具体实施方式 Detailed ways

[0032] 如图1〜7所示的一种带有护套的收纳式安全护针器,包括有注射器针头1,在注射器针头1上套设有塑胶壳2。 [0032] A housing as shown in FIG. 1~7 safety sheath with the needle guard, including a syringe needle, syringe needle cover 1 is provided with a plastic shell 2. 同时,在塑胶壳2的一侧设有供注射器针头1出入的针头通 Meanwhile, at a side of the plastic housing 2 is provided with a needle for the syringe needle through and out 1

4孔3,塑胶壳2的另一侧设有注射器连接端口4。 4 hole 3, the other side of the plastic shell 2 is provided with a syringe port 4. 塑胶壳2内靠近针头通孔3处分布有浮动垫圈5,该浮动垫圈5上设有止位垫圈瓣6。 Plastic shell 2 close to the needle through-holes 3 distributed floating washer 5, flap 6 is provided with the stopping washer 5 on the floating gasket. 并且,所塑胶壳2与注射器针头1之间设有聚酯薄膜带9,其与众不同之处在于:塑胶壳2设有针头通孔3的一端设有衔接管,所述的延伸管上设有针管护套部件。 Further, the plastic shell 2 and the syringe needle is provided between a polyester film tape 9, which is distinctive in that: one end of the plastic housing 2 is provided with a through hole of the needle tube 3 is provided with engagement of the upper extension tube needle guard member is provided.

[0033] 如图1所示,结合本发明一较佳的实施方式来看,针管护套部件包括有护板7,护板7上延伸有护针套8。 [0033], in conjunction with a preferred embodiment of the present invention is shown in FIG. 1 view, the needle guard member comprises a guard plate 7 extends needle shield 8 on the shield 7. 同时,在护板7上设有连接孔,连接孔与所述衔接管相连接。 Meanwhile, a connection hole is provided on the protective plate 7, connection holes connected to the adapter tube. 这样, 当注射器针头1顺延塑胶壳2回缩的整个过程中,针尖部位能够完全处在护针套8内。 Thus, when the entire process is postponed a syringe needle retraction plastic shell 2, the tip portion can be well within the needle shield 8.

[0034] 进一步来看,如图5所示:聚酯薄膜带9分布有翻折单元10,翻折单元10之间呈波纹状连接。 [0034] Further view, as shown in Figure 5: the distribution of Mylar tape 9 flanging unit 10, connected between the corrugated section 10 folded. 同时,翻折单元10上设置有穿孔11,本发明所采用的注射器针头1穿过穿孔11。 At the same time, provided with perforations 11 on the folding unit 10, the syringe needle is used in the present invention 1 through perforations 11. 考虑到聚酯薄膜带9在注射器针头1与塑胶壳2之间起到承接作用,聚酯薄膜带9的一端连接浮动垫圈5,聚酯薄膜带9的另一端设有套圈12,套圈12与供注射器针头1相连。 Considering the Mylar tape 9 plays the role of receiving a syringe needle and between the plastic shell 2, one end of the Mylar tape 9 is connected to the floating washer 5, the other end of the polyester film tape 9 is provided with a collar 12, the collar 1 and 12 for the syringe needle is connected. 进一步来看,考虑到注射器针头1能够在针头穿孔11的导向下顺畅移动,本发明的针头穿孔11可以为圆孔,令圆孔的直径大于或是等于注射器针头1的直径,能够起到较佳的效果。 Further view, taking into account the syringe needle 1 can move smoothly in the guide 11 of the piercing needle, the needle of the present invention may be circular perforations 11, so that the circular hole is greater than or equal to the diameter of the diameter of a syringe needle, it can play a more good results.

[0035] 并且,结合图2、图3来看,考虑到能够对针尖收纳后的前进方向进行一个有效止位,止位垫圈瓣6至少有两片,浮动垫圈5为默认状态时,止位垫圈瓣6之间设有开口,当本发明处于注射使用状态时,聚酯薄膜带9对止位垫圈瓣6施加一定的力,令止位垫圈瓣6之间设有的开口可容纳注射器针头1出入。 [0035] and, in conjunction with FIG. 2, FIG. 3 view, taking into account a possible effectively stopping the advancing direction of the needle housing, stopping washer having at least two flaps 6, floating washer 5 to the default state, stopping 6 is provided with an opening between the valve gasket when the present invention is used in the injection state, nine pairs of mylar tape flap stopping application of constant force washer 6, so that the stopping washer 6 between the flap is provided with an opening that can accommodate a syringe needle 1 out.

[0036] 再进一步来,为了有利于本发明在使用初始状态注射器针头1能够与塑胶壳2进行一个较为稳定的结合,注射器连接端口4内设有凹槽13,注射器针头1底座的前端设有与凹槽13对应的齿条14。 [0036] Still further, the present invention in order to facilitate the use of the initial state can be a syringe needle a plastic shell 2 and a more stable binding, a syringe port 4 is provided with a recess 13, the front end of the base 1 is provided with syringe needle corresponding to the groove 13 of the rack 14. 当然,结合本发明一较佳的实施方式来看,所述的齿条14至少有四个,呈十字状分布在注射器针头1底座的前端,注射器连接端口4内亦设有对应的四个凹槽13。 Of course, in conjunction with a preferred embodiment of the present invention point of view, the rack 14 has at least four, distributed in the form of cross-shaped distal end syringe needle base 1, the syringe also has a connection port corresponding to the four recesses 4 slot 13. 这样,在初始使用状态时不会出现塑胶壳2松动而影响注射的效果。 Thus, the plastic shell 2 Injection loosening effect does not occur in the initial state of use.

[0037] 并且,结合实际来看,聚酯薄膜带9的宽度为7. 6毫米、厚度为0. 10毫米,洞足以容纳注射器针头1。 [0037] Further, the actual point of view, the width of Mylar tape 9 is 7.6 mm, a thickness of 0.10 mm, a hole large enough to accommodate syringe needle. 该容纳注射器针头1可以承受住胜过6. 8公斤的力量。 The receiving syringe needle 1 can withstand better than 6.8 kilograms of force. 当然,考虑到制造时组装的便捷,同时满足浮动垫圈5能否较好的设置在塑胶壳2内,所述的浮动垫圈5外围分布有卡点凸起15,卡点凸起15与塑胶壳2内壁相接触,由此来增大摩擦力。 Of course, when assembled in consideration of manufacturing convenience, can simultaneously satisfies the floating gasket 5 preferably disposed in the plastic housing 2, the floating washer 5 cards are distributed peripheral projection points 15, 15 and the projection point card plastic shell contacting inner wall, thereby increasing the friction. 为了收纳浮动垫圈5,可以在塑胶壳2内靠近针头通孔3处分布有卡槽16,所述的卡槽16内设有浮动垫圈5。 5 in order to accommodate the floating washer, the needle may close a through hole in the plastic housing 2 has three distribution slot 16, slot 16 of the gasket 5 is equipped with floating.

[0038] 结合本发明的使用来看,在现有的注射中往往需要将一些液态的药剂与粉末状的药剂进行混合,形成一种混合溶液后一同注射,因此存在一个液体转移的过程。 [0038] The present invention is used in conjunction with the point of view, some of the liquid medicament will often need the powdered medicament in a conventional injection were mixed to form an injection solution mixed with the latter, there is a liquid transfer process. 比如,将处于图6状态中的护套式注射器针头1用安全护针器插入盛放液态药剂的容器中抽取液体。 For example, in the state of FIG. 6 in the syringe needle sheath is inserted into a container accommodating a liquid drug safety needle guard in a liquid extract. 之后注入盛放粉末状药剂的容器。 After the powdered medicament container accommodating injection. 最后抽取混合液进行注射。 Finally, the mixture extracted for injection. 在此期间,由于针管护套部件的存在,不会出现抽针管带出容器瓶塞上的物质,确保了注射安全。 During this period, due to the presence of the needle guard member, the needle will not be drawn out of the cork in the container material, to ensure the safety injection.

[0039] 再进一步来看,一旦给病人输送完预定剂量后,在即将要把注射器针头1从病人身上抽出时。 [0039] Still further point of view, once the predetermined dose to the patient conveyor finished, when the syringe needle is about to make a withdrawal from the patient. 使用者将塑胶壳2往注射部位推进,移动到病人的皮肤边。 The plastic shell 2 a user to advance the injection site, is moved to the side of the patient's skin. 之后,继续抽出注射器针头1,令针尖从病人皮肤中回缩进入塑胶壳2中。 After that, we continue out of syringe needle 1, so that the tip is retracted from the patient's skin into the plastic shell in 2. 同时,在这个过程中,由于注射器针头1的针管外设置有护针套8,注射后针管所可能附带的污染物均在护针套8内,特别是针尖完全被护针套8收纳,不会在收纳过程中出现意外刺穿使用者的情况,实现了第一个防污染保险。 Meanwhile, in the process, since the outer needle syringe needle 1 is provided with a needle shield 8, the injection after the needle tube may be included contaminants are within the needle shield 8, particularly the needle tip fully needle shield 8 receiving, not there will be accidental puncture of the user in the storage process, we achieved the first anti-pollution insurance. [0040] 一旦给病人输送完预定剂量后,在即将要把注射器针头1从病人身上抽出时。 [0040] Once the predetermined dose to the patient conveyor finished, when the syringe needle is about to make a withdrawal from the patient. 使用者将塑胶壳2往注射部位推进,令护针套8包裹注射器针头1。 The plastic shell 2 a user to advance the injection site, the needle guard sleeve 8 so that the parcel 1 syringe needle. 接着,通过聚酯薄膜带9 的弹性引导,令塑胶壳2顺延注射器针头1移向针尖。 Next, the elastic guide 9 by a Mylar tape, plastic shell 2 so that a syringe needle toward the needle tip extended. 具体来说,当针尖回缩到针尖容纳空间时,聚酯薄膜带9施加在浮动垫圈5的止位垫圈瓣6的力逐渐减少,止位垫圈瓣6逐渐恢复到原先的闭合状态,针尖无法再次伸出,可将针尖密封在塑胶壳2内的容纳空间中。 Specifically, when the needle tip is retracted into the receiving space 9 is applied to a polyester film with a floating gasket plate 5 forces the stopping of the washer 6 is reduced gradually stopping washer valve 6 gradually restored to the original closed state, the needle tip can not be again projecting needle tip may be sealed within the receiving space in the plastic housing 2. 由于聚酯薄膜带9的翻折单元10之间的波纹状间隔一定,塑胶壳2亦不会在聚酯薄膜带9的作用下过分前行,确保了针尖的有效收纳,实现了第二个防污染保险,最终如图7所示。 Since the Mylar tape folded corrugated unit 9 the spacing 10 between the constant plastic shell 2 is also not excessively forward under the action of a Mylar tape 9 ensures efficient storage tip, to achieve a second Insurance pollution, eventually as shown in FIG.

[0041] 通过上述的文字表述并结合附图可以看出,采用本发明后,通过塑胶壳与针管护套部件的配合,在完成注射后首先可以对针管附带的污染物进行有效隔离。 [0041] expressed by the above character in conjunction with the drawings can be seen, the present invention, first isolation can be effectively included with the needle after completion of injection of contaminants through the plastic housing fitting member and the needle guard. 同时,通过塑胶壳与聚酯薄膜带的配合,在完成注射后能对针头进行完全的收纳,有效确保已使用的注射器针头不会污染外部环境。 Meanwhile, after completion of the injection can be performed to complete the housing with the needle through the plastic housing with a Mylar tape, the syringe needle has been used effectively to ensure that does not contaminate the outside environment. 更为重要的是可以防止已使用过的注射器针头意外刺穿人员, 杜绝这种危险的疾病传播途径。 More importantly, can prevent a used syringe needle accidentally pierced staff, put an end to this dangerous disease transmission.

[0042] 当然,以上仅是本发明的具体应用范例,对本发明的保护范围不构成任何限制。 [0042] Of course, these are only examples of specific application of the present invention, the scope of protection of the present invention does not constitute any limitation. 除上述实施例外,本发明还可以有其它实施方式。 In addition to the above-described embodiment exceptions, the present invention is capable of other embodiments. 凡采用等同替换或等效变换形成的技术方案,均落在本发明所要求保护的范围之内。 Where the use of equivalent replacement or equivalent transformation formed aspect, the present invention all fall within the scope of the claims.
