Description
Technical field
The present invention relates to medical operation dressing technical field, more particularly to a kind of high water absorbing ability string spun lacing nonwoven
Operation dressing and its application.
Background technology
In surgical procedure, disposable absorbent dressing is used to absorb blood and wound debridement.Water suction for hospital surgical
Property dressing has two kinds of main Types：
(a) operation towel (also referred to as laparotomy sponge) of laparotomy ventrotomy, for the laparotomy ventrotomy of open otch, largely
Blood and exudate will need to be absorbed with laparotomy sponge.Laparotomy sponge is typically made of cotton weaving yarn cloth, with it is a piece of it is short not
The barium piece of radioparent is sewn on the side of laparotomy sponge.If laparotomy sponge is unexpectedly stayed in patient body, it is possible to logical
X-ray detection is crossed to track.This radiopaque barium piece is one containing the PVC rubber that about 60% barium sulfate is accounted in weight
Bar.Laparotomy sponge must flexible relative and pliable so that it can be easily pushed into body between Different Organs
To absorb blood in small chamber or gap.In addition, laparotomy sponge needs have relatively high stretching on warp-wise and weft direction
Intensity, so will not be damaged during blood is absorbed using it or be thinned out.Gauze laparotomy sponge has different sizes, such as
45cm × 45cm, 30cm × 30cm, 15cm × 60cm etc., wherein most are that 4 layers of gauze alignment stack and around side
Edge is stitched together.Property and position of the selection of laparotomy sponge size depending on laparotomy ventrotomy.Because the cloth of gauze has
Fine hair and yarn and thread head, the requirement of gauze laparotomy sponge are washed and dried in advance before packing.Laparotomy sponge generally every 5 with
Paper band bundles, with advanced medico paper or plastic film wrapped, be encapsulated into it is subject to sterilization in sterilization packaging bag or pallet, then
For performing the operation.
(b) dressing sheet with X-ray tracking line, for smaller outer otchIt is lowInvasive procedures.Blood from this operation and
The amount of exudate is far below laparotomy ventrotomy.Therefore, the size of dressing sheet is much smaller compared with laparotomy sponge.Band X-ray is followed the trail of
The most common type of line dressing sheet is 10cm × 10cm, 12 layers or 16 layers, is made up of cotton weaving yarn cloth.Radiopaque material leads to
It is often the PVC rubber covered wires that about 60% barium sulfate is accounted for containing weight, is generally hot pressed and is attached on gauze.Except absorb blood it
Outside, X-ray tracking line dressing sheet is also commonly used for debridement wound.Therefore, dressing sheet needs all to have on warp-wise and broadwise both direction
There is relatively high tensile strength, so that dressing sheet will not die down during whole use.In addition, for wound debridement application
Dressing sheet can not be too soft.X-ray tracking line dressing sheet every ten is bundled with paper band, is sealed in sterilizing bag or pallet and is treated
Sterilizing, is subsequently used for performing the operation.
It should also be noted that a major issue be, using laparotomy sponge or X-ray tracking line dressing sheet can anticipate after surgery
Other places stays in patient body.In general, dressing sheet is white, but Post operation, and the dressing sheet of blood immersion is difficult in patient
Find in vivo.Past many patents are used for various computer count systems and different detection devices, it is intended to reduce in disease
The chance of laparotomy sponge or X-ray tracking line dressing sheet is left in human body.However, these patented number systems and detection
Equipment is not 100% safety, because X-ray tracking line/barium piece is still required to be attached on per a piece of dressing sheet.
At present, two kinds of operation water imbibition dressing is generally all made up of cotton weaving yarn cloth, although making us with many
Discontented characteristic, especially contacted with the trimming of gauze and for manufacturing the height labour during gauze dressing as reason institute
The caused fine hair often found in gauze, yarn and thread head and other pollution problems.Because mesh is perforate thus gauze
Water absorption is not high, it means that needs a large amount of gauze dressings to absorb blood and other exudates.Further, since intensive labor companion
With persistently escalating for Chinese and other most of developing countries for producing gauze dressings in the world wage levels, yarn
The manufacturing cost trend of cloth dressing is constantly rising.
Johson ＆ Johnson was once attempted in phase late 1980s with 70% viscose glue and 30% terylene (weight ratio) mixture
Spunlace non-woven cloth replace gauze.Because its technique is simple, automaticity is high, and the cost of spunlace non-woven cloth is than woven cloths more
It is low, then it is widely used in the disposable products of multiple use.However, Johnson ＆ Johnson's type non-woven fabrics, which can only be used to manufacture, requires ratio
Relatively low common medical absorbent dressing.The above-mentioned open surgery and the dressing compared with small incision surgery of being used for can not use Johnson ＆ Johnson's type spun lacing
Non-woven fabrics be made because its tensile strength is low, and the requirement for water suction dressing of performing the operation is then very strict.Recently, also someone tastes
Cotton spunlace non-woven cloth manufacture dressing on probation.However, it is very limited using the situation of cotton non-woven dressings in operation, because nothing
It is quite stiff to spin the casting product of cotton, and its cost is too high thus can not attract the attention of hospital.

The present invention is following research and discovery based on inventor and completed：
(a) spunlace non-woven cloth：Although the unsuccessful example of trial of past useful spunlace non-woven cloth manufacture dressing, inventor
Still cloth of the decision by the use of spunlace non-woven cloth as the dressing for making the application.Spunlace non-woven cloth is wound fine by using water jet
Layer is tieed up to form varying strength, thickness and the non-woven fabrics of grammes per square metre.Different from the manufacture of gauze, the manufacture of spunlace non-woven cloth is more automatic
Change, more energy efficient, labour is lower, and cost benefit is higher.In addition, gauze changes into different water imbibition dressing and spunlace non-woven cloth
Conversion contrasted, gauze needs more procedure of processings and hand labour.
(b) string is as raw material：In all fibers for being usually used in production non-woven fabrics, string is inhaled because of its height
Water-based and flexibility and it is well-known.Except string, we are further contemplated using bamboo fibre, but its cost is slightly higher, fibre whiteness compared with
It is low；This 2 points all make string than bamboo fibre more attractive.
(c) spunlace non-woven cloth of high elongation intensity and cross lapping：Its prerequisite of the dressing used in operation be
High elongation intensity on warp-wise and broadwise.It should be noted that the low tensile strength in either direction will feel dressing
Weak and easily tear, this is worthless feature for operation application.As described above, because tensile strength is low particularly in dressing
Latitude be pulled up low intensity, Johnson ＆ Johnson's type is only used for general applications without anti-pieces of cloth and cannot be used for performing the operation.In spun lacing nonwoven
In cloth technique, how the tensile property of finished product spunlace non-woven cloth depends on selected raw fibre, processing conditions and fiber
It is layered on the net mould of production line.If each fibrous layer of spunlace non-woven cloth is consistent in net mould upper berth set direction, the cloth manufactured
Referred to as parallel lapping.If direction of each fibrous layer of spunlace non-woven cloth on net mould is in 90 degree, such spun lacing nonwoven
Cloth is referred to as cross lapping.Identical material and both spunlace non-woven cloths of weight are contrasted, the spunlace non-woven cloth of parallel lapping
Feel is more soft, because the tensile strength of its broadwise is than through upward much weaker.On the contrary, the spunlace non-woven cloth feel of cross lapping
It is harder, because the tensile strength of warp-wise and broadwise can be strong on an equal basis.Johnson ＆ Johnson's type spunlace non-woven cloth piece, is by the nonwoven of parallel lapping
Cloth is made, and its tensile strength is relatively low especially in broadwise.Spunlace non-woven cloth in the high-hydroscopicity operation dressing of the application uses
The spunlace non-woven cloth of cross lapping, its tensile strength on warp-wise and broadwise are all higher.Using cross lapping technique, spun lacing without
The tensile strength spun in cloth warp-wise and broadwise can be pressed onto the pressure value on non-woven fabrics by production line to be controlled.For
The high-hydroscopicity operation dressing of the application, minimum tensile strength of the spunlace non-woven cloth on warp-wise and broadwise are all not lower than 18 Ns
, the test sample used during test is the operation towel piece (monolithic) of 5 centimetres of (width) × 10 centimetre (length), tensile strength tester
Crosshead speed be about 20 cm per minutes.
(d) high water absorbing ability dressing：Another advantage using string spunlace non-woven cloth is its high water absorbing ability.
For the high-hydroscopicity operation dressing of the application, in production and processing, spunlace non-woven cloth production line and string can be selected
The parameter value of grade, and then ensure that the water absorption of each operation towel piece reaches more than 6 times of its own weight.By contrast, yarn
The water absorption of dressing made of cloth is typically about 2~4 times of its weight, and being primarily due to gauze has the mesh of perforate.Need to note
Meaning, the test of the water absorption of dressing, is to pre-process test sample 24 hours in controlled indoor environment, uses calibration
Title measure the weight of initial (drying) test sample, test sample is inserted in water 30 seconds, it is taken out from water, held
It 30 seconds, then measure the weight of (wet) test sample with the title of calibration again.Every water absorption is exactly every built-in testing sample
The difference of final weight (weight in wet base) and initial weight (dry weight), it is expressed as " per the grams of built-in testing sample water suction ".In addition, unit
Water absorption, with the final weight and the difference of initial weight divided by the initial weight of test sample of every built-in testing sample, it is expressed as
" grams of every gram of test sample water suction ".
(e) dressing of the soft surface without light：One of spunlace non-woven cloth also has its table common problem encountered is that its outward appearance is stiff
The light in face often makes fabric look like a piece of paper.This problem is even more serious on the high fabric of tensile strength.However, more
Preferably surface (or even fabric with high tensile force) of the non-woven fabrics of dressing with softness, because this feel will increase
User is to the water imbibition for operation and the confidence of pliable characteristic.Because fiber must be compacted at high temperature, therefore spun lacing
The surface of non-woven fabrics has been coupled with stiff sense and light, and spunlace non-woven cloth also just has high tensile.On a molecular scale, it is high
Press together with causing the strand of fiber to be closely aligned with the pressure that high temperature lower fibrage is subject to, so as to produce spun lacing nonwoven
The high tensile of cloth and the light on surface, then the surface of spunlace non-woven cloth appeared to have light.In order to soften nonwoven
The surface of cloth simultaneously removes its light, can use sofening treatment method, using first being carried out using water to spunlace non-woven cloth at humidification
Reason, then drying and processing is carried out to the spunlace non-woven cloth after humidification under predetermined drying temperature, wherein, in humidification process
In, the mass ratio of the spunlace non-woven cloth before the water and humidification in the spunlace non-woven cloth after humidification is 0.05~1:1,
In drying and processing, drying temperature is 25 DEG C~90 DEG C.After sofening treatment, the Surface feel of spunlace non-woven cloth is soft and does not have
Light.In addition, its high elongation intensity is not affected.
(f) there is the dressing of other premium properties：The trimming of spunlace non-woven cloth will not produce fine hair or yarn and thread head, therefore not
It is required that washed in advance.In addition, spunlace non-woven cloth will not be pasted onto on exposed wound.On the contrary, only selvedge, cotton weaving yarn cloth
Have trimming.Therefore, fine hair and yarn and thread head are often being seen made of gauze in dressing, this may cause to infect and delay wound
Healing.For large-sized dressing such as laparotomy sponge, then pre- washing is required to remove fine hair and yarn and thread head.Should be considerable
It is that the washing of gauze and subsequent drying are labour-intensive and high energy consumption processes.
(g) dressing sheet with X-ray radiopaque tracking line or piece.One drawbacks common of spunlace non-woven cloth is its exposure
Tolerance in high temperature environments is low.When being higher than 120 degrees Celsius of environment exposed to temperature, spunlace non-woven cloth will become from white
Yellow and brown, and the temperature for making cotton gauze color change is about 140 degrees Celsius.To the low tolerance of high temperature to cotton yarn abdomen
It is not a problem up that X-ray tracking piece, which is adhered to product, for portion's operation towel, because cotton yarn laparotomy sponge size is big, four
Side is always stitched together, so X-ray tracking piece also is sewn into cotton yarn belly dressing sheet up.On the contrary, the low tolerance to high temperature
Property for string spunlace non-woven cloth, it is meant that X-ray tracking line is heat fused on non-woven fabrics manufacture band X-ray and follows the trail of line dressing
Piece turns into a significant challenge, because the fusing point of X-ray tracking line is about at 130 degrees Celsius.This problem can be by first doing one
Individual instrument transfers heat to X-ray tracking line itself, then X-ray tracking line is heat fused on string spunlace non-woven cloth to solve
's.Therefore, the temperature of string spunlace non-woven cloth is far below its non-discolouring limiting temperature, and spunlace non-woven cloth is exposed to
The time of hot environment is very short.
(h) dressing of security is improved：As it was previously stated, a use of subject matter of dressing is unexpectedly to stay dressing
In patient body.Many times dressing can be saturated with blood in use, and this makes it be difficult to find that after surgery.With gauze abdomen
When portion's operation towel is compared, operation dressing made of the string spunlace non-woven cloth of the application is more visible than gauze dressing in operation
Spend it is much better because：
(1) the water demand ratio gauze dressing of operation dressing made of plant fiber non-woven fabric is higher by about twice.Therefore, blood
Operation dressing made of the plant fiber non-woven fabric being saturated with is at least twice of equal gauze dressing size, therefore is easier to be sent out
It is existing.
(2) laparotomy sponge of gauze has many gauffers, so is easy to be rolled up after blood is saturated with.Crimp, open
The mesh in hole and the gauze laparotomy sponge for being saturated with blood of smaller volume make its laparotomy sponge with plant fiber non-woven fabric
Compared to being easier to be missed, and the belly dressing sheet operation towel of plant fiber non-woven fabric is more flat, without the mesh of perforate, is saturated with
Meeting swelling volume becomes big after blood.
The high-hydroscopicity operation dressing of the application is more much higher than the water absorbing capacity of existing gauze dressing, and this will make operation
The middle dressing sheet number used becomes less.A for example, example：Gauze laparotomy sponge is typically every 5 and ties up and pack, side
Just points every time perioperatively.When using the operation dressing of the application, as laparotomy sponge, its water absorption is gauze belly
Twice of operation towel, it is only necessary to which 3 or lesser amount of laparotomy sponge just can absorb same amount of blood.Another example：
Gauze X-ray follows the trail of line dressing sheet, and it is typically every 10 and ties up and pack, is perioperatively counted each with facilitating.Work as use
The new operation dressing of high water absorption of the application is as dressing sheet, and it is typically every 10 and ties up and pack, to facilitate in each operation
Front and rear points.Its water absorption is gauze X-ray tracking twice of line dressing sheet, it is only necessary to which 5 or smaller amounts absorb equal amount
Blood.Count easier more because 3 are carried out with points and compares 5, and more difficult make mistakes.5 are carried out
Points compare 10 and count easier more, and more difficult make mistakes.Therefore, when use the application is by string
When dressing sheet made of nonwoven is compared with using existing gauze X-ray tracking line dressing sheet, the dressing sheet of the application point after surgery
Wrong number and the possibility being retained in patient body will significantly reduce than gauze X-ray tracking line dressing sheet, and this will be better than existing
Gauze X-ray follows the trail of line dressing sheet.
It is it is additionally noted that current in the unexpected possibility for leaving dressing, many hospitals in patient body in order to reduce
Computerized system and bar code system is used to count dressing perioperatively.There are some hospitals to make in addition
With radio frequency (RF) chip being sewn in dressing, and the detection device supporting with it is used in combination, so that ensure will not
Dressing is being left in patient body.Using the application high-hydroscopicity operation dressing, it is necessary to bar code or RF chips etc number
Amount will be reduced, because being reduced to the quantity required of dressing, the work of counting can also be reduced therewith.Therefore, for being used
The hospital of these systems, the cost on these computerized and detection system materials and operation will be greatly lowered.
High-hydroscopicity operation dressing in the application uses characteristic and excellent water imbibition with many protrusions, and this makes to apply
Material is more readily spotted after surgery, reduces the dressing quantity needed for identical operation, and significantly improve the overall security of operation.
In addition, its material cost and the cost of the existing gauze product of manufacturing cost ratio are much lower, this can be that hospital saves great number cost.
It should be noted that inventor has found, if it is desired, highest weight accounting can also be added in string is
40% cotton fiber, without there is too big change to required performance, and spun lacing life will be significantly reduced more than 40% cotton fiber
The efficiency of producing line, and the pliability of spunlace non-woven cloth.
