Description
Technical field
This utility model relates to technical field of medical instruments, and particularly a kind of funnel chest is corrected vacuum cup.
Background technology
Funnel chest is a kind of depressed deformity of thorax, patient chest inwardly backward depression, form one resemble funnel shape region, hole, be medically called funnel chest.
Suffers from the child of funnel chest, correct funnel chest if select negative pressure device, first pressure wants enough, its less important long periods of wear (being about 3 years most), enough pressure just can pick up depression position, and under the suction function of similar cup, this position skin easily plays erythema, occurs the phenomenons such as livid purple, the surrounding of negative pressure device produces larger pressure to breastbone, brings secondary insult to wearer.
The existing utility model patent of prior art (application number CN200920033980) is for negative pressure traction orthosis, possible in principle, and actual use do not possess operability.Its only consider patient cave in position form one enough strong, the negative pressuren zone enough sealing, just can drink up the position of caving in.But there is following drawback:
In order to form a stronger negative pressure region, original device adopts the design of hard material fitted seal circle, has only considered negative pressure intensity and sealing, does not consider the impression of wearing of user.When powerful negative pressure produces, negative pressure device can be oppressed skeleton around, brings secondary insult, and wearer's pain sense of discomfort is strong, and child's user also can produce conflict the psychology of fear, wears for a long time and is difficult to realize, and skeleton rectification effect is difficult to reach.
Be in for a long time the skin under airtight negative pressure, easily occurred erythema, " by the cup " phenomenon such as livid purple, if can not find in time and extract sucker, can skin generation be damaged, patient cannot life-time service.
Utility model content
For the defect existing in prior art, the purpose of this utility model is to provide a kind of funnel chest and corrects vacuum cup.
This utility model adopts following technical scheme:
A kind of funnel chest is corrected vacuum cup, comprises sucker, air bag, form, air conduit, intake valve and one-way exhaust valve;
Described sucker is taper shape or hemispherical, and has a cavity; In order to adapt to breast type;
The wall thickness of described sucker increases to slot end gradually from wide mouth end; The outer surface of described cavity is the cambered surface of evagination; First this design has increased the support force of sucker, make sucker can bear enough large pressure, secondly this design has increased the cavity outer surface of sucker and the contact area of chest, suction is larger, contact area is larger, pressure can be dispersed in a larger area, avoid secondary insult, improve the comfort level of wearing;
Described form card and the slot end that is connected in described sucker, improved sealing.
On the basis of such scheme, described sucker is medical soft material, is the part that mainly contacts chest, is difficult for allergy, comfortable wearing; Described form is hard transparent material, in use observes the variation of sucker inner skin for user, extremely can find in time and stop or weakening negative pressure once produce, and avoids skin to produce injury.
Described hard transparent material can be selected from acrylic, PVC etc.;
The soft material of described sucker can be selected from medical grade rubber, medical silica-gel etc., can effectively avoid the generation of skin allergy.
The beneficial effects of the utility model are:
Simple in structure, reasonable in design, when use, avoid secondary insult, improve the comfort level of wearing, arranging of transparent window can be observed the variation of sucker inner skin at any time, easy to use.
Brief description of the drawings
This utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of sucker described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Embodiment 1
As depicted in figs. 1 and 2, a kind of funnel chest described in the utility model is corrected vacuum cup, comprises sucker 1, air bag 2, form 3, air conduit 4, intake valve 5 and one-way exhaust valve 6; Described sucker 1 is taper shape or hemispherical, and has a cavity (7); In order to adapt to chest shape; The wall thickness of described sucker 1 increases to slot end gradually from wide mouth end; As shown in Figure 2, the cambered surface that the outer surface of described cavity 7 is evagination; This design has increased the contact area with chest, and when use, suction is larger, and contact area is larger, pressure can be dispersed in a larger area, has avoided the secondary insult to chest, has improved the comfort level of wearing;
Described form 3 is adhered to the slot end of described sucker 1, is easy to ensure sealing; Hard material does not expose, and improves comfort level.
Preferably, described form 3 is hard transparent material; Described hard transparent material can be selected from acrylic, PVC etc.; In use observe the variation of sucker inner skin for user, extremely can find in time and stop or weakening negative pressure once produce, improve the level of comfort of wearing;
Preferred described sucker 1 is soft material, and the soft material of described sucker can be selected from medical grade rubber, medical silica-gel etc., can effectively avoid the generation of skin allergy.
Specific embodiment of the utility model is only the object for exemplary illustration; it limits protection scope of the present invention never in any form; those skilled in the art can be improved according to the above description or be converted, and all these improvement and conversion all should belong to the protection domain of this utility model claims.
