[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0028] As described in the background technology, in the prior art, when the tank is filled with drainage fluid in the gastrointestinal tract, the traditional practice is to replace it with a new gastrointestinal decompression tank, which is bound to increase the patient's medical costs. At the same time, when taking laboratory specimens, the gastric tube and drainage tube need to be disconnected each time, increasing the workload of nursing staff.
[0029] Based on this, the utility model provides a negative pressure drainage device. Different from the traditional drainage device, the utility model has an openable and closable specimen collection port on the drainage tube, through which the specimen can be directly collected, avoiding disconnection of the gastric tube and the drainage tube. At the same time, a drainage bag is arranged under the tank body, and the drainage bag is connected and communicated with the inner cavity of the tank body. When the tank body is filled with drainage fluid, the drainage fluid is discharged to the outside through the drainage bag, thereby keeping the entire negative pressure drainage device clean and hygienic, and avoiding replacement of the drainage device, which increases the patient's medical costs.
[0030] The following is combined with specific Figure 1The structure of a preferred embodiment of the negative pressure drainage device of the present invention is described in detail.
[0031] like Figure 1 As shown, it is a structural schematic diagram of a preferred embodiment of the negative pressure drainer of the utility model. The negative pressure drainer includes a drainage tube 2 and a tank body 1. A compressible elastic member is installed in the tank body 1. The elastic member of this embodiment is preferably a spring 13.
[0032] One end of the drainage tube 2 is connected to the gastric tube and communicated with, and the other end is connected to the tank body 1 and communicated with the inner cavity of the tank body 1. Like the traditional tank body 1 structure, the tank body 1 includes a top cover 11 and a base 12. A soft plastic film is provided between the top cover 11 and the base 12. The soft plastic film is a columnar structure. The top of the soft plastic film is sealed and connected to the top cover 11, and the bottom of the soft plastic film is sealed and connected to the base 12. The spring 13 is installed in the columnar soft plastic film. When the top cover 11 is pressed downward, the soft plastic film is squeezed, and the spring 13 and the soft plastic film can both be deformed. The cavity in the soft plastic film forms a negative pressure cavity. During the rebound of the spring 13, the drainage fluid in the gastrointestinal tract is sucked out through the drainage tube 2 installed on the top cover 11.
[0033] The drainage tube 2 of this embodiment has a specimen collection port 21 which can be opened and closed. Figure 1 As shown, the specimen retention port 21 can be opened and closed by a plug, and the plug is preferably a rubber plug. When the needle of the syringe is inserted into the rubber plug, the rubber plug is deformed due to being squeezed and stretched open. The drainage fluid in the drainage tube is sucked outwards through the needle, thereby achieving the purpose of retaining the specimen and avoiding disconnection between the gastric tube and the drainage tube 2; when the needle of the syringe is pulled out of the rubber plug, the rubber plug returns to its original state, thereby achieving sealing of the specimen retention port 21.
[0034] In addition, for patients who need gastrointestinal decompression, a syringe can be used to inject medicine or saline into the openable and closable specimen collection port 21 of this embodiment once every two hours. The saline can prevent the drainage tube 2 from being blocked.
[0035] Continue to see Figure 1 As shown, the drainage tube 2 is provided with a first clamping member 22, which is used to control whether the drainage tube 2 is conductive. The first clamping member 22 is preferably a dovetail clamp, and can also be other types of clamps, which is not limited in the present invention.
[0036] When the patient has finished taking hemostatic drugs or certain drugs, the drainage tube 2 does not need to be drained to prevent the drugs from being drained into the tank body 1 and affecting the efficacy of the drugs. Therefore, the first clamping member 22 of this embodiment is used to clamp the drainage tube 2, so that the lumen of the drainage tube 2 is disconnected, and no drainage fluid passes through, and the tank body 1 stops being used.
[0037] In this embodiment, the first clamping member 22 is used to control the conduction of the drainage tube, thereby preventing the patient from being disconnected from the gastric tube after taking medicine, thereby reducing the workload of the nursing staff.
[0038] In addition, Figure 1 As shown, the present embodiment further includes a drainage bag 3, which is installed below the tank body 1 and is connected and communicated with the inner cavity of the tank body 1. The drainage fluid in the tank body 1 can be transferred to the drainage bag 3 under the action of gravity, thereby avoiding the need to replace a new drainage device after the tank body 1 is filled with drainage fluid, thereby saving the patient's expenses.
[0039] The drainage bag 3 of this embodiment is provided with scale lines 32 , and the amount of drainage fluid flowing into the drainage bag 3 is observed through the scale lines 32 .
[0040] In order to control the flow rate of drainage fluid from the tank body 1 to the drainage bag 3, a second clamping member 31 is provided on the input pipeline of the drainage bag 3. The second clamping member 31 is used to control whether the tank body 1 and the drainage bag 3 are connected. When the tank body 1 is full of drainage fluid, the second clamping member 31 can be released, and the drainage fluid in the tank body 1 automatically flows into the drainage bag 3 under the action of gravity.
[0041] As a preferred embodiment, a hook 14 is provided on the tank body 1, and the drain device can be hung beside the bed through the hook 14. However, ordinary drain devices are placed directly on the bed, occupying the space on the bed. This embodiment can avoid occupying the space on the bed by setting the hook 14 to hang the drain device.
[0042] The utility model also provides a gastrointestinal decompression device, including the negative pressure drainer provided in the above embodiment.
