction of the premature infant, an operator applies an external force to the third floor 221 and the fourth floor 222, and increases or decreases the length of the floor member under the action of the first transmission member 40. When it is necessary to adjust the size in the width direction of the premature infant, the operator applies an external force to the second base plate 212 and the third base plate 221, and the width of the base plate member is increased or decreased by the second transmission member 50.

The embodiment not only can adjust the length of the simulation cabin, but also can adjust the width of the simulation cabin so as to be suitable for premature infants with different sizes in a larger range, and the simulation cabin with various models is not required to be provided.

The simulated cabin provided by the embodiment of the application is used for monitoring the sleep and activity of premature infants pregnant for 36 weeks for one week, and the specific data for carrying out statistical analysis on the clinical data are shown in the following table 2.

TABLE 2 intervention group of clinical data of pregnant 36 weeks premature infants (i.e., using the adjustable simulation pod of the present application) versus blank (i.e., existing larger sized simulation pod) sleep and activity data over a 24 hour period

As can be seen from table 2, the clinical data of the premature infant with the period of 36 weeks shows that, for the average value of the activity mean (mean) in the period of 24 hours, the intervention group number is 49.9609, the blank control number is 58.7472, and the simulation cabin of the present application is used to reduce the daily activity of the premature infant when the boundary is applied to the premature infant, that is, effectively reduce or relieve the spontaneous limb activity in the stress state, and prompt Bao Rao that the applied boundary can make the premature infant obtain the security sense similar to the package of the maternal uterine wall, effectively promote the physiological stability, and facilitate rest and sleep.

Furthermore, the average value of the 24h longest awakening segment (i.e., l gwep) was 76.2963 for the intervention group and 114.2794 for the blank, which is indicative of a reduced awakening time for the longest period of 24 hours in premature infants, i.e., a reduced period of non-sleep for a long period of time, using the simulation pod of the present application to provide boundary fit to premature infants.

Furthermore, the average 24 hour average sleep fraction (i.e., msep) had an intervention group number of 35.3891 and a blank control number of 20.1926, which is indicative of the increased duration of each sleep fraction in 24 hours for premature infants using the simulation pod of the present application to provide boundary fit to the premature infant.

Further, for the average value of the 24-hour longest sleep segment (i.e., lgsep), the intervention group number was 199.7075 and the blank control number was 140.7423, which indicates that the longest sleep time in 24 hours of premature infants was increased and the sleep quality of premature infants was improved by using the simulation pod of the present application to make boundary fit to premature infants.

As can be seen from table 2, premature infants were able to reduce activity, increase sleep time and improve sleep quality in the simulated cabins in which they fit.

In addition, in order to examine whether the two groups of samples (i.e., the intervention group and the control group) are normally distributed, a variance alignment test was performed, and the test results are shown in table 3 below.

TABLE 3 results of the variance testing of clinical data for one week of premature infants pregnant for 36 weeks

As can be seen from table 3, the significance of the amean t test was less than 0.05, indicating a difference between the intervention group and the control group, which further verifies the results obtained in table 2, indicating a reduction in the mean activity of premature infants in the case of boundary fitted premature infants using the simulation pod of the present application. Furthermore, the significance of the t-test for lwep was less than 0.01, indicating a significant difference between the intervention group and the control group, which further verifies the results obtained in table 2, indicating a significant improvement in the maximum 24 hour wake-up time of premature infants with boundary fitted premature infants using the simulation pod of the present application.

Although msep, the average 24-hour wake-up period, and lgsep, the t-test of the 24-hour longest sleep period, were slightly more significant than 0.05, they were also relatively close to 0.05, indicating some difference in the case of the intervention group relative to the control group, and the corresponding improvements in the average 24-hour wake-up period and the 24-hour longest sleep period were shown in conjunction with table 2.

In summary, as shown in the results of the average analysis and the variance alignment test analysis of clinical data of a week for a premature infant with 36 weeks of gestation, the simulated cabin provided by the application can reduce the activity of the premature infant, increase the sleep time and improve the sleep quality, and different premature infants can improve the activity and sleep of the premature infant in the simulated cabin matched with the physical constitution of the premature infant, so that the rapid growth of the premature infant can be promoted.

While the foregoing is directed to the preferred embodiments of the present application, it will be appreciated by those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present application, and such modifications and adaptations are intended to be comprehended within the scope of the present application.
