Embodiment

Band is related to, is a kind of belt for being used to tie up thing applied widely, itself is provided with joint, typically not Instrument auxiliary is needed to complete to tie up.Stopping function is designed with simultaneously, the more can only prick the more tight.Certainly, it is detachable there is also having The band of function.

Band is divided into metal binding belt and Plastic Bandage, in the present invention preferred Plastic Bandage, wherein, Plastic Bandage is generally Nylon cable tie, small-sized nylon cable tie cost during batch production is cheap, and the price of the small-sized nylon cable tie of wall scroll is generally below 1 point Money, the cost of the preferably small-sized nylon cable tie of quality can also be less than 2 points of.

Nylon cable tie possesses very high intensity, it is seen that, can be with using the relatively large band of width in some news Substitute handcuffss.

Preferably, in the present invention, band is made of the nylon66 fiber material of UL accreditations, fire-protection rating 94V-2, acidproof, rotten Erosion, insulating properties is good, non-aging, in light weight, safe and non-toxic, endurance is strong.Operation temperature is subzero 40 to 90 degree.Integrated machine Tool performance is far superior to common engineering plastics, is that instead of the ideal material of copper, stainless steel and other non-ferrous metals.

Band product has the characteristics that quick colligation, good insulating, self-locking fasten, are easy to use.Therefore, although in this hair Three lock solid structures are employed in bright, but operate also can be quickly.

The general structure of such as infusion vessel, mainly bottleneck structure are seen again, and bottleneck structure is all revolving body at present, together When, the bottleneck of revolving body is all variable-diameter structure, and the cap of general bottleneck is larger, thus possesses preferable colligation basis.

For the puncture outfit on disposable syringe, primarily now there are two types, a kind of is the puncture outfit of plastic material, Another kind is the puncture outfit of metal structure, but no matter which kind of puncture outfit, its shank can all have a collar or similar structures, because And the restraining structure of ring set can also be formed using collar.

Further, since puncture outfit and bottleneck diameter are relatively all smaller, therefore, can meet to require using small-sized band, Holistic cost compares relatively low, can be used as consumptive material.

According to preferred embodiment, referring to Figure of description 1 to 5, a kind of disposable syringe annex, for disposably noting Fixation of the emitter on infusion vessel, its basic structure include the first band for being engaged on infusion vessel bottleneck and are used for The second band being engaged on disposable syringe puncture outfit, such as it is located at the band described in the 3rd band 5 of bottom in Fig. 1, with And the first band that remainder is formed.

As shown in figure 1, enough into Up-Center-Down Structure, top can be used for tying up for bottleneck, and bottom can be used for puncture outfit Tie up, middle part is then used for the connection of upper and lower two parts.

Therefore, the band of a usual only band is different from, in the present embodiment, is pricked using first with two bands Band, sees the structure shown in Fig. 1, and in figure, the first band includes the first joint 2, and starts from the first joint 2 and orthogonal The band 3 of first band 1 and second, wherein first band 1 form superstructure, and the second band 3 forms central structure.

General small-sized band is directly integrally formed, and is even configured with two bands, and its holistic cost is also than relatively low, by surveying Calculate, during batch production, meet that the cost for the first band that the present invention uses below two points of, can use as consumptive material.

Wherein, first band 1 can directly match connection with the first joint and form the first ring, be tightened for ring set for example above-mentioned Bottleneck.

It is understood that band itself, which possesses, ties up a range of object, commonly referred to as it is stranded and pricks scope, in Fig. 6 Shown E meanings are to tie up scope, such as some small-sized bands, and belt length (including joint when belt length is calculated in specification) is During 60mm, the general minimum of its value of tying up can reach 2mm, and maximum can reach 11mm.

When bottleneck is relatively large, longer band can be selected.

Further, formed with the third channel for including the 3rd lock part and being adapted to first band 1 on the first joint 2.

Second band includes the second joint 4 and starts from the 3rd band 5 of second joint 4；On second joint 4 formed with It is mutually perpendicular to and is respectively equipped with the first passage 48 and second channel 49 of lock part；

Wherein, first passage 48 adapts to the second band 3, and second channel 49 adapts to the 3rd band 5.

In use, can be by 1 advance colligation of first band on bottleneck, the 5 advance colligation of the 3rd band is on puncture outfit, caregiver Member is connecting the second band 3 and the second joint 4 after the completion of being punctured to patient.

Due to the higher additional connection of a relative intensity be present, when such as patient is with toilet is gone to, walks and produced Raw rocks the abjection that will not cause puncture outfit, and for infant patient, it has no ability to break on the second band 3.

Simultaneously as band is backstop structure, infant also has no ability to extract out band.

Comparatively, the operation on band, it is generally only to tense the band of correlation through related passage, than making The speed being bonded with adhesive plaster is also fast, thus, efficiency is very high.

Meanwhile nylon cable tie is that comparison is hygienic, and cost, than relatively low, the negative of patient will not also be increased by being used as consumptive material Load.

Do not possess the band of such as knot that can be undone by a pull in general, can by the way of the second band is directly blocked, that is, Under lashed state, the part blocked between the first joint 2 and the second joint 4, the part being connected with the second joint 4 can be direct Pulled out from lower end, operation is convenient to.

And then it is banded in the connection infusion vessel of the part on bottleneck and is abandoned together as medical waste.And it is banded in puncture Part on device can be also used for next infusion vessel.Generally speaking, in an infusion treatment, one second is at most used Band and a plurality of first band.

Therefore, even also can be very low using the annex as consumptive material, its use cost, during batch production, two bands Cost can control at 2 points~4 points, a plurality of first band, its overall cost control are used in an even infusion treatment System also can be than relatively low.

Band possesses relatively good self-locking structure, and infant has no ability to make its lock-off, even knows that cutting can solve Except constraint, generally also without condition.

In some applications, the second band 3 and matching somebody with somebody for first passage 48 are combined into the cooperation of knot that can be undone by a pull head or coordinated for fork.

Band species is various, and conventional band just has as many as tens of kinds, and nylon cable tie is used in the present invention, is pricked for nylon Band, there is also knot that can be undone by a pull band and latch band, the use of both bands can avoid the destruction to the first band, if necessary may be used To be reclaimed to band, certainly, because band is cheap, having little significance for sterilization is gone in recovery again.But it can release manually Locking is meaningful for the operation of nursing staff.

Either knot that can be undone by a pull band or latch band all possesses certain operation skill, and therefore, infant does not possess generally The ability of operation, for infant, it is generally only drawing infusion tube, rocks infusion tube back and forth, this is not enough to cause for example The disengagement of knot that can be undone by a pull band.

In certain altitude, infant does not reach this annex typically yet, is even easier for usual infusion vessel hanging Lock-off, its use is not interfered with generally also.

In certain embodiments, to avoid slightly larger child from directly contacting this annex, so as to being removed, first when adopting When being coordinated with fork, using night bolt, spring therein is using the spring with predetermined stiffness factor, it is necessary to certain power Gas could subdue night bolt, similar to the safety head used in current medicine bottle, it is necessary to which larger strength is by bottle cap pressure Under can rotating opening.Therefore, effectively children can be avoided to open this annex in this way.

In certain embodiments, there is provided a kind of new knot that can be undone by a pull head, the knot that can be undone by a pull head are directly constructed on first passage 48, are utilized The wall of first passage 48 is as matrix, thus the knot that can be undone by a pull head engagement formation is：

Form wall relative with its lock part on the conduit wall of first passage 48 and be provided with the hole relative with its lock part, so Lock part is depressed by hole can, so as to contact locking, the second band 3 of pulling back, you can pull out the second band.

To avoid interference with, the second band 3 needs to have specific structure, thus, as shown in figure 5, correspondingly, the second band 3 wraps Flank of tooth section and the target seeker positioned at extending end are included, and the bar hole extended along the bearing of trend of the second band 3 is provided with the second band 3 31；

The bar hole 31 covers whole flank of tooth section and part target seeker in their extension direction.

When pulling out the second band, it is used to press the object can of lock part to cross flank of tooth section by hole, so as to be moved to Target seeker, the object is exited, continue to pull out target seeker.

Using this structure, infant does not possess the ability and object of pull-out, effectively it can be avoided to break annex It is bad.

Lock part as shown in Figure 3, i.e. the first lock part 44 and the second lock part 47, the sheet being usually obliquely installed Body, in preferred embodiment, plates one end relative with flank of tooth section is provided with multiple teeth, can form more preferable locking.

Back during drawstring, the angle of inclination of inclined plates can change, or angle of inclination tends to right angle, in tooth Length on the vertical direction of face section, form locking.When plates are depressed, that is, prevent its side in this direction It is long, so as to which flank of tooth section is pulled out.

In small-sized band, plates generally only have one, therefore, it are operated also relatively simple.

If using two plates, the hole can then use the structure of bar hole, can an action depress simultaneously Two plates.

In some preferred embodiments, two longitudinal edges in the bar hole 31 (the namely bearing of trend of band, then on zone face The direction perpendicular with it is laterally) between be equipped with the husband of sister 32, thickness compares relatively thin, and it is relatively simple to destroy the husband of sister 32. However, the relatively weak structure of intensity possesses the effect for preferably improving intensity in some cases.It is in the present embodiment Typical case.

The husband of sister 32 can be simple film layer, covering whole piece bar hole 31 or monolithic array structure, pull out second During band, it can utilize and press the part of lock part to scratch the husband of sister 32.

Preferably, the thickness of the husband of sister 32 is 0.1~0.25mm, is approximately equivalent to thicknesses of layers, spacing is 8~ 10mm, width (namely adaptable transverse width) is 1~2mm.

, can be only between the second band 3 of matching and the second joint 4 on such as knot that can be undone by a pull band structure in view of foregoing content Connection, it is not necessary that the connection between such as the 3rd band 5 and the second joint 4 also uses knot that can be undone by a pull band structure, its own cost It is very low, used as typical disposable device.

Further, the hole is the gap hole extended along the direction of first passage 48, based on this, can be inserted using plates Enter gap hole, form reliable pressure holding.

To avoid the excessive intensity for slackening the second joint, the length in the gap hole accounts for the two of the length of first passage 48 2/1 mono- to three.

In certain embodiments, the band 5 of first band 1 and the 3rd is followed successively by smooth surface section, flank of tooth section and led in their extension direction Leader, the wherein length of smooth surface section tie up the corresponding band portion equal length of value to first band, second with corresponding minimum.

See that Fig. 6, E represent to tie up value, band there are the minimum technical requirements for tying up value, lost when on the one hand tying up value less than minimum The ability of tying up is gone, can besides cause the curvature for tying up the circle to be formed excessive, cause to tie up failure.

The design of smooth surface section can intuitively observe that minimum ties up value, so as to more preferably carry out the selection of band.

Further, referring to Figure of description 4, the one side of the flank of tooth 52 is the flank of tooth, and the one side relative with the flank of tooth is Smooth surface；

Wherein, the flank of tooth includes：

Formed the flank of tooth rectangular recess on the whole；

Tooth using groove-bottom as basal plane, groove is higher by the top of the tooth, the structure can reduce materials, and overall structure phase To compact.

Band is not machining, and recessed part can reduce the integral thickness of band, thus materials are relatively fewer.

In addition, trough rim may be used as being oriented to, it can be separated with teeth portion, so as to be found in the via structure shown in Fig. 3.

In the structure shown in Fig. 3, the cross section of the first passage 48, second channel 49 and third channel is T Type, so as to be configured to the relatively small upper via of width relatively large lower via and width, such as the first mistake shown in Fig. 3 Upper via corresponding to hole 42, the 4th via 46, the lower via corresponding to the second via 43 and the 3rd via 45, is integrally formed T Type hole, the band section structure shown in Fig. 4 can be matched, form reliable guiding and constraint.
