Abstract
Description
Technical Field
[0001] The invention belongs to the field of medical instruments, in particular to a disposable oil-filled anesthesia catheterization bag. Background Art
[0002] Catheterization is a routine operation in hospitals. Currently, hospitals generally use disposable sterile catheterization bags, also known as conventional catheterization bags, which can effectively assist medical staff in most catheterizations in clinical work. However, for patients with urethral diseases such as prostatic hyperplasia, urethral stenosis, urethral deformation, as well as children, patients with poor psychological quality, and patients with pain sensitivity, conventional catheterization bags may cause complications such as urethral pain, hematuria, urethral mucosal damage, and even catheterization failure during the use of catheterization. The reasons are as follows: The catheter of a conventional catheterization bag needs to be fully lubricated, and the paraffin cotton pads built into this type of catheterization bag are not sufficient for full lubrication, resulting in great friction resistance between the catheter and the urethra during catheterization, which further leads to the above complications.
[0003] For patients with urethral diseases, the urethra morphology changes. For example, in patients with prostatic hyperplasia, the bladder neck is too high, and the catheter is inserted into the prostatic fossa with the tip of the catheter at the 6 o'clock position of the internal opening of the bladder urethra. Repeated attempts are required to insert the catheter. During clinical operations, some medical staff use brute force to push the catheter, which may lead to the above-mentioned complications or even catheterization failure. During pediatric catheterization, children often cannot cooperate effectively, and patients cannot tolerate the catheterization process well and may resist, which may also lead to the above-mentioned complications. Similarly, patients with poor psychological quality and pain sensitivity may experience the above-mentioned complications during catheterization.
[0004] In order to solve the above problems, there are catheter injection devices in the prior art that use lipid lubricants to reduce the pain of patients. In order to avoid cross infection, such devices are all packaged in disposable packages. However, in order to facilitate the passage of grease, such devices are usually designed with a larger caliber to facilitate the filling and transportation of grease. When using such disposable injection devices, medical staff usually need to use a transition device to transport the grease, which not only makes it cumbersome for medical staff to fill the medicine but also wastes materials. Summary of the invention
[0005] In order to solve the above problems, the object of the present invention is to provide a urinary catheterization bag which is convenient for medical staff to fill medicine.
[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a disposable oil-injected anesthesia catheterization bag comprises a box body, a grille integrally processed in the box body, the grid grooves of the grille are respectively equipped with a catheter, a tube clamp, a perforated towel, 2 pieces of coated cloth and 2 pieces of gauze blocks, and the grid groove is also equipped with a pusher, the pusher comprises a hollow ball head filled with catheterization medicine and a nozzle connected to the catheter, a locking device is processed at the connection between the hollow ball head and the catheter, the locking device comprises a threaded groove located at the catheter and a tooth groove located on the inner surface of the hollow ball head, and the tooth groove is adapted to be connected with the groove shape.
[0007] The method for using the disposable oil-injected anesthesia catheterization bag is characterized by comprising the following steps:
[0008] S1, drug preparation, medical staff mix 6 parts of glycerin, 3 parts of sterile water and 1 part of lidocaine to prepare a urinary catheterization agent;
[0009] S2, drainage preparation, the medical staff rotates the connection between the hollow ball head and the nozzle until the two parts of the syringe are disconnected, and then the medical staff lifts the bottom of the hollow ball head so that the opening of the hollow ball head is located at the highest point of gravitational potential energy;
[0010] S3, drug mixing, the medical staff pours the catheterization medicine along the opening of the hollow ball head in turn, and then shakes the hollow ball head to fully mix the drugs;
[0011] S4, equipment connection, the medical staff rotates one end of the mouthpiece to connect with the hollow ball head, and the other end of the mouthpiece is connected to the catheter;
[0012] S5, drug infusion, medical staff injects drugs into the patient's urinary system by squeezing the hollow ball head
[0013] The following beneficial effects are achieved by adopting the above scheme:
[0014] 1. Compared with the integrally manufactured push syringe in the prior art, the present technical solution uses a detachable disposable push syringe, which facilitates medical staff to fill and mix drugs, saves the time required for drug filling, and enhances efficiency.
[0015] 2. Compared with the prior art that uses connectors to transition between detachable and assembled syringes, this technical solution uses threaded connection to load the syringe, which not only saves the material of the connector, but also improves the sealing when medical staff squeeze the syringe. At the same time, the groove on the surface of the ball head refluxes and blocks the catheterization agent, avoiding waste of the catheter.
[0016] 3. Compared with other types of injectors, this technical solution utilizes the method of medical staff squeezing the hollow ball head for injection, which has a simple structure and is easy to operate.
[0017] 4. Compared with the existing technology of using a nozzle to infuse medicine, this technical solution directly opens the hollow ball head for infusion, saving the injection needle for infusing the medicine, and the size of the nozzle can be refined during processing and manufacturing to avoid excessive flow of medicine through the nozzle during use and causing damage to the patient's urinary system.
[0018] 5. Compared with the existing technology that uses lipids as lubricants, this technical solution uses glycerin as a lubricant. Glycerin as a liquid lubricant facilitates extrusion and saves the time required for extrusion. At the same time, the fluid lubricant is gentler than lipid lubricants in expanding the patient's urethra, avoiding damage to the patient's urinary system.
[0019] 6. Compared with the prior art using other liquid lubricants, the glycerin in this technical solution has a significant lubricating effect and does not produce a chemical reaction with the silicone catheter.
[0020] 7. Compared with the prior art that uses glycerin as a lubricant, lidocaine is added to the present technical solution, which plays an anesthetic role and reduces the pain of the patient during the catheterization operation.
[0021] 8. Compared with the existing technology using other anesthetics, the lidocaine used for urethral surface anesthesia in this technical solution is significantly better than other commonly used anesthetic drugs, and the allergy rate is extremely low.
[0022] 9. Compared with the prior art using other anesthetics with low allergy, the lidocaine in this technical solution does not produce a chemical reaction after being mixed with glycerin, thereby improving the stability and shelf life of the catheterization agent.
[0023] Furthermore, a circumferential raised band is machined inside the hollow ball head, the height of the raised band is less than one quarter of the hollow ball head, and the raised band is located at the horizontal center axis of the hollow ball head.
[0024] Compared with the existing technology of directly using a hollow ball head to squeeze for catheterization, the present technical solution uses a raised band to limit the extrusion range of the hollow ball head. When the operator performs a pinching operation or a gripping and squeezing operation (mainly gripping and squeezing), when the hollow ball head is squeezed to the maximum deformation, the raised bands resist each other. At this time, the squeezed parts of the hollow ball head fit each other, but hollow arcs are formed on both sides of the squeezed part, which facilitates the catheterization agent located above the raised band to flow into the nozzle.
[0025] Furthermore, the cross section of the raised belt is a rectangle, and the raised belt includes two long axes parallel to each other, and the two long axes are connected with oblique axes arranged at intervals, and the oblique axes are distributed throughout the raised belt.
[0026] 1. Compared with the raised belts of other structures, this technical solution facilitates the medical staff to produce a tactile sensation when squeezing to the maximum limit, reminding the medical staff that the drug content in the injection is close to exhaustion.
[0027] 2. Compared with the prior art using annular structure raised belts, this technical solution uses an oblique axis to fill the gaps between the annular belts, avoiding drug retention and improving the use efficiency of catheterization drugs.
[0028] 3. Compared with the existing technology that uses other shapes for filling, the inclined axis of the technical solution allows medical staff to rub the hollow ball head back and forth after fitting. At this time, the inclined axis produces a frosted touch to the medical staff, and at the same time, vibration is generated inside the hollow ball head, and the catheterization medicine suspended on the inner wall of the hollow ball head vibrates and slides, avoiding waste of medicine and saving costs.
[0029] Furthermore, the nozzle is in the shape of a horizontally placed cylinder, the liquid inlet of the nozzle is connected to the hollow ball head, the material outlet of the nozzle is connected to the urinary catheter, and a flow suppression device is integrally manufactured inside the nozzle.
[0030] Furthermore, the flow suppression device includes radially arranged protrusions with a rectangular cross-section, the number of the protrusions is 2, and the protrusions are symmetrical along the central axis of the nozzle. The protrusions are located at the connection point between the nozzle and the catheter, and the height of the two protrusions is less than the diameter of the nozzle.
[0031] 1. Compared with the prior art without adding a protrusion, when the squeezed catheterization agent flows through the protrusion, the protrusion reduces the impact force of the catheterization agent and drains and diverts the catheterization agent to prevent the catheterization agent from spilling out of the catheter. At the same time, it also prevents the catheter and the nozzle from being separated due to excessive impulse of the water flow, thereby improving the sealing and reducing the impact of the catheterization agent on the patient's urinary system.
[0032] 2. Compared with the prior art that only adds a diversion device, the protrusion in this technical solution has a flow-blocking effect. Because in actual operation, the flow direction of the catheterization agent depends on the hydraulic pressure and the air pressure in the hollow ball head. When the medical staff stops kneading the hollow ball head, the catheterization agent will flow back. At this time, the protrusion blocks the refluxed agent, thereby improving the effect of catheterization.
[0033] Furthermore, the concentration of lidocaine is 3%-5%, and low-concentration local anesthesia is used to avoid damage to the patient's nerves.
[0034] After using the overall device, the following beneficial effects are produced: 1. The disposable oil-filled anesthesia catheter bag contains sufficient glycerin for lubrication and is directly injected into the urethra. During the insertion of the catheter, it can effectively reduce the friction of the urethra and urethra, relieve the patient's urethral pain and discomfort, further reduce urethral mucosal damage, and effectively reduce the above-mentioned complications.
[0035] 2. The disposable oil-filled anesthesia catheterization bag contains lidocaine (a commonly used anesthetic drug), which can effectively reduce the discomfort of children, patients with poor psychological quality, sensitive pain, etc., and cooperate with medical staff to perform catheterization, further reducing the above-mentioned complications.
[0036] 3. During the process of pushing glycerol and anesthetics in the disposable oil-injected anesthesia catheterization bag, the urethra can be effectively dilated. The operator can intuitively feel whether the patient's urethra is obviously narrowed or completely obstructed, so as to make further adequate preparations, effectively improve the success rate of catheterization, and reduce catheterization complications.

[0041] The following is further described in detail through specific implementation methods:
[0042] The reference numerals in the drawings of the specification include: box body 1, urinary catheter 2, tube clamp 3, hole towel 4, injection device 5, hollow ball head 501, raised belt 501a, nozzle 502, protrusion 502a, coated cloth 6, gauze block 7, disposable gloves 8, cotton sheet 9.
[0043] The embodiment is basically as shown in the attached Figure 1 and attached Figure 2 As shown: a disposable oil-injected anesthesia catheterization bag comprises a box body 1, a grille integrally processed in the box body 1, and the grid grooves are respectively equipped with a 8Fr catheter 2, a tube clamp 3, a hole towel 4, an injection device 5, a coated cloth 6, a gauze block 7, a disposable glove 8 and a cotton sheet 9, and the injection device 5 is made of a polymer ethylene material as a whole.
[0044] Please refer to Figure 2 The pusher 5 includes a hollow ball head 501 filled with a urinary catheterization agent and a mouthpiece 502 connected to the urinary catheter 2. A circumferential raised band 501a is processed inside the hollow ball head 501. The height of the raised band 501a is less than one-fourth of the hollow ball head 501, and the raised band 501a is located at the horizontal center axis of the hollow ball head 501. The cross section of the raised band 501a is rectangular. The raised band 501a includes two long axes parallel to each other. An oblique axis arranged at intervals is connected between the two long axes, and the oblique axis is fully distributed on the raised band 501a.
[0045] Please refer to Figure 3 and Figure 4The nozzle 502 is in the shape of a horizontally placed cylinder, the liquid inlet of the nozzle 502 is connected to the hollow ball head 501, the material outlet of the nozzle 502 is connected to the urinary catheter 2, and a flow suppression device is integrally manufactured inside the nozzle 502. The flow suppression device includes radially arranged protrusions 502a with a rectangular cross section, the number of the protrusions 502a is 2, and the protrusions 502a are symmetrical along the central axis of the nozzle 502, the protrusions 502a are located at the connection between the nozzle 502 and the urinary catheter 2, and the height of the two protrusions 502a is less than the diameter of the nozzle 502.
[0046] A locking device is processed at the connection between the hollow ball head 501 and the catheter. The locking device includes a threaded groove located at the catheter and a tooth groove located on the inner surface of the hollow ball head 501. The tooth groove is adapted to the shape of the groove.
[0047] The specific implementation process is as follows: the medical staff first prepares the catheterization medicine. At this time, the medical staff first takes out the syringe 5 in the catheterization bag, and then picks up the hollow ball head 501 in the syringe 5, so that the opening of the hollow ball head 501 is facing the medical staff. At this time, the medical staff pours 25 ml of glycerin into the hollow ball head 501, and then adds 4 ml of lidocaine preparation and 9 ml of sterile water. Finally, the medical staff shakes the mixed catheterization medicine in the hollow ball head 501.
[0048] When assembling the catheterization device and preparing the catheterization medicine, the medical staff holds the hollow ball head 501 so that the opening of the hollow ball head 501 faces upward, and then holds the nozzle 502 vertically. The medical staff aligns the threaded groove of the nozzle 502 with the tooth socket of the hollow ball head 501 and rotates it to assemble. During the assembly process, the medical staff gently pinches the hollow ball head 501 to fix the hollow ball head 501 while preventing the catheterization medicine in the hollow ball head 501 from overflowing. The nozzle 502 rotates to complete the assembly of the injector 5. At this time, the liquid outlet of the nozzle 502 is connected to the catheter 2 to complete the assembly of the catheterization device.
[0049] During the catheterization process, the medical staff connects the catheter 2 to the patient's urinary system for catheterization. At this time, the medical staff squeezes the hollow ball head 501 by holding it. When the volume of the hollow ball head 501 decreases, in order to maintain the hydraulic pressure in the hollow ball head 501, the catheterization medicine in the hollow ball head 501 is pressed out, and the pressed out catheterization medicine passes through the mouthpiece 502 and the catheter 2 in turn into the patient's urinary system. When the squeezed catheterization medicine flows through the protrusion 502a, the protrusion 502a reduces the impact of the catheterization medicine and drains and diverts the catheterization medicine to prevent the catheterization medicine from spilling out of the catheter 2, and also prevents the water flow from being too large to cause the catheter 2 and the mouthpiece 502 to separate, thereby improving the sealing and reducing the impact of the catheterization medicine on the patient's urinary system.
[0050] Because glycerol is added to the catheterization agent, the patient's urinary system is dilated and lubricated. At the same time, the lidocaine in the catheterization agent provides local anesthesia to the patient, reducing the pain during the catheterization process.
[0051] When the operator squeezes the hollow ball head 501 to the maximum deformation, the raised belts 501a are counteracted, and the squeezed parts of the hollow ball head 501 are fitted together. After the inclined axis is fitted, the medical staff can rub the hollow ball head 501 back and forth. At this time, the inclined axis produces a frosted touch to the medical staff, and at the same time, the hollow ball head 501 vibrates, and the urinary catheterization medicine suspended on the inner wall of the hollow ball head 501 vibrates and slides, avoiding the waste of medicine. At the same time, hollow arcs are formed on both sides of the squeezed part, which facilitates the urinary catheterization medicine located above the raised belt 501a to flow into the nozzle 502.
[0052] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
