Description
本發明係有關於一種安全針具,特別是指其為一種旋轉回縮式安全針具。The invention relates to a safety needle, in particular to a safety retractable safety needle.
按; 護理人員的職責為給予病人護理照護,而給藥是護理照護中頻率最高且重要又不容錯誤的工作。給藥又分為給予口服藥物、注射藥物、點滴加藥等途徑,其中使用注射器給藥更是常見的醫療行為。Press; Nursing staff's responsibility is to give patient care, and drug delivery is the most frequent and important work that cannot be mistaken in nursing care. Administration is divided into oral medication, injectable medication, and drip infusion, among which the use of a syringe is a more common medical practice.
在護理人員龐大的人力及高使用率的注射醫療行為下,「針扎」(needlestick)意外的發生層出不窮。注射器在臨床上通稱為空針,空針的構造主要包含針頭、針筒、針心,其中,針頭由金屬製成,用於抽取藥物及注射藥物、及抽取血液時接觸病患的部分;針筒由塑膠製成,具有刻度檢視藥物劑量及手部握持部分;針心由塑膠及橡膠製成,用於回拉抽藥、推藥及抽血。Under the huge manpower of nurses and the high use rate of injection medical behavior, accidental occurrence of "needlestick" is endless. Syringes are commonly referred to as empty needles in clinical practice. The structure of empty needles mainly includes needles, syringes, and needle cores. Among them, the needles are made of metal and used to extract drugs and inject drugs, as well as the parts that come into contact with patients during blood extraction; needles The cylinder is made of plastic, which has a scale to check the dose of the drug and the part held by the hand; the needle core is made of plastic and rubber, which is used to pull back the medicine, push medicine and draw blood.
「針扎」是指護理人員於替病人執行注射醫療行為時,不慎將空針之針頭扎傷自身的意外,而發生針扎的針頭通常都已接觸過病患血液,感染B肝、C肝及愛滋病等血液傳染的疾病機率不可漠視,且針扎帶來的不只是生理上的危害,也會增加醫療資源的開銷及傷者、親友們的擔心與恐慌。從技職教育到醫療院所皆不斷宣導預防針扎及推廣預防針扎的教育課程,其中單手回套針頭蓋及針頭蓋不回套直接於針頭收集盒以扣拉方式脫針等預防針扎行為都無法完全避免針扎的發生。"Acupuncture" refers to the accident that the nursing staff accidentally punctured the needle of an empty needle while performing an injection medical treatment for a patient. The needle that has undergone the needle has usually contacted the patient's blood and infected the liver B, C The probability of blood-borne diseases such as liver and AIDS cannot be ignored, and acupuncture not only causes physical harm, but also increases the cost of medical resources and the worry and panic of the wounded, relatives and friends. From technical and vocational education to medical institutions, education on needle prevention and promotion of needle prevention has been continuously promoted. Among them, one-handed return of the needle cover and the needle cover are not returned directly to the needle collection box to prevent the needle from being removed by buckling. Acupuncture cannot completely avoid the occurrence of acupuncture.
近年來,安全針具的運用取代了傳統針具,但現有的的安全針具仍有諸多缺點:如無法更換針頭運用於不同用途、覆蓋針頭之啟動裝置操作不易或步驟繁瑣、覆蓋後針頭中段仍外露、拔針時安全針套尚未遮覆針頭,無法應用於低劑量注射、無法應用於非肌肉層的注射、覆蓋針頭的遮覆蓋為開口式軟塑膠等等。In recent years, the use of safety needles has replaced traditional needles, but the existing safety needles still have many disadvantages: if the needle cannot be replaced for different purposes, the starting device covering the needle is difficult to operate or the steps are complicated, and the middle part of the needle is covered It is still exposed, the safety needle cover has not covered the needle when the needle is pulled, and it cannot be used for low-dose injections, injections that are not applied to non-muscular layers, and the needle cover is covered with open-type soft plastic.
現有的的安全針具最主要的缺點是注射完藥物後的針頭從組織層拔出時針頭無遮覆,此現象就無法避免被針扎的危險性,上述缺點導致安全針具周全落實於醫院的困難。The main disadvantage of the existing safety needles is that the needles are not covered when the needles are pulled out of the tissue layer after the injection of the drug. This phenomenon cannot avoid the danger of being stuck. The above shortcomings lead to the thorough implementation of safety needles in hospitals. Difficulties.
接著敬請配合參閱附件,附件中照片顯示現有的安全針具,而以下為說明現有安全針具的缺點:Then please refer to the attachment, the photos in the attachment show the existing safety needles, and the following is to explain the disadvantages of the existing safety needles:
回拉折斷式:Pull back break type:
1.容錯性低,不適用vial 粉劑稀釋藥物用,多數vial 藥物為粉末狀,需先以蒸餾水稀釋後再抽取適量藥物,此時需要水全部注入,針心到底時即啟動針頭處理裝置而無法恢復。1. Low fault tolerance, do not use vial powder to dilute drugs. Most vial drugs are in powder form. You need to dilute with distilled water before extracting an appropriate amount of drugs. At this time, all the water needs to be injected. restore.
2.操作步驟複雜,注射後需回拉,讓針頭回縮到針筒內,折斷後段注射桿體再分類丟棄。2. The operation steps are complicated. After the injection, the needle needs to be pulled back to retract the needle into the syringe.
3.針頭針體採螺旋式接合,無法改以斜面增加針頭與藥劑接觸面,加速抽藥。3. Needle needle body adopts spiral connection, can not be changed to increase the contact surface of the needle with the bevel to accelerate the drug withdrawal.
4.注射接觸面拔針後才可進行針頭處理,易針扎。4. Needle treatment can only be performed after the needle is pulled on the injection contact surface, which is easy to puncture.
套筒旋轉式:Sleeve rotation:
1.操作步驟複雜,注射後需把保護套筒往前推,然後再向側邊卡止住,但保護套筒卡止處不夠牢固,容易滑脫,導致針扎。1. The operation steps are complicated. After the injection, the protective sleeve needs to be pushed forward and then locked to the side, but the locking point of the protective sleeve is not strong enough, and it is easy to slip off, resulting in needle sticking.
2.從注射接觸面拔針後才可進行針頭處理,易針扎。2. Needle treatment can only be performed after the needle is pulled out from the injection contact surface, which is easy to puncture.
彈簧回縮式:Spring retracted:
1.針具利用彈簧彈力使針頭反彈入針筒內,但彈簧後座力大,經常會嚇到病人。1. The needle uses the spring force to make the needle bounce into the syringe, but the spring recoil force is large, which often scares the patient.
2.針頭與針筒一體成形,無法更換針頭,不符合對高黏度藥物、或急救個案需更換較粗針頭的需求。2. The needle and the syringe are integrally formed, and the needle cannot be replaced, which does not meet the need for replacing thicker needles for high-viscosity drugs or emergency cases.
3.不適用vial 粉劑稀釋藥物用,因多數vial 藥物為粉末狀,需先以蒸餾水稀釋後再抽取適量藥物。本設計當蒸餾水完全注入後,針頭即內縮,無法使用,故需使用另一支空針抽藥及注射,增加成本。3. Vial powder is not suitable for diluting drugs. Because most vial drugs are in powder form, they need to be diluted with distilled water before taking appropriate amount of drugs. In this design, when the distilled water is completely injected, the needle is retracted and cannot be used. Therefore, another empty needle is needed to pump medicine and injection, which increases the cost.
4.塑膠加彈簧,製作成本較高。4. Plastic plus spring, higher production cost.
針頭壓蓋式:Needle gland type:
1.臨床最廣泛應用的安全針具,但壓蓋的握持部位不正確即有針扎的危險性。1. The most widely used safety needle in clinical practice, but there is a danger of needle sticking if the holding part of the gland is incorrect.
2.從接觸面拔針後才可進行針頭處理,易針扎。2. Needle treatment can be performed only after the needle is pulled out from the contact surface, which is easy to pierce.
3.壓蓋後,針頭中段有外顯的情況。3. After capping, the middle part of the needle is visible.
針頭半露式:Needle half exposed:
1.其針頭中端是外顯的,套體鬆動時也有針扎的可能性。1. The middle end of the needle is exposed, and there is also the possibility of needle sticking when the sleeve is loose.
2.需雙手併用:一手注射,一手處理側體護套。2. Both hands are required: one hand for injection and one hand for side body sheath.
3.若注射時因角度使針頭歪斜,易無法確實讓側體覆套蓋住針頭,容易針扎。3. If the needle is skewed due to the angle during injection, it is not easy to ensure that the side body cover covers the needle and it is easy to puncture.
本發明人研發的本發明旋轉回縮式安全針具以克服上述缺點為目的,兼具周延五性,如下列:The invented rotary retractable safety needle developed by the present inventor aims to overcome the above-mentioned shortcomings, and has the characteristics of five extensions, as follows:
1.安全覆蓋性:從組織層拔針時針頭已完全覆蓋避免針扎。1. Safe coverage: When the needle is pulled from the tissue layer, the needle is completely covered to avoid needle sticking.
2.針頭可換性:因應不同需要,可更換針頭。2. Needle exchangeability: According to different needs, the needle can be replaced.
3.容量可適性:適用於各種劑量。3. Capacity adaptability: suitable for various doses.
4.途徑可變性:適用於各種注射法。4. Path variability: applicable to various injection methods.
5.抽血可用性:適用於抽血。5. Blood drawing availability: suitable for blood drawing.
因此,設計一種常態下不會遮擋注射器之針頭,以便針頭注射,而當注射器之針頭結束注射後,針頭能全部縮入隱藏,以預防針扎情形之安全針具,實為吾人亟其所需。Therefore, to design a safety needle that will not cover the needle of the syringe in order to allow the needle to be injected.
