Description
Technical field
The present invention relates to a kind ofly for carrying out from the puncture auxiliary device of health blood drawing, described puncture auxiliary device comprises: at least one lancet; The lancet holding element that at least one is connected with lancet, its in the enclosure section at forward be movable oppositely; And executive component, it is used at least one spring element is operated and/or pre-tensioner, and spring element is suitable for the lancet holding element is applied elastic force, and preamble according to claim 1 is described.
Background technology
The puncture auxiliary device has the variant of One's name is legion, wherein can use mention in the first row above this for the puncture auxiliary device from the human body blood drawing, and this blood is verified by means of hemanalysis subsequently.In addition, so-called disposable puncture auxiliary device is known, and this disposable puncture auxiliary device is for disposable and design.Therefore, this disposable puncture auxiliary device is for following and design, and namely lancet or pin are replaced and reusing of this puncture auxiliary device occur subsequently.
In the different variants of this disposable puncture auxiliary device, a kind of differentiation of carrying out according to trigger mechanism is for example arranged.In this case, can activate in the side, distinguish between back side activation and contact activation or the positive disposable puncture auxiliary device that activates.Therefore, trigger mechanism and executive component can be attached to side, the back side or front on the shell of puncture auxiliary device, wherein setting up of front can be substituted by a kind of mechanism, what this mechanism allowed is, when the auxiliary device that will puncture was positioned on skin, the contact under pressure applies caused that the triggering of lancet is used for piercing process subsequently.
Equally, this disposable puncture auxiliary device (SUD) can be divided into pre-tensioned puncture auxiliary device and non-pre-tensioned puncture auxiliary device, for pre-tensioned puncture auxiliary device, but position spring element in the inner has been applied in the elastic force of preset when paying and offering user/patient, for non-pre-tensioned puncture auxiliary device, spring element can only apply elastic force by user/patient.
In this case, spring element not only can be made of plastics, and can be made of metal, and has various shape, for example spiral type, sinusoidal or analogous shape.
The blood drawing element that is used for skin penetrating using for example can use various difform pins, intubate or cutter.
In addition, so-called non-guided puncture auxiliary device is known.In this case, there is no to be used for pre-determining at the piercing process of reality the sliding guidance of guide rail, in piercing process, lancet should be discharged shell the short time and again be moved into subsequently shell.Exactly, by use the elastic force of spring element for this reason, with lancet preferably translation together with the lancet holding element, that is to say that linearity shifts out and move into again.In this case, occur in lancet and discharge during shell that the short time of spring element excessively swings and spring element is towards the reply of its resting position subsequently, in this resting position, lancet should be hidden in the enclosure again.
For this non-guided puncture auxiliary device disadvantageously, piercing process occurs after, spring element accelerates the lancet oriented opposite by elastic force, even therefore again hiding in the enclosure the time when lancet, also still has the dump energy of spring element.As a result, the lancet holding element collides the backstop of the spring element that is positioned at its back together with lancet, and spring element shifts out shell again under the retroaction that the lancet holding element carries out together with lancet.
Discharge shell again this and that do not expect to have can occur in frequent succession.
This reach again of the lancet after the actual first piercing process that carries out does not expect to have, and cause the pain that patient or user are subject to increase, and there is the danger of haveing no alternative but lancet is thrust for the second time another skin position of moving due to the puncture auxiliary device.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of puncture auxiliary device for drawing blood from health by means of the lancet execution, described puncture auxiliary device can be eliminated lancet as so-called disposable puncture auxiliary device and repeatedly thrusts the dangerous of skin and make consequent pain minimum.
Above-mentioned purpose is that according to claim 1 feature reaches.
The more important of the present invention is, a kind of for carrying out from the puncture auxiliary device of health blood drawing, described puncture auxiliary device comprises: at least one lancet; The lancet holding element that at least one is connected with lancet, its in the enclosure section at forward be movable oppositely; And executive component, it is used at least one spring element is operated and/or pre-tensioner, spring element is suitable for the lancet holding element is applied elastic force, at spring element or/and dispose outstanding element on the lancet holding element, outstanding element is deflectable with respect to the lancet holding element when the lancet holding element moves on oppositely, so that damping should motion.By what this outstanding element can advantageously be realized be, make the motion on oppositely together with lancet of spring element and lancet holding element be subject to damping, therefore advantageously can not make twice of lancet, shift out shell three times or four times.Can avoid thus owing to repeatedly shifting out lancet and repeatedly thrusting the further pain that produces in patient skin.
By what can guarantee as this outstanding element of damping element be equally, the puncture auxiliary device has the high reliability in its use, only once and subsequently moves into again shell because lancet is discharged shell.
This according to puncture auxiliary device of the present invention disposable puncture auxiliary device preferably, that is to say to be considered to for disposable, and be delivered to user or patient under non-pre-tensioner state.
Preferably, outstanding element is flexible tab element, the first end of tab element with spring element or/and the outside of lancet holding element be connected, the second free end of tab element at least one first guide rail section along at least one guide rail under the first case of bending of tab element is slidably, and at least one second guide rail section along at least one guide rail is slidably under the second case of bending of tab element.In this case, guide rail preferably is configured in the outside at least one wedge shape protuberance, wherein, protuberance with executive component or/and shell be connected.
Dispose an angle between the first guide rail section of wedge shape protuberance and the second guide rail section, the scope of this angle is 5 °-70 °, is preferably 25 °-55 °.
By be configured in guide rail section and tab element on the wedge shape protuberance this cooperate realize be, tab element almost together moves to below the outlet of enclosure under its first case of bending during lancet shifts out or front or to this outlet without resistance, and tab element deflects by the second guide rail section in heterodromous situation, and slide along having from the second guide rail section of the first different orientations of guide rail section under its second case of bending, and also therefore damped by this second guide rail section braking on it is reverse.Thus, not only tab element, and spring element and lancet holding element are braked together with lancet.
This braking is not to occur suddenly due to the use of the track of the second guide rail section and tab element, therefore in the opposite direction, namely do not falling back forward, and the lancet holding element can be not again together with lancet in the front side outlet from shell discharge.This is that flexible or elastic structure due to tab element realizes, tab element buckles by the second guide rail section, brakes with regard to the oriented opposite motion to spring element and lancet holding element.
So long time occurs in this bending, until tab element is located on the second guide rail section substantially with first end, and the oriented opposite motion of lancet holding element and spring element is stopped fully.
Preferably, the first case of bending is toward the clockwise direction or the counterclockwise directed bending of tab element, and the second case of bending is the oppositely oriented bending of tab element.What can realize thus is, disposes an angle between the first guide rail section and the second guide rail section, thus tab element bending left once and bending to the right once.
Spring element is configured in after the lancet holding element with respect to the puncture direction of puncture auxiliary device and before the each several part of executive component or on each several part.These parts flexibly interconnect and realize a kind of simple and uncomplicated structure by spring element.
Spring element not only can be made so that the plastics spring form is S-shaped, and can adopt equally plastics or adopt metal to make twist.
According to a preferred implementation, tab element is moving along the first guide rail section during pre-tensioner process and during the piercing process of forward orientation, and slides along the second guide rail section between moving period in the oriented opposite of lancet holding element.Alternatively, this tab element also can be roll-type or similar fashion is moved on guide rail section.

The specific embodiment
Fig. 1 illustrates according to the puncture auxiliary device of an embodiment of the invention under tensioning state not, that is to say the triggering of puncture auxiliary device and pre-tensioner before axonometric chart.Puncture auxiliary device 1 has shell 2, and shell 2 can make lancet 3 discharge in outlet at downside or front side.
Under this state, although executive component is imported in shell 2, also do not stand the pre-tensioner of plastics spring.This only have when executive component 4 further be pushed in the shell and the tooth section of the corresponding complementary that is engaged to shell 2 by means of the outstanding laterally tooth 6a of section and 6b or recess in just generation, tooth section or the recess of this corresponding complementary are not shown here.Therefore occur pre-tensioner along with the campaign of promotion for the first time of executive component 4.
Along with promoting for the second time motion, the triggering carried out by means of the lancet holding element occurs and the lancet holding element that carries out by means of the spring element that is applied in elastic force in the application of force of puncture direction.In this case, actual trigger process is to be undertaken by two inclined-planes that are attached on executive component, and two maintenance forearms that are used for the correspondence of maintenance lancet receiver member are separated transverse to the puncture direction, in order to discharge the lancet receiver member in the puncture direction thus.
By what for example this engaging of the executive component that carries out by means of the tooth 6a of section and 6b and 6c and 6d shown in Figure 2 and shell 2 can be guaranteed be, in the situation that this disposable puncture auxiliary device can not recycle, because according to shown in Figure 2, these teeth sections can not throw off automatically with the tooth 10a of section and the 10b of complementary structure again.Therefore, the lasting engaging of executive component 4 and shell 2 occurs after piercing process triggers and after piercing process finishes, this has stoped the again pre-tensioner and again operate of the auxiliary device that punctures.
Fig. 2 illustrates the cross-sectional view of puncture auxiliary device according to the embodiment of the present invention.As can be seen from this figure, lancet holding element 7 with the configuration within it lancet and sterile protector 3a together with in the translational motion mode, that is to say it is extensible downwards.This is by the direction of arrow 8 expressions.Occur subsequently to make lancet 3 hidden in shell 2 again according to the motion of the oriented opposite shown in arrow 9.
Can clearly find out from this figure, lancet holding element 7 is fixedly connected with the end 5b of spring element 5 at distolateral end 7a with the U-shaped shape.The other end 5a of spring 5 is connected with executive component 4 like this at upside, and namely executive component 4 preferably generates from common injection moulding process.
Dispose the tab element 15 of preferably making in common injection moulding process in the side of S shape spring element 5, this tab element 15 is configured on the curved section of S shape spring element 5 with first end 15a.Flexible and elastic tab element 15 is counterclockwise or clockwise freely relatively swingable with its free end 15b, that is to say that what see at drawing is swingable to the left or to the right.Therefore, free end 15b to the right directed certain crooked pre-tensioner under, be movable along the first guide rail section 12.This occurs during the forward directed movement 8 of spring element 5 and lancet holding element 7.
During the forward directed movement and when oriented opposite is subsequently moved, pre-tensioner due to what stand, occur in tab element 15 motion left of seeing drawing from the passing through of the point of wedge shape protuberance 11, and through over-angle 14 motions, angle 14 is comprised by wedge-shaped element 11 free end 15b from right to left.In case the adverse movement 9 of lancet holding element and spring element occurs due to counteractive elastic force after having carried out from the outlet of shell 2 at lancet discharging, tab element 15 this moment is with regard to not along the first guide rail section 12 and along the second guide rail section 13 deflection left, and counterclockwise standing pre-tensionerly along the slip of the second guide rail section 13 by free end 15, the second guide rail section 13 tilts with respect to the first guide rail section 12 with angle 14 and stretches left.
This wedge-shaped element 11 also can be present in the right side as shown in the figure, yet needn't use by means of tab element simultaneously, and this tab element does not illustrate as another element at this.Exactly, be created in thus certain independence of the installation aspect of the part that will install.
Especially as shown in Figure 3, and shown in the enlarged drawing of Fig. 4, the deflection of the free end 15b by tab element, spring element 5 moves up again or moves into, and tab element 15 is just crooked left.Thus, occur between moving period oriented opposite speed and the damping of acceleration if possible in oriented opposite.
This so long time of Speed Reduction generation of utilizing damping action to carry out is until the free end 15b of tab element 15 has reached the height of angle 14 and can further not move up again.Stop at a position at this moment spring element, almost or fully be in its resting position at this position spring element.Do not occur due to the damping action of tab element 15 during the slip of the second guide rail section 13 lancet again shift out and spring element and lancet holding element 7 take the shifting out as condition of falling back.
Fig. 4 illustrates the sectional view according to the each several part of puncture auxiliary device of the present invention again.During the adverse movement of lancet and spring element 5 is carried out or afterwards, sting device is under this state.
Can also clearly find out in the figure, the free end 15b of tab element 15 has the inclined-plane in the front equally, in order to can more easily slide along the second guide rail section 13.On the contrary, free end 15b only slides on the first guide rail section with minor apex face.
Advantageously, due to tab element when damped with cooperating of the second guide rail section 13, spring element 5 still has certain residue spring energy in its spring system after spring element and lancet holding element 7 have carried out adverse movement.This dump energy has been passed through the tab element of damping action during retracting, along with this tab element reduces along the slip of the second guide rail section 13.This has been avoided lancet repeatedly to discharge shell.
Obviously, it is also conceivable that the another location except the back side that executive component is configured in the puncture auxiliary device.Can consider equally to use other spring elements or more spring element.
As long as disclosed whole features in present specification in independent mode or compared with prior art novel with compound mode, are just key characters of the present invention by advocating.
