Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a handheld neonatal auxiliary expectorant. Background Art

[0002] In clinical care, expectorants can vibrate and squeeze phlegm trapped in the lungs or trachea, providing directional drainage and assisting in the expulsion of phlegm from the body. However, for newborns, due to their small size, there are no suitable expectorants on the market. Nurses must manually tap their backs to expel phlegm, which is difficult to care for. Furthermore, the positioning, frequency, and force of manual tapping are difficult to control, which can easily cause discomfort to the newborn.

[0003] To address these issues, Chinese patent CN213048101U discloses a handheld electric expectorant for neonates. This handheld electric expectorant is simple to operate and easy to use. A vibrating mechanism drives a percussion head to vibrate, simulating manual back percussion for expectoration. However, the percussion head of this electric expectorant simply uses a sponge (the limit plate in this document) wrapped directly on a connecting plate. When the percussion head vibrates, the vibration force is directly transmitted to the neonate's back, which can cause excessive stress on the neonate's back. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a handheld neonatal auxiliary expectorant, which has a uniform and gentle vibration force, can help neonates expectorate, and avoid excessive stress on the neonates' backs. The technical solution adopted is as follows:

[0005] A handheld neonatal auxiliary expectorant comprises a handle and a vibrating head, wherein a vibration drive device is installed in the handle, and an output shaft of the vibration drive device extends out of the upper end of the handle and is plugged into and matched with a plug interface of the vibrating head. The invention is characterized in that: the vibrating head comprises a head frame and a contact piece, and the plug interface is arranged at the lower end of the head frame; the interior of the head frame is hollow and filled with a buffer material; and the contact piece is covered on the outside of the head frame.

[0006] The head frame is set to be hollow and filled with cushioning material. When the vibrating head vibrates, the vibration force of the head frame will be dispersed and reduced by the cushioning effect of the cushioning material, so that the vibration force of the contact parts that finally act on the back of the newborn becomes uniform and gentle, and the instantaneous impact force on the back of the newborn is greatly reduced. It can not only help the newborn to expectorate, but also avoid excessive force on the back of the newborn.

[0007] The above-mentioned vibration driving device generally includes a vibration motor and related control circuits to drive its output shaft to generate vibration, thereby driving the entire vibration head to vibrate. This is a very mature existing technology and will not be described in detail here.

[0008] The above-mentioned buffer material can be made of sponge, rubber, silicone, or even fluid material.

[0009] The handle is usually also provided with a USB charging port; the vibration drive device is generally also provided with multiple adjustment gears on the handle to provide vibration frequencies of different intensities.

[0010] As a preferred solution of the present invention, the contact piece includes two soft vibration wrapping sheets, which respectively cover the front and rear sides of the head frame; the outer side surfaces of the two soft vibration wrapping sheets serve as contact surfaces, and the outer side surfaces of the soft vibration wrapping sheets are arc-shaped convex surfaces.

[0011] The outer surface of the soft vibration wrapping sheet serves as the contact surface and contacts the back of the newborn when in use. When the vibration head vibrates, the vibration force is first dispersed by the buffer material in the inner cavity, and then further diluted by the soft vibration wrapping sheet, so that the vibration force becomes softer when it reaches the back of the newborn.

[0012] The soft vibration package sheet can be made of soft rubber or silicone.

[0013] The radian of the above-mentioned curved convex surface is generally small, so that the entire curved convex surface is relatively flat, making the back of the newborn more comfortable.

[0014] As a further preferred embodiment of the present invention, one of the two arc-shaped convex surfaces is a smooth surface, and the other surface is provided with a plurality of convex points. The plurality of convex points are provided on one of the arc-shaped convex surfaces, which can be used for tactile training.

[0015] As a further preferred solution of the present invention, the edge of the soft vibration package is sleeved on the head frame.

[0016] As a further preferred solution of the present invention, an annular groove is provided on the head frame along its circumference, and the edge of the soft vibration package is sleeved in the annular groove.

[0017] As a further preferred solution of the present invention, the edge of the soft vibration packing sheet is an elastic edge. The elastic edge is directly sleeved in the annular groove, so that the soft vibration packing sheet is directly sleeved on the head frame, which is convenient for replacement.

[0018] As a further preferred embodiment of the present invention, the head frame includes an annular outer ring, a front concave piece, and a rear concave piece. The edge of the front concave piece is correspondingly connected to the front edge of the annular outer ring, and the edge of the rear concave piece is correspondingly connected to the rear edge of the annular outer ring. The annular outer ring, the front concave piece, and the rear concave piece form a sealed inner cavity, and the buffer material is filled in the inner cavity. The plug-in interface is provided at the lower end of the annular outer ring. The inner side surfaces of the two soft vibration wrapping pieces are respectively provided with convex portions that fit correspondingly with the concave portions of the front concave piece and the rear concave piece. The vibration force is transmitted from the plug-in interface at the lower end of the annular outer ring to the inner cavity, and is buffered by the buffer material and dispersed in all directions and gradually weakened until it reaches the soft vibration wrapping piece that contacts the newborn's back. The vibration force becomes soft and uniform, with small impact force, which is more suitable for the newborn's delicate back muscles.

[0019] As a further preferred embodiment of the present invention, the head frame further includes an inner bracket; the inner bracket is provided with multiple connection points along its circumference, and is connected to the inner wall of the annular outer ring through the connection points; the buffer material wraps around the inner bracket. An inner bracket is added inside the annular outer ring to support the annular outer ring from the inside, further reducing the vibration amplitude of the annular outer ring and making the vibration force transmitted to the soft vibration package more gentle.

[0020] As a further preferred embodiment of the present invention, at least one of the connection points is connected to the plug interface. When the vibration force is transmitted from the plug interface to the inner cavity, it is transmitted to the inner bracket via the connection point connected to the plug interface, and then transmitted to the upper portion of the annular outer ring via the inner bracket. This prevents the vibration force from being excessively concentrated near the plug interface, and makes the vibration force more evenly distributed on the upper and lower parts of the soft vibration package.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] The handheld neonatal auxiliary expectorant of the utility model is designed to have a hollow head frame of the vibrating head and to be filled with cushioning material. When the vibrating head vibrates, the vibration intensity of the head frame is dispersed and reduced by the cushioning effect of the cushioning material, so that the vibration intensity of the contact piece that ultimately acts on the back of the neonate becomes uniform and gentle, and the instantaneous impact force on the back of the neonate is greatly reduced, which can not only help the neonate to expectorate, but also avoid excessive force on the back of the neonate.

DETAILED DESCRIPTION

[0028] The following is a further description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown, a handheld neonatal auxiliary expectoration device includes a handle 1 and a vibrating head 2. A vibration drive device is installed in the handle 1. The output shaft of the vibration drive device extends from the upper end of the handle 1 and is plugged into the plug interface 4 of the vibrating head 2. The vibration drive device generally includes a vibration motor and a related control circuit to drive its output shaft to vibrate, thereby driving the entire vibrating head 2 to vibrate. This is a very mature existing technology and will not be described in detail here. Figure 1 Only the external structure of this embodiment is shown in the figure. The handle 1 is usually provided with a USB charging port 3; the vibration drive device is generally also provided with multiple adjustment gears on the handle 1 to provide vibration frequencies of different intensities.

[0030] like Figure 2 and Figure 3 As shown, the vibration head 2 includes a head frame 21 and a contact piece; the head frame 21 includes an annular outer ring 211, a front concave piece 212 and a rear concave piece 213, the edge of the front concave piece 212 is correspondingly connected to the front edge of the annular outer ring 211, the edge of the rear concave piece 213 is correspondingly connected to the rear edge of the annular outer ring 211, the plug interface 4 is arranged at the lower end of the annular outer ring 211, and the annular outer ring 211 is provided with an annular groove 214 along its circumference; the contact piece includes two soft vibration wrapping pieces 220, the two soft vibration wrapping pieces 220 are respectively covered on the front and rear sides of the head frame 21, the edges of the two soft vibration wrapping pieces 220 are sleeved in the annular groove 214, the edges of the soft vibration wrapping pieces 220 are elastic edges 224, which are directly sleeved in the annular groove 214, so that the soft vibration wrapping pieces 220 are directly sleeved on the head frame 21, which is convenient for replacement. The soft vibration package 220 can be made of soft rubber or silicone.

[0031] like Figure 2 and Figure 3 As shown, the outer side surfaces of the two soft vibration wraps 220 are both arc-shaped convex surfaces 221 as contact surfaces. The curvature of the arc-shaped convex surface 221 is generally small, so that the entire arc-shaped convex surface 221 is relatively flat, making the back of the newborn more comfortable; one of the arc-shaped convex surfaces 221 is a smooth surface, and the surface of the other arc-shaped convex surface 221 is provided with multiple convex points 222, which can be used for tactile training; the inner side surfaces of the two soft vibration wraps 220 are respectively provided with convex parts 223 that correspond to the concave parts of the front concave piece 212 and the rear concave piece 213.

[0032] like Figure 3 and Figure 4 As shown, the annular outer ring 211, the front concave piece 212 and the rear concave piece 213 constitute a sealed inner cavity, and the head frame 21 also includes an inner bracket 215. The inner bracket 215 is provided with multiple connection points 216 along its circumference. The inner bracket 215 is connected to the inner wall of the annular outer ring 211 through the connection points 216. There is at least one connection point 216 connected to the plug interface 4 (one in this embodiment); the buffer material 5 is filled in the inner cavity and wraps the inner bracket 215. The buffer material 5 can be made of sponge, rubber, silicone, or even fluid material.

[0033] The handheld neonatal auxiliary expectorant of the present invention is designed to be hollow in the head frame 21, and the interior of the head frame 21 is filled with a buffer material 5. When the vibrating head 2 vibrates, the vibration force of the head frame 21 is dispersed and reduced by the buffering effect of the buffer material 5, so that the vibration force of the contact part that finally acts on the back of the newborn becomes uniform and gentle, and the instantaneous impact force on the back of the newborn is greatly reduced, which can not only help the newborn to expectorate, but also avoid excessive force on the back of the newborn.

[0034] Furthermore, an inner bracket 215 is provided on the inner side of the annular outer ring 211 to support the annular outer ring 211 from the inner side of the annular outer ring 211, thereby further reducing the vibration amplitude of the annular outer ring 211 and making the vibration force transmitted to the soft vibration package 220 softer; and a connection point 216 is adopted to connect with the plug interface 4. When the vibration force is transmitted from the plug interface 4 to the inner cavity, it is transmitted to the inner bracket 215 through the connection point 216 connected to the plug interface 4, and then transmitted to the upper part of the annular outer ring 211 through the inner bracket 215. It is buffered by the buffer material 5 and dispersed in all directions and gradually weakened, so that the vibration force will not be excessively concentrated near the plug interface 4, until it reaches the soft vibration package 220 that contacts the back of the newborn, and the vibration force becomes soft and uniform, with small impact force, which is more suitable for the weak back muscles of the newborn.
