Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a double-joint precision drainage bag. Background Art
[0002] A negative pressure drainage bag is a medical device, usually used to suck liquid and gas. It works by the principle of negative pressure, that is, by creating a low-pressure environment inside the bag to suck away the generated waste liquid, blood and harmful gases.
[0003] Most of the existing negative pressure drainage bags have only a single interface, which can only meet a single negative pressure suction operation at a time. During the negative pressure suction process, it is difficult to meet the actual use needs when it is necessary to suck liquid and gas simultaneously.
[0004] In addition, the overall material of the traditional negative pressure drainage bag is soft. After connecting the negative pressure, the bottom usually does not expand and fill, resulting in a large deviation in the reading of the sucked liquid. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a double-joint precision drainage bag that is convenient for exhaust and has accurate reading, effectively solving the problems raised in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solutions.
[0007] A double-joint precision drainage bag includes a drainage bag body, a rigid bottom support and a cover. The drainage bag body is composed of a folding section and a fixing ring. The folding section is fixed below the fixing ring. The rigid bottom support is fixed at the bottom end of the folding section. The cover is detachably installed above the fixing ring. A Y-shaped connector is installed on the cover. The Y-shaped connector has a first joint and a second joint. The folding section is evenly provided with creases in the vertical direction. The folding section can be folded up and down. Scale lines are provided on the outer wall of the folding section. The folding section is made of a transparent material.
[0008] It can be seen that the folding section can be folded. When storing, the folding section is folded and shortened to reduce the overall volume, which is convenient for storage and does not occupy too much space. When in use, the folding section is stretched to make the whole expand into a cylindrical shape. Connect the suction tube to the first joint or the second joint of the Y-shaped connector, and normal drainage work can be carried out. In addition, the folding section is made of a transparent material, and together with the scale lines, the amount of drained liquid can be read. In addition, when the first joint is connected to the suction tube, the second joint is convenient for exhausting the air in the drainage bag body. When the second joint is connected to the suction tube, the first joint can conveniently discharge the gas in the drainage bag body. In addition, because the rigid bottom support is made of hard material and can bear a large weight without deformation, when the whole drainage bag is filled with a large amount of drainage liquid, the whole bag body will not produce excessive deformation, thus ensuring accurate reading.
[0009] Furthermore, the rigid base is composed of a rigid ring and a rigid plate. The rigid plate is embedded and fixed inside the rigid ring. The rigid ring is fixed at the bottom of the folding section. Both the rigid ring and the rigid plate are made of rigid acrylic material.
[0010] The rigid ring and the rigid plate are made of rigid acrylic material. The rigid base formed by their combination has great hardness and is not easily deformed. Therefore, it can bear a large weight and provide effective support when the bag body touches it.
[0011] Furthermore, a single connector is also connected to one side of the Y-shaped connector on the cover. The single connector is used to connect to other equipment and instruments.
[0012] The single connector provides an additional connection position, facilitating connection to other instruments or equipment, and increasing the overall practicality of the drainage bag.
[0013] Furthermore, internal threads are provided on the inner wall of the fixing ring, and external threads that are thread-matched with the internal threads are provided on the outer peripheral wall of the cover. The cover is screwed onto the fixing ring through the thread fit of the external threads and the internal threads.
[0014] The cover is screwed onto the fixing ring through the thread fit of the external threads and the internal threads, achieving the detachable effect of the cover. Unscrewing the cover from the fixing ring can realize the disassembly of the cover, and thus it is convenient to remove the cover for internal cleaning.
[0015] Furthermore, a first sealing ring is fixed on the upper end surface of the fixing ring, and a second sealing ring is arranged on the cover. When the cover is screwed onto the fixing ring, the first sealing ring and the second sealing ring are in close contact correspondingly.
[0016] When the cover is tightened on the fixing ring, the first sealing ring and the second sealing ring are closely pressed and fitted, achieving a good sealing effect. Therefore, the overall sealing performance of the drainage bag is ensured, and air leakage is avoided, which may affect the negative pressure suction effect.
[0017] Furthermore, a first connecting strip is fixedly connected to the single connector, and a first rubber plug for blocking the single connector is fixed at the end of the first connecting strip. Second connecting strips are fixedly connected to both the first connector and the second connector, and second rubber plugs are fixed at the ends of the two second connecting strips. One of the second rubber plugs is used to block the first connector, and the other second rubber plug is used to block the second connector.
[0018] By inserting the first rubber plug into the port of the single connector, the single connector is blocked. Pulling out the first rubber plug from the port of the single connector can cancel the blocking of the single connector. Inserting the second rubber plug into the ports of the first connector and the second connector can block the first connector and the second connector. Pulling out the second rubber plug from the ports of the first connector and the second connector can cancel the blocking of the first connector and the second connector, meeting the actual use requirements.
[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows.
[0020] 1. By connecting a Y-shaped connector to the cover of the present utility model, two connection positions, namely the first connector and the second connector, are provided by the Y-shaped connector. When connecting the negative pressure suction tube at one connection position, the other connection position can facilitate the discharge of the gas in the bag body. At the same time, the two functions of negative pressure suction and exhaust are realized, meeting the actual use needs and having high practicability.
[0021] 2. The rigid bottom support in the present utility model is composed of a rigid ring and a rigid plate. The rigid ring and the rigid plate are made of rigid acrylic material, with a hard texture, capable of bearing a large weight without deformation. Therefore, when the entire drainage bag is filled with a large amount of drainage fluid, the entire bag body will not be overly deformed, thus ensuring accurate reading.
[0022] 3. The folding section in the present utility model can be folded. By stretching the folding section, the whole can be unfolded to form a cylindrical shape. Connecting the suction tube to the first connector or the second connector of the Y-shaped connector can perform normal drainage work. By folding and shortening the folding section, the overall volume can be reduced, facilitating storage and not occupying too much space. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will combine 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 them. Based on the embodiments of 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.
[0030] Please refer to Figures 1-5 , the utility model provides a double-joint precision drainage bag, including a drainage bag body 1, a hard bottom support 2 and a cover 3. The drainage bag body 1 is composed of a folding section 11 and a fixing ring 12. The folding section 11 is fixed below the fixing ring 12, the hard bottom support 2 is fixed at the bottom end of the folding section 11, and the cover 3 is detachably installed above the fixing ring 12. A Y-shaped connector 5 is installed on the cover 3. The Y-shaped connector 5 has a first connector 51 and a second connector 52. The folding section 11 is evenly distributed with folds in the vertical direction. The folding section 11 can be folded up and down, and the folding principle is the same as that of a foldable corrugated tube. A scale mark 101 is provided on the outer wall of the folding section 11, and the folding section 11 is made of a transparent material.
[0031] The folding section 11 is foldable. When storing, the folding section 11 is folded and shortened to reduce the overall volume, which is convenient for storage and does not take up too much space. When it is needed, the folding section 11 is lengthened to unfold the whole body and put it in a can. The suction tube is connected to the first joint 51 or the second joint 52 of the Y-shaped connector 5, and normal drainage work can be carried out. In addition, the folding section 11 is made of transparent material, and with the scale line 101, the amount of drainage liquid can be read. In addition, when the first joint 51 is connected to the suction tube, the second joint 52 is used to facilitate the exhaust of the drainage bag body 1. When the second joint 52 is connected to the suction tube, the first joint 51 can facilitate the exhaust of the drainage bag body 1. In addition, because the hard base 2 is made of hard material, it can withstand heavy weight without deformation. Therefore, when the entire drainage bag is filled with a large amount of drainage fluid, the entire bag body will not be excessively deformed, thereby ensuring accurate readings.
[0032] Specifically, the hard bottom bracket 2 is composed of a hard ring 21 and a hard plate 22. The hard plate 22 is embedded and fixed in the hard ring 21. The hard ring 21 is fixed at the bottom of the folding section 11. The hard ring 21 and the hard plate 22 are both made of hard acrylic material. The hard bottom bracket 2 formed by the hard ring 21 and the hard plate 22 is made of hard acrylic material. The hard bottom bracket 2 formed by the hard ring 21 and the hard plate 22 has high hardness and is not easy to deform, so it can bear a large weight and provide effective support when the bag body is in contact.
[0033] Specifically, a single connector 4 is also connected to one side of the Y-shaped connector 5 on the cover 3. The single connector 4 is used to connect to other equipment and instruments. By providing an additional connection position through the single connector 4, it is convenient to connect to other instruments or equipment, increasing the overall practicality of the drainage bag.
[0034] Specifically, an internal thread 121 is provided on the inner wall of the fixing ring 12, and an external thread 31 that is thread-matched with the internal thread 121 is provided on the outer peripheral wall of the cover 3. The cover 3 is screwed onto the fixing ring 12 through the thread cooperation of the external thread 31 and the internal thread 121. The cover 3 is screwed onto the fixing ring 12 through the thread cooperation of the external thread 31 and the internal thread 121, achieving the detachable effect of the cover 3. Unscrewing the cover 3 from the fixing ring 12 can realize the disassembly of the cover 3, and then it is convenient to remove the cover 3 for internal cleaning.
[0035] Specifically, a first sealing ring 122 is fixed on the upper end surface of the fixing ring 12, and a second sealing ring 32 is arranged on the cover 3. When the cover 3 is screwed onto the fixing ring 12, the first sealing ring 122 and the second sealing ring 32 are closely fitted correspondingly. When the cover 3 is tightened on the fixing ring 12, the first sealing ring 122 and the second sealing ring 32 are closely pressed and fitted, playing a good sealing effect, and then ensuring the overall sealing performance of the drainage bag and avoiding air leakage that affects the negative pressure suction effect.
[0036] Specifically, a first connecting strip 41 is fixedly connected to the single connector 4, and a first rubber plug 42 for blocking the single connector 4 is fixed at the end of the first connecting strip 41. Second connecting strips 53 are fixedly connected to both the first joint 51 and the second joint 52, and second rubber plugs 54 are fixed at the ends of the two second connecting strips 53. One of the second rubber plugs 54 is used to block the first joint 51, and the other second rubber plug 54 is used to block the second joint 52. By inserting the first rubber plug 42 into the port of the single connector 4, the blocking of the single connector 4 is realized. Pulling out the first rubber plug 42 from the port of the single connector 4 can cancel the blocking of the single connector 4. Inserting the second rubber plug 54 into the ports of the first joint 51 and the second joint 52 realizes the blocking of the first joint 51 and the second joint 52. Pulling out the second rubber plug 54 from the ports of the first joint 51 and the second joint 52 can cancel the blocking of the first joint 51 and the second joint 52, meeting the actual use requirements.
