Description

Technical Field

[0001] The present invention relates to the technical field of medical devices for draining blood stasis, and in particular to a device for draining blood stasis prevention used in neurosurgery. Background Art

[0002] The blood drainage device is a medical device used to drain blood and water seeping from surgical wounds. Its main structure includes a drainage tube, a waste liquid bottle for collecting waste liquid, and an external negative pressure device. Among all the parts of the drainage device, the drainage tube is the most prone to blockage. The main reasons for blockage of the drainage tube are: blockage caused by blood coagulation and blockage by blood and flesh tissue.

[0003] For example, a neurosurgery anti-hemorrhage drainage device with patent publication number CN108815594A raises similar issues as above. Therefore, the present application provides a neurosurgery anti-hemorrhage drainage device to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drainage device for preventing blood accumulation for neurosurgery to solve the problem of blockage of existing drainage tubes.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A drainage device for preventing blood accumulation for neurosurgery includes a waste liquid tank and a drainage tube connected to the waste liquid tank. The drainage tube is configured as a transparent thick tube and a thin tube portion, wherein the thin tube portion is located between the transparent thick tubes. One end of the transparent thick tube is configured as a liquid inlet that contacts the accumulated blood, and a clearing module is provided on one side of the thin tube portion located on the liquid inlet.

[0007] Optionally, the thin tube portion includes a conversion cylinder connected to the transparent thick tube and a plurality of transparent thin tubes, wherein the plurality of transparent thin tubes are arranged in a circular array with the axis of the conversion cylinder as the center and the two ends are respectively connected to the conversion cylinder.

[0008] Optionally, the transparent thick tube and the transparent thin tube are both made of PVC material.

[0009] Optionally, the clearing module is arranged on a side close to the liquid inlet, and includes a transparent channel integrally constructed with the conversion cylinder. A plurality of equidistantly arranged pistons are arranged in the transparent channel, and the plurality of pistons are fixedly connected by plastic rods to form a sealed space between two adjacent pistons.

[0010] Optionally, it further includes a constant temperature electric heating rod disposed between the two conversion cylinders, and the constant temperature is 37° C., and both ends of the constant temperature electric heating rod are respectively fixed on the conversion cylinder.

[0011] Optionally, two covers are further included, which are wrapped around the outside of the multiple transparent tubes and fixedly installed on the conversion cylinder. One of the covers is configured with a wire hole for the wire of the constant temperature electric heating rod to pass through.

[0012] Optionally, the waste liquid tank includes a waste liquid collection chamber and a conversion chamber for connecting to a medical negative pressure machine. A suction connection port and a conversion port 1 are provided at the top of the waste liquid tank corresponding to the waste liquid collection chamber; a negative pressure connection port and a conversion port 2 are provided corresponding to the conversion chamber. The bottom port of the conversion port 2 is fixed with a liquid seal tube extending into the bottom of the conversion chamber. The bottom of the conversion chamber is filled with a solution that submerges the bottom port of the liquid seal tube. A rubber tube is connected between the conversion port 1 and the conversion port 2.

[0013] Optionally, a secondary suction mechanism is also included, which is used to extract blood and flesh tissue in the transparent thick tube and includes a hard tube body fixedly connected to the suction connection port and a ball valve arranged on the hard tube body. The hard tube body is located above the ball valve and is obliquely fixedly connected to a suction tube, and an injection rod is slidably arranged inside the suction tube.

[0014] Optionally, a hanging hook is fixed to the outer wall of the chamber.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, the thickness conversion is achieved by setting a transparent thick tube part to a thin tube part. In practice, when blood and flesh tissue reaches the thin tube part, it will block part of the thin tube, but it will not cause all the thin tubes to be blocked. Therefore, the drainage tube can still work at this time. The design here converts the original thick tube into a thin tube with multiple channels, thereby avoiding the problem of the drainage tube being completely blocked and causing complete inability to drain to a certain extent.

[0017] By setting the piston to move in the transparent channel, the connection between the conversion cylinder and the capillary tube can be scraped, and the sealed spaces between multiple pistons are relatively independent. When medical staff see from the transparent channel that the capillary tube is in a blocked state, they can push the piston to move, then the adjacent sealed space will move, and the piston will push the blocked flesh and tissue outward to achieve the purpose of clearing the blockage.

[0018] By setting a constant temperature electric heating rod, the thin tubes surrounding it can be heated to 37°C, avoiding blood viscosity caused by low temperature and accelerating coagulation. BRIEF DESCRIPTION OF THE DRAWINGS

The device may be oriented in other ways, and the spatially relative descriptors used herein should be similarly interpreted accordingly.

[0035] like Figures 1 to 7As shown, an embodiment of the present invention provides a drainage device for preventing blood accumulation for neurosurgery, comprising a waste liquid tank 1 and a drainage tube 2 connected to the waste liquid tank 1. It should be noted that the drainage device in practice should also include a medical negative pressure machine, which provides negative pressure for the drainage tube 2 to suck out the accumulated fluid. The key part of this application is that the drainage tube 2 is provided with a transparent thick tube 21 and a thin tube portion 22, wherein the thin tube portion 22 is located between the transparent thick tube 21, one end of the transparent thick tube 21 is provided with a liquid inlet 23 in contact with the accumulated blood, and the thin tube portion 22 is provided with a clearing module 24 on one side of the liquid inlet 23, as shown in FIG. Figure 4 As shown in the figure, the thin tube part 22 includes a conversion cylinder 221 connected to the transparent thick tube 21 and multiple transparent thin tubes 222, and the multiple transparent thin tubes 222 are arranged in a circular array with the axis of the conversion cylinder 221 as the center and the two ends are respectively connected to the conversion cylinder 221. This design enables the drainage tube 2 to achieve a thick-thin conversion from the transparent thick tube 21 part to the thin tube part 22. In practice, when blood and flesh tissue reaches the thin tube part 22, it will block part of the thin tube, but it will not cause all the thin tubes to be blocked. Therefore, the drainage tube 2 can still work at this time. The design here converts the original thick tube into a thin tube with multiple channels, thereby avoiding the problem of the drainage tube 2 being completely blocked and causing complete inability to drain to a certain extent. It should be noted that the transparent thick tube 21 and the transparent thin tube 222 here are both made of PVC material.

[0036] like Figures 5 to 7 As shown, in another embodiment of the present application, in order to further ensure the reliable operation of the drainage tube 2, the clearing module 24 is arranged on the side close to the liquid inlet 23, which includes a transparent channel 241 integrally constructed with the conversion cylinder 221, and a plurality of pistons 242 arranged at equal distances are arranged in the transparent channel 241. The plurality of pistons 242 are fixedly connected by plastic rods 243 to form a sealed space 244 between two adjacent pistons 242. Figure 7 As can be seen from the figure, when the piston 242 moves in the transparent channel 241, it can scrape the internal space of the conversion cylinder 221 and the connection with the thin tube, and the sealed space 244 between multiple pistons 242 is relatively independent. When medical staff see from the transparent channel 241 that the internal space of the conversion cylinder and the connection between the conversion cylinder and the thin tube are in a blocked state, they can push the piston 242 to move, then the adjacent sealed space 244 will move, and the piston 242 will push the blocked flesh and blood tissue outward to achieve the purpose of clearing the blockage. The technical purpose here is to achieve the purpose of clearing the blockage while drainage is in progress.

[0037] like Figure 6 As shown, based on the above embodiment, it also includes a constant temperature electric heating rod 3 set between the two conversion cylinders 221, and the constant temperature is 37°C. The two ends of the constant temperature electric heating rod 3 are respectively fixed on the conversion cylinder 221. Figure 6 In the figure, it can be seen that the constant temperature electric heating rod 3 can heat the thin tubes surrounding it at 37°C. Studies have shown that when the blood is below 35°C, it will activate platelets, increase blood viscosity, and accelerate coagulation. Therefore, the constant temperature electric heating rod 3 can effectively avoid this defect. It should be noted that the constant temperature electric heating rod 3 is a miniature model, and in order to achieve the best constant temperature heating effect, it also includes two covers 6, which are wrapped around the outside of multiple transparent thin tubes 222 and fixedly mounted on the conversion cylinder 221 at both ends. One of the covers 6 is constructed with a wire hole 61 for the wire of the constant temperature electric heating rod 3 to pass through. The wire hole 61 is provided to facilitate the extraction of the power cord of the constant temperature electric heating rod 3.

[0038] like Figures 1 to 3 As shown, the waste liquid tank 1 includes a waste liquid collection chamber 11 and a conversion chamber 12 for connecting to a medical negative pressure machine. A suction connection port 111 and a conversion port 112 are provided at the top of the waste liquid tank 1 corresponding to the waste liquid collection chamber 11; a negative pressure connection port 121 and a conversion port 2 122 are provided corresponding to the conversion chamber 12. The bottom end of the conversion port 2 122 is fixed with a liquid sealing tube 13 extending into the bottom of the conversion chamber 12. Figure 3 The conversion port 112 here is used to connect the suction catheter port of the medical suction machine, and the suction connection port 111 is used to connect the drainage pipe. The suction connection port 111, the conversion port 112, the negative pressure connection port 121, and the conversion port 2 122 are all technical structures existing in the prior art, and the bottom of the conversion chamber 12 is filled with a solution that submerges the bottom of the liquid seal tube 13. A rubber tube 14 is connected between the conversion port 112 and the conversion port 2 122. The main purpose is that when the negative pressure suction catheter port of the medical suction machine is connected to the conversion port 2 122, the pressure in the conversion chamber 12 becomes smaller, and then the pressure in the waste liquid collection chamber 11 connected to the conversion chamber 12 through the rubber tube 14 will also become smaller. At this time, the accumulated fluid in the drainage tube 2 will enter the waste liquid collection chamber 11, and the liquid contained in the conversion chamber 12 here is generally alcohol.

[0039] like Figure 1 、 Figure 2 and Figure 4As shown, in order to avoid the transparent thick tube 21 from being unable to be processed online after being clogged, a secondary silt suction mechanism 4 is also included, which is used to extract the blood and flesh tissue in the transparent thick tube 21 and includes a hard tube body 41 fixedly connected to the suction connection port 111 and a ball valve 42 arranged on the hard tube body 41. The hard tube body 41 is located above the ball valve 42 and is fixedly connected to a suction tube 43. An injection rod 44 is slidably arranged inside the suction tube 43. First of all, it should be noted that the suction tube 43 and the injection rod 44 here form an overall effect of a syringe, which can realize the pulling and drawing effect. When the transparent thick tube 21 at the upper end of the thin tube is clogged, it is first closed. Close the ball valve 42, then pull the injection rod 44 so that the clogged flesh and blood or coagulated blood is drawn into the suction tube 43, then open the ball valve 42, bend the thick tube part with your fingers, and at this time push the injection rod 44 so that the clogged material there is pushed into the waste liquid collection chamber 11 by the airflow. When the transparent thick tube 21 at the lower end of the thin tube is blocked, first close the ball valve 42, then pull the injection rod 44, so that the clogged flesh and blood or coagulated blood is drawn into the transparent channel 241, and then push the piston 242 to clear the clogged material out of the drainage channel. In order to facilitate use, a hanging hook 5 is fixed to the outer wall of the chamber in this application.

[0040] The workflow of the technical solution provided by the present invention is as follows:

[0041] When using, first install Figure 1 、 Figure 2 After connecting all the components, start the medical negative pressure machine to aspirate the liquid. Because the transition point from the transparent thick tube 21 to the thin tube becomes narrow, blood and flesh tissue blockages will gather here. After a period of time, it is found that the drainage effect is not good. At this time, the piston 242 can be pushed to scrape off the blockage at the connection between the conversion cylinder 221 and the thin tube to ensure effective drainage.

[0042] When the transparent thick tube 21 at the upper end of the thin tube is blocked, first close the ball valve 42, then pull the injection rod 44 so that the blocked flesh or coagulated blood is drawn into the suction tube 43, then open the ball valve 42, bend the thick tube part with your fingers, and then push the injection rod 44 so that the blockage there is pushed into the waste liquid collection chamber 11 by the airflow.

[0043] When the transparent thick tube 21 at the lower end of the thin tube is blocked, first close the ball valve 42, then pull the injection rod 44 so that the blocked flesh or coagulated blood is drawn into the transparent channel 241, and then push the piston 242 to clear the blockage out of the drainage channel.

[0044] At the same time, the power supply of the constant temperature electric heating rod 3 needs to be turned on during drainage work so that the thin tube surrounding it can be heated to 37°C, thereby avoiding the blood viscosity in the drainage tube 2 being lower than 35°C, accelerating coagulation, and increasing the risk of congestion.

[0045] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
