DETAILED DESCRIPTION
[0022] The principles and characteristics of the present application are described below in combination with the drawings, and the examples are only used to explain the present application and are not used to limit the scope of the present application.
[0023] Embodiment: as Figure 1 , 2As shown in FIGS. 1, 2 and 3, the ultrasonic monitoring automatic negative pressure suction device of the embodiment comprises a cover 1, an ultrasonic instrument 2 and a negative pressure system. The ultrasonic instrument 2 is connected with an ultrasonic probe 21. A coupling surface 11 adapted to the detection surface of the ultrasonic probe 21 is concavely arranged in the middle region of the top of the cover 1. The detection surface of the ultrasonic probe 21 is attached to the coupling surface 11 and can rotate along the coupling surface 11. The cover 1 is provided with a liquid injection port 12, a negative pressure interface 13 and a pressure relief port 14. The negative pressure interface 13 is connected with the negative pressure system. The edge of the open end of the cover 1 is provided with a sealing structure 3. The cover 1 is used to cover the skull depression of a patient.
[0024] In the embodiment, the ultrasonic instrument 2 is a conventional ultrasonic device in clinic. The ultrasonic instrument has a three-dimensional imaging function.
[0025] In the embodiment, control valves are arranged at the liquid injection port 12 and the pressure relief port 14. After the cover 1 is injected with the medium, the valve of the liquid injection port 12 can be closed. When the negative pressure in the cover 1 is abnormal or the skull defect has been reset under the action of the negative pressure, the valve of the pressure relief port 14 can be opened to balance the pressure.
[0026] The use process is as follows:
[0027] In use, the cover 1 is covered on the skull depression of a patient (specifically, the open end of the cover 1 is attached to the scalp around the skull depression (indicated by A in the figure) to realize the attachment and sealing with the scalp through the sealing structure 3). The cover 1 completely covers the skull depression. Thus, a sealed cavity is formed between the cover 1 and the skull depression of the patient. In the resetting process, the negative pressure interface 13 is connected with the negative pressure system. Meanwhile, the cover 1 is injected with the coupling liquid through the liquid injection port 12 to ensure that the coupling liquid fills the lower part of the coupling surface 11 and the skull in the cover 1. Then, the detection surface of the ultrasonic probe 21 is attached to the coupling surface 11 on the top of the cover 1. The skull in the area where the cover 1 is located is detected by rotating the ultrasonic probe 21 attached to the coupling surface 11. The three-dimensional imaging is performed on the ultrasonic instrument 2. Meanwhile, the negative pressure system provides the negative pressure suction for the cover 1. Thus, the skull of the child in the skull depression can be sucked outwards to the predetermined state. In the suction process, the skull morphology in the cover 1 is detected in real time by the ultrasonic probe 21 and imaged. In this process, the negative pressure in the cover 1 can be adjusted according to the ultrasonic image information until the skull in the skull depression of the newborn recovers to the predetermined morphology. The overall structure is simple and reasonable. The skull depression resetting morphology can be dynamically displayed by using the ultrasonic imaging. The negative pressure size can be adjusted according to the morphology until the skull resetting reaches the predetermined morphology. The technology is non-invasive and non-radiation. The resetting effect is satisfactory. Meanwhile, the resetting negative pressure suction time can be shortened and the scalp congestion can be reduced.
[0028] As a preferred embodiment, the vertical distance between the position of the negative pressure interface 13 and the plane where the open end of the cover body 1 is located is greater than the vertical distance between the coupling surface 11 and the plane where the open end of the cover body 1 is located.
[0029] In the above embodiment, the design of the size defines that the coupling surface 11 is concave downward at the top of the cover body 1, and the distance between the coupling surface 11 and the skull is smaller than the distance between the negative pressure interface 13 and the skull, that is, the position of the negative pressure interface 13 is higher than the coupling surface 11. On the one hand, the distance between the coupling surface 11 and the skull is smaller, which is easy for the ultrasonic probe 21 to effectively detect. On the other hand, the height of the negative pressure interface 13 is higher than the coupling surface 11, which can avoid the most of the medium injected into the cover body 1 from being sucked away during the negative pressure suction process, and ensure that the area below the coupling surface 11 is always filled with coupling medium, thereby ensuring the effectiveness of the detection of the ultrasonic probe 21.
[0030] It should be noted that the cover body 1 does not need to be filled with coupling medium, and only needs to ensure that the area between the coupling surface 11 and the skull is filled with coupling medium.
[0031] In the embodiment, the design of the coupling surface 11 at least includes the following structural forms:
[0032] 1) The middle area of the top of the cover body 1 is concave to form a hemispherical surface, and the hemispherical surface constitutes the coupling surface 11.
[0033] 2) The middle area of the top of the cover body 1 is vertically concave downward to form a columnar cavity, the bottom surface of the cavity is a hemispherical surface, and the hemispherical surface constitutes the coupling surface 11.
[0034] The above two schemes can ensure that the ultrasonic probe 21 is placed and can rotate 360 degrees along the coupling surface 11 and tilt and rotate, and ensure that the ultrasonic probe 21 can effectively detect the shape change of the skull in the range of the cover body 1.
[0035] As a preferred embodiment, the sealing structure 3 is a silica gel sealing ring.
[0036] In the above embodiment, the sealing structure 3 adopts a silica gel sealing ring, so that the open end of the cover body 1 can be sealed and attached to the skull, thereby ensuring that the cover body 1 is a closed cavity during the negative pressure suction process, and leakage does not occur, thereby ensuring the effective performance of the negative pressure suction.
[0037] It should be noted that a convex ridge can be arranged on the edge of the open end of the cover body 1, and the silica gel sealing ring is a groove-shaped component, which is clamped outside the convex ridge in a cladding manner, thereby facilitating the disassembly and assembly of the silica gel sealing ring.
[0038] As a preferred embodiment, the cover body 1 is a tempered glass piece or a transparent plastic piece.
[0039] In the above embodiment, the cover body 1 is made of transparent material, which facilitates medical staff to observe the changes of the skull depression through the cover body 1.
[0040] In the embodiment, the coupling surface 11 is made of sound-transparent silica gel material. The use of sound-transparent silica gel material can effectively enable the ultrasonic probe 21 to detect.
[0041] As a preferred embodiment, the negative pressure system includes a negative pressure device 41 and a liquid collecting bottle 42. The liquid collecting bottle 42 is provided with a liquid inlet and a negative pressure port. The negative pressure device 41 is connected to the negative pressure port of the liquid collecting bottle 42 through a negative pressure pipeline. The liquid inlet of the liquid collecting bottle 42 is connected to the negative pressure interface 13 through a pipeline.
[0042] In the above embodiment, when the negative pressure device 41 is turned on, a negative pressure is formed in the negative pressure pipeline, so that the cover body 1 starts to "suck". Even if some medium enters the pipeline, it will also be collected in the liquid collecting bottle 42, avoiding the medium entering the negative pressure device 41 and causing failure.
[0043] In the embodiment, the negative pressure device 41 can be a conventional vacuum pump on the market, and the specific model can be selected flexibly according to actual use requirements.
[0044] In the embodiment, a controller 5 is further included, and a pressure monitor 43 is arranged on the negative pressure pipeline. The controller 5 is connected to the pressure monitor 43. The pressure monitor 43 detects the change of the negative pressure on the negative pressure pipeline between the liquid collecting bottle 42 and the negative pressure device 41, so as to make timely adjustment.
[0045] In the embodiment, the pressure monitor 43 can be a conventional pressure sensor or a negative pressure sensor.
[0046] In the embodiment, the controller 5 is connected to the ultrasonic instrument 2 and the negative pressure system. Specifically, the controller 5 is connected to the negative pressure device 41 (such as a vacuum pump) of the negative pressure system, so as to realize automatic control operation. Specifically, when the ultrasonic instrument 1 displays that the skull depression has been reset, the controller can control the negative pressure device 41 to stop, so as to realize automatic operation as a whole.
[0047] It should be particularly emphasized that the size of the cover body 1 in the embodiment is reasonably selected according to the size of the skull depression of the newborn, and the skull depression should be completely located in the sealing cover range of the cover body 1.
