Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a drainage device for nursing. Background Art

[0002] When a drainage tube is usually used, one end of the catheter is inserted into the drainage part of the patient's body or wound surface. By using the siphon principle, pus, exuded blood, tissue fluid and other liquids accumulated between human tissues or in body cavities are guided to the outside of the body to prevent postoperative infection caused by liquid stasis.

[0003] When draining the body fluid in a patient through a drainage tube, since the amount, composition and internal pressure of the body fluid in the patient are unknown, when draining through the drainage tube, if the inner diameter of the drainage tube is large, the body fluid in the patient may be discharged at too fast a speed, causing a certain burden on the patient. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drainage device for nursing, so as to solve the technical problem that the drainage flow rate of the drainage tube in the prior art cannot be adjusted.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] As Figure 1 shown, the present utility model provides a drainage device for nursing. The drainage pipe 8 is used to draw out liquid from the interior of the fluid to be drained;

[0031] The casing 1 is sleeved outside the drainage pipe 8;

[0032] The housing 2 is arranged on the casing 1 and has an opening facing the drainage pipe 8;

[0033] The elastic membrane 3 covers and is sealingly connected to the opening, and naturally contracts without external force;

[0034] The pressure assembly is arranged inside the housing 2 and is used to apply pressure to the elastic membrane 3 to make the elastic membrane 3 expand to squeeze the drainage pipe 8 so as to reduce the internal flow rate of the drainage pipe 8.

[0035] During use, the elastic membrane 3 is driven to expand or contract by the pressure assembly. When the elastic membrane 3 expands, the elastic membrane 3 squeezes the drainage pipe 8, so that the drainage pipe 8 is squeezed and contracted, and then the liquid flow rate in the drainage pipe 8 decreases. When the elastic membrane 3 contracts, the drainage pipe 8 returns to its original state, and then the liquid flow rate in the drainage pipe 8 increases.

[0036] Thus, when draining through the drainage pipe 8, the suction flow rate of the accumulated liquid in the drainage pipe 8 can be adjusted in real time, so that the accumulated liquid in the patient's body is discharged stably, avoiding harm to the patient.

[0037] In this embodiment, with reference to Figure 2As shown, the pressure assembly includes a first airbag 4 disposed within a housing 2. An inflation assembly 5 is provided on the housing 2 for inflating the first airbag 4. The inflation assembly 5 inflates the first airbag 4, causing the elastic membrane 3 to expand.

[0038] An exhaust pipe 401 is connected to the first airbag 4, and a sealing plug is threadedly installed within the exhaust pipe 401. The first airbag 4 is exhausted through the exhaust pipe 401, causing the first airbag 4 to contract.

[0039] In this embodiment, the inflation assembly 5 includes a second airbag 501. An intake pipe 503 for supplying air to the second airbag 501 is connected to the second airbag 501. A charging pipe 502 through which the second airbag 501 supplies air to the first airbag 4 is connected between the first airbag 4 and the second airbag 501.

[0040] By repeatedly squeezing the second airbag 501, external air is pumped into the first airbag 4 through the second airbag 501 and the charging pipe 502, causing the first airbag 4 to expand.

[0041] In this embodiment, check valves for restricting the flow direction of gas within them are provided in both the charging pipe 502 and the intake pipe 503.

[0042] Among them, the check valve in the charging pipe 502 only allows the gas within the second airbag 501 to enter the first airbag 4 through the charging pipe 502, and the check valve in the intake pipe 503 only allows external air to enter the second airbag 501 through the intake pipe 503.

[0043] When draining the accumulated fluid, there is a limit to the amount of fluid drained each time. If there is too much accumulated fluid in the patient's abdominal cavity, drainage needs to be carried out again after a certain period of time. Therefore, after the patient's single - time accumulated fluid is drained, the drainage tube 8 is usually sealed to wait for the next drainage.

[0044] However, for patients whose conditions have not been fully cured, the accumulated fluid in the abdominal cavity will continue to increase. Especially for abdominal effusion caused by liver function impairment, connective tissue diseases, etc., after eating or having a fever, the accumulated fluid in the abdominal cavity will increase rapidly, and the pressure within the patient's body will also increase rapidly. At this time, it is necessary to promptly open the drainage tube 8 for drainage. However, since the accumulated fluid is inside the patient's body, neither the patient nor the staff can accurately grasp the pressure state of the abdominal effusion. For this reason, we propose the following solutions to solve the above problems:

[0045] In this embodiment, referring to Figure 2 As shown, a monitor for monitoring the internal pressure of the drainage tube 8 is provided on one side surface of the elastic membrane 3 close to the liquid outlet end of the drainage tube 8.

[0046] When the elastic membrane 3 expands to cut off and seal the inside of the drainage tube 8, the pressure inside the drainage tube 8 is monitored in real time by a monitor. When the pressure of the accumulated fluid in the patient's abdominal cavity exceeds the preset threshold inside the monitor, the monitor sends out a warning signal to the outside to remind the staff to open the drainage tube 8 to drain the fluid from the patient's abdominal cavity.

[0047] In order to achieve the above process, in this embodiment, the specific implementation manner of the monitor is as follows:

[0048] The monitor includes a piezoelectric sheet 6 disposed on one side surface of the elastic membrane 3 close to the liquid outlet end of the drainage tube 8 for monitoring the pressure of the drainage tube 8 on the elastic membrane 3. A controller 7 and a warning device are also installed on the sleeve 1. The controller 7 is communicatively connected to the warning device and the piezoelectric sheet 6.

[0049] Among them, the monitor is arranged at the connection between the elastic membrane 3 and the sleeve 1. When the elastic membrane 3 expands, after the elastic membrane 3 expands to seal the drainage tube 8, the deformation amount at this place is small, and the side wall of the piezoelectric sheet 6 fits with the deformable part of the drainage tube 8.

[0050] When the middle part of the drainage tube 8 is sealed by the elastic membrane 3 and the accumulated fluid in the patient's abdominal cavity increases and the pressure increases, the pressure inside the drainage tube 8 gradually increases, the pressure exerted by the tube wall of the drainage tube 8 on the piezoelectric sheet 6 increases, and the piezoelectric signal transmitted by the piezoelectric sheet 6 to the controller 7 is enhanced. When the intensity of this piezoelectric signal exceeds the preset threshold inside the controller 7, the controller 7 drives the warning device to send out a warning signal to the outside to remind the staff to open the drainage tube 8 to drain the fluid from the patient's abdominal cavity.

[0051] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
