Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an integrated TEE probe cleaning and disinfection machine. Background Technology

[0002] Transesophageal echocardiography (TEE) probes are medical devices that are inserted into the esophagus through the mouth to obtain images of the heart's structure and function at close range. To ensure device performance and avoid cross-infection, timely cleaning and disinfection are required after use. Manual cleaning is time-consuming, labor-intensive, and may not be thorough. Therefore, many automatic probe cleaning devices have emerged on the market. For example, Chinese utility model patent CN219850919U discloses a probe cleaner, which includes a cleaning tank, a cleaning brush, a spray head, a disinfectant storage tank, and an outlet pipe.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example: A TEE probe cleaning and disinfection integrated machine, as shown in the attached document. Figure 1 As shown, the device includes a vertical housing 1 with four casters at the bottom for easy transport. The housing 1 contains a stainless steel inner wall cleaning chamber 2 corresponding to the length of the probe guide tube. The outer side of the housing 1 has two consumable storage slots 3. The top of the housing 1 is fitted with an acrylic probe holder 4. Below the probe holder 4 is a guide tube insertion hole 5 communicating with the cleaning chamber 2; the guide tube insertion hole is larger than the diameter of the probe guide tube. (See attached diagram.) Figure 2 As shown, a rotating spray jet assembly 6 is installed in the middle of the cleaning chamber 2, and four spray jet pipes 31 are installed around the rotating spray jet assembly 6. A drain outlet 7 is opened at the bottom of the cleaning chamber 2. The drain outlet has an on / off solenoid valve (not shown in the figure) and is connected to an external floor drain through a pipeline. When soaking in disinfectant solution, the on / off solenoid valve closes the drain outlet to allow internal liquid to accumulate. When soaking, rinsing, and washing are completed, the on / off solenoid valve remains open to allow water to drain. A consumable storage tank 9 and a consumable liquid pump 10 are fixedly installed in the consumable storage tank 3. The two consumable storage tanks contain enzyme washing solution and disinfectant solution, respectively. A low liquid level sensor is installed in the consumable storage tank. The top of the consumable storage tank has a threaded cap for liquid pouring and consumable addition. The consumable liquid pump is a bidirectional liquid pump. As shown in the attached figure. Figure 3As shown, the outer casing 1 is equipped with a water supply pipe 11 that connects to both external tap water and sterile water. A flow solenoid valve 30 is mounted on the water supply pipe 11. A hot air blower 8 is also installed inside the outer casing 1. The air duct, consumable liquid pipe, and water supply pipe 11 are all connected via pipelines to the inlet of the spray jet pipe 6 and the rotary spray jet assembly 31. A controller 20 is installed on the outer casing, connecting the rotary spray jet assembly, the flow solenoid valve, the consumable liquid pump, the hot air blower, and a low-level sensor. The controller has a control panel for inputting commands. The circuit connections and signal processing for the input and information display are technical means well known and mastered by those skilled in the art, and will not be described in detail here; the rotary spray jet assembly 6 includes a vertical sleeve 12 assembled at the bottom of the cleaning chamber 2 and connected to the motor. The bottom end of the vertical sleeve is frictionally sealed to the wall of the cleaning chamber through a sealing sleeve. Spray holes 13 communicating with the inner cavity are evenly opened on the side walls of the spray jet pipe 31 and the vertical sleeve 12. A connecting pipe 14 is fixed at the top of the cleaning chamber 2. The end of the connecting pipe is rotatably connected to the vertical sleeve. The spray jet pipe and the connecting pipe are connected to the vertical sleeve. The connecting pipe 14 is fixedly connected to the water supply pipe 11, consumable liquid pipe 22, and air duct 23 via pipelines. The motor drives the vertical sleeve to rotate around the connecting pipe. After the liquid enters, it is thrown out of the spray hole by centrifugal force to achieve uniform spraying. The outer shell 1 of the machine body is equipped with a heating pipe 15 connected to the controller. The inlet end of the spray jet pipe 31 and the rotating spray jet assembly 6 is connected to an S-shaped heating pipe 16. The heating pipe 16 is connected to the air duct 23, consumable liquid pipe 22, and water supply pipe 11, which can regulate the liquid flowing into the spray nozzle. The liquid before the spray nozzles is heated to a suitable temperature for the enzyme washing solution. Simultaneously, the hot air blower provides secondary heating to maintain a constant temperature. The S-shaped design ensures reliable heating. The top of the outer casing 1 is equipped with a power supply basket 17 located on the side of the probe mounting base 4, used to hold the probe power supply and improve placement stability. The spray nozzles 6 are evenly distributed in a ring around the center of the cleaning chamber, providing sufficient spray range, and all nozzles face inwards for centralized spraying. (See attached...) Figure 4As shown, a knob 24 is interference-fitted to the side of the catheter insertion port 5. A first arc-shaped block 25 located inside the cleaning chamber 2 is fixed to the lower end of the knob 24. A second arc-shaped block 26 corresponding to the first arc-shaped block 25 is fixed to one side wall of the catheter insertion port 5. The first arc-shaped block 25 and the second arc-shaped block 26 close to form a sealing hole 27 that fits with the probe catheter. Before inserting the probe catheter, the two are kept separate, and the larger opening allows for quick insertion of the catheter. After complete placement, the knob is rotated, causing the first arc-shaped block to fit against the second arc-shaped block, thereby closing to form a sealing hole that fits with the catheter, thus fixing the catheter and sealing the cleaning chamber. The outer end of the cleaning chamber 2 is connected to and fixed to the outside. A transparent observation window 22 allows external observation of the internal cleaning process. A first check valve 28 is fitted to the end of the consumable liquid pipe 22 to prevent backflow of other liquids and reduce residual liquids in the pipe. A check valve 29 is fitted to the air duct 23 to prevent liquid from flowing back into the hot air blower, improving reliability. The bottom of the cleaning chamber 2 is equipped with a circulating liquid recovery port 32, also fitted with an opening and closing solenoid valve. The circulating liquid recovery port 32 is connected to the disinfectant consumable liquid pipe 22 via a pipe. After soaking in the disinfectant, the opening and closing solenoid valve opens, and the consumable liquid pump draws the soaking liquid back into the corresponding consumable box from the circulating liquid recovery port, achieving recycling.

[0018] Working principle: Before use, fill the two consumable boxes 9 in the consumable storage tank 3 with disinfectant and enzyme cleaning solution respectively, and connect the consumable box 9 to the consumable liquid pump 10. At the same time, connect the water supply pipe 11 in the outer shell 1 to the external tap water and sterile water dual-line water supply. Then, place the base of the probe 21 to be cleaned on the probe hanging seat 4 on the top of the outer shell 1, so that the probe 21 conduit passes through the conduit insertion hole 5 below the probe hanging seat 4 and extends into the cleaning chamber 2. Turn the knob to complete the fixation and sealing through the sealing hole. During operation, the flow solenoid valve 30 on the water supply pipe 11 and the consumable liquid pump 10 are controlled by the controller 20 to deliver water and consumable liquid separately or in combination. The liquid first flows through the S-shaped heating pipe 16. If it is the enzyme washing stage, the heating pipe 15 inside the outer casing 1 is activated to heat the liquid in the pipe to the appropriate temperature for the enzyme washing solution. Then the liquid enters the connecting pipe 14 and flows into the spray jet pipe 31 and the vertical sleeve pipe 12. The motor drives the vertical sleeve pipe 12 to rotate, and the liquid is thrown out from the spray holes 13 evenly distributed on the side wall of the vertical sleeve pipe 12 under centrifugal force. This, together with the four dispersed spray jet pipes 6, achieves the detection of the enzyme liquid. The probe tube is uniformly rinsed or immersed in a spray solution. The soaking solution (disinfectant) and rinsing solution are discharged from the circulating liquid recovery port 32 and the drain port 7 at the bottom of the cleaning chamber 2, respectively. After drainage, the hot air blower 8 is started, and the hot air quickly dries the probe tube. The complete cleaning process is carried out through the above-mentioned working method, namely water intake, initial water rinsing, enzyme washing, water rinsing, drainage, hot air drying, disinfectant spray immersion, discharge and recovery of disinfectant, water rinsing, drainage and hot air drying. The internal condition can be observed through the transparent observation window 19 outside the cleaning chamber 2 throughout the cleaning process.
