Abstract
A novel blood sampling pen comprises a main pen and a pen head, wherein the main pen comprises an outer sleeve, an inner sleeve, a core rod, a tail cap, an emission spring and a return spring. A first elastic arm is arranged lateral side of the core rod, the front end of the first elastic arm is provided with a first clamping hook, and a bayonet is arranged on the sidewall of the inner sleeve. The main pen further comprises an emission button. The novel blood sampling pen is characterized in that a flange is arranged on the inner sleeve close to the front end portion, and the portion on the rear end of the flange is inserted in from the front end of the outer sleeve to form a sliding connection with the outer sleeve. The inner wall of the outer sleeve is provided with a radial separator plate at the rear end of the inner sleeve, the emission spring is installed in the inner sleeve, and the return spring is installed in a space formed by the rear end of the radial separator plate and the front end of the tail cap. An emission button installing hole is arranged on the sidewall of the outer sleeve. The blood sampling pen simplifies the tail cap structure and omits a plurality of separation blades arranged on the core rod, thereby reducing the manufacture cost and assembly cost. The inner sleeve is in slide connection with the outer sleeve, and the compression of the emission spring is realized by pulling the outer sleeve rearward. The connection structure greatly shortens the length of the pen.

The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-2, a kind of Novel blood-collecting pen, forms by chief editor 1 and with its detachable nib being connected 2.Nib is referring to the nib structure of existing blood collecting pen.Described chief editor comprises overcoat 11, inner sleeve 12, be installed on the core bar 13, the tail cap 14 being connected with core bar rear end that are slidably connected with it in inner sleeve, be sleeved on transmitting spring 15 and return spring 16 on core bar.The front end that is provided with the first elastic arm 131, the first elastic arms at the sidepiece of core bar is provided with the first grab 132, and the sidewall of described inner sleeve is provided with and the first grab forms the friction tight bayonet socket of lock, and described chief editor also comprises can make the first grab depart from the firing button 17 of bayonet socket.The position putting in described near front end is provided with flange 121, and the rear end part that inner sleeve is positioned at flange inserts from the front end of overcoat, and itself and overcoat form and be slidably connected.Concrete, on the lateral surface of inner sleeve, be provided with on the medial surface of overcoat guide protrusions and the gathering sill matching, by guide protrusions, coordinate with the plug-in mounting of gathering sill, while having guaranteed that overcoat relatively moves along inner sleeve, there is not deflection along the circumferential direction.On the inwall of overcoat, be provided with radially dividing plate 18, described radially dividing plate is positioned at the rear end of inner sleeve.Radially dividing plate and overcoat can adopt integrated formed structure, or after minute body formed, dividing plate are fixed on outer casing inner wall.Described transmitting spring fitting is in inner sleeve, and described return spring is installed in the space that radially rear end of dividing plate and the front end of tail cap form.Concrete, when transmitting spring is during in impaction state, its front and back end be pressed on respectively on the circular bead surface on core bar and the inner face of inner sleeve bottom on; When return spring is during in impaction state, its front/rear end is pressed on respectively radially on the rear end face of dividing plate and the front end face of tail cap.The sidewall of described overcoat is provided with firing button installing hole 111, and described firing button installing hole is communicated with the front end face of overcoat.
In technique scheme, the bayonet socket putting in being located at and firing button can adopt following structure with being connected of inner sleeve: the sidewall of described inner sleeve is provided with the second elastic arm 122, the front end of the second elastic arm is provided with opening 123, and the rear end face of described opening and flange forms described bayonet socket.On described the second elastic arm, at opening, be provided with outer lug 124, described firing button is installed in described outer lug.Adopt said structure, when pressing firing button downwards, firing button drives the second elastic arm inwardly to swing, the first elastic arm that the second elastic arm presses on core bar then inwardly swings, when the front end face of the first grab and the rear end face of inner sleeve flange disengage, under the effect of transmitting spring, core bar is excited, the disposable blood taking needle 3 that drive is inserted into its front end moves ahead fast, penetrates in patient's finger abdomen, completes blood sampling.
In said structure, the syndeton of core bar rear end and tail cap is: the outside, end that the rear end of described core bar is provided with 133, two the 3rd elastic arms of two the 3rd elastic arms that are arranged symmetrically is equipped with the second grab 134.In described tail cap, be provided with toroidal cavity 141, the front end of tail cap is provided with the slotted hole 142 being communicated with toroidal cavity, and the length of described slotted hole is less than the diameter of toroidal cavity.Described two the 3rd elastic arms through the second grab dogging of its end after described slotted hole on the front end face of toroidal cavity.Core bar rear end and tail cap adopt above-mentioned syndeton, can complete as follows both assemblings: first the lateral surface at two the 3rd elastic arms applies inside pressure simultaneously, make two elastic arms that inside strain occur, then the slotted hole that the tail end of two the 3rd elastic arms is passed to tail cap front end enters in toroidal cavity the second grab of both sides, and finally release applies two pressure on the 3rd elastic arm and can complete assembling.This syndeton is than existing syndeton, has simplified structure, easy to assemblyly saves time and be connected reliable advantage.
The operating process of carrying out tip blood sampling with this blood collecting pen is:
The first step: hold tight nib for one, another is held tight overcoat, and pulls back overcoat, overcoat moves after driving core bar, makes to launch spring in compressive state;
Second step: unload nib;
The 3rd step: disposable blood taking needle is inserted into the front end of core bar,
The 4th step: again nib is arranged on chief editor;
The 5th step: make written front end face and refer to side grafting after touch, press firing button, the first elastic arm on core bar is inwardly swung, the constraint of the bayonet socket putting in disengaging to it, now under the effect of transmitting spring, core bar drives disposable blood taking needle reach, and thrusts finger abdomen by written front aperture.In the proal process of core bar, return spring is compressed, and when syringe needle penetrates into after certain depth, under the effect of return spring, core bar moves after driving disposable blood taking needle, the needle point of disposable blood taking needle is returned in nib, thereby complete whole blood collection procedure;
The 6th step: again unload nib, will directly pull up and throw away with the disposable blood taking needle of crossing.
