Description

Technical Field

[0001] The utility model relates to a drainage and fixation device, in particular to a medical surgical wound drainage and fixation device. Background Art

[0002] Medical surgery refers to the medical field involving surgical operations and related treatment methods. It mainly includes the diagnosis, treatment, and management of various diseases and health problems that require surgical intervention. The main purpose of medical surgical wound drainage is to promote wound healing and reduce the risk of infection. Through drainage, secretions, blood, and other fluids in the wound can be effectively removed, creating a clean environment for the wound, which helps reduce the risk of infection and promote healing.

[0003] When draining wound effusion, a sealed drainage device is generally used to create a negative pressure environment inside the drainage tank through a vacuum pump or a negative pressure source, so that the drainage tube can suck the effusion from the wound. However, when the effusion at the wound is about to be completely drained and there is not much remaining effusion at the wound, if the drainage continues at the original speed, the following problems may occur:

[0004] Over-drainage: When there is very little effusion at the wound, if a relatively high negative pressure is still maintained, it may cause the wound tissue to be sucked into the drainage tube, thus damaging the wound;

[0005] Increased risk of infection: The damage to the wound tissue will increase the chance of infection because it may break the natural barrier of the wound, making it easier for bacteria to invade;

[0006] Increased pain and discomfort: The damage to the wound tissue may cause pain and discomfort to the patient, affecting the wound healing process.

[0007] Therefore, there is a particular need for a medical surgical wound drainage and fixation device to solve the above problems. Summary of the Utility Model

The rear side of the upper part of the drainage tank 1 is connected with the one-way exhaust pipe 2 by bonding for externally connecting a vacuum pump. The top of the drainage tank 1 is connected with the connecting pipe 3 by bolts. The front end of the connecting pipe 3 is tightly inserted with the L-shaped one-way tube 101 and the top of the drainage tank 1. The inside of the front end of the connecting pipe 3 is connected with the one-way valve 4 by bolts. The front corner of the L-shaped one-way tube 101 is connected with the support ring 103 by bonding. The drainage cover 6 is placed on the support ring 103. A hose 5 is tightly inserted between the upper part and the front side of the one-way valve 4, a one-way solenoid valve 104 is connected to the inside of the front end of the L-shaped one-way tube 101 by bolts, and the one-way solenoid valve 104 is located at the lower rear of the one-way valve 4, and a plurality of drainage tubes 61 arranged radially are connected to the inner wall of the drainage hood 6, and the upper end of the drainage tube 61 is located between the uppermost part of the drainage hood 6 and one end of the hose 5, so that the accumulated fluid inside the drainage tube 61 can flow into the hose 5, and the drainage tube 61 is provided with a plurality of liquid inlets for attracting the accumulated fluid, the drainage tank 1, the L-shaped one-way tube 101, the connecting tube 3, the hose 5, the drainage hood 6 and the drainage tube 61 are made of transparent materials, for example: polyvinyl chloride, and the edge of the outer wall of the drainage hood 6 is connected to silicone patches 62 distributed on the left and right, and also includes a volume control mechanism, and a volume control mechanism is arranged inside the connecting tube 3.

[0025] See also Figures 2 - 4 As shown, the control mechanism includes a cross rod 7, a piston 8, a clamping rod 10, a scale 12 and a spring 13. The cross rod 7 is slidably connected inside the connecting tube 3. The front end of the cross rod 7 is connected to the piston 8 by bonding, and the edge of the piston 8 is in contact with the inner wall of the connecting tube 3. The scale 12 is printed on the cross rod 7. A plurality of clamping grooves 9 distributed in a straight line are provided on the upper and lower sides of the cross rod 7. The clamping rod 10 distributed up and down is slidably connected inside the rear end of the connecting tube 3. The clamping rod 10 is clamped with the corresponding clamping groove 9, so that the cross rod 7 is fixed inside the connecting tube 3, and the clamping surface of the clamping groove 9 and the clamping rod 10 is a semicircular surface, so that when the cross rod 7 is pulled, the clamping rod 10 can be separated from the clamping groove 9, and a spring 13 for auxiliary reset is connected between the clamping rod 10 and the connecting tube 3.

[0026] See also Figures 1 - 2 As shown, it also includes a limit block 102. The front end of the connecting pipe 3 is connected to the limit block 102 by bonding. The limit block 102 is located behind the one-way valve 4 and in front of the piston 8 to contact it, limiting the piston 8 to prevent the piston 8 from moving forward under the negative pressure inside the drainage tank 1.

[0027] See also Figure 4As shown in the figure, it further includes a sealing ring 14. The outside of the rear end of the connecting pipe 3 is connected with the sealing ring 14, and the sealing ring 14 contacts the right end of the cross rod 7 to prevent external air from entering the inside of the drainage tank 1 through the gap between the rear end of the connecting pipe 3 and the cross rod 7 when exhausting the original air inside the drainage tank 1.

[0028] When it is necessary to drain the wound effusion of a patient, first, the medical staff guides the patient to maintain a correct posture. Then, the drainage tank 1 is placed on a plane, the vacuum pump is connected to the one-way exhaust pipe 2, the vacuum pump is turned on, and the original air in the drainage tank 1 is sucked away from the one-way exhaust pipe 2 to create a negative pressure environment. When all the original air inside the drainage tank 1 is sucked away, the vacuum pump is turned off and disconnected from the one-way exhaust pipe 2. Then, the drainage cover 6 is taken off from the support ring 103 and covered on the patient's wound, ensuring that the silicone pad closely fits the skin around the patient's wound to fix the drainage cover 6. Then, control the one-way solenoid valve 104 to open the L-shaped one-way pipe 101 and wait for the wound effusion to drain from the drainage pipe 61 into the drainage tank 1. The drainage process is as follows: under the negative pressure in the drainage tank 1, the drainage pipe 61 attracts the effusion at the wound, causing the effusion to flow into the drainage pipe 61, the hose 5, the one-way valve 4, and the connecting pipe 3 in sequence. The piston 8 blocks the incoming effusion inside the front end of the connecting pipe 3, causing the effusion to flow into the L-shaped one-way pipe 101 from the one-way solenoid valve 104 and finally into the drainage tank 1. When most of the wound effusion has been drained and only a small amount of effusion remains, immediately control the one-way solenoid valve 104 to close the L-shaped one-way pipe 101, then pull the cross rod 7 to the right, driving the piston 8 block to move to the right, thereby creating a negative pressure inside the connecting pipe 3 to continue draining the remaining effusion of the wound into the connecting pipe 3. During the process of pulling the cross rod 7, the cross rod 7 intermittently squeezes the plurality of latch rods 10 to move inward and disengage from the grooves, and the spring 13 is compressed accordingly. When continuing to drain, precisely pull the cross rod 7 through the scale 12 to adjust the position of the piston 8 to control the drainage speed and amount. After the remaining effusion has been drained, stop pulling the cross rod 7, and the spring 13 returns to its original state, prompting the latch rod 10 to move outward and engage with the corresponding card slot 9 to fix the cross rod 7. Again, control the one-way solenoid valve 104 to open the L-shaped one-way pipe 101 and wait for the remaining effusion in the connecting pipe 3 to flow into the drainage tank 1. Again, control the one-way solenoid valve 104 to close the L-shaped one-way pipe 101, take the drainage cover 6 off the patient's wound, put it back on the support ring 103, and finally disassemble the device for cleaning and disinfection.

[0029] It should be noted that the liquid inlet of the drainage pipe 61 of the original drainage cover 6 of the device is relatively small, which is suitable for draining a small amount of or well-flowing wound effusion. When facing a large amount of or poorly flowing wound effusion, a drainage cover 6 with a larger liquid inlet of the drainage pipe 61 can be selected to adapt to a larger effusion volume and improve the drainage efficiency.

[0030] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those of ordinary skill in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
