DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example 1
[0022] See also Figure 1-Figure 5 The figure shows a wound drainage liquid negative pressure sterile collection cup, which includes a cup body 1, a suction tube 3, a blocking component and a suction component. A connecting tube 2 is fixedly provided at one end of the cup body 1, and a sleeve 18 is connected at one end of the suction tube 3. The sleeve 18 is sleeved on the outside of the connecting tube 2; the blocking component is installed inside the sleeve 18 to block one end of the connecting tube 2 and seal the connecting tube 2; the suction component is installed inside the cup body 1 to generate negative pressure inside the cup body 1 so that the liquid at the wound is sucked into the cup body 1.
[0023] See also Figure 2-Figure 5 The plugging assembly shown in the figure includes a truncated cone block 4 fixedly arranged at one end of the suction pipe 3, the truncated cone block 4 is hollow, and the truncated cone block 4 is located inside the sleeve 18, a plurality of overflow holes 5 are opened at equal distances on the side wall of the truncated cone block 4, and a plugging block 6 is fixedly arranged at one end of the truncated cone block 4 away from the suction pipe 3;
[0024] See also Figure 2-Figure 5 The blocking component shown in the figure also includes a funnel cover 7 fixed inside one end of the connecting pipe 2 and matching the truncated cone block 4. A hole 8 matching the blocking block 6 is opened at one end of the funnel cover 7.
[0025] See also Figure 2-Figure 4The suction assembly shown in the figure includes a piston 9 arranged inside the cup body 1, and a pull rod 10 is fixedly provided at one end of the piston 9 away from the connecting pipe 2. One end of the pull rod 10 penetrates the cup body 1 and extends outward to be fixedly connected to the handle 11.
[0026] When using the wound drainage liquid negative pressure sterile collection cup: first, twist the sleeve 18 to move the sleeve 18 on the surface of the connecting tube 2, move the sleeve 18 away from one end of the cup body 1, and move the truncated cone block 4 inside the sleeve 18 out of the funnel cover 7. When the truncated cone block 4 moves out, it can drive the blocking block 6 to be pulled out from the hole 8, so as to achieve the connection between the cup body 1 and the connecting tube 2 and the sleeve 18. After the blocking block 6 is separated from the hole 8, stop twisting the sleeve 18, and then place one end of the suction tube 3 on the patient's wound, and then pull the handle 1. 1, pull the handle 11 to drive the pull rod 10 to slide inside the cup body 1, and when the pull rod 10 is pulled, it will drive the piston 9 to move toward the end away from the connecting pipe 2. At this time, the internal space of the cup body 1 increases to create a negative pressure, so that the drainage fluid at the patient's wound enters through the suction tube 3, and then enters the middle of the truncated cone block 4, and flows out from the overflow hole 5 on the side of the truncated cone block 4 to the funnel cover 7, and then enters the connecting pipe 2 through the hole 8 at one end of the funnel cover 7, and finally enters the cup body 1 through the connecting pipe 2, so as to collect the drainage fluid at the patient's wound.
[0027] After the collection of the drainage fluid at the wound is completed, the staff then twists the sleeve 18 in the opposite direction to move the sleeve 18 toward the side close to the cup body 1. At this time, the sleeve 18 drives the truncated cone block 4 to move toward the inside of the funnel cover 7, driving the blocking block 6 to block the hole 8. At this time, the hole 8 at the funnel cover 7 can be blocked, thereby protecting the drainage fluid collected inside the cup body 1, avoiding the outflow of the drainage fluid when the cup body 1 is placed at an angle, and increasing the safety of drainage fluid collection and placement; at the same time, after the blocking block 6 blocks the hole, it is avoided that external bacteria enter and pollute the drainage fluid inside the cup body 1, thereby increasing the safety of drainage fluid storage inside the cup body 1, and avoiding the traditional method of using a suction tool to suck the drainage fluid at the wound into the suction tool, and then pushing the drainage fluid collected in the suction tool into the collection cup, so that the suction tool is used as a tool for collection, which is easy to cause drainage fluid contamination and affects the safety of drainage fluid collection.
[0028] The initial state of the cup body 1 is that the blocking component blocks the connecting pipe 2 . The cup body 1 that has been aseptically treated is not contaminated by external bacteria, thereby improving the safety of the placement of the cup body 1 .
[0029] When the drainage fluid inside the cup body 1 needs to be sent to the machine for inspection in the laboratory, the sleeve 18 needs to be removed from the connecting tube 2 to open the hole 8, and then the staff can use the sampling needle to insert it into the cup body 1 to sample the drainage fluid. This device is convenient for collecting and storing the drainage fluid from the wound, while avoiding contamination during the collection of the drainage fluid, and is convenient for opening and sampling during inspection, which can effectively improve the accuracy of drainage fluid detection and improve the convenience of use for staff.
