Description

Technical Field

[0001] The utility model relates to the technical field of skin tightness measurement, in particular to a skin tightness measuring device. Background Art

[0002] Cutis laxa is manifested clinically as loose, wrinkled skin. Excessively loose skin forms pedunculated suspensions that sag due to gravity. Currently, doctors typically assess skin tightness by pinching the skin and then relying on experience to determine the degree of skin tightness or sebum separation. This is highly subjective and makes it difficult to provide clear and objective judgments. Furthermore, it can easily lead to a loss of trust in doctors, hindering their work.

[0003] In the prior art, the degree of skin suction is usually converted into an objective representation using a negative pressure device. For example, patent publication number CN112137586A discloses a semi-automatic skin elasticity detection device. Specifically, the device seals the skin with a sealing cover, then uses a positive and negative pressure gauge to measure the skin's tightness.

[0004] However, the use of a sealing cover to suction local skin in a sealed condition has the disadvantages of inaccurate measurement and strong pain for the patient. This is because the already loose skin has a certain degree of elasticity and fluidity, and the loose area of the skin cannot be confirmed before suction. Furthermore, the sealing cover is placed on the local skin. To ensure the seal, the loose skin outside the sealing cover cannot be suctioned during the suction process, which results in inaccurate measurement. In addition, the sealed local suction is not convenient for pre-confirming the approximate pressure range. Furthermore, if the suction is too strong, it will cause excessive separation of the skin and flesh, which will cause the patient's pain to be doubled.

[0005] Based on the above description, there is an urgent need for a skin tightness measuring device with high measurement accuracy and low pain. Utility Model Content

After installation and connection, the suction device 1 is started, and a ventilation gap is created inside the rod body 21 by pressing the piston assembly 3, thereby making the suction head 22, the rod body 21 and the suction device 1 connected in sequence, thereby performing preliminary debugging of the suction strength of the suction device 1. After preliminary debugging, the suction head 22 is placed above the skin for testing. The suction head 22 can contact the skin but does not apply force to press the skin, or the suction head 22 and the skin do not contact each other, so as to ensure that the loose skin can be sucked. There is no need to ensure the sealing during suction to reduce the difficulty of operation, and the loose skin can be freely stretched and flowed, thereby ensuring the accuracy of the detection, and also reducing the patient's pain through pre-debugging and avoiding local suction; according to the stable reading of the pressure gauge on the suction device 1, the difficulty of suction is characterized, and then the tightness of the skin is objectively characterized.
