Abstract
The utility model discloses a needle head for limiting and preventing the inserting needle of a disposable infusion set from shifting. The needle head comprises a needle stalk and a handle vertically connected to the rear end of the needle stalk, wherein a small guide plate is integrally arranged between the handle and the needle stalk; and a limiting sleeve is sleeved on the needle stalk. The needle head of the utility model has the advantages of reasonable design and simple structure, and is capable of effectively limiting the length of the inserting needle when conducting the intravenous infusion; and the needle head working with a needle head shifting prevention frame can further prevent the needle from escaping, thus preventing the blood vessels of patients from being injured and relieving the pain of the patients in the treatment.
Description
Technical field
This utility model belongs to clinical treatment equipment technical field, is specifically related to a kind of disposable infusion set inserting needle qualification and anti-moving syringe needle.
Background technology
When clinical vein was infused, the length of inserting needle was long more, and the pin stalk is big more to the mechanical irritation and the damaged area of blood vessel wall, degree of injury is serious more, and blood constituent oozes out and increases, and blood vessel congestion is obvious, cause and conclude hamartoplasia, vessel wall thickening, hardening, tube chamber diminishes or is inaccessible.Because vascular endothelial cell is destroyed, easily secondary thrombus forms and occluding vascular.Needling length is short more, and the above-mentioned pathological change of blood vessel is just light more.Therefore, when venous transfusion,, determine that pin stalk in blood vessel, obtains at syringe needle under the prerequisite of firm fixation, should reduce the length that entering the intravenous needles stalk as far as possible when the puncture blood back.The pain that this not only can alleviate patient alleviates the damage to blood vessel, and particularly for the patient of the long-term transfusion of needs, the service life, the phlebitic generation of prevention that prolong its blood vessel all have crucial effect.
The length of inserting needle should be followed following principle during venous transfusion: behind the puncture blood back, reduce entering intravenous pin stalk length under the prerequisite of secure fixation as far as possible.And the problem that existing syringe needle for transfusion device structure exists just the unqualified and syringe needle of needling length be difficult to firm fixation.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of reasonable in design, simple in structure, needling length and can prevent that the disposable infusion set inserting needle that runs pin from limiting and anti-moving syringe needle in the time of limiting the venous transfusion operation effectively is provided.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of disposable infusion set inserting needle limits and anti-moving syringe needle, comprise the pin stalk and be vertically connected at the handle that pin obstructs the rear end, it is characterized in that: be wholely set little guide plate between described handle and the pin stalk, be set with limit casing on the pin stalk.
Its length direction is provided with a guide groove in the limit casing upper edge, is provided with the locating hole that is used for the little guide plate of clamping at the guide groove middle part.
Also be provided with handgrip on the described limit casing.
This utility model compared with prior art has the following advantages:
(1) rationally novel in design, simple in structure, easy to operate;
(2) can determine and limit the needling length of medical worker when venous transfusion is operated effectively, thereby reduce the damage that patient's blood vessel is caused to greatest extent;
(3) be used with " the anti-moving frame of disposable use intravenous drip syringe needle " (hereinafter to be referred as the anti-moving frame of syringe needle, number of patent application 200920033387.5), in infusion process, can play firm fixation syringe needle;
(4) patient and medical personnel's thought pressure and labor intensity have been alleviated.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of this utility model limit casing.
Description of reference numerals:
1-pin stalk; 2-hands handle; The little guide plate of 3-; The 4-limit casing;
The 5-guide groove; The 6-locating hole; The 7-handgrip.
The specific embodiment
As shown in Figure 1, this utility model comprises pin stalk 1 and is vertically connected at the handle 2 that pin obstructs 1 rear end, has been wholely set little guide plate 3 between described handle 2 and the pin stalk 1, is set with limit casing 4 on the pin stalk 1.
As shown in Figure 2, its length direction is provided with a guide groove 5 in limit casing 4 upper edges, is provided with the locating hole 6 that is used for the little guide plate 3 of clamping at guide groove 5 middle parts.
Also be provided with handgrip 7 on the described limit casing 4.
Operation principle of the present utility model is as follows:
The length of setting pin stalk 1 is L, and its reasonable needling length is single factor optimal selection problem, and through practice and a large amount of the observation, needling length preferably is suitable and meets venous transfusion reality at 0.618L.
This utility model limit casing 4 passes pin stalk 1, and little guide plate 3 enters in the locating hole 6 by guide groove 5, and pin obstructs 1 extension elongation and is positioned in 0.618L, makes needling length obtain preferred and qualification.
The 5 wide combining abilitys of the thickness of the little guide plate 3 of this utility model and guide groove can overcome the puncture force of needle point to blood vessel, and the front end that little guide plate 3 drives limit casings 4 snaps in the door shape hole clipping of the anti-moving frame of syringe needle, and syringe needle is fixed, and plays anti-action and uses.If meet the front end of limit casing 4 when not entering in the door shape hole clipping of the anti-moving frame of syringe needle fully, can promote handgrip 7, it is all entered.
This utility model also has the function of meticulous adjusting needling length.Its way is to pinch handgrip 7, and moving handle 2 can carry out the meticulous adjustment (generally need not to do like this) of needling length.Before being pushed into, handle 2 can make pin stalk 1 expose greatest length (being approximately equal to L-5mm).
