[0034] The technical solutions provided by the embodiments of the present application will be described below with reference to the drawings.

[0035] Figures 1 to 7 The negative pressure nursing equipment 100 of at least one embodiment of the utility model is shown. Specifically, referring to Figure 1 and Figure 2 , the negative pressure nursing equipment 100 comprises: a negative pressure cavity 20, a negative pressure generator 30 and a massage body 40. The negative pressure cavity 20 defines a receiving cavity 21 inside, and has a first side end 22, the receiving cavity 21 penetrates the first side end 22 of the negative pressure cavity 20 to form a first opening 23, and the first opening 23 is used for the negative pressure part 901 to extend into the receiving cavity 21. The negative pressure generator 30 is connected with the negative pressure cavity 20, which is used for changing the air pressure in the receiving cavity 21 of the negative pressure cavity 20, adjusting the blood flow of the negative pressure part 901. The massage body 40 is arranged outside the first side end 22 of the negative pressure cavity 20 and connected with the negative pressure cavity 20. The massage body 40 is used for massaging the massaged part 902. The massaged part 902 is adjacent to the negative pressure part 901.

[0036] The negative pressure nursing device 100 of the present application is applied to the part 901 to which negative pressure is applied, and the part 901 extends into the receiving cavity 21 of the negative pressure cavity 20 from the first opening 23. The edge of the first opening 23 is in sealing abutment with the part 901 to which negative pressure is applied. When the air pressure in the receiving cavity 21 is adjusted to negative pressure by the negative pressure generator 30, a negative pressure environment is formed in the receiving cavity 21. Due to the greater air pressure on the body part of the user outside the receiving cavity 21, under the action of the air pressure difference, the blood vessels of the part 901 to which negative pressure is applied dilate in the body, the blood flow to the part 901 to which negative pressure is applied increases, so that the part 901 to which negative pressure is applied has greater blood flow, and the part 901 to which negative pressure is applied obtains more oxygen and nutrients, which helps the muscles of the part 901 to which negative pressure is applied to recover and grow. In addition, the part 902 to be massaged is adjacent to the part 901 to which negative pressure is applied, and after the part 901 to which negative pressure is applied extends into the receiving cavity 21 of the negative pressure cavity 20, the part 902 to be massaged is located at the position of the first opening 23. The massage body 40 performs a massaging action on the part 902 to be massaged, effectively increasing the massaging area of the negative pressure nursing device 100 and improving the user's experience.

[0037] Specifically, there can be various combinations between the part 901 to which negative pressure is applied and the part 902 to be massaged. In some applications, the part 901 to which negative pressure is applied is the forearm, and the part 902 to be massaged is the elbow joint. In some applications, the part 901 to which negative pressure is applied is the palm, and the part 902 to be massaged is the forearm. In some applications, the part 901 to which negative pressure is applied is the palm, and the part 902 to be massaged is the wrist joint. In some applications, the part 901 to which negative pressure is applied is the forearm, and the part 902 to be massaged is the upper arm. In some applications, the part 901 to which negative pressure is applied is the foot palm, and the part 902 to be massaged is the lower leg. In some applications, the part 901 to which negative pressure is applied is the foot palm, and the part 902 to be massaged is the lower leg.

[0038] Specifically, the massage body 40 produces a massaging action on the part 902 to be massaged by one or more massaging modes. The massage body 40 can produce a massaging action on the part 902 to be massaged by vibration, swinging, sliding, clamping, or other movement forms.

[0039] In some embodiments, the massage body 40 can be in contact with one side of the part 902 to be massaged. In other embodiments, two massage bodies 40 can be in contact with opposite sides of the part 902 to be massaged. In yet other embodiments, several massage bodies 40 can be in contact with the peripheral side of the part 902 to be massaged.

[0040] In some embodiments, in combination with Figure 2 and Figure 3As shown, the negative pressure nursing device 100 further comprises a vibrator 43, which is used to transmit vibration to the massage body 40. When the massage body 40 contacts the massage site 902, the massage body 40 can transmit vibration to the massage site 902, so as to provide a vibration massage mode for the massage site 902.

[0041] In some embodiments, in combination with Figure 3 and Figure 4 As shown, the massage body 40 comprises a first contact part 41 and a connecting part 42. The first contact part 41 is arranged outside the first side end 22 of the negative pressure cavity 20. Specifically, the first contact part 41 is used to contact the massage site 902 to generate a massage effect on the massage site 902. The connecting part 42 is connected between the negative pressure cavity 20 and the first contact part 41, so that the first contact part 41 is in a stable position relative to the negative pressure cavity 20. Specifically, the connecting part 42 has flexibility. When the massage site 902 is in extrusion contact with the first contact part 41, the connecting part 42 can be deformed, thereby limiting the extrusion force between the first contact part 41 and the massage site 902, and avoiding excessive pressure on the massage site 902. Specifically, in the case that the connecting part 42 has a certain shape stability, the massage site 902 can be supported on the first contact part 41.

[0042] In some embodiments, in combination with Figure 3 As shown, the vibrator 43 is arranged in the first contact part 41. Since the first contact part 41 directly contacts the massage site 902, the transmission path of the vibration energy is reduced, and the vibration feeling of the massage site 902 is improved. Specifically, the vibrator 43 is a vibration motor or other device capable of generating vibration.

[0043] In some embodiments, in combination with Figure 3 and Figure 4 As shown, the massage body 40 further comprises at least one second contact part 44 connected to the first contact part 41. Specifically, since the second contact part 44 is connected to the first contact part 41, the second contact part 44 can simultaneously contact the massage site 902, thereby increasing the contact area between the massage body 40 and the massage site 902, and the massage body 40 can generate a larger range of massage effect.

[0044] Further, the at least one second contact part 44 encloses a space for accommodating the massage site 902. Specifically, a single second contact part 44 can be annular or arc-shaped, thereby forming a space capable of accommodating the massage site 902. Specifically, at least two second contact parts 44 can be arranged on opposite sides of the first contact part 41, and a space capable of accommodating the massage site 902 is formed between the two opposite second contact parts 44. More specifically, in combination with Figure 4As shown, the second contact portion 44 is arc-shaped and sheet-shaped, so as to bear on the massaged part 902 and effectively control the volume of the massaging body 40. More specifically, the relative direction between the two second contact portions 44 is perpendicular to the direction in which the negative pressure part 901 extends into the accommodating cavity 21.

[0045] In some embodiments, the second contact portion 44 is integrally connected to the first contact portion 41, so as to improve the connection stability between the second contact portion 44 and the first contact portion 41 and simplify the assembly of the massaging body 40.

[0046] In some embodiments, the massaging body 40 can slide away from or close to the negative pressure cavity 20 under the action of the driving device, so as to provide a kneading massage effect on the massaged part 902.

[0047] In some embodiments, the negative pressure care device 100 further comprises a swing driving mechanism coupled to the at least two second contact portions 44, and the swing driving mechanism is configured to drive the at least two second contact portions 44 to swing towards or away from each other. Specifically, when the two second contact portions 44 swing towards each other, the distance between the two second contact portions 44 decreases, and when the two second contact portions 44 swing away from each other, the distance between the two second contact portions 44 increases, so as to provide a kneading massage effect on the massaged part 902. Specifically, the swing driving mechanism can comprise a driving motor and a transmission member. The output shaft of the driving motor drives the two second contact portions 44 to swing relative to each other through the transmission member. More specifically, the transmission member comprises a transmission rod and a gear, and the number or specific cooperation form of the transmission rod or the gear can be set according to the swing form of the second contact portion 44.

[0048] In some other embodiments, the second contact portion 44 can also swing away from and close to the negative pressure cavity 20.

[0049] In some embodiments, the at least one second contact portion 44 is provided with a vibrator. Since the second contact portion 44 can directly contact the massaged part 902, the transmission path of the vibration energy is reduced, and the vibration feeling of the massaged part 902 is improved.

[0050] In some embodiments, the first contact portion 41 and the second contact portion 44 are respectively provided with a vibrator.

[0051] In some embodiments, in combination with Figures 5 to 7As shown, the negative pressure nursing device 100 further comprises a first pipeline 31. The negative pressure generator 30 is connected to the accommodation cavity 21 through the first pipeline 31. Specifically, the negative pressure generator 30 can be connected to the negative pressure cavity 20 through the first pipeline 31. More specifically, the negative pressure cavity 20 is provided with a first through hole 71, and the accommodation cavity 21 is connected to the first pipeline 31 through the first through hole 71. When the negative pressure generator 30 is working, the negative pressure generator 30 can draw out the gas in the accommodation cavity 21 through the first pipeline 31 and discharge the gas to the outside of the negative pressure nursing device 100 through the first pipeline 31.

[0052] In some embodiments, the negative pressure nursing device 100 further comprises a second pipeline 32 and a valve 33. Figures 5 to 7 As shown, the negative pressure nursing device 100 further comprises a second pipeline 32 and a valve 33. The second pipeline 32 is connected to the accommodation cavity 21. The valve 33 is connected in series to the second pipeline 32, and the valve 33 is used to control the opening and closing of the second pipeline 32. Specifically, the valve 33 has an open state and a closed state. When the negative pressure nursing device 100 is in use, the valve 33 is in the closed state, and at the same time, the negative pressure generator 30 draws out the gas in the accommodation cavity 21, so that the gas pressure in the accommodation cavity 21 gradually decreases. When the use of the negative pressure nursing device 100 is completed, the negative pressure generator 30 stops working, and at the same time, the valve 33 is switched to the open state. The external gas quickly flows into the accommodation cavity 21 through the second pipeline 32, so that the accommodation cavity 21 can quickly recover to normal pressure, and the part 901 to which the negative pressure is applied can be easily withdrawn from the accommodation cavity 21. Specifically, the valve 33 can be connected to the negative pressure cavity 20 through the second pipeline 32. The accommodation cavity 21 is connected to the second pipeline 32 through a second through hole 72.

[0053] In some embodiments, the valve 33 is an electromagnetic valve. In other embodiments, the state switching of the valve 33 is manually operated.

[0054] In some embodiments, the negative pressure nursing device 100 further comprises a second pipeline 32 and a valve 33. Figure 6 and Figure 7 As shown, the negative pressure nursing device 100 further comprises a power supply 34. The negative pressure generator 30 comprises a vacuum pump and a driving source. The driving source is electrically connected to the power supply 34. Specifically, the power supply 34 outputs electric current to the driving source of the negative pressure generator 30, so that the airflow action structure in the vacuum pump operates, thereby drawing out the gas in the accommodation cavity 21. Specifically, the negative pressure generator 30 is an electric vacuum pump. Specifically, the power supply 34 is a lithium battery, a capacitor or other devices capable of providing electric energy for the driving source. Specifically, the driving source is an electric motor.

[0055] In other embodiments, the negative pressure generator 30 can also be a pusher or a press-type air pump.

[0056] Specifically, the negative pressure generator 30 has a structure for preventing backflow of gas. When the negative pressure generator 30 stops running, external gas can be prevented from flowing back into the accommodation cavity 21 through the negative pressure generator 30.

[0057] In some embodiments, as shown in Figure 6 and Figure 7 The negative pressure therapy device 100 further comprises a controller 35 and a sensor. The sensor is configured to detect the pressure in the accommodation cavity 21, and the controller 35 is configured to control the operation of the vacuum pump according to the detection result of the sensor. Specifically, when the detection result reaches an upper limit value of the pressure, the controller 35 controls the vacuum pump to stop operating. When the detection result is lower than a lower limit value of the pressure, the controller 35 controls the vacuum pump to start operating, so that the negative pressure in the accommodation cavity 21 can be automatically maintained within a stable range, avoiding discomfort caused by excessive negative pressure and affecting the effect caused by insufficient negative pressure. Further, the controller 35 is further configured to control the state switching of the valve 33.

[0058] Specifically, the power supply 34 outputs current to the vibrator 43. The vibrator 43 operates under the control of the controller 35.

[0059] In some embodiments, as shown in Figure 3 The negative pressure therapy device 100 further comprises an end cover 60 covering the first opening 23, and the end cover 60 and the negative pressure cavity 20 jointly form the boundary of the accommodation cavity 21. The end cover 60 has flexibility. The end cover 60 is provided with a hole 61 for the part to be applied with negative pressure 901 to pass through. Specifically, when the part to be applied with negative pressure 901 passes through the hole 61, the edge of the hole 61 tightly abuts the outer circumferential side of the part to be applied with negative pressure 901, so that the accommodation cavity 21 can maintain airtightness.

[0060] In some embodiments, as shown in Figure 3 and Figure 5 The negative pressure therapy device 100 further comprises a base shell 70 connected to the negative pressure cavity 20. The base shell 70 and the negative pressure cavity 20 jointly form the accommodation cavity 21. The negative pressure generator 30 is accommodated in the base shell 70. Specifically, the base shell 70 plays a role of mounting and protecting the negative pressure generator 30. At the same time, the base shell 70 and the negative pressure cavity 20 jointly form the accommodation cavity 21, which is conducive to simplifying the structure of the negative pressure therapy device 100.

[0061] Further, as shown in Figure 2 and Figure 3 Part of the base shell 70 is accommodated in the negative pressure cavity 20, so that the volume of the negative pressure therapy device 100 can be properly controlled without affecting the accommodation space of the part to be applied with negative pressure 901, and the compactness of the negative pressure therapy device 100 is improved.

[0062] In some embodiments, the vibrator 43 is accommodated in the base shell 70 and transmits vibration to the first contact part 41 through a component having a certain rigidity.

[0063] Specifically, as shown in Figure 2As shown, the connecting portion 42 is connected between the base 70 and the first contact portion 41. Further, the negative pressure cavity 20 has a second side end 24 opposite to the first side end 22.
