Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, the utility model provides a screw mouth to straight mouth conversion equipment of screw mouth syringe, including adapter overall structure 1, the inside of adapter overall structure 1 is provided with the adapter cavity 2 that extends to the both ends of the central line of length direction and communicates with the outside, the junction of adapter cavity 2 and one end of adapter overall structure 1 is provided with syringe screw mouth link 3, the week side of the tip that is provided with syringe screw mouth link 3 on adapter overall structure 1 is provided with a plurality of syringe screw mouth draw-in grooves 4 around the central point;
wherein, the end shape of the adapter integral structure 1 deviating from the screw mouth connecting end 3 of the injector is the same as the nipple of the straight-mouth injector, and the screw mouth connecting end 3 of the injector is engaged with the screw mouth thread of the screw mouth injector.
When the utility model is used, the end shape of the adapter integral structure 1 deviating from the screw port connecting end 3 of the injector is the same as the nipple of the straight-mouth injector, so as to be used in cooperation with other instruments connected with the straight-mouth injector.
The adapter overall structure 1 is in meshed connection with a screw thread on a screw injector through an injector screw connection end 3, so that a hollow cavity 2 in the adapter overall structure 1 is communicated with the inside of the screw injector, medicine injected by the screw injector enters the hollow cavity 2 in the adapter through the injector screw connection end 3, and is discharged from the other end of the adapter hollow cavity 2 communicated with the adapter overall structure 1 into other corresponding instruments, such as a pipeline for nasal feeding and the like.
Through the connection of the screw-mouth connection end 3 of the injector and the screw-mouth thread on the screw-mouth injector, the nipple of the screw-mouth injector is converted into a nipple similar to a straight-mouth injector, and the problem that the cost is increased due to the fact that the screw-mouth injector and the straight-mouth injector of the same specification need to be stored in clinical departments is avoided.
The syringe screw mouth clamping groove 4 is used for being held by an operator to rotate the adapter integral structure 1 to be meshed with the screw mouth syringe screw thread, so that the operator can conveniently operate the adapter.
The overall structure 1 of the adapter is in a circular truncated cone shape, the diameter of the radial section of the overall structure 1 of the adapter is linearly reduced along the axial direction, and the diameter of the radial section of the end part of the overall structure 1 of the adapter, which is provided with the syringe screw port connecting end 3, is the largest.
Because crossover sub overall structure 1 establishes in the nipple outside of screw injector through the spiral port screw thread interlock adapter sleeve on syringe spiral port link 3 and the spiral port syringe, make 1 cover of crossover sub overall structure establish the volume that the nipple is outside to be greater than normal syringe, and radial cross-section reduces gradually along the diameter of the round platform form crossover sub overall structure 1 of axial diameter, thereby make the tip of keeping away from syringe spiral port link 3 on the crossover sub overall structure 1 the same with the nipple size of the straight mouthful syringe of specification, so that use with the apparatus connection that corresponds.
The diameter of the radial section of the hollow cavity 2 in the adapter is linearly reduced along the axial direction, and the diameter of the radial section of the position, close to the screw port connecting end 3 of the injector, in the hollow cavity 2 in the adapter is the largest.
The diameter of the radial section of the cavity 2 in the adapter is linearly reduced along the axial direction, so that the situation that the pushing pressure of the medicine pushed and injected by the screw mouth injector suddenly decreases when the medicine enters the cavity 2 in the adapter due to the fact that the size of the nipple of the screw mouth injector is smaller than the size of the cavity 2 in the adapter is avoided, and the influence on the pushing and injecting of the screw mouth injector is reduced.
The adapter overall structure 1 is sleeved with an adapter protective sleeve 5, and the adapter protective sleeve 5 is sleeved on the adapter overall structure 1 from the end part of the adapter overall structure 1 deviating from the syringe spiral clamping groove 4.
The adapter protective sleeve 5 is slidably sleeved on the adapter overall structure 1 and is fixed through friction between the adapter protective sleeve 5 and the adapter overall structure 1, so that the outer wall of the adapter overall structure 1 can keep the aseptic principle of the syringe in the using process.
Be provided with annular plate 6 around the axis on crossover sub overall structure 1, the last 4 one sides that deviate from syringe spiral draw-in groove of annular plate 6 are provided with annular seal 7 with one heart, and crossover sub protective sheath 5 tip and annular seal 7 counterbalance when the cover is established to crossover sub overall structure 1.
Through setting up annular plate 6 on crossover sub overall structure 1 in order to set up ring type seal 7 for crossover sub protective sheath 5 cover is established on crossover sub overall structure 1 later the tip and is supported with ring type seal 7, has further improved the leakproofness to the surface of crossover sub overall structure 1, and then has improved the protection effect of crossover sub protective sheath 5.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
