Description
Technical field
This utility model relates to medical instruments field, is in particular a kind of Inflatable negative-pressure drainage ball.
Background technology
It is deficient that Present Domestic is applicable to military individual soldier's medical aid armarium, and negative pressure drainage apparatus and this different conventional medical apparatus and instruments of respiration ball of being particularly applicable to individual soldier's medical aid still do not exist at present.Closed-type negative-pressure drain is the drainage method medically generally using, can particularly for the soldier of the wound of being fought, carry out as early as possible surgical drainage has great meaning for the battlefield survival rate that improves soldier, and then existing negative pressure drainage apparatus all can not meet the demand in battlefield.The principle that the negative pressure drainage napiform root that medical field adopts at present produces according to its negative pressure is broadly divided into two classes:
1. the first kind is to have utilized the elastic recovery properties of material to form negative pressure such as having compared with the rigid plastics of strong elasticity or silica gel etc., during use, before this pressing of drainage ball squeezed out to spheroid outward by spheroid inner air and then utilized the elastic recovery properties of material to make the inner negative-pressure vacuum that forms of drain spheroid, for example current modal Lantern negative pressure drainage ball or ball type drainage ball a kind of negative pressure drainage ball as disclosed in CN2013207133838 and the disposable depression drainage device of the disclosed a kind of Improvement type of CN2011103082353, yet the material that these drainage equipments adopt is conventionally heavier and can not compress folding causing and carry inconvenience, if meanwhile this class drainage equipment is used the comparatively frivolous material of quality instead and is made and be difficult to again reach needed elastic-restoring force, thereby above-mentioned shortcoming cannot be replaced and be solved by material, secondly, the elastic-restoring force of these materials and can the less negative pressure insufficient pressure that causes of deformation degree.
And the most basic requirement of medical apparatus and instruments fight adopting be light, be easy to carry about with one, preferably can one-object-many-purposes to save space, thereby above-described drainage equipment can not meet above requirement completely.
2. Equations of The Second Kind is to rely on evacuation apparatus the inner evacuation of drainage ball is formed to negative-pressure vacuum, the negative pressure drainage ball of this class need adopt elasticity and the lower hard material of deformation degree to make, the negative pressure drainage ball of this class compares with first kind drainage ball that its portability is lower, quality is larger, simultaneously it also needs to rely on extra evacuation apparatus equipment and could use, therefore the drainage ball of this class adopts the basic demand gap of medical apparatus and instruments huger with fighting, and also cannot be competent at the needs of fight of army.
Meanwhile, the respiration ball medically adopting is at present similar to above-mentioned first kind drainage ball principle, and its existing shortcoming is also identical, still can not meet the requirement of military medical apparatus and instruments.
Summary of the invention
The purpose of this utility model is: a kind of defect described in background technology that overcomes is provided, can meet fight of army demand, can fold compression easy to carry, negative pressure pressure is large, has a kind of Inflatable negative-pressure drainage ball of negative pressure drainage ball and respiration ball function concurrently simultaneously.
This utility model is achieved through the following technical solutions: it comprises vacuum cavity this utility model, and the outer wall of vacuum cavity is provided with the first joint being tightly connected with vacuum cavity, and the first joint is communicated with vacuum cavity inner chamber;
Vacuum cavity outer surface is covered with the Pneumatic support that can form three-dimensional shape after inflation, and Pneumatic support is covered in the outer surface of vacuum cavity and forms an integral body.
Compared with technology before, the beneficial effects of the utility model are:
1, the negative-pressure vacuum of negative pressure spheroid inside is to form after negative pressure spheroid being drawn into American football shape by the Pneumatic support after inflation, do not need to rely on outside evacuation apparatus or the elastic-restoring force of material self, thereby this utility model can be broken away from the constraint in traditional drainage device material, adopt frivolous and be easy to compress folding material as the light plastic making of quality softness, thereby this utility model can fold compression and the demand that meets fight of army easy to carry.
2, after the inflation of employing Pneumatic support, after this mode of bend tension negative pressure ball body formation negative-pressure vacuum, increased widely and pressed the pressure of vacuum and the volume of negative pressure spheroid also can expand according to real needs.
3, this utility model arranges check valve and after draining connector place connects respirator adaptor, can be used as the use of medical respiration ball at front end or the tail end of liquid inlet joint and draining connector, realizes one-object-many-purposes.
