Abstract
The utility model relates to a controlling device for skin expansion. A peristaltic pump is communicated with a skin expansion instrument container through a pipeline, the signal output end of a controller is connected with the signal input end of the peristaltic pump, a detection probe of a detection sensor is placed in the container, and the signal output end of the detection probe is connected with the signal input end of the controller. The utility model provides the controlling device for skin expansion, which has the advantages that the continuous and fluctuant pressure can be controlled for carrying out expansion on soft tissue and skin, the maximum tissue expansion can be realized, and the pain and the tissue necrosis of patients can be avoided.
Description
Technical field
This utility model relates to a kind of control device of skin dilator.
Background technology
The dermal tissues device is that American physician draws Du to cut down (Randovan) at first application in 1976.It is a kind of blister cavities type satchel made from silica gel, and it can divide three parts: utricule, conduit and injection kettle.During use, it is subcutaneous that the doctor imbeds patient to tissue expander, and scalp down or in the muscle gap, wound just can heal about about two weeks.At this moment, begin to inject normal saline, with the blister cavities expansion of progressively expanding through the injection kettle.Each liquid that injects blister cavities is about the 10-15% of specified volume.Every injection in 4-5 days once, continuous several times is injected, and the skin histology up to the dilator top expands the expection area to, generally needs through 6 weeks.At this moment the doctor just can carry out second phase operation, also is main operation, and the skin that utilizes expansion to increase is repaired contiguous tissue defect, repairs deformity.This method neither produces new supply area vestige, and advantages such as operation is easy, wound is less, evident in efficacy are arranged again.The shortcoming of skin soft-tissue expansion is that operation needs gradation to carry out, treatment time is long, and will be by the water filling of manually repeatedly puncturing, operation efficient is low, sometimes be difficult to grasp water injection rate by artificial recharge, can not adjust corresponding water injection rate according to the pressure and the volume of container, when water filling, can occur the too much phenomenon of water filling like this, cause the cutaneous necrosis possibility thereby skin is produced bigger compressing.
The utility model content
This utility model is at the deficiencies in the prior art, design and develop out a kind of pressure that continues and fluctuate of can controlling soft tissue and skin are expanded, can accomplish maximum tissue expander and avoid patient's pain and the control device that is used for skin expansion of tissue necrosis.
This utility model is achieved through the following technical solutions:
A kind of control device that is used for skin expansion has in order to the peristaltic pump of power to be provided, and in order to the controller of control peristaltic pump rotating speed and flow, and forms in order to the detecting sensor of measuring vessel pressure and capacity; Described peristaltic pump is communicated with skin expansion appearance device by pipeline; The signal output part of described controller is connected with the signal input part of described peristaltic pump; The detection probe of described detecting sensor is placed in the described container, and the signal output part of detection probe is connected with described controller signals input.
This utility model moves control by utilizing controller to peristaltic pump, can carry out continual liquid or the gas of charging into to the expansion capsule that implants 24 hours every days, avoided the excessive tissue necrosis that causes of the too much pressure of disposable injection in the past, perhaps per injection is very few, prolongs the drawback of tissue expander time.Can utilize continuing of to control to greatest extent and the pressure of fluctuation is expanded soft tissue and skin, can accomplish maximum tissue expander and avoid patient's pain and tissue necrosis.Peristaltic pump has two-way equal flow volume delivery ability; Can any parts of pump not caused damage under the no liquid dry run situation; Can produce and reach 98% vacuum; Do not have valve, mechanical seal and stuffing seal, just do not have these to produce the factor of revealing and safeguarding yet; Only flexible pipe is for needing the parts of replacement, and it is very simple to change operation; Except that flexible pipe, institute's conveying products does not contact with any parts.The constantly detection numerical value of this device by checkout gear utilizes controller that the rotating speed and the pump discharge of peristaltic pump are carried out precision control, reaches then and can not cause compressing and necrosis to skin again by Rapid Expansion skin, the purpose that patient again can feels pain.
Description of drawings
Accompanying drawing is the apparatus structure sketch map.
The specific embodiment
Shown in accompanying drawing.
The control device of skin expansion has the peristaltic pump 1 in order to power to be provided, and in order to the controller 2 of control peristaltic pump 1 rotating speed and flow, and forms in order to the detecting sensor 3 of measuring vessel 5 pressure and capacity; Peristaltic pump 1 is communicated with skin expansion appearance device 5 by pipeline 4; The signal output part of controller 2 is connected with the signal input part of peristaltic pump 1; The detection probe 6 of detecting sensor 3 is placed in the container 5, and the signal output part of detection probe 6 is connected with controller 2 signal input parts.During use, the detection probe 6 of detecting sensor 3 detects pressure and the capacity in the container 5 constantly, and with the detected information transmission to controller 2, controller 2 is according to the pressure and the capacity data of current container, the rotating speed and the pump discharge of control peristaltic pump 1, can utilize continuing of to control so to greatest extent and the pressure of fluctuation is expanded soft tissue and skin, can accomplish maximum tissue expander and avoid patient's pain and tissue necrosis.
