Abstract
The utility model provides a medical retention needle with an elastic positive pressure tube sealing clamp. According to the medical retention needle, the elastic positive pressure tube sealing clamp is sleeved on an infusion tube which is connected with a needle head and an infusion plug; an upper clamping plate and a lower clamping plate which are used for clamping and sealing the infusion tube are arranged in the tube sealing clamp; two end sockets at an elastic opening on the upper side are provided with a stop weir and a clamping head; and an integrated clamp opening press head is connected to the outer side of the stop weir. When the tube is sealed by using the retention needle during the infusion of patients, medical care personnel only perform pulse type injection conventionally by using 5 milliliters of physiological saline; when 1 milliliter of physiological saline is left, the physiological saline is injected continuously by one hand, and the elastic positive pressure tube sealing clamp is clamped quickly by the other hand, namely the infusion tube can be sealed; and due to the adoption of an elastic extrusion mode of the tube sealing clamp, the physiological saline in the infusion tube also can be injected to blood vessels quickly again in the extrusion process, so that the retention needle is in the positive pressure state, and the phenomenon of tube stoppage caused by blood return can be avoided effectively; and the medical retention needle is operated stably and conveniently.
Description
Technical field
This utility model relates to a kind of medical retention pin, a kind of specifically medical retention pin with elasticity malleation tube sealing folder.
Background technology
In the clinical nursing activity,, can reduce the misery that the patient brings because of repeated localised puncture now because remaining needle is not easy dropped stitch; And can correspondingly alleviate nursing staff's working strength, be widely used by patient's acceptance and nursing staff, in the operation and maintenance process of remaining needle; Must carry out the remaining needle tube sealing after each transfusion, and the tube sealing that existing remaining needle is worn folder is the bar shaped clip slot of a sheet type, during use; After injecting normal saline with syringe, through with the thin tube for transfusion of remaining needle from clip slot to narrow groove pull take out tight could the tube sealing effect, when practical application; The nursing staff is with injecting on the other hand normal saline, pulls with another and pulls the mode of taking out tight shutoff and seal folder and can't normally accomplish at all, in tube for transfusion appears in regular meeting, produces negative pressure and causes blood back phenomenon in the tube for transfusion; After blood back solidifies in the remaining needle tube for transfusion; Just can't continue to use remaining needle, the misery that both can cause the patient to puncture again also can increase patient's corresponding expense.
Summary of the invention
This utility model provides a kind of medical retention pin with elasticity malleation tube sealing folder, can avoid remaining needle blood back plugging situation, and scientific structure be simple effectively with the tube for transfusion shutoff of remaining needle, and is extremely easy to use.
This utility model, the technical scheme that is adopted is: said remaining needle is set with an elasticity malleation tube sealing folder on syringe needle and transfusion tube for transfusion that plug linked to each other, in tube sealing presss from both sides, be provided with can be with tube for transfusion clamping shutoff on lower plate.Elasticity malleation tube sealing folder produces return elasticity through the curved arc location of front and back side, and promptly the curved arc location changes back, location restorable.
In the technique scheme: the elasticity malleation tube sealing folder of institute's suit is the ellipse clamp of a band elastic opening; Be provided with a tube for transfusion perforation in the centre of elasticity malleation tube sealing folder; Vertically between two perforation, two terminations at elasticity malleation tube sealing folder upside elastic opening place are respectively arranged with the dop of retaining bank and correspondence to the interior last lower plate that is provided with.
What the outside that said elasticity malleation tube sealing is clipped in the retaining bank connected promising one opens the folder head.
This utility model is through technique scheme, owing to the tube sealing folder with remaining needle has adopted above-mentioned technical pattern, during use; Only need of the up and down extruding of a quick-moving speed with the tube sealing folder; Dop just can snap in the retaining bank, and last lower plate promptly constitutes the stable state that closes up, the while can be when the tube sealing clamping is held together with tube for transfusion in normal saline push into fast to make in the blood vessel and form barotropic state in the tube for transfusion; Realize effectively with the tube for transfusion shutoff; This utility model has effectively solved the very inconvenience and the problem that causes the shutoff blood back easily in the use of existing remaining needle sheet type bar-shaped trough, and it is simple to have a scientific structure, reliable distinguishing feature extremely easy to use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment this utility model is done further to detail.
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model elasticity malleation tube sealing folder perspective view.
Fig. 3 is the stifled view of this utility model elasticity malleation tube sealing clamp.
Among the figure: 1, syringe needle, 2, the transfusion plug, 3, tube for transfusion, 4, elasticity malleation tube sealing folder, 5, perforation, 6, go up lower plate, 7, the retaining bank, 8, dop, 9, open the folder head.
The specific embodiment
Shown in accompanying drawing 1 embodiment: remaining needle is set with an elasticity malleation tube sealing and presss from both sides 4 on syringe needle 1 and the tube for transfusion 3 that linked to each other of transfusion plug 2; In tube sealing folder 4, be provided with can be with tube for transfusion 3 clamping shutoff on lower plate 6; The elasticity malleation tube sealing folder 4 of institute's suit is the ellipse clamp of a band elastic opening
Centre at elasticity malleation tube sealing folder 4 is provided with a tube for transfusion 3, and vertically between two perforation 5, two terminations that elasticity malleation tube sealing presss from both sides 4 upside elastic opening places are respectively arranged with retaining bank 7 and corresponding dop 8 to the last lower plate 6 that is provided with in the perforation 5.Elasticity malleation tube sealing folder 4 connects opening of promising one in the outside of retaining bank 7 and presss from both sides head 9.
Shown in Figure 2: elasticity malleation tube sealing folder 4 is spatial side-looking state; The both sides, front and back respectively are provided with the perforation 5 of a tube for transfusion 3; In the middle of last lower plate 6 was positioned at, the two ends of top opening part were respectively retaining bank 7 and dop 8, connected opening of promising one at retaining bank 7 upsides and pressed from both sides head 9.
Shown in Figure 3: elasticity malleation tube sealing folder 4 is for closing up state after the extruding, and elasticity malleation tube sealing folder 4 is sleeved on the tube for transfusion 3, passes in the perforation 5 of tube for transfusion 3 by the both sides, front and back; Dop 8 extruding of upside are pressed in retaining bank 7; Constitute thus and go up lower plate 6, when driving folder, only need flicking to open folder head 9 once tube for transfusion 3 sealed condition; Retaining bank 7 promptly unclamps dop 8, and last lower plate 6 promptly flicks tube for transfusion 3 conductings.
When implementing this programme; Said elasticity malleation tube sealing folder 4 can adopt plastics one-shot forming processing, and front and back curved arc structure and the thickness of clamp are even, because the closing up block and unclamp all the stable generation elastic force through front and back curved arc structure of elasticity malleation tube sealing folder 4; When installing and using; Only need cover to pack into and get final product on the tube for transfusion 3 of remaining needle, when specifically using, elasticity malleation tube sealing press from both sides 4 should be positioned at tube for transfusion 3 as far as possible syringe needle 1 one ends be good.
