Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a chest drainage tube after pneumonectomy. Background Art

[0002] After a complete lung resection, there will be blood, exudate and residual gas in the chest cavity; the chest drainage tube can drain these liquids and gases to prevent excessive accumulation of fluid and gas in the chest cavity, which will lead to increased pressure in the chest cavity, thereby avoiding compression of the mediastinum and displacement to the healthy side, affecting cardiopulmonary function; during the use of the chest drainage tube, medical staff usually wrap a part of the tube with gauze, and then clamp it with forceps. The purpose of wrapping with gauze is to prevent damage to the tube during the clamping process. The chest drainage tube is generally fully clamped or half clamped. , to ensure that there is a certain amount of pleural fluid in the affected side to resist the movement of the pleura into the cavity after surgery, maintain the pressure balance in the bilateral thoracic cavity, and prevent excessive swing of the mediastinum; when fully clamped, the time and number of times the drainage tube is opened can be adjusted according to the position of the trachea. If the trachea is obviously displaced to the healthy side, after excluding atelectasis, an appropriate amount of gas or shortness of breath and drainage fluid can be released as appropriate. The amount of fluid released each time should not exceed 100 ml, and the speed should be slow to avoid rapid and large-scale fluid release causing sudden displacement of the mediastinum, leading to cardiac arrest. When half-clamped, pay attention to keeping the amplitude of the water column in the drainage tube fluctuating with breathing at 4 to 6 cm.

[0003] In the prior art, chest drainage tubes are usually clamped with forceps to achieve a semi-clamped or fully-clamped state. However, the clamping method of clamping the chest drainage tube with forceps has the following problems: first, the stability of clamping the drainage tube with forceps needs to be improved; second, it is difficult to accurately clamp the tube to a fully-clamped or semi-clamped state.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this invention.

[0041] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0042] Example 1:

[0043] See also Figure 1-4 The post-pulmonary resection chest drainage tube provided in the present application includes a tube body 101 and a tube sleeve 1 fixedly connected to the tube body 101, and also includes: a first abutment rod 11, the first abutment rod 11 is slidably connected to the tube sleeve 1; a second abutment rod 12, the second abutment rod 12 is slidably connected to the tube sleeve 1, and the first abutment rod 11 and the second abutment rod 12 are arranged opposite to each other; a transmission mechanism 2, which is suitable for when the first abutment rod 11 slides relative to the tube sleeve 1, the first abutment rod 11 abuts the tube body 101 and the first abutment rod 11 drives the second abutment rod 12 to synchronously abut the tube body 101 through the transmission mechanism 2; an adjustment mechanism 3, which is suitable for, when the first abutment rod 11 and the second abutment rod 12 abut the tube body 101, to enable the abutted part of the tube body 101 to be in a semi-closed state and a fully closed state.

[0044] It should be noted that the first abutting rod 11 and the second abutting rod 12, the second abutting rod 12 are all slidably connected to the pipe sleeve 1, and the sliding connection can be achieved by means of a sleeve, a slide rail, etc.; the first abutting rod 11 and the second abutting rod 12 are arranged opposite to each other, and the tube body 101 is placed between the first abutting rod 11 and the second abutting rod 12. In the process of the first abutting rod 11 abutting and squeezing toward the tube body 101, under the action of the transmission mechanism 2, the second abutting rod 12 synchronously abuts the tube body 101, and the strokes of the first abutting rod 11 and the second abutting rod 12 are synchronized, thereby achieving precise abutment and squeezing of the tube body 101, and then changing the flow state of the tube body 101; the adjustment mechanism 3 can control the flow state of the tube body 101 by controlling the distance traveled by the first abutting rod 11 and the second abutting rod 12, such as using a motor to cooperate with a processor to drive the first abutting rod 11 and the second abutting rod 12, or using an air pump air pressure to drive the first abutting rod 11 and the second abutting rod 12, etc.

[0045] Example 2:

[0046] See also Figure 1-4The post-pulmonary resection chest drainage tube provided in the present application includes all the contents of Example 1. In addition, the transmission mechanism 2 includes: a first rack 21, the first rack 21 is fixedly connected to the first abutment rod 11; a second rack 22, the second rack 22 is fixedly connected to the second abutment rod 12; a gear 23, the gear 23 is rotatably connected to the sleeve 1, the first rack 21 and the second rack 22 are both engaged with the gear 23, and the first rack 21 and the second rack 22 are facing opposite each other.

[0047] It should be noted that when the first abutment rod 11 moves toward or away from the tube body 101, it drives the first rack 21 to move synchronously toward or away from the tube body 101. At this time, the first rack 21 drives the gear 23 to rotate through the meshing gear 23, and the rotation of the gear 23 synchronously drives the second rack 22 to move. Since the first rack 21 and the second rack 22 are arranged in opposite directions, the second rack 22 is synchronously driven to move toward or away from the tube body 101 along with the first rack 21, thereby realizing the synchronization of the second abutment rod 12 approaching or moving away from the tube body 101.

[0048] In a preferred embodiment, a sliding rod 13 is provided on one side of the first abutting rod 11 and the second abutting rod 12. There are two sliding rods 13 in total. The outer surfaces of the two sliding rods 13 are slidably connected to sleeves 14. There are two sleeves 14 in total. Both sleeves 14 are fixedly connected to the pipe sleeve 1.

[0049] It should be noted that the first abutting rod 11 and the second abutting rod 12 are both slidably connected to the pipe sleeve 1 through their corresponding sliding rods 13 and sleeves 14. This type of structure is simple and easy to manufacture and maintain.

[0050] In a more preferred embodiment, one end of the sliding rod 13 placed in the sleeve 14 is fixedly connected to the connecting rod 15, and the end of the connecting rod 15 away from the sliding rod 13 passes through one side of the sleeve 14 and is slidably connected to the sleeve 14. A handle 16 is provided at the end of the connecting rod 15 passing through the sleeve.

[0051] It should be noted that: through the handle 16, medical staff can manually control the sliding of the first abutment rod 11 and the second abutment rod 12 relative to the tube body 101, so as to manually adjust them when the transmission mechanism and the adjustment mechanism fail to control the movement state of the first abutment rod 11 and the second abutment rod 12.

[0052] Example 3:

[0053] See also Figure 1-4The post-pulmonary resection chest drainage tube provided in the present application includes all the contents of Examples 1-2 and their preferred embodiments. In addition, the adjustment mechanism 3 includes: a first elastic member 31, the first elastic member 31 is arranged in the sleeve 14, and the two ends of the first elastic member 31 are respectively fixedly connected to the sliding rod 13 and the sleeve 14; a base 32, the base 32 is arranged on one side of the sleeve 14; a shift rod 33, one side of the shift rod 33 is rotatably connected to the base 32 through a rotating shaft 34; a second elastic member 35, the two ends of the second elastic member 35 are respectively fixedly connected to the base 32 and the shift rod 33; a latch 36, the latch 36 passes through the base 32 and the sleeve 14, and is slidably connected to the base 32 and the sleeve 14, and one end of the latch 36 is rotatably connected to the shift rod 33; a plurality of limiting holes 37, each limiting hole 37 is opened on one side of the sliding rod 13, and each limiting hole 37 is adapted to one end of the latch 36.

[0054] It should be noted that: under normal circumstances, the first elastic member 31 acts to push the slide rod 13 toward the outside of the sleeve 14, that is, to push the first abutting rod 11 and the second abutting rod 12 fixedly connected to the slide rod 13 toward the tube body 101. The first elastic member 31 can be a spring, an elastic rubber block, or other structures;

[0055] When the lever 33 is rotated by the rotating shaft 34, the latch 36 is driven by the second elastic member 35 to move up and down along the sliding groove; under normal circumstances, the second elastic member 35 rotates one end of the lever 33 around the rotating shaft 34 in the direction away from the sleeve 14, thereby causing the latch 36 on the other side of the lever 33 to rotate in the direction toward the sleeve 14, so that one end of the latch 36 contacts the outer surface of the slide bar 13 in the sleeve 14, and by pressing the end of the lever 33 away from the latch 36, the other end of the latch 36 is lifted in the direction away from the slide bar 13; because the limiting holes 37 are all formed on one side of the slide bar 13 and the limiting holes 37 are all adapted to one end of the latch 36, when the latch 36 is just inserted into the limiting hole 37 on the outer surface of the slide bar 13, the sliding of the slide bar 13 under the action of the first elastic member 31 is limited;

[0056] By respectively setting the limiting holes 37 so that the slide rod 13 slides to different positions where the first abutting rod 11 and the second abutting rod 12 do not contact the tube body 101 / contact and squeeze the tube body 101 to form a semi-open and closed state / contact and completely squeeze and close the tube body 101, it is possible to press the lever 33 once to make the first abutting rod 11 and the second abutting rod 12 move toward the tube body 101 under the action of the first elastic member 31 and enter a semi-open and closed flow state, and press the lever 33 once more to fully close the tube body 101; in conjunction with the handle 16 in the above embodiment, pressing the lever 33 and pulling the handle 16 can achieve the resetting of the first abutting rod 11 and the second abutting rod 12.

[0057] In a preferred embodiment, a limiting plate 17 is provided on the outer surface of one end of the connecting rod 15 that passes through the sleeve 14 .

[0058] It should be noted that: when the sliding rod 13 drives the first abutting rod 11 and the second abutting rod 12 to slide toward the tube body 101 under the action of the first elastic member 31, the connecting rod 15 is driven synchronously. After sliding for a certain distance, the limiting plate 17 is acted upon by the end of the sleeve 14 to limit the maximum sliding distance of the connecting rod 15 and the sliding rod 13, thereby preventing the first abutting rod 11 and the second abutting rod 12 from excessively squeezing the tube body 101 and causing damage.

[0059] In a more preferred embodiment, the outer surface of the handle 16 is provided with anti-slip grooves.

[0060] It should be noted that the anti-slip pattern can help medical staff better grip the handle 16 and avoid hand slipping when resetting the first abutting rod 11 and the second abutting rod 12 through the handle 16 .

[0061] In a further preferred embodiment, the sleeve 14 is made of a transparent material.

[0062] It should be noted that by setting the sleeve 14 to a transparent material, medical staff can clearly see the sliding state of the slide rod 13 and whether the pin 36 is inserted into the limit hole 37. It can also facilitate relevant technical personnel to quickly and conveniently find the source of the fault when a fault occurs in the device.

[0063] Example 4:

[0064] See also Figure 1-4 The post-pulmonary resection chest drainage tube provided in this application includes all the contents of embodiments 1-3 and their preferred embodiments. In addition, a flexible part is provided on the side of the first abutment rod 11 and the second abutment rod 12 close to the tube body 101.

[0065] It should be noted that the flexible member can be made of materials such as gelatin sponge and silicone rubber to reduce the risk of damage caused by the first abutting rod 11 and the second abutting rod 12 squeezing the tube body 101 .

[0066] In a preferred embodiment, a handle is provided on one side of the sleeve 1 .

[0067] It should be noted that: medical staff can conveniently carry the tube sleeve 1 through the handle.

[0068] In summary, compared with the existing technology, the present invention has the following beneficial effects:
