Description

Technical Field

[0001] The present invention relates to the field of medical treatment instruments, and particularly to a handheld device for eliminating maternal perineal edema. Background Art

[0002] The perineum refers to all the soft tissues that close the lower opening of the pelvis, i.e., the generalized perineum. In males, it refers to the soft tissues between the root of the scrotum and the anus; in females, it refers to the soft tissues between the vaginal orifice and the anus, also known as the obstetric perineum. Perineal edema refers to a pathological phenomenon in which excessive fluid accumulates in the tissue space of the perineum, resulting in local swelling. During childbirth, the fetus will compress the perineum for a long time when passing through the birth canal, resulting in obstruction of local blood circulation and lymphatic return in the perineum, increased vascular permeability, and fluid exudation into the tissue space, thus causing edema. Episiotomy or laceration will damage the blood vessels and lymphatic vessels in the perineum, affecting the normal return of blood and lymph fluid, and will also cause edema. Due to the swelling and pain in the perineum, patients may experience difficulties in walking and restlessness in sitting, affecting daily activities. Some studies have shown that for maternal perineal edema, appropriate and correct massage may help to promote local blood circulation and lymphatic return to a certain extent, and is helpful for reducing edema. At present, traditional perineal edema massage is generally manually operated by professional physicians, midwives, postpartum recovery therapists, etc. First, paraffin oil is applied to the perineum, and after wearing sterile gloves, the perineum of the patient is massaged in a clockwise or counterclockwise circular motion with the hand. On the one hand, this method causes a heavy psychological burden on the patient, and on the other hand, it is not convenient for standardized operation. In the prior art, there are no reports on related instruments, and in perineal massage, due to the high sensitivity of the massage area and the fact that the massage effect is closely related to the massage intensity, rhythm, etc., general electric-driven massagers are not applicable.

[0025] Combined with Figures 1-4As shown, the present invention is a handheld device for eliminating maternal perineal edema, mainly used to assist in massaging and eliminating perineal edema of patients. When in use, the patient takes a supine position with knees bent for operation. As Figure 1 As shown in Figure 1 , the present invention generally includes a massage gun 1 and a bracket 2 for carrying the massage gun 1. The massage gun 1 includes a gun body 4 and a massage head 3 provided at the end of the gun body 4. The gun body 4 is used to drive the massage head 3 to perform a circumferential motion, simulating the circular massage operation of the hand.

[0026] As Figure 1 As shown, the gun body 4 of the present invention includes a gun rod 5 and a rotating shaft 6 provided on the gun rod 5. The gun rod 5 is generally made of plastic and formed by injection molding. One end of the rotating shaft 6 close to the massage head 3 is provided with an L-shaped eccentric rod 7, and the eccentric rod 7 serves as a direct driving device for the massage head 3. In addition, the present invention further includes a driving mechanism, and the rotating shaft 6 can rotate under the drive of the driving mechanism. There are many specific structural forms of the driving mechanism, as long as it can drive the rotating shaft 6 to rotate. Generally, electric forms are not recommended, which can increase the tactile feedback of the operator and facilitate the control of the massage intensity and frequency.

[0027] The massage head 3 of the present invention includes a silicone body 8 for covering the perineum and a connecting seat 9 provided on the back side of the silicone body 8. The silicone body 8 adopts a design that conforms to human engineering and can cover the entire perineal area. The connection between the massage head 3 and the gun body 4 is a detachable connection. As a whole, it can adopt a disposable design and be discarded after single use; it can also be used by wrapping a disposable protective film / sleeve, etc. Generally, in this case, since it is easy to be contaminated with lubricating paraffin oil, the silicone body 8 is selected to be made of corrosion-resistant silicone.

[0028] At the position corresponding to the rotating shaft 6 on the connecting seat 9 of the present invention, a circular rod groove 10 is provided. The eccentric rod 7 extends into the rod groove 10 and can drive the massage head 3 to perform a circumferential swing through the rotation of the rotating shaft 6. Regarding the connection between the massage head 3 and the gun body 4, in addition to the contact at the eccentric rod 7, a plurality of flexible rods 11 for inserting into the gun body 4 are uniformly provided on the connecting seat 9 on the circumferential side of the rod groove 10. The flexible rods 11 are rods with softness and elasticity. For example: the middle section of the flexible rod 11 is a rubber section. An annular connecting disk 12 is provided on the circumferential surface of the head end of the gun body 4, and a plurality of connecting pipes 13 are provided on the connecting disk 12. The flexible rods 11 are inserted into the connecting pipes 13 to form a detachable connection with the gun body 4, quickly realizing insertion and extraction. Of course, in order to ensure the tightness of the connection, there is usually a certain interference after insertion to avoid detachment.

[0029] When driving the rotating shaft 6, an optional method is as follows: The driving mechanism includes a pinch rod 14 arranged below the gun barrel 5, and the head end of the pinch rod 14 is hinged to a hinge seat 15 in the middle section of the gun barrel 5. A sliding seat 16 capable of sliding along the length direction of the gun barrel 5 is arranged on the bottom surface of the gun barrel 5. To ensure the stability of the sliding seat 16 moving on the gun barrel 5, a chute 19 extending along the length direction of the gun barrel 5 and having a T-shaped cross-section is arranged on the bottom surface of the gun barrel 5, and the sliding seat 16 is clamped in the chute 19 to form a sliding fit with the gun barrel 5.

[0030] The sliding seat 16 of the present invention is sleeved outside the rotating shaft 6 and forms a threaded fit with the rotating shaft 6. A swing rod 17 is arranged between the middle section of the sliding seat 16 and the pinch rod 14, and both ends of the swing rod 17 are hinged to the sliding seat 16 and the pinch rod 14 respectively. In this way, when the pinch rod 14 is pinched, the sliding seat 16 is driven by the swing rod 17 to move along the rotating shaft 6, thereby driving the rotating shaft 6 that forms a threaded fit with it to rotate. In one pinch and release stroke, the sliding seat 16 completes a reciprocating motion. At this time, in order to facilitate the reset of the swing rod 17, a return spring 18 for driving the swing rod 17 to reset is also arranged between the swing rod 17 and the hinge seat 15. A finger ring 0 for the user's finger to insert can also be arranged at the bottom of the pinch rod 14.

[0031] However, in this driving method, since the rotating shaft 6 has a forward and backward rotation in one pinch and release stroke, there is a certain difference from the required unidirectional circumferential massage, which has an adverse effect on the elimination of edema. Therefore, in order to ensure that the rotating shaft 6 always rotates in one direction as required, a better method of the present invention is:

[0032] As Figure 2 shown in

[0033] One end of the sliding shaft 22 close to the connecting shaft 21 is provided with a square plug rod 24. The connecting shaft 21 is provided with a jack 25 that matches the plug rod 24. The plug rod 24 extends into the jack 25 and forms a sliding fit with the connecting shaft 21. Pushing the plug rod 24 can drive the sliding shaft 22 to move, thereby changing its mating position with the connecting frame 23. One end of the connecting shaft 21 far from the sliding shaft 22 is provided with a reversing knob 26 that forms a threaded fit with the connecting shaft 21. One end of the reversing knob 26 is connected to the end of the plug rod 24 through a rotary joint 27. By rotating the reversing knob 26, the plug rod 24 is driven to move, and then the sliding shaft 22 is driven. Two driving ratchets 28 are arranged side by side on the sliding shaft 22, as Figure 3 and 4 shown. One side of the tooth of the driving ratchet 28 is an arc-shaped tooth back 29, and the other side is a straight-line abutting edge 30. The tooth backs 29 of the two driving ratchets 28 face in opposite directions. The present invention realizes controllable one-way drive through the contact between the connecting frame 23 and different driving ratchets 28. For example: when contacting the first driving ratchet 28, as Figure 3 shown, it can only rotate counterclockwise; when contacting the second driving ratchet 28, it can only rotate clockwise, as Figure 4 shown. And the drive is realized by selecting a section of the reciprocating stroke of the sliding seat 16 on the rotating shaft 6.

[0034] On this basis, the connecting frame 23 includes an L-shaped frame body 31 arranged on the upper side of the connecting shaft 21 and a transmission pin 32 arranged on the frame body 31. One L-shaped side of the frame body 31 is connected to the rotating shaft 6, and the bottom of the other side is provided with two vertical rods. Vertical strip-shaped holes 33 are arranged on the vertical rods. The end of the transmission pin 32 is provided with a chuck 34 and is clamped in the strip-shaped hole 33 through the chuck 34 to form a vertical sliding fit with the vertical rod. As Figure 3 and 4 shown, the transmission pin 32 can be pushed up by the tooth back 29, but when released from the abutting edge 30, it can also push the driving ratchet 28.

[0035] Based on the above structure, its working mode, for example: assuming that the state of the sliding shaft 22 is as Figure 2 shown, and combined with Figure 1 shown, when the sliding seat 16 is driven to the right, the rotating shaft 6 rotates clockwise. At this time, the rotation of the rotating shaft 6 cannot be transmitted to the sliding shaft 22; when the sliding seat 16 returns to the left, the rotating shaft 6 rotates counterclockwise. At this time, it can transmit power to the corresponding driving ratchet 28. That is to say, in this structure, one direction of movement of the sliding seat 16 is selected as the effective driving stroke. It can be understood that when the adjusting knob 26 is adjusted, another effective driving stroke can be correspondingly selected. By controlling the pinching speed, the operator of the present invention can control the strength and frequency.

[0036] In order to improve the labor-saving property of use and avoid the suspended operation during long-term use, a leaning seat 35 is provided at the bottom of the commutation cavity 20 of the present invention, and a hemispherical groove is provided on the bottom surface of the leaning seat 35. A ball head 36 matched with the groove is provided on the bracket 2. The groove and the ball head 36 can not only play a role in adjusting the orientation, but also play a role in supporting. On this basis, in order to adjust the position and height of the ball head 36 and ensure the stability of the installation of the bracket 2. The bracket 2 of the present invention includes a rubber diaphragm 37. The thickness of the rubber diaphragm 37 is generally about 2MM, and it has a large friction force and is convenient for placement. An adjustment groove 38 is provided on the upper surface of the rubber diaphragm 37. A sliding seat 39 that forms a sliding fit with the adjustment groove 38 is provided in the adjustment groove 38. The sliding seat 39 is locked with the adjustment groove 38 by bolts, and the front and rear positions of other components carried thereon can be adjusted (that is, Figure 1 left and right in the figure). A first support arm 40 is provided at the top of the sliding seat 39. The upper end of the first support arm 40 is hinged to the lower end of the second support arm 41, and a locking knob is provided at the hinge position. A ball head 36 is provided at the upper end of the second support arm 41.
