Description

Technical Field

[0001] The utility model relates to a nursing device used in a medical environment, in particular to a collection device for clinically accurately measuring urine volume. Background Art

[0002] Accurate urine measurement is an important technical means for clinical diagnosis and assessment of patient conditions, especially during the period of fluid resuscitation for severe acute pancreatitis.

[0003] In clinical urinary catheterization care equipment, urine is usually measured by a urine storage bag connected to a urinary catheter. However, the urine storage bag connected to the urinary catheter is made of a transparent soft material, which is easy to deform, and the urine collection and measurement is inaccurate. It is only used for reference and is mainly used for general routine care that does not require high urine measurement accuracy.

[0004] Conventional urine storage bags connected to urinary catheters are difficult to meet the technical requirements for accurate urine measurement during fluid resuscitation of severe acute pancreatitis. The traditional practice is to frequently discharge the urine collected in the urine storage bag into a larger open container with scales within a set collection cycle (such as 12 hours as a cycle) for final measurement at the end of the collection cycle. This method is an open urine collection method. On the one hand, there are technical problems of environmental pollution and poor hygiene. On the other hand, there is a risk of the collection container being accidentally overturned, causing the collected urine to spill, and the stability is poor.

[0005] The applicant has searched the existing technologies for accurate urine volume measurement. Among the existing technologies known, the main technologies are to accurately measure urine with a metering cylinder connected to a urinary catheter and located upstream of a urine storage bag. For example, Chinese patent documents disclose technologies named "a urine collection device capable of accurately measuring urine volume", publication number CN 203208415 U, publication date September 25, 2013, "an alarm urine storage bag", publication number CN203107375 U, publication date August 7, 2013, and "an accurate measuring urine bag", publication number CN 201642489 U, publication date November 24, 2010. Although such technologies can achieve accurate urine volume measurement to a certain extent, the use effect is poor, mainly manifested in the following aspects:

[0006] The volume of the metering cylinder connected to the catheter is limited. During the collection period, the accompanying personnel or medical staff are required to open the valve more frequently to release urine and accumulate multiple measurement data of the metering cylinder, which leads to technical problems such as cumbersome operation and easy omissions.

[0007] In summary, in view of the clinical technical demand for accurate urine volume measurement and the shortcomings of existing technologies, it is necessary to design a collection device that is simple to operate, hygienic, and accurate in measurement. Utility Model Content

DETAILED DESCRIPTION

[0038] The utility model relates to a nursing device for medical environment, specifically a clinical accurate urine collection device, as shown below in conjunction with the accompanying drawings of the specification - Figure 1 and Figure 2 The technical solution of the utility model is clearly and in detail explained.

[0039] It should be noted that the drawings of the present invention are schematic, and unnecessary details have been simplified to clarify the technical purpose of the present invention, so as to avoid blurring the technical solution of the present invention in the prior art. In addition, the expressions "approximately" and "substantially" in the following text regarding quantity or matching relationship mean that reasonable assembly errors and processing errors in the industry are allowed to exist, and do not literally express absolute quantity or matching relationship.

[0040] See also Figure 1 and Figure 2 As shown, the utility model comprises a urine storage bag 1 and a urine collector 2.

[0041] Specifically, the urine storage bag 1 has a urinary catheter 11 and a urinary discharge tube 12. The urine storage bag 1 is a soft transparent structure, which is convenient for carrying the urinary catheter 11. A capacity scale is set on the bag wall of the urine storage bag 1, which is convenient for medical staff and supporting personnel to observe the patient's urination. The urinary catheter 11 is connected to the upper part of the urine storage bag 1, and the upstream end of the urinary catheter 11 is used to be placed on the patient. When urine is produced in the patient's body, the urine is drained through the urinary catheter 11 placed on the patient and introduced into the urine storage bag 1. The urinary discharge tube 12 is connected to the bottom of the urine storage bag 1 and is used to discharge the urine collected by the urine storage bag 1. In the present invention, the urinary tube 12 is used for quick-release connection with the drainage tube 21 on the urine collection container 2 described below. For the convenience of independent control, a manual valve 13 that can control its on / off state is connected to the urinary tube 12. When the patient needs to move and leave the urine collection container 2 beside the bed, the manual valve 13 can be closed to remove the urinary tube 12 from the urine collection container 2. During the process of the urine collection container 2 collecting the urine discharged from the urine storage bag 1, the urinary tube 12 needs to be sealed and connected to the drainage tube 21 of the urine collection container 2, and the manual valve 13 on the urinary tube 12 is opened, so that urine can flow into the urine collector 2 through the urinary tube 12 and the drainage tube 21 through the manual valve 13 in the open state for storage and measurement.

[0042] The end of the above-mentioned urination tube 12 has a quick-release joint 211, and the hardness of the quick-release joint 211 is greater than the hardness of the main body of the urination tube 12, which is convenient for hand-held force operation. The quick-release joint 211 is an inner joint structure. In the connection structure with the drainage tube 21 of the urine collection container 2, the inner wall of the quick-release joint 211 can tightly wrap the joint at the front end of the drainage tube 21 to form a sealed connection. The inner wall of the quick-release joint 211 has multiple circumferentially formed sealing rings arranged along the axial spacing. Each sealing ring is a flexible and deformable structure, and each sealing ring sequentially forms a variable diameter structure in which the outer end diameter is larger than the inner end diameter in the axial direction of the quick-release joint 211. In the quick-release joint 211 of the above-mentioned structure, in the sealed connection with the drainage tube 21 of the urine collection container 2, each sealing ring on the inner wall of the quick-release joint 211 circumferentially contacts the joint at the front end of the drainage tube 21, and gradually transitions from a loose contact fit at the outer end to a tight fit at the inner end.

[0043] The top of the urine collection container 2 is provided with a drainage tube 21, and the front end of the drainage tube 21 is provided with a joint of a hard structure. The joint at the front end of the drainage tube 21 is sealedly connected to the urine discharge tube 12 of the urine storage bag 1 by the above-mentioned detachable structure.

[0044] The urine collection container 2 is a transparent hard structure, which has a barrel section, a cone section and a drainage joint, the barrel section is located on the top side of the cone section, and the drainage joint is located on the bottom side of the cone section. The top side of the barrel section of the urine collection container 2 is a closed structure, through which a drainage tube 21 and a handle 29 are connected, and it is used to assemble the display alarm 27 described below with a sealed and waterproof structure. The drainage joint of the urine collection container 2 is used to seal and connect the urination tube 23. On the container wall in the height direction of the aforementioned urine collection container 2, a capacity scale is provided, and medical staff or accompanying personnel can visually view the urine level collected by the urine collection container 2 through the capacity scale on the urine collector 2. Since the lower part of the urine collection container 2 is a cone section structure, in order to ensure the stability of the seat, a support 22 located outside the cone structure is connected to the urine collection container 2, and the urine collection container 2 sits on the support plane through the support 22.

[0045] The second urination tube 23 connected to the urine collecting container 2 is located at the bottom of the conical structure of the urine collecting container 2. A urination valve 24 for controlling the on / off state of the second urination tube 23 is connected. The conical design can discharge the urine in the urine collector 2 to the greatest extent and reduce the residue.

[0046] In order to improve the metering accuracy and convenience of the urine collection container 2, the urine collection container 2 has an electronically controlled structure connected to the urine discharge pipe 23. Correspondingly, an electronic liquid level meter 25 is provided in the urine collection container 2. The electronic liquid level meter 25 is used to detect the liquid level of the urine collected in the urine collection container 2. The electronic liquid level meter 25 is connected to a controller 26.

[0047] The controller 26 is connected to a communication unit 28, a display alarm 27 and a urination valve 24. The controller 26 is used to obtain the urine level signal collected by the electronic liquid level meter 25, and output an opening instruction to the urination valve 24 at the set maximum allowable liquid level (i.e., the maximum collection volume of the urine collection container 2) or the collection cycle (e.g., 12 hours is a collection cycle). That is, when the urine collected in the urine collection container 2 has reached the maximum allowable liquid level before the collection cycle is full, the controller 26 should output an alarm signal and control the urination valve 24 to open; or, when the urine collected in the urine collection container 2 has not reached the maximum allowable liquid level after the collection cycle is full, the controller 26 should also output an alarm signal and control the urination valve 24 to open. When the urine collected in the urine collection container 2 is emptied and reaches the set minimum allowable liquid level, the urine collection container 2 forms a space that allows the next collection cycle, and the controller 24 should output a closing instruction to the urination valve 24.

[0048] The display alarm 27 connected to the controller 26 is arranged on the top side of the urine collection container 2 in a waterproof structure. The controller 26 outputs a liquid level measurement signal and an alarm prompt signal to the display alarm 27 at a collection cycle or a set maximum allowable liquid level to prompt the accompanying personnel. The controller 26 is connected to the nurse station monitoring platform 210 signal through a communication unit 28 (such as a WIFI network or a 5G network, etc.). The controller 26 outputs a liquid level measurement signal and an alarm prompt signal to the nurse station monitoring platform 210 at a collection cycle or a set maximum allowable liquid level to prompt the accompanying personnel.

[0049] It should be noted that the above-mentioned electronic liquid level meter, controller, communication unit, etc. all adopt existing conventional technologies. For example, the controller adopts a control circuit board or a PLC programmable controller. The technical contribution of the utility model lies in the combination of the above-mentioned structures, rather than the design of the above-mentioned electronic devices. These electronic devices themselves are applications of existing technologies.

[0050] The above specific technical solutions are only used to illustrate the present invention, rather than to limit it.

[0051] Although the present invention has been described in detail with reference to the above-mentioned specific technical solutions, those skilled in the art should understand that they can still modify the specific technical solutions in the above-mentioned specific technical solutions, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the present invention.
