實際操作時，當該推桿4朝該收束段21滑移且該卡扣部43***該卡扣槽311中時，該卡扣部43係與該卡扣槽311相卡掣，待注射液排出作注射後，藉以可透過該推頂件42將該針具組3拉入該注射筒2中。該轉接頭31朝向該推桿4之一端設有一凸柱36，當該卡扣部43與該卡扣槽311相卡掣時，該轉接頭31之凸柱36可抵壓於該推桿4之該彈性活塞41，連帶使該轉接頭31與該針頭33作偏向，使該轉接頭31與針具停留於針筒內部，可避免如不小心按壓到該推桿4朝該收束段21滑移時該針頭33再次穿出該注射筒2外部而造成人員被刺傷。故該注射器1具有安全、衛生作用，杜絕重覆使用的可能性。 In actual operation, when the push rod 4 slides toward the converging section 21 and the buckle portion 43 is inserted into the buckle groove 311, the buckle portion 43 is engaged with the buckle groove 311 to be injected. After the liquid is discharged for injection, the needle set 3 can be pulled into the syringe 2 through the ejector member 42. A protrusion 36 is disposed at one end of the push rod 31. When the buckle portion 43 is engaged with the buckle groove 311, the protrusion 36 of the adapter 31 can be pressed against the push. The elastic piston 41 of the rod 4 is coupled to bias the adapter 31 with the needle 33, so that the adapter 31 and the needle stay inside the syringe, so as to avoid accidentally pressing the push rod 4 toward the rod 4 When the converging section 21 slips, the needle 33 again passes out of the outside of the syringe 2 to cause a person to be stabbed. Therefore, the syringe 1 has a safety and sanitation effect, and the possibility of repeated use is eliminated.
具體而言，於本實施例中該轉接頭31可另包括相連接之一直筒段312及一朝該推桿4之方向漸擴之斜錐段313，該直筒段312係與該針基32相組接，該編碼34係設於該斜錐段313，以避免影響該直筒段312 與該收束段21之間之密合度，而導致注射液洩露。 Specifically, in the embodiment, the adapter 31 can further include a connected tubular section 312 and a tapered tapered section 313 which is gradually enlarged toward the push rod 4, and the straight section 312 is coupled to the needle base. The 32 phase is assembled, and the code 34 is disposed on the inclined cone section 313 to avoid affecting the straight section 312. The tightness with the converging section 21 causes the injection to leak.
較佳地該轉接頭31之外壁可另環設有一第一凹環314，該第一凹環314係位於該直筒段312與該斜錐段313之間，該第一凹環314套設有一密封環件35，當該轉接頭31位於該收束段21內時，該密封環件35係密封於該轉接頭31與該收束段21之間，以避免注射液自該轉接頭31與該收束段21之間的間隙洩露。該收束段21之內壁可另環設有一第二凹槽211，當該轉接頭31位於該收束段21內時，該密封環件35係卡抵於該第二凹槽211內，以防止該轉接頭31於該收束段21內任意滑動。 Preferably, the outer wall of the adapter 31 is further provided with a first concave ring 314. The first concave ring 314 is located between the straight cylinder segment 312 and the oblique cone segment 313. The first concave ring 314 is sleeved. There is a sealing ring member 35. When the adapter 31 is located in the converging section 21, the sealing ring member 35 is sealed between the adapter 31 and the converging section 21 to prevent the injection solution from rotating. The gap between the joint 31 and the converging section 21 leaks. The inner wall of the converging section 21 can be further provided with a second recess 211. When the adapter 31 is located in the converging section 21, the sealing ring member 35 is engaged with the second recess 211. In order to prevent the adapter 31 from sliding freely within the converging section 21.
詳細的說，該編碼34係為數字編號、英文及符號其中之一，其中各模具具有各自之編碼，於本實施例中該編碼34係為數字編號，由於該編碼34設於該轉接頭31，使用者可方便經由該注射筒2外看到該編碼34，且當該注射器1注射完畢後，通常會將部分該推桿4折斷丟棄，而僅留下該彈性活塞41、該推頂件42及該轉接頭31於該注射筒2內，如當該注射器1係為不良品時(如發生漏液或是堵塞)，由於各模具具有各自之編碼，即可依照該轉接頭31之該編碼34而快速追蹤得知該轉接頭31係由哪一個模具所製造出，以將此模具進行維修或淘汰，避免再重複製造出不良品。 In detail, the code 34 is one of a numerical number, an English and a symbol, wherein each of the molds has a respective code. In the embodiment, the code 34 is a digital number, since the code 34 is provided in the adapter. 31, the user can conveniently see the code 34 through the outside of the syringe 2, and when the syringe 1 is finished, a part of the push rod 4 is usually broken and discarded, leaving only the elastic piston 41, the push top The piece 42 and the adapter 31 are in the syringe 2, such as when the syringe 1 is defective (such as liquid leakage or clogging), since each mold has its own code, the adapter can be used according to the adapter The code 34 of 31 quickly tracks which mold is manufactured by the mold 31 to repair or eliminate the mold, thereby avoiding repeated manufacture of defective products.
另外，一般習知注射器於注射完後注射筒內難免仍會殘留有部分注射液，於本實施例中該彈性活塞41之外周朝該轉接頭31之方向延伸可另環設有一凸垣411，當該推桿4朝該收束段21滑移且該卡扣部43***該卡扣槽311中時，該凸垣411係抵頂於該容室22面對於該彈性活塞41之內壁而朝內彎折，其中該彈性活塞41之中心朝該轉接頭31之方向設有一凸部412，該凸垣411之延伸長度係不小於該凸部412之頂部，該凸垣411朝 內彎折可將部分殘存於該注射筒2內之注射液擠壓排出。 In addition, it is inevitable that a portion of the injection solution will remain in the syringe after the injection. In the present embodiment, the outer circumference of the elastic piston 41 extends in the direction of the adapter 31, and a protrusion 411 is additionally provided. When the push rod 4 slides toward the converging section 21 and the buckle portion 43 is inserted into the snap groove 311, the tenon 411 abuts against the inner surface of the elastic chamber 41 facing the chamber 22 And bending inwardly, wherein a center of the elastic piston 41 is disposed in a direction of the adapter 31, and a protrusion 412 is formed. The protrusion 411 has an extension length not less than a top of the protrusion 412, and the protrusion 411 faces toward the top of the protrusion 412. The inner bending can squeeze out part of the injection liquid remaining in the syringe 2.
綜上，本創作之注射器，當該轉接頭係為不良品時(如發生漏液或是堵塞)，由於各模具具有各自之編碼，即可依照該轉接頭之該編碼而快速得知該轉接頭係由哪一個模具所製造出，以將此模具進行維修或淘汰，避免再重複製造出不良品。 In summary, in the syringe of the present invention, when the adapter is a defective product (such as liquid leakage or clogging), since each mold has its own code, it can be quickly learned according to the code of the adapter. Which adapter is manufactured by which the mold is repaired or eliminated to avoid repeated manufacture of defective products.
並且，當該推桿朝該收束段滑移且該卡扣部***該卡扣槽中時，該凸垣係抵頂於該容室面對於該彈性活塞之內壁而朝內彎折，該凸垣朝內彎折可將部分殘存於該注射筒內之注射液擠壓排出。 And, when the push rod slides toward the converging section and the snap portion is inserted into the snap groove, the tenon is bent inward against the inner surface of the elastic piston against the chamber surface, The tenon is bent inward to squeeze out part of the injection liquid remaining in the syringe.
