Abstract
The invention discloses a silica gel blood driving tape which has a good blood driving effect, can be used for comprehensively and effectively disinfecting and can be repeatedly used and a preparation method thereof. The preparation method comprises the following steps: (1) taking methyl vinyl silicon rubber as base rubber; taking silicon dioxide powder as a filling agent to reinforce; heating, pressurizing, banburying and mixing, wherein 30-60 parts of the methyl vinyl silicon rubber and 40-70 parts of the silicon dioxide powder are used; (2) adding 0.5-3 parts of a platinum vulcanizing agent, and primarily extruding and shaping by a high-pressure screw rod extruder; and (3) baking at high temperature and carrying out a cross-linking reaction to shape the product into a silica gel tape body (1), wherein the silica gel tape body (1) is provided with a plurality of anti-slipping stripes (2) and wave lines (3). The silica gel blood driving tape can be applicable to the field of medical blood driving equipment.
Description
Technical field
The present invention relates to a kind of silica gel Esmarch's bandage and preparation method thereof.
Background technology
Nowadays, in the surgical operation of extremity, must apply to and drive blood, hemostatic technique to reduce the amount of bleeding of patient in operation process, reduce simultaneously hemorrhage also make surgical field of view more clear be conducive to perform the operation smooth enforcement.And Esmarch's bandage is exactly drive the same aid indispensable in blood technology.
Had in people's bicycle that tire is as driving blood instrument, its main component is natural rubber in the past.By the impact on physical properties of material, natural rubber after experience medical apparatus and instruments standard high temperature sterilization soon aging, sticky glutinous cannot continuation use, and the folded part of the Esmarch's bandage of this kind of flat surface does not almost have space, so that can not pasteurised completely effectively; In addition, also there is people with Elastic bandage as driving blood instrument, but be subject to the impact of its elastic force, drive blood less effective.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provide a kind of drive blood effective, to sterilize comprehensively and effectively and can the silica gel Esmarch's bandage and preparation method thereof of Reusability.
The technical scheme that a kind of silica gel of the present invention Esmarch's bandage adopts is: described silica gel Esmarch's bandage comprises silica gel belt body and is arranged on some anti-skidding stripeds at least one surface of described silica gel belt body, and described some anti-skidding stripeds are arranged along described silicone band body length direction and convex.
The middle body of described silica gel belt body is provided with ripple glaze, and the wave direction of described ripple glaze is perpendicular to the length direction of described silica gel belt body.
The width of described silica gel belt body is 10-15 centimetre.
The technical scheme that the preparation method of a kind of silica gel Esmarch's bandage of the present invention adopts is: it comprises the following steps:
1. using methyl vinyl silicone rubber as base glue, coordinate silicon dioxide powder as filler reinforcement, through temperature-pressure banburying mixing, wherein, described methyl vinyl silicone rubber is 30 ~ 60 parts, and described silicon dioxide powder is 40 ~ 70 parts;
2. after adding the platinum vulcanizing agent of 0.5 ~ 3 part, again through the preliminary extrusioning shaping of high pressure screw extruder, wherein, the mould that described high pressure screw extruder adopts comprises mold and is arranged on extrusion that described mold centre is arc shaped and is positioned at several micro-connected in stars of described extrusion;
3. carry out cross-linking reaction by high-temperature baking thus realize product approval becoming silica gel belt body (1).
Described step 2. in, the silica gel belt body middle body extruded by described extrusion is with ripple glaze, and the wave direction of described ripple glaze is perpendicular to the length direction of described silica gel belt body, and some the anti-skidding stripeds convex along described silicone band body length direction.
The invention has the beneficial effects as follows: comprise silica gel belt body due to described silica gel Esmarch's bandage and arrange and some convex anti-skidding stripeds along described silicone band body length direction, Esmarch's bandage adopts silica gel material to make, can high temperature resistant and Reusability, and good springiness, and the surface of silica gel belt body is provided with some anti-skidding strias, so enable tape body effectively prevent from skidding, make to drive blood effect better to be ensured, and when the sterilization that is folded, all space can be left between each fold plane, enable belt body more thorough when sterilizing, so the present invention to drive blood effective, to sterilize comprehensively and effectively and can Reusability.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of silica gel Esmarch's bandage;
Fig. 2 is the structural representation widening silicone band extruding machine mold.
Detailed description of the invention
As shown in Figure 1, some the anti-skidding stripeds 2 that silica gel Esmarch's bandage of the present invention comprises silica gel belt body 1 and is arranged at least one surface of described silica gel belt body 1, described some anti-skidding stripeds 2 to be arranged and convex along described silica gel belt body 1 length direction, described some anti-skidding stripeds 2 are arranged on the upper surface of described silica gel belt body 1 or lower surface or two sides and all arrange, described some anti-skidding stripeds 2 can prevent from the need of described silica gel belt body 1 and user from driving producing between blood position skidding and leaving gap, can ensure in disinfecting process, gas flows through along gap and can pasteurised completely.
The central part branch of described silica gel belt body 1 is provided with ripple glaze 3, and the wave direction of described ripple glaze 3 is perpendicular to the length direction of described silica gel belt body 1.Described silica gel belt body 1 be folded carry out high-temperature sterilization time, described ripple glaze 3 can make to interspace between each fold plane of described silica gel belt body 1, can carry out high-temperature sterilization more up hill and dale like this to described silica gel belt body 1.
The length of described silica gel belt body 1 is greater than two meters and its width is not less than 10 centimetres, and what this makes it possible to improve described silica gel belt body 1 drives blood effect, preferably adopts 10-15cm.
As shown in Figure 2, one widens silicone band extruding machine mold, it comprises mold 4, the centre of described mold 4 is provided with the silicone band extrusion 5 in arc shaped, the chord length of described silicone band extrusion 5 is less than the diameter of described mold 4 and the arc length of described silicone band extrusion 5 is not less than ten centimetres, thus described in widen silicone band extruding machine mold and can extrude the wider silicone band of width when not changing original mould size.
