Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a urinary catheter structure which is convenient for collecting clean and sterile urine specimens. Background Art

[0002] At present, with the increasingly serious aging of China, the problem of urinary retention in elderly patients is also increasing, and more and more patients need to insert a urinary catheter for treatment. In addition, in clinical practice, more and more patients with indwelling urinary catheters need to collect clean urine for auxiliary diagnosis such as routine urine tests and urine culture. In the prior art, when patients with indwelling urinary catheters collect clean urine, they usually adopt the method of replacing the urine bag connected to the urinary catheter or manually retaining it after a period of time by manually clamping a certain part of the urinary catheter. However, when the method of clamping the urinary catheter is adopted, if after clamping for a period of time, the time is busy and forget to open the clamping part of the urinary catheter, it will cause urinary retention in the patient, which will bring the risk of urinary retention and hematuria to the patient; when the method of replacing the urine bag is adopted, the urine bag is wasted, and the medical cost of the patient's urine bag is increased. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems and provide a urinary catheter structure which is convenient for collecting urine specimens. The structure is simple, the use is convenient and safe, and the patient will not experience urine retention or hematuria; the medical cost of the patient is reduced; and the working efficiency of medical staff is improved.

[0004] To achieve the above-mentioned purpose of the utility model, the utility model provides a urinary catheter structure that is convenient for collecting urine specimens, including a urinary catheter, and further comprising: a liquid retention joint arranged on the side wall of the urinary catheter and connected to the inner cavity of the urinary catheter; a urine collector detachably connected to the liquid retention joint of the urinary catheter, used to store urine in the urinary catheter temporarily diverted through the liquid retention joint; and a plug detachably connected to the liquid retention joint of the urinary catheter so that urine in the urinary catheter can selectively flow into the urine collector.

[0005] Preferably, the urinary catheter is also provided with a bladder insertion port and a urine bag connection port located at both ends thereof respectively and a bladder bag for fixing the urinary catheter located on one side wall thereof, and the liquid retention joint is arranged on the side wall opposite to the bladder for fixing the urinary catheter.

[0006] Preferably, the liquid retention connector is arranged on a side wall of the urinary catheter between the bladder insertion port and the water bag for fixing the urinary catheter.

[0007] Preferably, the liquid retention connector extends obliquely downward from the side wall of the urinary catheter.

[0008] Preferably, the urine collector has a connecting tube for connecting to the liquid retention connector.

[0009] Preferably, the liquid retaining joint has a butt joint for plugging and unplugging connection with the connecting pipe.

[0010] Preferably, the plug is connected to the butt joint by plugging.

[0011] Compared with the prior art, the urinary catheter structure of the utility model for facilitating the collection of urine specimens has the following advantages:

[0012] 1. The catheter structure of the utility model is convenient for collecting urine specimens, has a simple structure, is easy to use and safe, will not cause urine retention and hematuria in patients, reduces the cost of medical treatment for patients, and improves the work efficiency of medical staff. It has a wider range of applications and is more practical.

[0013] 2. The urinary catheter structure of the utility model is convenient for collecting urine specimens. When collecting urine, the plug sealed on the liquid collecting joint is opened, and the urine collector is connected with the liquid collecting joint, so that the urine in the urinary catheter is preferentially transferred to the urine collector without affecting the patient's normal urination into the urine bag, and the urine in the urinary catheter temporarily diverted by the liquid collecting joint is collected through the urine collector, so as to facilitate subsequent operations on the collected urine, and collecting urine is convenient and safe. When collecting urine is not needed, the plug is used to block the outlet of the liquid collecting joint and the urine collector is removed.

[0014] The utility model is described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 3 The utility model is a structural schematic diagram of a urine collector in a urinary catheter structure for conveniently collecting urine specimens. DETAILED DESCRIPTION

[0018] like Figure 2 , Figure 3 As shown, they are respectively a schematic diagram of the structure of the catheter and the plug when they are separated in the catheter structure for facilitating the collection of urine specimens of the utility model and a schematic diagram of the structure of the urine collector. It can be seen from the figure that the catheter structure for facilitating the collection of urine specimens of the utility model comprises a catheter 1, and further comprises: a liquid retention joint 5 arranged on the side wall of the catheter and connected to the inner cavity of the catheter; a urine collector 8 detachably connected to the liquid retention joint of the catheter, for storing urine in the catheter connected to the liquid retention joint and temporarily diverted; and a plug 6 detachably connected to the liquid retention joint of the catheter so that urine in the catheter can selectively flow into the urine collector.

[0019] Specifically, the utility model catheter is an improvement on the structure of the prior art catheter. Figure 1 As shown, the prior art urinary catheter structure comprises a urinary catheter 1, a bladder insertion port 3 located at the upper end of the urinary catheter for inserting into the patient's bladder, a urine bag connection port 4 located at the lower end of the urinary catheter for connecting a common anti-reflux urine bag (not shown in the figure), and a urinary bag connection port 4 located at a side wall of the urinary catheter (such as Figure 1 The urinary catheter on the left side wall is fixed with a water bag 2.

[0020] In order to make the catheter structure of the utility model convenient for collecting clean urine, the utility model provides a liquid retaining joint 5 on the side wall opposite to the catheter and the bladder for fixing the catheter. The height of the liquid retaining joint on the catheter is higher than the connection point between the bladder insertion port and the connection point between the bladder for fixing the catheter and the catheter, that is, the height is between the bladder insertion port and the connection point between the bladder for fixing the catheter and the catheter, and is close to the connection point between the bladder for fixing the catheter and the catheter.

[0021] Among them, Figure 2 As shown, the utility model liquid retention joint includes an outward extension section extending obliquely downward from the side wall of the catheter and an inner extension section extending from the starting end of the outward extension section into the inner cavity of the catheter. When designing, the outward extension section of the liquid retention joint can be a stepped tube, and the diameter of the end of the stepped tube is smaller than the diameter of the connection with the catheter. The small diameter section can be a butt joint extending in a direction perpendicular to the axial direction of the catheter, which can be detachably connected to the urine collector. The inner extension section is an approximately semicircular tube extending from the starting end of the lower tube wall of the large diameter section of the stepped tube toward the inner cavity of the catheter (see Figure 2 ), urine introduced from the bladder insertion port of the urinary catheter is received through the semicircular tube, so that urine flows into the step tube along the semicircular tube and then flows into the urine collecting tube through the step tube. Correspondingly, the urine collector 8 adopts a cylindrical tube, on which a connecting tube 9 for plugging and unplugging connection with the butt joint of the liquid retention joint is provided. During design, the diameter of the butt joint can be slightly smaller than the diameter of the connecting tube, so that the end of the connecting tube can be sleeved on the butt joint. The length of the inner extension section of the liquid retention joint extending into the urinary catheter can be equivalent to the radius of the urinary catheter. The sizes of the inner extension section and the outer extension section can be reasonably determined according to actual conditions, so that too much urine will not remain in the liquid retention joint.

[0022] In order to allow the urine in the urinary catheter to flow to the urine bag below when there is no need to retain urine, the utility model provides a plug 6 at the liquid retention joint, and the plug is plug-in connected to the butt joint. When designed, the plug is T-shaped, and its small diameter section can be inserted into the butt joint and fit tightly with it, or the small diameter section can also be sleeved outside the butt joint and fit tightly with it. In order to prevent the plug from loosening, the plug and the butt joint can also be connected by thread.

[0023] In addition, in order to prevent the plug from being lost after opening the plug, the plug can also be connected with the liquid retaining joint by the connecting band 7. During production, the connector and the liquid retaining joint can all adopt medical hose, and the connecting band is also made of flexible materials with telescopic performance, such as plastics or rubber etc.

[0024] The utility model is a urinary catheter structure that is convenient for collecting urine specimens. When urine needs to be collected, the plug sealed on the liquid collection joint is pulled out, and the liquid collection joint is connected to the connecting head on the urine collector. A part of the urine flowing into the urinary catheter is blocked by the inner extension section of the liquid collection joint and flows into the urine collector through the inner extension section, the outer extension section and the connecting head, so that the urine in the urinary catheter temporarily diverted by the liquid collection joint is collected through the urine collector, so that subsequent operations on the collected urine are convenient, fast and safe for clinical urine collection. At the same time, when collecting urine, if the urine collector is full, the urine can also flow into the urine bag to avoid urine retention. After the urine collection is completed, the urine collector is removed and the plug is blocked on the liquid collection joint. Even if a small part of urine flows into the liquid collection joint, most of the urine still flows into the urine bag, so that the urine bag does not need to be replaced when collecting urine, which reduces the burden on patients. In addition, the catheter structure of the utility model is simple to manufacture, easy and safe to use, and can effectively prevent urine retention in patients. It can be used for a long time, saving manpower and material resources, and has a wider range of applications and greater practicality.

[0025] Although the utility model is described in detail above, the utility model is not limited thereto, and technicians in this technical field can make modifications based on the principles of the utility model. Therefore, all kinds of modifications made according to the principles of the utility model should be understood to fall within the protection scope of the utility model.
