本發明係使用於醫療器材及醫療衛材領域的尿管連接裝置，特別是指一種方便使用、且可減少感染風險的尿管連接泵裝置。The present invention relates to a urinary catheter connection device for use in the fields of medical equipment and medical hygiene products, and in particular to a urinary catheter connection pump device that is easy to use and can reduce the risk of infection.
在醫學臨床上，膀胱化療灌藥、收取尿液培養檢體及膀胱沖洗需將尿管與尿袋分離，此動作極易增加感染風險。尤其於執行膀胱化療灌藥時需將尿管與尿袋分離，再使用灌食空針將化療藥物由尿管灌入膀胱，過程中須保持無菌原則，而後使用止血鉗（Kelly clamp）或橡皮筋（Rubber band）將尿管阻斷引流，避免化療藥物流出，確實阻斷引流後必須將尿管與尿袋再次接回，待一小時過後將關閉的尿管解開保持暢通，使化療藥物排出，待藥物完全排出後，再次將尿管與尿袋分離，將充滿化療藥物的尿袋丟棄，更換全新尿袋。過程不僅耗時、步驟繁瑣，更消耗時間成本，尿管與尿袋反覆分離銜接也難以維持無菌，容易導致泌尿道感染，並且有極大機率造成化療藥物外滲潑灑的風險。In clinical medicine, bladder chemotherapy, urine culture, and bladder flushing require the catheter to be separated from the urine bag, a procedure that can easily increase the risk of infection. Especially when performing bladder chemotherapy, the catheter must be separated from the urine bag, and then the chemotherapy drugs must be instilled into the bladder through the catheter using an empty feeding needle. Sterility must be maintained throughout the process. A Kelly clamp or rubber band should then be used to block the drainage of the catheter to prevent the chemotherapy drugs from leaking out. After the drainage is effectively blocked, the catheter and urine bag must be reconnected. After one hour, the closed catheter should be untied to keep it unobstructed to allow the chemotherapy drugs to be discharged. After the drugs are completely discharged, the catheter and urine bag should be separated again, and the urine bag filled with chemotherapy drugs should be discarded and replaced with a new one. The process is not only time-consuming and cumbersome, but also difficult to maintain sterility due to the repeated separation and connection of the catheter and urine bag, which can easily lead to urinary tract infections and pose a high risk of chemotherapy drug leakage and splashing.
再者，使用止血鉗將尿管夾起後，過程中需定時更換臥位，會造成患者翻身不易且讓患者身體感到不適。若使用橡皮筋綑綁反折尿管也無法牢固，易增加化療藥物外滲風險。Furthermore, clamping the catheter with a hemostat requires periodic changes of patient position, making it difficult for the patient to turn over and causing discomfort. Using a rubber band to secure the folded catheter also fails, increasing the risk of chemotherapy leakage.
藉由上述臨床觀察得到的問題，發明人團隊亟思加以改良上述習知技術的各項缺點，經不斷測試改良後，終於成功研發完成本發明之尿管連接泵裝置。Based on the problems identified in the above clinical observations, the inventor team was eager to improve the various shortcomings of the above-mentioned known technologies.

It is made of medical-grade polyethylene (PE) and is integrally molded. Medical-grade PE prevents corrosion from chemotherapy drugs and avoids the formation of plasticizers, making it suitable for a wide range of chemotherapy drugs. However, the material and manufacturing method are not limited to this. The pump connection catheter 11 includes a urinary catheter connection tube 111, a drug infusion tube 112, and a urine bag connection tube 113. Each tube forms a connected space within which medication or urine can flow. The openings of each tube are a urinary catheter connection port 114, a drug infusion port 115, and a urine bag connection port 116.
尿管連接管111設於連接泵導管11的其中一側，係將一尿管17固定於尿管連接端114，使尿管連接管111與尿管17的管內連通，膀胱中的尿液可以經由尿管17流向尿管連接管111；藥物灌注管112設於連接泵導管11的另一側，需注射藥物時，由藥物灌注端115輸入藥物，並通過藥物灌注管112、尿管連接管111、尿管17輸送至膀胱，且藥物灌注端115的開口可以符合任意尺寸的空針；尿袋連接管113設於連接泵導管11的另一側且位於藥物灌注管112的鄰側，係將一尿袋18固定於尿袋連接端116，使尿袋連接管113與尿袋18的管內連通，流進尿管連接管111內的尿液，能順利流進尿袋18內，且尿袋連接端116的開口可以符合任意尺寸的尿袋18。The urinary catheter connecting tube 111 is provided on one side of the connecting pump catheter 11. A urinary catheter 17 is fixed to the urinary catheter connecting end 114, so that the urinary catheter connecting tube 111 and the urinary catheter 17 are connected. Urine in the bladder can flow into the urinary catheter connecting tube 111 through the urinary catheter 17. The drug infusion tube 112 is provided on the other side of the connecting pump catheter 11. When drugs are to be injected, drugs are injected from the drug infusion end 115 and delivered through the drug infusion tube 112, the urinary catheter connecting tube 111, and the urinary catheter 17. The drug infusion end 115 is provided with an opening that can accommodate an empty needle of any size. The urine bag connection tube 113 is provided on the other side of the pump catheter 11 and adjacent to the drug infusion tube 112. A urine bag 18 is fixed to the urine bag connection end 116, so that the urine bag connection tube 113 is connected to the tube of the urine bag 18. Urine flowing into the urine catheter connection tube 111 can flow smoothly into the urine bag 18. The opening of the urine bag connection end 116 can accommodate urine bags 18 of any size.
另請參閱圖2及圖3，為本發明之尿管連接泵裝置的一實施例與另一實施例剖面示意圖。開關閥12係設於尿袋連接管113的管體內靠近尿袋連接端116，開關閥12在於切換尿袋連接管113與尿管連接管111的連通。例如，正常使用時，開關閥12打開，尿袋連接管113與尿管連接管111之間為連通，尿液可正常流入尿袋18；進行藥物注射時，將開關閥12關閉，並阻斷尿袋連接管113與尿管連接管111連通，藥物僅可從通過藥物灌注管112、尿管連接管111與尿管17輸送至膀胱。Please also refer to Figures 2 and 3, which are schematic cross-sectional views of one embodiment and another embodiment of the urinary catheter connection pump device of the present invention. The switch valve 12 is disposed within the tube body of the urine bag connection tube 113 near the urine bag connection end 116. The switch valve 12 switches the connection between the urine bag connection tube 113 and the urinary catheter connection tube 111. For example, during normal use, the switch valve 12 is opened, and the urine bag connection tube 113 and the urinary catheter connection tube 111 are connected, allowing urine to flow normally into the urine bag 18. When administering medication, the switch valve 12 is closed, blocking the connection between the urine bag connection tube 113 and the urinary catheter connection tube 111. Medication can only be delivered to the bladder through the medication infusion tube 112, the urinary catheter connection tube 111, and the urinary catheter 17.
單向瓣膜13係為一單向閥，單向瓣膜13係設於尿袋連接管113的管體內遠離尿袋連接端116，單向瓣膜13僅提供尿液從尿管連接管111流通至尿袋連接管113，並防止尿液流至尿管連接管111，避免泌尿道逆行性感染。因設有單向瓣膜13，此時不論尿袋18與使用者的相對位置，尿液皆不會從尿袋連接管113回流至尿管連接管111及尿管17，避免泌尿道逆行性感染。The one-way valve 13 is a one-way valve. It is located within the urine bag connection tube 113, away from the urine bag connection end 116. This valve only allows urine to flow from the urinary catheter connection tube 111 to the urine bag connection tube 113 and prevents urine from flowing into the urinary catheter connection tube 111, thus preventing retrograde urinary tract infection. Because of the one-way valve 13, regardless of the relative position of the urine bag 18 and the user, urine cannot flow back from the urine bag connection tube 113 into the urinary catheter connection tube 111 and the urinary catheter 17, thus preventing retrograde urinary tract infection.

In one embodiment, the present invention further includes a screw latch 16 disposed on the urine bag connection tube 113, freely movable between the urine bag connection end 116 and the on-off valve 12. When a urine bag 18 is coupled to the urine bag connection end 116, the screw latch 16 connects the urine bag 18 to the urinary catheter connection end 114. After urine flows out of the bladder, it flows into the urine bag 18 through the urinary catheter connection tube 111. The screw latch 16 is manufactured using 3D printing technology, but the manufacturing method is not limited to this.
尿管連接管111、藥物灌注管112或尿袋連接管113更包括一防脫落裝置117，設於管體外周緣靠近各開口，例如具有螺紋型態及錐度的餌扣鎖（lure lock），但製造方法不受此限。防脫落裝置藉由複數節凸起物增加接合的摩擦力，進而防止脫落。The urinary catheter connection tube 111, medication infusion tube 112, or urine bag connection tube 113 further includes an anti-dropout device 117 located on the outer periphery of the tube near each opening. Such a device may be, for example, a lure lock with a threaded and tapered shape, but the manufacturing method is not limited thereto. The anti-dropout device utilizes multiple raised protrusions to increase friction during engagement, thereby preventing dropout.
本發明之尿管連接泵裝置10可連接於單腔導尿管、雙腔導尿管或三腔導尿管任意一種導尿管。The urinary catheter connection pump device 10 of the present invention can be connected to any of single-lumen urinary catheters, double-lumen urinary catheters, and triple-lumen urinary catheters.
