New description: [New technical field] C0001] This creation is about a connector, especially a needleless connector. [Prior Art] [0002] Traditionally, a syringe is used to inject a liquid medicine in a syringe into a catheter or a drip bottle so that the liquid can flow into the patient through the catheter or the infusion tube of the drip bottle. in vivo. [0006] [0006] [0007] However, the conventional syringe is provided with a needle which has to be discarded after being used for a period of time to avoid problems such as bacterial or bacterial infection, thereby causing waste of the needle. $ 宾宾发_'The same style of needle-free connection H' to eliminate the need for the needle to be discarded and transferred, eliminating the need for needle production and cost reduction, quite a combination of the other side of the market, the exchange of needle-free connection In the device, some structures are complicated and the price is expensive, but the airtight leak prevention effect is not good, so there is indeed room for improvement. Therefore, 'how to be lacking, J: Ten-day β solves the call for the present, which is the goal of the founder's improvement. [New content] [0005] One of the purposes of this creation is to provide a needle-free connector with a structure that is both airtight and simple, and has a low cost and low airtight leak-proof effect. For the above purpose, the present invention provides a needle-free connection for connecting a syringe-catheter, the needle-free connector package, a seat body comprising a partition plate and a periphery of the partition plate. a surface of a plate, a surface of which is formed with a first official member, and the other surface of the partition form No. A0101, page 3/16, M407761 has a second connection with the first tube and a second tube [0008] a resilient valve disposed on the seat body, the elastic valve including a valve portion, and a flexible member connected to the valve portion and sleeved on the first tubular member, the valve portion corresponding thereto a slit is formed above the nozzle of the pipe; and [0009] a hollow sleeve is disposed outside the elastic valve and is assembled with the seat, the hollow sleeve has an opening for inserting the syringe And a cavity communicating with the opening; [0010] wherein when the syringe is inserted into the cavity When the elastic valve is squeezed and squeezed, the flexible tube is flexibly deformed in the cavity and the valve portion abuts against the upper edge of the first tubular member to enlarge the slit and the _$'* tube The cargo moxibustion, the nozzles communicate, the liquid in the syringe flows through the _1% of the 4th tube and enters the conduit. " [0011] Compared with the prior art, the present invention has the following effects: [0012] According to the present creation, since the needle-free connector has only three components of a seat body, an elastic valve, and a hollow sleeve, the knot is : It is Ludan, the cost is reduced; and • . < Moreover, all three components can be molded 'formed and easy to assemble, thus greatly shortening the manufacturing and assembly man-hours. [0013] According to the present invention, since the outer contour of the tapered section and the abutting section of the elastic valve is equal to the inner wall contour of the hollow sleeve, when the syringe is inserted into the opening of the hollow sleeve and the elastic valve is squeezed, the tapered section The abutment section still produces a good sealing and abutting effect with the inner wall of the hollow sleeve, so the airtight leakproof effect of the present case is quite excellent. [Embodiment] Form No. A0101 Page 4 of 16 M407761 [0014] The detailed description and technical contents of the present invention will be described below with reference to the drawings, but the drawings are for illustrative purposes only and are not intended to be limiting. This creation. [0015] Please refer to the first to fifth figures. The present invention provides a needle-free connector 1 for connecting a syringe 1 and a catheter 200. The needle-free connection state 1 includes: a body 10 ' - elastic valve 20, and a hollow sleeve. The rigid seat body 10 is of a rigid plastic molding type, and comprises a partition plate 1 and a surrounding plate 12 connecting the periphery of the partition plate 11. A surface of the partition plate π is formed with a second piece 13 which is shaped by a pi The other surface is formed with a second tubular member 相4 communicating with the first tubular member η and connecting the conduit 2〇〇; as seen from the first figure, the partition 11 is The circular shape and the circular plate are rounded. • The tubular member 13 is formed on the upper surface of the partition plate 11 and faces upward: the medicine-extension ten, and the second sound member 14 is formed on the lower surface of the partition plate 11 and extends downward. The outer diameter of the first tubular member 13 is smaller than the outer diameter of the second tubular member 14, and the outer diameter of the second tubular member 14 corresponds to the inner diameter of the conduit 200, so that the conduit 2〇〇 can be tightly placed At the nozzle of the second pipe member 14. [0017] The elastic valve 20 is made of a soft plastic or rubber material, and is disposed on the base 10. The elastic valve 20 includes a valve portion 21 and a valve body 21 connected to the first official member 13 The flexible member 22, as shown in the first figure, has a substantially cylindrical shape and a slit 211 is formed above the nozzle 丨 31 corresponding to the first tubular member 13; the outer surface of the flexible member 22 is formed with a tapered shape The segment 221 is connected to the abutting portion 222 of the tapered portion 221, a flexing portion 223 connecting the abutting portion 222, and a supporting portion 224 connecting the flexing portion 223. [0018] The hollow sleeve 30 is molded of a hard plastic material, and is sleeved outside the valve 20 of the flexible form No. A0101, page 5 of the M407761, and is assembled with the seat body 10, the hollow sleeve 3〇 has an opening 31 for inserting the syringe 100 and a cavity 32 communicating with the opening 31. As is clear from the fourth figure, the contour of the upper half of the inner wall of the hollow sleeve 30 corresponds to The tapered section 2 21 of the resilient valve 20 and the contour of the abutting section 2 2 2 thereby increasing the airtightness and leakage prevention effect. Further, the abutting portion 222 of the elastic valve 2 is provided with a plurality of ring grooves 2221 which provide a space for elastic deformation when the abutting portion 222 is pushed to be elastically deformed. On the other hand, the design of the annular groove 2221 due to the outer diameter of the abutting section 222 being the largest and abutting against the hollow sleeve 3〇 helps to exist between the outer wall of the abutting section 222 and the inner wall of the hollow sleeve 30. A small amount of gas has a space for squeezing movement. [0019] The outer diameter of the towed section 223 is smaller than the hollow sleeve #, such that the flexure section II I. 'r 223 can be flexed at the edge of the hollow sleeve 30: deformation (eg, fifth-;.JΉ'* Figure shows). The contour of the support section 224 is substantially equal to the contour of the partition 11, whereby the resilient valve 20 can be stably seated on the partition 11 without causing slippage of the lower end of the elastic valve 20." The edge of the support section 224 is formed with a groove 2241. When the hollow sleeve 30 and the base 10 are assembled with each other, the bottom edge of the hollow sleeve 30 can be embedded in the groove 2241 of the support section 224 and seated. The bodies are embedded in each other. [0020] Referring to the fifth diagram, the operation principle of the present creation will be described below. When the syringe 10 is inserted into the opening 31 of the hollow sleeve 30 and the elastic valve 20 is pressed downward, the flexible tube 22 is flexibly deformed in the cavity 32 and the valve portion 21 abuts against the first tube The upper edge of 13 causes the slit 211 to expand and communicate with the nozzle 131 of the first tubular member 13. At this time, the liquid in the syringe 10 flows through the first tubular member 13 and the second tubular member 14 to enter Inside the catheter 200. [0021] Compared with the prior art, the present creation has the following effects: Form No. A0101 Page 6 / Total 16 pages M407761 [0022] According to the present creation, since the needle-free connector 1 has only the seat body 10, the elastic valve 20, And the hollow sleeve 30 has three components, so the structure is simple, the cost is low, and the three components can be molded and easily assembled, so that the manufacturing and assembly man-hours are greatly shortened.
[0023] 根據本創作，由於彈性閥20的錐狀段221與抵貼段222之 外部輪廓等於中空套筒30的内壁輪廓，所以當注射筒100 插入中空套筒30的開口 31内並擠壓彈性閥20時，錐狀段 221與抵貼段222仍舊與中空套筒30的内壁產生良好的密 封抵貼效果，故本案的氣密防漏效果相當優異。 [0024] 綜上所述，當知本創作之「為針連接:器」已具有產業 利用性、新穎性與進步性，^1^創.作之游造亦未曾見於 同類產品及公開使用，完全脅續今型專*利—申要件，爰 依專利法提出申請。 【圖式簡單說明】 [0025] 第一圖係本創作之分解立體[0023] According to the present creation, since the outer contour of the tapered section 221 and the abutment section 222 of the elastic valve 20 is equal to the inner wall contour of the hollow sleeve 30, when the syringe 100 is inserted into the opening 31 of the hollow sleeve 30 and squeezed In the case of the elastic valve 20, the tapered section 221 and the abutting section 222 still have a good sealing and abutting effect with the inner wall of the hollow sleeve 30, so the airtight leakproof effect of the present invention is quite excellent.
