Description

Tourniquet

Technical field

The utility model belongs to the field of medical instrument technology, more specifically, be related to one kind can quick and convenient adjusting pine Tight and unlock tourniquet.

Background technique

As the essential hemostasis equipment of field first aid, tourniquet mainly have rubber tourniquet, fastening-type hemostasis band and Three kinds of rotary extrusion type spinning tourniquet.Rubber tourniquet is difficult to control pressure and local damage is heavier, and fastening-type hemostasis band effect is (especially To lower limb bleeding) risk not good enough and in the presence of unexpected loose band, there is also operate not convenient enough, inconvenient fine tuning pressure for rotary extrusion type spinning tourniquet The deficiencies of power.Therefore the prior art tourniquet operate convenience, functionality, in terms of need to be improved.

Utility model content

The technical problem to be solved by the utility model is to being directed to the deficiencies in the prior art, a kind of structure is provided Simply, easily controllable, being capable of the tourniquet of adjusting elasticity and quick release at any time.

Solve the problems, such as techniques discussed above, the technical solution that the utility model is taken are as follows:

The tourniquet of the utility model, band body, buckle switch and setting including strip adjust the band bodily form on band body At annular caliber size inching switch；The buckle switch includes pin thread and female thread, and one with body is arranged in the pin thread End；The one side with body is provided with rack gear along tape body length direction；The inching switch is fixedly connected with female thread, between the two It is provided with the through slot passed through with body；The rack gear on body by with the cooperation of the inching switch of through slot side realize it is fixed with it is micro- It adjusts, the female thread matches the switch for realizing tourniquet with pin thread.

Further, it is provided on the inching switch and the tooth intermeshing on rack gear and openable and closable lock pawl.Pass through Tooth intermeshing on lock pawl and rack gear, the annular caliber size that adjustable band body is formed reach just to adjust pressure The degree of hemostasis.

Further, there are two the lock pawls on the inching switch, the rack gear is engaged with two lock pawls.Two stop Pawl must separate simultaneously with rack gear and just be able to achieve fine tuning, by the way that two lock pawls are arranged, can form dual fail-safe, reduce unexpected pine The risk of band.

Further, the buckle switch is singly-key type buckle switch or kinds of point mode buckle switch.

Preferably, buckle switch is kinds of point mode buckle switch, by setting kinds of point mode buckle switch, can form dual fail-safe, Reduce the risk of unexpected loose band.

Further, cotton pad layer is provided on another side opposite with rack gear on body.By the way that cotton pad layer is arranged, can reduce Damage of the tourniquet to limbs.

The tourniquet of the utility model when in use, first enclosing around limbs one the band body of tourniquet, then by pin thread and female Button fastens, and the function of hemostasis can be realized in the free end of last puller strap body.If you need to slightly loose tourniquet, can hold on the other hand with body Free end, the other hand separate lock pawl with rack gear by inching switch, can be adjusted.If you need to thoroughly unclamp tourniquet, Then directly pin thread and female thread are unlocked.

The utility model tourniquet is not only easy to carry, operation is convenient, small to local damage, and structure is simple, is easy to control System, being capable of adjusting elasticity and quick release at any time.

Specific embodiment

An infinite embodiment is provided with reference to the accompanying drawing to be further elaborated the utility model.But it should Understand, these descriptions are only exemplary, and are not intended to limit the scope of the utility model.In addition, in the following description, being omitted To descriptions of well-known structures and technologies, to avoid the concept for unnecessarily obscuring the utility model.

Embodiment one

As shown in attached drawing 1,2,3,4,5,6, tourniquet, band body 1, buckle switch 2 and setting including strip are in eye-splice Inching switch 3 of 2 lower section of switch to adjust the annular caliber size formed with body 1.Buckle switch 2 includes pin thread 21 and female thread 22, one end with body 1 is arranged in pin thread 21, and the one side with body 1 is provided with rack gear 11 along its length, and another side is provided with cotton Bed course 5.Inching switch 3 is fixedly connected with female thread 22, is provided with the through slot 4 passed through with body 1 between the two.With the rack gear on body 1 11 by realizing that fixed and fine tuning, female thread 22 match realization tourniquet with pin thread 21 with the cooperation of the inching switch 3 of 4 side of through slot Switch.It is provided on inching switch 3 with the intermeshing of tooth 111 on rack gear and openable and closable lock pawl 31, lock pawl 31 has Two, rack gear 11 is engaged with two lock pawls 31.

As shown in Figure 5,6, when operation, first the band body 1 of tourniquet is enclosed around limbs one, then pin thread 21 is injected into female thread 22 In, operation can be completed in the free end of last puller strap body 1.Lock pawl 31 on inching switch 3 and 111 phase of tooth on rack gear 11 Mutually tourniquet can be effectively prevent reversely to loosen after engagement, if you need to slightly loose tourniquet, the free end with body 1 can be held on the other hand, it is another Hand makes lock pawl 31 be detached from 111 slot of tooth on rack gear 11 by inching switch 3, can be adjusted.If you need to thoroughly unclamp hemostasis Band then directly unlocks pin thread 21 and female thread 22.

Embodiment two

The present embodiment and embodiment one the difference is that: lock pawl 31 is one, and buckle switch 2 is that singly-key type eye-splice is opened Close 2.

Embodiment three

The present embodiment and embodiment one the difference is that: lock pawl 31 is two, and buckle switch 2 is that kinds of point mode eye-splice is opened Close 2.

The hemostasis band structure of the utility model is simple, it is easily controllable, being capable of adjusting elasticity and quick release at any time.

The above embodiment is interpreted as being merely to illustrate the utility model rather than limits the guarantor of the utility model Protect range.Read the utility model record content after, technical staff the utility model can be made it is various change or Modification, these equivalence changes and modification equally fall into the utility model claims limited range.
